[Evaluation of left ventricular function in ischemic heart disease by systolic phase structure and echocardiographic indices].

The article describes poly- and echocardiographic examination of the ejection fraction, the mean contraction rate of the perimetric fiber of the left ventricle, the total tension period, the period of left ventricular ejection, and the tension period to ejection period ratio. The results obtained in a group of 17 healthy individuals were compared with the findings in patients with angina pectoris who were divided into 2 groups, one without any serious changes in the coronarogram (19) and the other with pathological changes in the coronary arteries (18). In patients with an abnormal coronarogram, the ejection fraction, the rate of contraction of the perimetric fiber, and the ejection period were considerably reduced. These values showed no significant changes in patients with a normal coronarogram. The ECG data correlated well with the systolic phase structure.

Calcific coronary embolization associated with cardiac valve replacement. Necropsy x-ray study.

The hearts of 14 patients dying early after replacement of a calcified aortic or mitral valve were examined for the presence of calcific coronary emboli. The incidence of embolization as shown by x-ray film was 92-9 per cent. The number of emboli in individual cases ranged from 4 to 119. Replacement of an aortic valve was associated with a more severe embolization than replacement of a mitral valve. Th mechanisms of calcific embolization are discussed and preventive surgical measures suggested.
