ABSTRACT
INTRODUCTION:
Left ventricular remodelling is a process of change in size, shape, wall thickness and heart function, initiated by a noxious stimulus such as ischaemia. Methods of pharmacological and surgical inhibition or reversal of remodelling are being sought.AIM:
To assess the influence of coronary artery bypass grafting on echocardiographic measures of left ventricular size and shape in medium-term follow-up.METHODS:
In a group of 30 patients three echocardiographic examinations were performed before CABG operation, 3 months after and 20 months after the operation. Left ventricular area and volumes as well as indices of sphericity, thinning and expansion were calculated.RESULTS:
After the operation, left ventricular areas measured in short axis and in apical four-chamber view increased among patients with a history of myocardial infarction. Improvement in the sphericity index occurred after the operation in patients with a history of myocardial infarction in whom the ejection fraction before the operation was less than 50%.CONCLUSIONS:
The left ventricular remodelling process progresses after coronary artery bypass grafting in patients with a history of myocardial infarction. Inhibition of remodelling may be expected in patients without myocardial infarction, with preserved left ventricular systolic function.
