[Structural and functional changes of the myocardium after coronary artery bypass surgery in patients with postinfarction left ventricular remodeling].
In patients with left ventricular end diastolic dimensions >5--< or =5.5 cm myocardial revascularization was associated with significant decreases of diastolic and systolic left ventricular dimensions in immediate postoperative period. This adaptational phenomenon was called passive reducing left ventricular remodeling. In patients with left ventricular end diastolic dimensions <5 and >5.5 cm revascularization was associated with dilation of the left ventricle. Restoration of myocardial blood supply produced overall positive effect on left ventricular functional capacity in patients with various severity of its postinfarction remodeling. Pathways of realization of this positive effect could be different.
