Characteristics of late post-infarction cardiac remodeling

Abstract

The article presents the results of echocardiography in assessing cardiac remodeling in 79 patients 12 months after acute myocardial infarction (MI). 42 (53.2%) patients had Q-positive (Q+), 37(46.8%) Q-negative (Q-) myocardial infarction. After 12 months, chronic heart failure (ChHF) was detected in 32 patients, of which 23 (54.8%) as a result of Q(+), and 9 (24.3%) Q(-) infarction. In patients who underwent Q (+) MI with ChHF in the late post-infarction period, the values of left ventricular end-diastolic dimension (EDD), end-sistolic dimension (ESD), left atrial dimension (LAD), local contractility index (LCI), sphericity index (SI), left ventricular myocardial mass index (LV MMI, g/m2 ) were significantly (P<0.05, P<0.01) higher than in patients with Q ( -) MI and without ChHF. The average value of such EchoCG parameters as ejection fraction (EF, %), degree of shortening of the anteroposterior dimension of the left ventricle (ΔS, %) and the ratio of the total wall thickness and LV EDD (2H/D index) in patients with Q (-) MI was higher than in the group of patients with Q (+) and without ChHF.
