ABSTRACT
The systolic time intervals were determined on a daily basis in 17 patients with an acute transmural myocardial infarct. The left ventricular ejection time, the Q-S2 interval and their respective indices diminished, reaching its maximum shortening on the third day. The isometric contraction time, the pre-ejection period and the ratio of the PEP/LVET lengthened from its initial level reaching its maximum about the third day. By the fifth day the systolic time intervals were returning back to the values obtained on the first day. This study indicates that the PEP and LVET can adequately reflect left ventricular performance in patients with an acute myocardial infarction. These external measurements may be used to follow progression of myocardial dysfunction.

    Background and Objectives: Some recent data indicate that risk of death after acute coronary syndrome is under genetic control. Previously, we found that the C4B*Q0 genotype (low copy number of the C4B gene that encodes the fourth component of complement) is strongly associated with morbidity...

    Background: In patients with acute myocardial infarction, estimation of infarct size by cumulative lactate dehydrogenase release at 72 h (LDHQ72) is a simple and widely used method. Our objective was to study the value of estimating infarct size, by the cumulative release of LDH over 72, 60, 48...
