It has been said that ventricular aneurysm is formed in the relatively late stage after the onset of acute myocardial infarction. We examined the time of its formation using digital subtraction angiography (DSA) performed immediately after infarction and at various intervals thereafter. We also examined correlations between aneurysm formation and the degree of rest after infarction, blood pressures, sites of infarction and coronary angiographic findings. The subjects consisted of 35 hospitalized patients with acute myocardial infarction. They were examined by DSA immediately, and one week and one month after their admissions. DSA was performed in the 30 degree right anterior oblique projection, and cardiac aneurysms were diagnosed by the presence of regional protrusion or of dyskinesis of the left ventricular wall on left ventriculography. The results were as follows: Cardiac aneurysms were noted in eight men and four women. The mean age was 69.2 +/- 8.1 years. Infarctions were located in the anteroseptal region (nine patients), in the broad anterior wall (two patients) and in the inferior wall (one patient). The average onset-to-admission interval was 5.6 hours in the aneurysm group, and eight hours in the aneurysm-free group. Cardiac aneurysms were demonstrated by DSA immediately after hospital admission in all 12 patients in the aneurysm group and the size did not increase appreciably with time. The peak CPK was significantly higher in the aneurysm group (3,163) than in the aneurysm-free group (1,655), but there was no group-related difference in risk factors, hypertension, the duration of rest after infarction, or coronary angiographic manifestations. Cardiac aneurysm has been considered as a late complication of myocardial infarction. Many investigators have reported that its formation begins one to four weeks after the onset of infarction with gradual protrusion. In the present study, however, the formation of aneurysms was complete at very early stages after the onset of the myocardial infarction and often encountered in patients with relatively extensive infarction.

The authors suggest that the males under 60 with myocardial infarction who have no chronic circulatory insufficiency in their case history should be divided into the groups of high and low risk of the development of ventricular fibrillation, thromboembolic complications and acute cardiac aneurysm. The group of risk is determined on the basis of 5 clinical characteristics: the character of myocardial infarction, the stage of arterial hypertension, evaluation of the general state, heart failure and the heart rate.

Specific features of acute myocardial infarction (AMI) onset and course, short-term outcome and its causative factors have been analysed for women and men by the data from Register of Acute Myocardial Infarction of the city of Tomsk for 1994-1998 (a total of 3717 cases). It is shown that AMI men die largely of cardiogenic shock (CS), congestive heart disease (CHD) and cardiac arrhythmia. Death of AMI women was caused primarily by CS, CHD and rupture of the myocardium. For women the unfavourable factors for an AMI outcome were the following: an atypical clinical presentation, a symptomless preinfarction period, prior AMI, arterial hypertension, diabetes mellitus, a complicated course, extensive and transmural lesion, acute cardiac aneurysm. For men the additional to these are previous angina and brain stroke. The short-term AMI outcome in women is more unfavourable than in men.

The aim of the work was to identify risk factors of atrial fibrillation (AF) in 151 patients with metabolic syndrome (MS, IDF 2005); 88 of them presented with the recurrent form of AE 63 had no arrhythmia. Practically all patients suffered from arterial hypertension. The groups were comparable in terms of age, concomitant disorders, AH duration, arterial pressure, and severity of chronic heart failure. Patients with permanent AF, hemodynamically significant heart disease, myocardial infarction with wave Q in the medical history, and cardiac aneurysm were excluded from the study. We evaluated anthropometric parameters, carbohydrate and lipid metabolism, daily albuminuria, results of echoCG, and insulin resistance. Patients with AF had worse anthropometric and metabolic parameters and more pronounced remodeling of myocardium with left ventricular diastolic dysfunction, insulin resistance, endothelial dysfunction, and renal lesions than patients with MS without AF Patients with MS having abdominal obesity and AH over 10 years, marked insulin resistance (IR index higher than 2.77), reduced HDL cholesterol level (below 1.1 mmol/l), left atrial dilation (end diastolic size >43mm), albuminuria >60 mg/d, waist circumference >104 cm were at high risk of AF (prognostically unfavourable arrhythmia). It is concluded that dynamic observation of the above MS and echo-CG parameters, and albuminuria coupled to the adequate correction of insulin resistance, control of AH and dyslipidemia is important for the prevention of cardiac arrhythmia.
