The influence of calcium and magnesium in drinking water and diet on cardiovascular risk factors in individuals living in hard and soft water areas with differences in cardiovascular mortality.

BACKGROUND: The role of water hardness as a risk factor for cardiovascular disease has been widely investigated and evaluated as regards regional differences in cardiovascular disease. This study was performed to evaluate the relation between calcium and magnesium in drinking water and diet and risk factors for cardiovascular disease in individuals living in hard and soft water areas with considerable differences in cardiovascular mortality. METHODS: A random sample of 207 individuals living in two municipalities characterised by differences in cardiovascular mortality and water hardness was invited for an examination including a questionnaire about health, social and living conditions and diet. Intake of magnesium and calcium was calculated from the diet questionnaire with special consideration to the use of local water. Household water samples were delivered by each individual and were analysed for magnesium and calcium. RESULTS: In the total sample, there were positive correlations between the calcium content in household water and systolic blood pressure (SBP) and negative correlations with s-cholesterol and s-LDL-cholesterol. No correlation was seen with magnesium content in household water to any of the risk factors. Calcium content in diet showed no correlation to cardiovascular risk factors. Magnesium in diet was positively correlated to diastolic blood pressure (DBP). In regression analyses controlled for age and sex 18.5% of the variation in SBP was explained by the variation in BMI, HbA1c and calcium content in water. Some 27.9% of the variation in s-cholesterol could be explained by the variation in s-triglycerides (TG), and calcium content in water. CONCLUSIONS: This study of individuals living in soft and hard water areas showed significant correlations between the content of calcium in water and major cardiovascular risk factors. This was not found for magnesium in water or calcium or magnesium in diet. Regression analyses indicated that calcium content in water could be a factor in the complexity of relationships and importance of cardiovascular risk factors. From these results it is not possible to conclude any definite causal relation and further research is needed.

New-onset diabetes and risk of all-cause and cardiovascular mortality: the Cardiovascular Health Study.

OBJECTIVE: Cardiovascular risk associated with new-onset diabetes is not well characterized. We hypothesized that risk of all-cause and cardiovascular mortality would be similar among participants with and without new-onset diabetes in the first years of follow-up and rise over time for new-onset diabetes. RESEARCH DESIGN AND METHODS: The Cardiovascular Health Study (CHS) is a longitudinal study of cardiovascular risk factors in adults aged > or =65 years. We used CHS participants to define a cohort (n = 282) with new-onset diabetes during 11 years of follow-up. New-onset diabetes was defined by initiation of antidiabetes medication or by fasting plasma glucose >125 mg/dl among CHS participants without diabetes at study entry. Three CHS participants without diabetes were matched for age, sex, and race to each participant with new-onset diabetes at the time of diabetes identification (n = 837). Survival analysis provided adjusted hazard ratios (HRs) for all-cause and cardiovascular mortality. RESULTS: During a median of 5.9 years of follow-up, there were 352 deaths, of which 41% were cardiovascular. In adjusted analyses, new-onset diabetes was associated with an HR of 1.9 (95% CI 1.4-2.5) for all-cause and 2.2 (1.4-3.4) for cardiovascular mortality compared with no diabetes. Mortality risks were elevated within 2 years of onset, especially cardiovascular risk (4.3 [95% CI 1.7-10.8]), and did not increase over time. CONCLUSIONS: Our findings indicate that there may be a mortality differential soon after diabetes onset in older adults and suggest that long-term macrovascular damage from atherosclerosis may not be primarily responsible for increased risk.

[Lipoprotein(a) in children with hypercholesterolemia as a marker of the familial history of cardiovascular risk. The Working Group on Cardiovascular Risk Factors in Childhood and Adolescence].

OBJECTIVE: To evaluate the levels of lipoprotein (a) (Lp(a)) as a marker of familiar history of cardiovascular risk. MATERIAL AND METHODS: We have studied 176 children and adolescents between the ages of 3 and 18 years with hypercholesterolemia. In these children we determined Lp(a) levels and collected the family history concerning cardiovascular risk factors (hypercholesterolemia and cardiovascular disease under 55 years of age). RESULTS: Of the cases studied, 67.04% had a family history of cardiovascular risk. In this group, levels of Lp(a) were significantly higher than in the group without a family history of cardiovascular risk. Lp(a) levels higher than 30 mg/dl were found in 3.44% of the patients without a family history of cardiovascular risk in contrast to 28,43% and 37.5% of the cases with familiar history of hypercholesterolemia and cardiovascular disease, respectively. CONCLUSIONS: The levels of lipoprotein (a) in children and adolescents with hypercholesterolemia are a marker of family history of cardiovascular disease and hypercholesterolemia.

Cardiovascular morbidity and mortality in community-dwelling elderly individuals with calcification of the fibrous skeleton of the base of the heart and aortosclerosis (The Cardiovascular Health Study).

In the elderly, mitral annular calcification (MAC) and aortic valve sclerosis (AVS) are associated with increased cardiovascular morbidity and mortality. Aortic annular calcification (AAC) commonly occurs with MAC. However, the prognostic value of AAC, singly or in combination with MAC and AVS, for incident cardiovascular disease and mortality is unknown. From the Cardiovascular Health Study, we analyzed 3,782 participants (76 +/- 5 years of age, 60% women) who had an echocardiogram at the 1994 to 1995 examination and who were prospectively followed for an average of 6.6 years (range 0.01 to 8.5). All 3 calcification categories were associated with incident congestive heart failure (MAC: hazard ratio [HR] 1.71, 95% confidence interval [CI] 1.35 to 2.18, AAC: HR 1.62, 95% CI 1.28 to 2.06, and AVS: HR 1.50, 95% CI 1.19 to 1.89) and death. A stronger association with incident cardiovascular disease and mortality was observed with a larger number of calcification categories and with increased MAC severity. Moreover, in the participants with prevalent cardiovascular disease at echocardiographic examination (n = 1,054), MAC and AAC were still associated with cardiovascular mortality (MAC: HR 1.91, 95% CI 1.04 to 3.50; AAC: HR 2.11, 95% CI 1.16 to 3.85) even in fully adjusted models. In conclusion, MAC, AAC, and AVS are associated with a significant risk of incident congestive heart failure, cardiovascular and all-cause mortalities, and worse outcome in older patients with preexisting cardiovascular disease. Elderly patients with these findings represent a high-risk group and may require close medical attention.

Anger inhibition, cardiovascular recovery, and vagal function: a model of the link between hostility and cardiovascular disease.

A model of the association between hostility and cardiovascular disease (CVD) is proposed based upon anger inhibition, slow cardiovascular recovery, and low parasympathetic activity (vagal tone). This model is opposed to the more conventional model that emphasizes anger expression, cardiovascular reactivity, and high sympathetic tone. We argue that in social reality, incidences of anger inhibition outnumber incidences of anger expression to a great extent, irrespective of preferred expression style. Moreover, slow cardiovascular recovery, rather than high reactivity, may be the mechanism underlying the CVD risk associated with anger inhibition. Both anger inhibition and slow cardiovascular recovery are associated with a persistently low vagal tone. Thus, the anger inhibition/vagal inhibition model seems more consistent with the actual nature of anger in daily life and with the known cardiovascular control mechanisms. The model may better account for the chronic pathophysiological state that is believed to lead to CVD. Importantly, an experimental inhibition/recovery paradigm might also allow to test potential behavioral and cognitive accelerators of cardiovascular recovery. As an example of an important socially-mediated health risk that may be elucidated using the anger inhibition/vagal inhibition model, we discuss Black-White differences that have been found in CVD.

Information and communication technology in cardiovascular disease prevention in developing countries: hype and hope. Report of the International Collaboration on Information Use in Cardiovascular Health Promotion in Developing Countries.

Information can be an important tool in promoting a prevention strategy to address the emerging epidemic of cardiovascular disease in developing countries. Advances in information and communication technology offer new promises for global access to information and for global mobilization to prevent and control cardiovascular disease. This is especially true for health professionals, whose needs in areas such as networking, exchange of expertise and access to relevant advances remain unfulfilled. Information technology can also sensitize the lay public to the magnitude of cardiovascular diseases, creating awareness about risk states, and highlighting preventive strategies. Effective application mandates that the technology be relevant to local needs. Cost, feasibility, and relevance of information need to be considered before wide adoption is advocated. Several initiatives, such as ProCOR, Global Cardiovascular Infobase, Heartfile, and the Virtual Congress of Cardiology, have successfully utilized information technology to promote cardiovascular prevention. The experience of these initiatives suggests that, while information technology holds great potential, there are many potential perils, such as the widening global information gap, inequitable access, and irrelevant information. For now, information technology must be viewed as part of a broader strategy, which includes conventional communication media, to address the unmet information needs for cardiovascular prevention globally. Enlightened policies can exploit the energies of the recent information boom for promoting cardiovascular prevention, taking into account the considered limitations.

Influence of cardiovascular diseases upon the results of the cardiovascular reflex tests in diabetic and nondiabetic subjects.

Cardiovascular reflex tests are used to assess cardiac autonomic neuropathy in diabetes mellitus. Cardiovascular diseases (CVD) are known to alter baroreflex mechanisms. Diabetic patients are at a high risk for cardiovascular complications. In order to prove whether cardiovascular diseases reduce the diagnostic value of the cardiovascular reflex tests in diabetic autonomic neuropathy unselected groups of 274 nondiabetic and 103 diabetic patients were studied: E/I, 30/15, and Valsalva ratios, sustained handgrip test and blood pressure response to standing. Both groups were subdivided into young (less than or equal to 45 years) and older (greater than 45 years) patients and into subjects with and without CVD. In young nondiabetic patients with CVD, E/I and Valsalva ratios were significantly lower than in those without CVD. In young diabetic patients with CVD, only E/I ratios were significantly reduced compared to those without CVD. The tests reflecting sympathetic nerve function did not differ between patients with and without CVD, neither in the nondiabetic nor in the diabetic subjects. In the older nondiabetic and diabetic patients, cardiovascular reflexes were generally impaired, but did not show any difference between subjects with and without CVD. In young diabetic patients suffering from CVD, the diagnostic value of cardiovascular reflex tests is reduced as far as cardiac autonomic neuropathy is concerned. In older patients, the tests are not suitable for the diagnosis of diabetic autonomic neuropathy. More specific methods are required.

Learning from large cardiovascular clinical trials: classical cardiovascular risk factors.

The number of cardiovascular risk factors significantly influences age adjusted cardiovascular death rates according to the data of the MRFIT Trial. Up to 60% of patients with Type 2 diabetes have concomitant hypertension. In the HOT (Hypertension Optimal Treatment) Study lowering of blood pressure was particularly beneficial in the subgroup of diabetes mellitus: there was a 51% reduction in major cardiovascular events in target group<or=80 mmHg, compared with target group<or=90 mmHg (p=0.005). Analysis of the diabetic patient group in the CAPPP (The CAPtopril Prevention Project) showed that captopril was superior for preventing cardiovascular events in hypertensive patients with diabetes. In the diabetic cohort of the LIFE Study losartan was more effective than athenolol in reducing cardiovascular morbidity and mortality as well as mortality from all causes in patients with hypertension, diabetes and left ventricular hypertrophy. In the Heart Protection Study 5963 people with diabetes were studied. For the first occurrence of any major vascular events among diabetic participants, there was a 22% reduction in the event rate simvastatin-allocated versus placebo allocated patients (p<0.0001). DAIS (Diabetes Atherosclerosis Intervention Study) data suggest that treatment with fenofibrate reduces the angiographic progression of coronary artery disease in patients with Type 2 diabetes. According to results on multifactorial intervention in patients with Type 2 diabetes (the STENO-2 study) the overall cardiovascular risk reduction was 53%. In conclusion, management of cardiovascular risk factors should be considered as the cornerstone of diabetes care.

High incidence of cardiovascular disease and increased prevalence of cardiovascular risk factors in women with hypopituitarism not receiving growth hormone treatment: preliminary results.

Recently, epidemiological evidence has suggested that hypopituitarism with untreated growth hormone deficiency (GHD) is associated with a high incidence of cardiovascular mortality and that women are particularly at risk. In the present study, the incidence of cardiovascular disease and prevalence of cardiovascular risk factors in 33 such women was assessed and compared with matched controls. A significantly higher number of diagnosed circulatory disorders occurred in the women with hypopituitarism compared with controls, and drug consumption for cardiovascular disorders was also significantly higher in this group. Furthermore, patients with hypopituitarism had a significantly higher waist:hip ratio and a higher ratio of low-density lipoprotein to high-density lipoprotein than controls. Electrocardiogram data showed that hypopituitarism was associated with more episodes of bradycardia. In summary, women with hypopituitarism had an increased incidence of cardiovascular disease and a less favourable risk factor profile compared with matched controls. The data add support to previous studies that have shown increased risks of cardiovascular mortality associated with hypopituitarism with untreated GHD. We conclude that adequate cardiovascular surveillance programmes are required for patients with pituitary insufficiency.

Improvement of cardiovascular risk profile in an elderly population of low social level: the ICON (Improving Cardiovascular risk profile in Older Neapolitans) study.

Older age and low socio-economic conditions are associated with poor control of cardiovascular risk factors (RFs). We assessed the prevalence and awareness of cardiovascular RFs in 503 elderly outpatients of low social status attending two public Internal Medicine clinics in Naples, and studied the interaction of education and employment level with risk profile. The therapeutic intervention was oriented to improve patients' motivation through a positive patient-physician relationship, in keeping with the current guidelines for hypertension. The effect of treatment was evaluated by comparing retrospectively the level of cardiovascular RFs at baseline and at the last follow-up examination performed within 31 October 2005. Only 33.3% of patients (age=68+/-6 years) had attended primary school. Overall (current or previous) employment level was also low. Obesity, hypertension and dyslipidaemia were present in most patients, diabetes in 17.3% of them. In all 8.0% of hypertensives, 16.1% of diabetics and 24.7% of dyslipidaemiacs were unaware of their diseases. Cardiovascular risk profile was worse at lower educational and employment levels. Odds ratios for the metabolic syndrome were 0.28 (95% confidence interval (CI)=0.15-0.52) and 0.35 (0.20-0.62) in the most qualified of three education and employment groups, respectively, compared to the lowest ones. The level of all cardiovascular RFs was effectively reduced during treatment. Control rate of most RFs improved significantly (for hypertension, from 12.8 to 36.5%, P<0.001). These patients had a high prevalence of cardiovascular RFs, which correlated with their educational and work activity levels. Awareness of their health status was unsatisfactory. Treatment, specifically addressing patient-physician relationship, favourably affected cardiovascular risk profile.

C-reactive protein: associations with haematological variables, cardiovascular risk factors and prevalent cardiovascular disease.

C-reactive protein (CRP) has been proposed as a risk factor for cardiovascular disease; however, this association is confounded by mutual relationships with both classical and haematological cardiovascular risk factors. We, therefore, measured CRP with a high-sensitivity assay in stored plasma samples from 414 men and 515 women in the north Glasgow MONICA (MONItoring trends in CArdiovascular diseases) survey, to study its correlation with haematological variables, classical risk factors and prevalent cardiovascular disease. CRP correlated with age, oral contraceptive use, menopause and most classical cardiovascular risk factors (except blood pressure). CRP also correlated with plasma levels of the pro-inflammatory cytokine interleukin 6, and haematocrit, viscosity, red cell aggregation, white cell count, and coagulation factors [fibrinogen, factor (F) VII in women, FVIII, FIX] and inhibitors (antithrombin and protein C in women; protein S) but not coagulation activation markers. CRP was significantly associated with prevalent cardiovascular disease in both men (P = 0.03) and women (P = 0.009), however, the association became non-significant after adjustment for firstly classical risk factors, then fibrinogen. We conclude that correlations with classical and haematological risk factors account for a substantial component of the association of CRP with prevalent cardiovascular disease, but there is evidence of a residual, independent effect among women.

Microalbuminuria is common, also in a nondiabetic, nonhypertensive population, and an independent indicator of cardiovascular risk factors and cardiovascular morbidity.

OBJECTIVES: To assess the prevalence of microalbuminuria in the general population, especially in nondiabetic and nonhypertensive subjects, and its association with known cardiovascular risk factors and cardiovascular morbidity. DESIGN: Cross-sectional cohort study. SETTING: Inhabitants of the city of Groningen, the Netherlands. SUBJECTS: All inhabitants, aged between 28 and 75 years, were send a postal questionnaire and a vial to collect an early morning urine sample (n = 85 421). Of these 40 856 subjects (47.8%) responded. Cardiovascular risk factors and morbidity were validated in a well defined nondiabetic and nonhypertensive group of 5241 subjects. MAIN OUTCOME MEASURES: Microalbuminuria, self-reported cardiovascular risk and cardiovascular morbidity in the total study cohort, and additionally more detailed measurements in a subset of the total population. RESULTS: Microalbuminuria (20-200 mg L-1) was present in 7.2% of the subjects and independently associated with age, gender, hypertension, diabetes, smoking, previous myocardial infarction and stroke. Some of these associations were already observed at albuminuria levels of 10-20 mg L-1. After exclusion of the diabetic and hypertensive subjects, microalbuminuria was still prevalent in 6.6% of the subjects. CONCLUSIONS: Microalbuminuria appears to be common not only in the general population but also in a nondiabetic, nonhypertensive population and is independently associated with increased cardiovascular risk factors and cardio-vascular morbidity. Importantly, some of these associations are present at urinary albumin levels currently considered to be normal. These findings suggest that urinary albumin measurements may be useful in early risk profiling and prevention of cardiovascular disease in the population at large.

How does minor renal dysfunction influence cardiovascular risk and the management of cardiovascular disease?

This review focuses on the association between mild renal insufficiency (stage 2 and 3 of chronic kidney disease) and cardiovascular disease and discusses therapeutic options. Although the association of chronic renal insufficiency and cardiovascular risk was first shown in patients with end-stage renal disease, even minor renal dysfunction is now established as an independent risk for atherosclerotic cardiovascular disease. The association has been established in patients with a high cardiovascular risk but also in the general population. Treatment with angiotensin-converting enzyme inhibitors and statins can reduce cardiovascular morbidity and mortality in patients with renal insufficiency. Coronary revascularization improves the prognosis in patients with minor renal dysfunction, but there is still an underutilization of coronary revascularization procedures in people with renal insufficiency. The use of coronary stenting has now reduced the incidence of restenosis in these patients, and there is hope that the development of new devices will improve the prognosis in patients with renal insufficiency as well. Nevertheless, people with cardiovascular disease and renal insufficiency die significantly more often than people without renal insufficiency independent of prior successful treatment. Further investigations should focus on the causes of and possible preventive interventions for the staggering cardiovascular risk in the ever-increasing number of people with minor renal dysfunction.

A national survey of cardiovascular physicians' beliefs and clinical care practices when diagnosing and treating depression in patients with cardiovascular disease.

A national survey was administered to determine 1) cardiovascular physicians' beliefs about the association between depression and cardiovascular disease (CVD), 2) the methods used to diagnose depression, 3) referral patterns for treatment of depression, and 4) frequency of use and preferred choice of antidepressant. A national survey of 50% of randomly selected U.S. cardiovascular physicians belonging to the American College of Cardiology was conducted; 796 of 8854 physicians who received the questionnaires responded. Cardiovascular physicians were aware of indirect associations between depression and coronary artery disease (CAD). However, 49.9% were unaware of depression as an independent cardiac risk factor; 71.2% asked less than half their patients with CAD about depression; 79% used no standard screening method to diagnose depression. Among cardiovascular physicians, 84.8% reported that between 1% and 50% of their patients have depression, and 49.2% indicated that they treat the symptoms of depression in their patients with CAD. Cardiovascular physicians often refer depressed patients with CAD to mental health professionals and recommend exercise, relaxation training, stress management, psychotherapy, and diaries for their patients. Among cardiovascular physicians, 55.5% treat depression/CAD with antidepressant medication: sertraline (28%), paroxetine (16.1%), fluoxetine (10.8%), escitalopram (8.7%), citalopram (7.9%), bupropion (4.4%), tricyclic antidepressants (3.8%), and venlafaxine 2.9%.

Association of fibrinogen with cardiovascular risk factors and cardiovascular disease in the Framingham Offspring Population.

BACKGROUND: Fibrinogen has been identified as an independent risk factor for cardiovascular disease and associated with traditional cardiovascular risk factors. Also, the role of elevated fibrinogen in thrombosis suggests that it may be on the causal pathway for certain risk factors to exert their effect. These associations remain incompletely characterized. Moreover, the optimal fibrinogen assay for risk stratification is uncertain. METHODS AND RESULTS: In 2632 subjects from cycle 5 of the Framingham Offspring Population, fibrinogen levels were determined with a newly developed immunoprecipitation test (American Biogenetic Sciences) and the functional Clauss method. With the immunoprecipitation method, there were significant linear trends across fibrinogen tertiles (P:<0.001) for age, body mass index, smoking, diabetes mellitus, total cholesterol, HDL cholesterol, and triglycerides in men and women. The Clauss method had significant results (P:<0.030), except for triglycerides in men. Fibrinogen levels were higher for those with compared with those without cardiovascular disease. After covariate adjustment, fibrinogen remained significantly higher in those with cardiovascular disease with the use of the immunoprecipitation test (P:=0.035 and P:=0.018 for men and women, respectively) but not with the Clauss method. CONCLUSIONS: Fibrinogen was associated with traditional cardiovascular risk factors. Elevation of fibrinogen may provide a mechanism for risk factors to exert their effect. Also, fibrinogen levels were higher among subjects with cardiovascular disease compared with those without disease. The immunoprecipitation test showed a stronger association with cardiovascular disease than the Clauss method, suggesting that it may be a useful screening tool to identify individuals at increased thrombotic risk.

Hypopituitary females have a high incidence of cardiovascular morbidity and an increased prevalence of cardiovascular risk factors.

We recently reported that female patients with hypopituitarism receiving controlled thyroid and steroid hormone substitution, but without GH replacement, had a more than 2-fold increase in cardiovascular mortality compared to the general population. In the present study we investigated the incidence of cardiovascular disease as well as the prevalence of cardiovascular risk factors in 33 females with hypopituitarism for 6-46 yr (median, 18) compared to those in 33 control subjects recruited from the general population in the same geographical area and matched for sex, age, smoking habits, educational level, and residence location. The patients were with a very high probability GH deficient, as 29 had subnormal serum insulin-like growth factor I levels, and the other 4 were GH deficient, as assessed by an insulin tolerance test. The incidence of cardiovascular disease was significantly higher among the hypopituitary patients (incidence ratio, 3.7; 95% confidence interval, 1.2-11.3), and the consumption of cardioactive drugs was also significantly higher (P = 0.002). Hypopituitary patients had a lower degree of physical exercise during their spare time (P = 0.02), a higher waist/hip ratio (P = 0.01), lower high density lipoprotein cholesterol (P = 0.002), and higher low density/high density lipoprotein ratio (P = 0.009). Furthermore, the patients had a significantly increased left atrium size (P = 0.05), but no difference was observed for other cardiac measures. In the patients, serum insulin-like growth factor I levels significantly correlated with left ventricular mass index (r = 0.48; P = 0.006), suggesting that GH has a strong impact on cardiac size. More episodes of bradycardia (P = 0.05), but no increased occurrence of extrasystolies, were encountered in the patients during 24-h continuous electrocardiogram monitoring. Carotid artery intima-media thickness and plaque numbers did not differ between patients and controls. In conclusion, hypopituitary females exhibit an increased incidence of cardiovascular disease, higher cardioactive drug consumption, and an increased prevalence of cardiovascular risk factors. The increased cardiovascular morbidity could not be ascribed to inadequate estrogen or thyroid hormone treatment, and unsubstituted GH deficiency is probably an important contributing factor.

Cardiovascular risk factors and probability for cardiovascular events in HIV-infected patients: part I. Differences due to the acquisition of HIV-infection.

OBJECTIVE: Due to side effects, such as hyperlipidaemia and insulin resistance, there is an increasing concern that antiretroviral drugs lead to an epidemic of cardiovascular diseases in HIV-infected patients. The present study characterizes the cardiovascular risk profile of HIV-infected individuals, due to the acquisition of HIV-infection. METHODS: Cardiovascular risk factors of 309 HIV-infected adults (HIV-acquisition: 59.2% by homosexual contact (group 1), 28.5% by heterosexual contact (group 2), 9.1% by intravenous drug abuse (group 3) and 3.2% by blood transfusion (group 4)) were analysed. Overall 10-years probability for cardiovascular events was analysed by the Framingham algorithm. RESULTS: Tobacco use was more common in group 1 subjects compared with group 2 subjects (67% vs. 52%; p<0.05). Additionally, group 1 subjects exhibited elevated total cholesterol (5.6 +/- 0.1 mmol/L vs. 4.8 +/- 0.3), LDL-cholesterol (3.6 +/- 0.1 mmol/L vs. 2.8 +/- 0.2) and triglyceride concentrations (3.2 +/- 0.3 mmol/L vs. 1.7 +/- 0.2) compared with group 3 (all p<0.05). No significant differences between the groups were detected in glucose metabolism. The overall 10-years probability for cardiovascular events was significantly higher in group 1 compared with group 2 and group 3 (12.2 +/- 0.8% vs. 6.6 +/- 0.9% and 7.9 +/- 1.6%, p<0.05). CONCLUSIONS: The cardiovascular risk profile differs between subgroups of HIV-infected individuals, leading to significant higher probability of cardiovascular events in group 1 subjects. The risk of premature atherosclerosis by HIV-infected individuals and therapeutic options remains to be established.

Familial occurrence in cardiovascular diseases. Familial cardiovascular diseases (1).

Current knowledge and assumptions about inherited cardiovascular diseases are reported in this review. They are examined from two different points of view. In the first section (familial cardiovascular diseases) discussion will center on the main cardiovascular diseases that have a definite clinical and pathophysiological feature in which familial occurrence has been extensively demonstrated. The genetic aspects of the primary cardiomyopathies, mitral valve prolapse, arrhythmias and conduction disturbances, long QT syndromes and abnormalities of ventricular repolarization, cardiovascular malformations, coronary artery disease, essential hypertension and rheumatic fever will be examined. In the second section (cardiovascular involvement in genetic disorders) discussion will be confined to the inherited multisystem disorders involving the cardiovascular system that most frequently occur in clinical practice. Currently known cardiovascular findings in relationship to chromosomal aberrations, connective tissue disorders, metabolic and enzymatic disorders, neuromuscular disorders and other rarer syndromes will be reported.
