[Non-invasive methods of examination in evaluation of cardiac reserve and contractile function of the myocardium in patients with postinfarct cardiac aneurysm].
Non-invasive diagnostic procedures (electrocardiography, spiroergometry, polycardiography) were compared with selective coronarography and left-side radioventriculography in 132 patients with chronic post-infarction aneurysm of the heart, in order to demonstrate their respective diagnostic values for the assessment of coronary and myocardial reserves of the heart. It was shown that physical stress tolerance, pO2max, the oxygen debt/oxygen requirement percentage ratio could be indicative of disturbed coronary reserve, while prolonged P wave and left-atrial deviation time, the number of abnormal Q and QS waves and increased resting myocardial contractility index (above 0.550) suggested impaired myocardial contractility.
