Effect of primary coronary angioplasty on left ventricular function and myocardial perfusion as determined by Tc-99m sestamibi scintigraphy

Abstract

Twenty-foul consecutive patients undergoing primary angioplasty were systematically studied with technetium-99m sestamibi myocardial scanning before intervention at 72 hours and at 3 months. Treatment with primary angioplasty was associated with a significant early decrease in the perfusion defect size, followed by a later improvement in left ventricular dimensions and ejection fraction.
