Doppler echocardiographic study of right ventricular systolic performance in inferior myocardial infarction.
Twenty-four male patients with myocardial infarction (MI) without clinical and electrocardiographic signs of right ventricular (RV) involvement were selected to enter the study. All the patients were divided into two groups: Group I consisted of 12 patients with anterior MI and infarct-related left anterior descending artery and Group II included 12 patients with inferior MI and infarct-related right coronary artery. Patients of Group II had higher right atrial pressure and right atrial pressure/pulmonary capillary wedge pressure ratio (p<0.01, p<0.01) and lower values of pulmonary flow velocity, mean acceleration, and pulmonary flow velocity2/acceleration time ratio than patients of Group I (p<0.01, p<0.01, p<0.01, respectively). Pulmonary flow indices correlated inversely and significantly with hemodynamic dysfunction in patients with inferior myocardial infarction and right coronary proximal lesions (p<0.01).
