[Radionuclide ventriculography in the diagnosis of a postinfarct aneurysm and the evaluation of its impact on left ventricular function].

This is a report on thirty-four patients subjected to radionuclide ventriculography because of suspected post-infarction aneurysm. To discover eventual kinetic disorders, apart from visual assessment of the wall kinetics, amplitude-phase analysis is also employed. The sensitivity of the method is compared with that of bi-dimensional echocardiography.

[Radionuclide ventriculography for the diagnosis of postinfarct aneurysm and the assessment of its impact on left ventricular function].

Radionuclide ventriculography was performed in 34 patients suspected of having postinfarction aneurysm. In addition to visual appraisal of wall kinetics, amplitude-phase analysis was used for detecting kinetic disorders. The sensitivity of the method was compared with that of two-dimensional echography, and postinfarction left ventricular function was assessed by the two methods.

[Treatment of light and moderate arterial hypertension with acebutolol].

The authors follow up the effectiveness and tolerance of monotherapy with acebutolol in 47 patients with light and moderate hypertension, in a dose of 400-1200 mg in the course of three months. Twenty two of the patients have been treatment with the original French drug of the firm "Specia" and the rest 25--with the Bulgarian preparation, produced by Pharmachim according to a licence of the French one. The following parameters were followed up: arterial pressure, pulse rate, ECG, eventual adverse effects on 30, 60, 90 day of the treatment.

[Preoperative clinical and hemodynamic assessment of patients for surgical revascularization of the myocardium].

A group of 35 patients with ischemic heart disease (IHD) and 6 patients with aquired heart defects, with established significant coronary obstruction were studied. The clinical picture of the patients with IHD is dominated by severe, refractory to treatment angina pectoris with extensive and high-degree stenosing coronary angina pectoris in combination with a relatively preserved left ventricular function. The patients with aquired defects have no anginal complaints.

[Hemodynamic indices assessed by impedance cardiography in patients with the subacute stage of myocardial infarct before and during bicycle ergometry].

The hemodynamic indices were determined in 51 patients with myocardial infarction, subacute stage, before and after bicycle ergometric loading. The following indices were determined by impedance cardiography: cardiac output, total peripheral resistance, volume velocity of blood ejection, power of cardiac contractions, index of myocardial contractility etc. The results reveal that the patients with subacute stage of myocardial infarction have reduced reserve possibility of blood circulation apparatus.
