Inter- and left intraventricular dyssynchrony in patients with Q-wave acute myocardial infarction

Background: Inter- and left intraventricular dyssynchrony is a frequently observed feature in patients with chronic heart failure. However, few data exist concerning the actual presence or absence of dyssynchrony in acute myocardial infarction (AMI). The goal of this study was to determine the prevalence of inter- and left intraventricular dyssynchrony in patients with AMI by different echocardiographic approaches. Methods: 91 patients were examined at the 1st day of Q-wave AMI. Interventricular dyssynchrony was established when interventricular mechanical delay estimated by pulse wave Doppler of aortic and pulm…
