[Hypertension and obesity].

An epidemiological study was carried out in a population of men aged 35-64 years in the Bródno District of Warsaw. The study included 2123 subjects, the frequency was noted of hypertension and obesity as risk factors for ischaemic heart disease, and their correlations were studied. As hypertension the following values were accepted: --borderline hypertension = 140/90 less than 160/95 mm Hg, --stabilized hypertension = greater than or equal to 160/95 mm Hg. Overweight was accepted as Quetelet's index 29.0 weight in kg/height in cm. Stable hypertension was found in 35.0% of obese men and 18.5% of non-obese men (p less than 0.001). Borderline hypertension was demonstrated in 31.6% of obese men and 22.9% of non-obese men (p less than 0.002). Normal blood pressure was found in 58.4% of non-obese men and in only 33.4% of the obese ones (p less than 0.001). The prevalence of hypertension in obese men, both systolic and diastolic hypertension, was related to age: the highest proportion of hypertensive subjects was in the oldest group, the lowest one in the youngest group. The results agree with those reported by other authors who also demonstrated a high correlation between hypertension occurrence and increasing overweight.

[Cardiac arrhythmias in myocardial infarction as an extension of lesions to the myocardium and the state of circulatory efficiency].

The study involved 55 patients with the acute myocardial infarction aged between 34 and 69 years (mean 53 years) in whom the relation of cardiac arrhythmias incidence to the extension of myocardial involvement and circulatory efficiency was assessed. All patients were examined clinically, a 24-hour ECG with Holter technique (in the first day, 21st day and 6th months after myocardial infarction) and echocardiographic (Echo-2D) tests were registered. Echocardiography was performed during hospital phase and 6 months after myocardial infarction. Cardiac arrhythmias were evaluated with classification into classes described by Lown. Close relation of serious cardiac arrhythmias with extension of myocardial involvement was noted especially in the acute phase of myocardial infarction. High risk arrhythmias--class IVA, IVB and V were noted in nearly 100% of patients in this phase with cardiac aneurysm, extensive akinesis of apex and anterior wall of the heart. Mean value of the ejection fraction was 31% in this group. Incidence of cardiac arrhythmias did not exceed 40%, ejection fraction was 56% in the group of patients with limited lesions to the heart, e.g. akinesis of the lower wall. Incidence of late cardiac arrhythmias (6 months) did not differ significantly in particular groups of patients. The value of ejection fraction remained, however, on the same level as in the hospital phase of the myocardial infarction.
