ACE inhibition with ramipril improves left ventricular function at rest and post exercise in patients with stable ischaemic heart disease and preserved left ventricular systolic function.

AIMS: To assess the effects of 6 months intervention with +ramipril on resting and post exercise left ventricular function in patients with stable ischaemic heart disease and preserved left ventricular systolic function. METHODS AND RESULTS: Patients (n=98, age 65+/-9 years, 37% women) were randomized to double-blind treatment with ramipril 5 mg. day(-1)(n=32), ramipril 1.25 mg. day(-1)(n=34), or placebo (n=32). Resting and post maximum exercise echocardiography/Doppler examinations were performed at baseline and after 6 months. Changes over 6 months in resting transmitral E-wave deceleration time (Edt) and Edt adjusted for heart rate (Edt/RR) differed between the ramipril 5 mg, ramipril 1.25 mg, and placebo groups: Edt 24+/-82, -1+/-69, and -29+/-64 ms, respectively, P=0. 012; Edt/RR 30+/-105, 2+/-61, and -28+/-69 ms, respectively, P=0.015. Changes in the difference between resting and post exercise Edt/RR also varied between groups: -53+/-137, -28+/-118, and 35+/-101 ms, respectively, P=0.029. No differences in E/A indices were noted. Resting atrioventricular plane displacement improved in the combined ramipril groups vs the placebo group: 0.2+/-0.8 vs -0.2+/-1.3 mm, P<0.05.Conclusion Six months ramipril treatment in patients with stable ischaemic heart disease and preserved left ventricular systolic function improved resting left ventricular function and reduced the exercise induced diastolic filling abnormalities usually seen in these patients.

[Heart failure after myocardial infarction: diagnosis, treatment, prevention. Echocardiography should be a routine procedure in myocardial infarction].

Post-infarction prognosis is considerably impaired if left ventricular systolic dysfunction and/or symptomatic heart failure develops. As the symptoms of left ventricular dysfunction are often subtle or completely lacking, such patients can be identified only by objective evaluation of left ventricular function. However, as symptoms of heart failure may develop despite normal left ventricular function, objective evaluation of left ventricular function is also important in symptomatic patients, since prognosis is especially poor in the presence of systolic dysfunction. As echocardiography is the most suitable and accessible method in the context, also allowing assessment of cardiac dimensions and valvular function, its extended use in post-infarction patients is imperative. Left ventricular dysfunction should be prevented by adequate measures to limit the extent of infarction and prevent its recurrence. To improve prognosis, the use of ACE (angiotensin converting enzyme) inhibitors should be considered whenever left ventricular dysfunction is present, irrespective of symptomatology. Treatment with amiodarone has recently been shown to reduce mortality among patients with post-infarction heart failure, and should also be considered in such cases, especially if there is a need of antiarrhythmic therapy. Although beta-receptor blockers have well-documented beneficial effects in myocardial infarction, their effect on patients with latent or overt heart failure has not been specifically studied. The use of angiotensin II antagonists in patients with post-infarction heart failure or left ventricular dysfunction is currently under investigation.

Exercise training in heart failure improves quality of life and exercise capacity.

AIMS: Benefit from exercise training in heart failure has mainly been shown in men with ischaemic disease. We aimed to examine the effects of exercise training in heart failure patients < or = 75 years old of both sexes and with various aetiology. METHODS AND RESULTS: Fifty-four patients with stable mild-to-moderate heart failure were randomized to exercise or control, and 49 completed the study (49% > or = 65 years; 29% women; 24% non-ischaemic aetiology; training, n = 22; controls, n = 27). The exercise programme consisted of bicycle training at 80% of maximal intensity over a period of 4 months. Improvements vs controls were found regarding maximal exercise capacity (6 +/- 12 vs -4 +/- 12% [mean +/- SD], P < 0.01) and global quality-of-life (2 [1] vs 0 [1] units [median ¿inter-quartile range¿], P < 0.01), but not regarding maximal oxygen consumption or the dyspnoea-fatigue index. All of these four variables significantly improved in men with ischaemic aetiology compared with controls (n = 11). However, none of these variables improved in women with ischaemic aetiology (n = 5), or in patients with non-ischaemic aetiology (n = 6). The training response was independent of age, left ventricular systolic function, and maximal oxygen consumption. No training-related adverse effects were reported. CONCLUSION: Supervised exercise training was safe and beneficial in heart failure patients < or = 75 years, especially in men with ischaemic aetiology. The effects of exercise training in women and patients with non-ischaemic aetiology should be further examined.

Assessment of left ventricular dysfunction and remodeling by determination of atrioventricular plane displacement and simplified echocardiography.

Heart failure is a common disease characterised by poor prognosis and frequent hospitalisations, constituting a major economic burden to society. Mortality and morbidity can be reduced by optimal treatment, requiring objective evaluation of cardiac function and anatomy. The development of symptomatic HF can be prevented by initiating adequate treatment in early stages when LVD is still asymptomatic. Asymptomatic patients can be identified only by screening for LVD among patients at risk of developing HF, such as those with IHD, HT, and diabetes. However, there is a severe lack of resources to assess cardiac function and anatomy in all patients at risk. Consequently, many patients with latent HF will remain undetected, and in patients with symptomatic HF treatment will not be optimal. Simplified echocardiography, a 5-minute echocardiogram based on visual estimation of cardiac function and anatomy, is an inexpensive and accurate method for diagnosis and screening for latent and symptomatic HF. The long axis shortening of the LV is related to LV function and can be measured by AVPD. Determination of left AVPD is a reliable, reproducible, readily mastered, quickly performed and, therefore, inexpensive method that can be used in almost all patients for evaluation of LV function, as well as for prognostication in HF. Left AVPD reflects both systolic and diastolic LV function. Simplified echocardiography is useful for screening of asymptomatic patients at risk of developing HF, and for routine diagnostic purposes in patients with symptoms suggestive of HF. In patients with LVSD, simplified echocardiography may be combined with a determination of left AVPD for prognostication and for optimal detection of changes in LV function over time.

Quality of life in patients with ischaemic heart disease: a prospective controlled study.

OBJECTIVES: To assess quality of life in patients after acute myocardial infarction (AMI), coronary artery by-pass grafting surgery (CABG) and percutaneous transluminal coronary angioplasty (PTCA) as compared with healthy controls. DESIGN: Self-administered questionnaires were completed 1 month and 1 year after the event. SETTING: Department of Cardiology, University Hospital, Malmö, Sweden; 1989-1992. SUBJECTS: 296 AMI, 99 CABG, 18 PTCA patients and 88 randomly selected healthy controls were included; 349 patients completed the entire programme. MAIN OUTCOME MEASURES: Quality of life in the dimensions of perceived general health, thoracic pain, breathlessness, feeling of arrhythmia, anxiety, depression, self-esteem, experience of social life and sex life. RESULTS: Patients differed from controls in both psychological and somatic aspects of QL after 1 month. Furthermore, 1 month after the event AMI patients experienced more anxiety (P = 0.001) than CABG patients, whilst CABG patients experienced a poorer sex life (P < 0.001) than AMI patients. One year after the event patients differed from controls primarily in somatic symptoms: no significant differences were found across patient groups. Patients who sought emergency out-patient care during the follow-up year for clinically diagnosed angina pectoris or cardiac incompensation had reported higher levels of thoracic pain (P < 0.001) and breathlessness (P < 0.001) at 1 month follow-up than patients who did not seek such care. CONCLUSIONS: Quality of life is considerably affected in patients following a cardiac event, especially during the initial recovery phase. Although substantial improvement in quality of life occurs over time, the persistence of residual distress at 1-year follow-up is a challenge for clinicians concerned with the full rehabilitation of the cardiac patient.

Left ventricular atrioventricular plane displacement: an echocardiographic technique for rapid assessment of prognosis in heart failure.

OBJECTIVE: To assess the prognostic value of atrioventricular plane displacement in heart failure patients. DESIGN: Patients were followed prospectively for one year after atrioventricular plane displacement determination. SETTING: Malmö University Hospital, with a primary catchment area of 250,000 inhabitants. PATIENTS: 181 patients with a clinical diagnosis of heart failure; age 75.7 (SD 5.2) years, duration of heart failure 2.7 (5.7) years; 100 men, 81 women. MAIN OUTCOME MEASURES: Mortality in relation to atrioventricular plane displacement. RESULTS: Total mortality was 22.7% (41/181), and was highly significantly (P = 0.001) related to atrioventricular plane displacement. Mortality within prospectively defined categories of displacement was: > or = 10.0 mm, 0% (0/19); 8.2 to 9.9 mm, 10.3% (3/29); 6.4 to 8.1 mm, 19.4% (12/62); and < 6.4 mm, 36.6% (26/71). The groups were similar in age, sex, angiotensin converting enzyme inhibitor and beta blocker treatment, and cause and duration of heart failure. CONCLUSIONS: Mortality in heart failure is strongly related to atrioventricular plane displacement.

Comparison of the effects of losartan and enalapril on clinical status and exercise performance in patients with moderate or severe chronic heart failure.

OBJECTIVES: This study assessed the feasibility of an efficacy trial comparing angiotensin-converting enzyme inhibition and angiotensin II receptor antagonism in heart failure. Patients with moderate or severe heart failure whose condition had previously been stabilized by treatment with a converting enzyme inhibitor were randomly assigned to receive enalapril or losartan. The study was designed to detect any signs of clinical deterioration during double-blind treatment. BACKGROUND: Losartan is a specific, nonpeptide angiotensin II receptor-1 antagonist with a vasodilator hemodynamic profile similar to that of converting enzyme inhibitors. Although therapy with specific receptor blockade has certain theoretic advantages over nonspecific converting enzyme inhibition, demonstration of a comparable therapeutic effect in patients with congestive heart failure will require a major effort comparing two active agents. METHODS: One hundred sixty-six patients with stable heart failure in New York Heart Association functional class III or IV and an ejection fraction < or = 35% were included in a multicenter, double-blind, parallel, enalapril-controlled trial. After a 3-week stabilization period with optimal therapy, including digitalis, diuretic drugs and a converting enzyme inhibitor, patients were randomly assigned to 8 weeks of therapy with losartan, 25 mg/day (n = 52); losartan, 50 mg/day (n = 56); or enalapril, 20 mg/day (n = 58). Patients were assessed with frequent clinical and laboratory evaluation and exercise testing. RESULTS: No significant differences between groups in terms of changes in exercise capacity (6-min walk test), clinical status (dyspnea-fatigue index), neurohumoral activation (norepinephrine, N-terminal atrial natriuretic factor), laboratory evaluation or incidence of adverse experience were observed. CONCLUSIONS: The results suggest that losartan and enalapril are of comparable efficacy and tolerability in the short-term treatment of moderate or severe congestive heart failure. A trial designed to compare the efficacy, tolerability and effect on mortality of long-term angiotensin II receptor blockade with converting enzyme inhibition is both feasible and ethically responsible.

[Need for a long-term program in the follow-up of anti-lipid treatment following coronary artery surgery?].

The positive effects of cholesterol-lowering therapy in coronary artery disease are well recognised. This study, on 99 consecutive coronary artery bypass grafted patients, shows that an intensive one-year follow-up at a secondary prevention specialist clinic significantly improves cholesterol levels compared to conventional follow-up in the primary health care system. However, these positive results are not consistent after a 2.6 year return to the primary health care. Consequently, improved collaboration between hospital and primary health care physicians in the development of structured secondary prevention programmes is essential.

Statistical significance versus clinical relevance in cardiovascular medicine.

Evidence-based medicine is the foundation of everyday clinical practices and large clinical trials investigating the effects of various interventions on morbidity and survival and generally provide the most robust evidence. Cardiovascular medicine is considered one of the most evidence-based disciplines of medicine. However, there are a number of limitations to the general applicability of clinical trial results in cardiovascular medicine. Although generally useful to the clinician, clinical trials have often been suboptimally designed from 1 or several points of view. As a consequence of flaws in the design and the execution of the trials, statistical significance is quite often not equal to clinical relevance. This article outlines some of the shortcomings of designing and carrying out clinical trials, as well as inadequacies concerning the publication, interpretation, and implementation of the trial results. Evidence-based medicine is obviously not always as solid as one might think.
