IMPORTANCE OF CARDIAC AND PULMONARY HEMODYNAMICAL VALUES IN VARIOUS PERIODS OF MYOCARDIAL INFARCTION FOR EARLY DIAGNOSING POSTINFARCTIONAL HEART REMODELING

Abstract

We have used the method of B-mode echo to study the values of cardiac hemodynamics: end systolic and diastolic volumes and ejection fractions for left atrium and left ventricle, mean pulmonary artery pressure, as well as LV mass in 74 patients on the 3rd, 10th and 30th days since the development of a q-MI. We have divided the patients into two groups based on the localization of the lesion. Our analysis has revealed that in those with anterior MI showed a more marked chamber enlargement and function impairment for left atrium and ventricle compared to patients with inferior infarction. In the early period of MI left atrium function is improved on the background of its dilation and is one of the compensatory mechanisms targeted at decreasing pulmonary hypertension.
