[Coronary circulation and left ventricular function in patients with transmural myocardial infarct].
Hemodynamics and left-ventricular segmental contractility were examined in 72 patients, subjected to selective coronarography and ventriculography. Forty-six patients had a history of anterior, and 26, posterior, transmural myocardial infarction (MI). Atherosclerotic stenosis of coronary arteries (more than 75% of vascular diameter) was revealed in 67 of 72 patients. Residual occlusion was shown to occur more commonly in the right coronary artery. Collateral flow was more commonly associated with a history of myocardial infarction affecting the posterior wall of the left ventricle, while segmental contractility disorders, even aneurysms, and generalized disturbance of left-ventricular contractility, as manifested in reduced mean rate of myocardial circular fibre shortening, were more typical for the affection of the anterior wall of the left ventricle.
