[Lesions of the coronary bed in patients with ischemic heart disease and ECG changes at rest].

The data of ECG at rest and of coronary angiography have been analyzed in 184 patients. Correlations between various ECG changes and the coronary bed involvement have been revealed. The authors have calculated the sensitivities and specificities of some ECG symptoms for the prediction of an atherosclerotic involvement of the coronary arteries. A sufficiently high specificity of ECG examination (89.1%) makes it useful for active detection of coronary patients, whereas its low specificity (54.2%) necessitates employment of supplementary methods of investigation.

[Relationship between myocardial contractility and collateral circulation in patients with ischemic heart disease].

By analyzing coronary angiograms and ventriculograms of 61 patients with the narrowed lumen of one or several coronary vessels by 90-100%, the dependence of the contractile function of the myocardium on the development of the collateral circulation in the cardiac muscle was studied. The assessment of the segmentary contractility of the left ventricle served as a criterion of the efficiency of the collateral circulation. The segmentary contractility was shown to be dependent on the presence or absence of the collateral circulation and also on the number of damaged vessels. The collateral circulation was also demonstrated to contribute to the maintenance of the contractile function of the myocardium.

[Intravenous digital subtraction ventriculography: technical and methodologic aspects, a comparison with cineventriculography].

Intravenous digital subtraction ventriculography (IDSV) was performed in 294 patients with various pathology. The IDSV method and conditions for obtaining informative ventriculograms were described. Hemodynamic indices and LV segmental contractility were assessed. IDSV and CVG data were compared in 52 cases. The results of both methods showed high correlation, IDSV having advantages over CVG (the absence of a cardiosuppressive effect resulting from direct administration of a contrast medium into the LV chamber and excluding LV quantitative overload). IDSV as a semiinvasive and easy-to-perform method has no contraindications.
