[Enzymatic markers in the alcoholic cardiomyopathy].

Alcoholic cardiomyopathy can ensue from heavy consumption of alcohol over a long period of time. The clinical features include dilatation of the left ventricle, poor myocardial contractility with reduced left ventricular ejection volume, raised tissue enzymes. In numerous experimental data has been observed increased generation of oxygen and ethanol free radicals, indicate that free radicals are implied in myocardial and hepatic damage. Ethanol administration also elicits hepatic disturbances in the availability of antioxidant defense. The resulting antioxidative stress leads to enhanced lipid peroxidation and can also affect other important cellular component.

[Nebivolol treatment in essential arterial hypertension].

Nebivolol is a lipophilic beta 1-blocker. It is devoid of intrinsic sympathomimetic or membrane stabilising activity but appears to have nitric oxide-mediated vasodilatory effects. Nebivolol 5 mg once daily is well tolerated in patients with hypertension. Adverse events are infrequent, transient and mild to moderate. Those reported most often include headache, fatigue, paraesthesias and dizziness. Several studies reported no signs of orthostatic hypotension with Nebivolol.

[The implications of thromboembolism in chronic heart failure].

The goal of investigation was to determine whether long-term anticoagulant therapy influences the mortality rate in CHF. The method consisted in the calculation of the annual death rate of the patients with CHF class III-IV NYHA: group A (controls)--who did not receive anticoagulant or antiplatelet therapy; group B--treated with Acenocumarol or Aspirin. The results show in group A, which included 150 patients, during the 5-year interval under study 30 deaths, representing an annual death rate of 4%. In group B, which included 325 patients of which 75 treated with Acenocumarol and 250 patients with aspirin, 20 deaths were recorded during the same 5-year interval, representing an annual death rate of 1.2%. Thus, the mortality risk proved to be 70% lower in group B than in the control group. It came out that the main mechanism of death in CHF is thrombembolism and in this circumstance anticoagulant or antiplatelet therapy would be essential.

[Some aspects regarding degenerative mitral valvular lesions encountered in medical practice].

In the last years, the degenerative valvular heart diseases have the tendency to equalize in frequency the rheumatismal valvular diseases. The maximum attention has been paid on the degenerative aortic stenosis as being a lesion with maximum frequency and a severe evolution. This study, given on the 18391 admissions in the period 1997-2001, is a retrospective analyse and it is concerned with the degenerative mitral valvular lesions. Of the 223 patients with degenerative valvular heart lesions, 139 patients (62.3%) had degenerative aortic stenosis and 96 patients (38.5%) were diagnosed with degenerative mitral valvular lesions from which 30 patients have had no association with aortic valvular lesions while 66 patients have had such an association. The pointed out types of mitral lesions were: the mitral insufficiency in 59 patients, the mitral annular calcification without hemodynamic disease in 19 patients, the mitral stenosis in 9 patients and the mitral disease in 9 patients, too. The women was affected nearly 1.7 times more frequent than the men, with a maximum average age greater with four years for women but with a low minimal average age at 60 years for women and 52 years for men. The detailed analyse of this 96 cases had shown the presence of a cholesterol value over 200 mg/dl in 50 patients (52%), the diabetic mellitus of type II in 12 patients (12.5%), an association with HTA in 42 patients (43.7%), the cardiac insufficiency in 68 patients (70.8%), a permanent atrial fibrillation in 24 patients (25%), the chronical myocardiac infarct in 19 patients (19.7%) and disorders in the transmission of stimuli in 8 patients (8.3%). The degenerative mitral valvular lesions had occurred more and more frequently realizing more complex features under the mitral insufficiency predominance. Its frequent association with the degenerative valvular lesions determines the evolutive and therapeutic particularities that are dominated by the high gravity prognostic.

[Analysis of some clinical aspects of degenerative valvular heart diseases in medical practice].

UNLABELLED: In a period of 5 years there were 18,391 admissions; out of them 1129 cases were diagnosed with valvular lesions: 223 (19.7%) were degenerative valvular heart disease, 608 (53.8%) had rheumatismal valvular lesions, 7 (0.6%) had congenital valvular lesions and 291 cases (25.7%) had valvular lesions of other etiologies. Out of the 223 cases with degenerative valvular lesions, 99 cases (44.4%) were men with an average age of 70.1 years old and 129 were women (55%) with an average age of 74.9 years old. The calcific aortic valve stenosis was encountered in 139 patients (62.3%), the aortic insufficiency was diagnosed in 19 patients (8.5%), the mitral insufficiency 49 patients (21.9%) and the mitral stenosis in 10 patients (4.4%) the other patients having either aortic or mitral valvular disease. The combination of an aortic stenosis with a mitral insufficiency was diagnosed in 46 cases (20.6%) from the 223. Only 14 patients were asymptomatic, most of them having heart failure (namely, 178 patients i.e. 78%) with or without angine pectoris or effort vertigo, or they had only effort angina, vertigo or effort sincope. Rhythm disorders happened in 59 patients (26.4%) while disorders in the transmission of the stimuli were diagnosed in 14 patients (5.2%). Two patients died due to cardiac causes. CONCLUSION: Rheumatismal valve disease are nearly 2.5 times more frequent than degenerative valve disease and they became a practical reality, which is claimed by its continuously increasing frequency, by a variety of lesional aspects and by implications on the heart, and by it, presence in an age group were arteriosclerosis cumulates its risk factors.

Statistical epidemiological screening methods assessing certain biochemical markers.

The epidemiological studies have shown that it is difficult to define a "normal" value for the serum concentration of some biochemical markers with predictive significance for cardiovascular diseases (CVDs) as follows: total cholesterol (TC), total lipids (TL), triglycerides (TG), glycemia (G), and urea (U). Our study establishes the mean and limit values of the normality for the above mentioned markers, in an adult population from the Iaşi City, using the epidemiological screening method. The employed methodology includes the records of the results of 2788 biochemical determinations during a period of 5 years, in order to assess the state of health of the population, as well the data working up and interpretation by means of the EpiInfo computer program. By testing a series of "normal" limits, the values found with apparent healthy persons (n = 2691) and persons previously diagnosed with diabetes mellitus or CVDs (n = 97) were analyzed in a differentiated way. In the sample of apparent healthy individuals, with the age between 20 and up to 60, the mean values were: 210 mg% for TC; 6.74 g@1000--TL; 125.74 mg%--TG; 0.91 g%--G and 0.34 g%--U. Satisfactory correlations (correlation coefficient-"r") of age with the values of TC (r = 0.38); TG (r = 0.26) and G (r = 0.23) comparatively with U (r = 0.15) or TL (r = 0.14) were noticed. The comparison of the mean values between males and females did not reveal a significant difference (p > 0.05) for any of the assessed constants. The clinical and community studies of the CVD risk assessed in the Iaşi City area will have to be referred to the registered and analyzed values of this epidemiological screening in the interpretation of some biochemical markers data.

[Cardio-thoracic index: marker of the clinical course of alcoholic dilated cardiomyopathy].

Alcoholic cardiomyopathy (ACM), a principal form of secondary dilated cardiomyopathy, can ensue from heavy consumption of alcohol over a long period of time. In harmful consumption, alcohol and its metabolites has a toxic effect on heart muscle cells. The clinical features include dilatation of the left ventricle, poor myocardial contractility and symptoms of heart failure. The heart and lung X-ray examination is required in all disease stages. The information gathered from this cheap and noninvasive investigation method, are very important in the diagnosis algorithm. In the ACM stages beginning, before the installation of the heart failure symptoms, it is possible to found normal dimensions of the heart, which is compatible with the alcoholic cardiomyopathy diagnosis. Specific for dilated alcoholic cardiomyopathy is the reversible character of cardiomegaly, objectified through the reduction of the cardio-thoracic index in conditions of alcohol abstinence and adequate treatment of the heart failure.

[Comparing population means using the ANOVA method].

ANOVA is the abbreviation of the ANalysis Of Variance. It was developed for inferences concerning more than two populations. The tested hypothesis is the equality of the means of several normal populations. Some mathematical aspects are presented and also advantages and drawbacks of the method are marked out. Finally a practical example (implementing the ANOVA test) using the SPSS statistical software and also Microsoft Excel are shown.

[Implications of some risk factors in degenerative valvular heart diseases].

UNLABELLED: A retrospective study on 223 patients diagnosed with degenerative heart valvular lesions: 124 women with an average of 74.9 years old and 99 men with an average of 70.1 years old with the lower limit under 50 years old (one woman and one man) and upper limit over 80 years old (22 women and 11 men) revealed that 109 patients (48.8%) had arterial hypertension, 30 patients (13.4%) had diabetes mellitus, and 16 patients (7%) had obesity. Chronic alcoholism was present at 89 patients (39.9%), chronic tobacco consumption at 54 patients (24.2%), cholesterol value over 200mg/dl in 99 patients (44%) and triglycerides value over 150 mg/dl in 15 patients (6.6%). In the 15 patients with a sever form of aortic stenosis was discovered cholesterol value over 200 mg/dl as well as chronic tobacco use and alcoholism. CONCLUSION: Degenerative heart valvular disease represents a different process from arteriosclerosis, therefore the conventional risk factors of arteriosclerosis, can not be considered as having the same significance for degenerative heart diseases.

[Neurological manifestations on collagenoses].

Collagen diseases are precipitated by very different etiologic factors, but have a common pathogenic mechanism--autoimmune, which evolves chronically and progressively involving new territories. The initial and main pathologic lesions are vascular arterial ischemic (and, according to the prevalently involved territory, the type of disease results: PAN--medium-sized and small arterioles; scleroderma--small arterioles and capillaries), and the secondary ones are the result of ischemia with plurivisceral involvement. Neurological dysfunctions were detected in about 50% of collagen diseases diagnosed during a 25 year interval in the IIIrd Medical Clinic of Iaşi. The neurological manifestations were inaugural in 10% (in SLE) to 46.4% (in PAN) of the cases, the remainder occurring during the course of collagenosis, more commonly at 3-5 years and before death. Peripheral nervous system involvement (mainly polyneuritis) has prevailed, the central nervous system involvement being more rare and often fatal. Long-term corticosteroid therapy was followed by full or partial remission of peripheral nervous dysfunctions, but had transient effects or was ineffective on the central nervous ones.
