Evaluation of the Correlation Between Myocardial Perfusion Scan Findings and Invasive Coronary Angiography Results

Abstract

Background: Non-invasive and cost effective treatments of coronary artery disease (CAD) are a health priority and a current necessity. Objectives: This study aimed at comparing the results of myocardial perfusion imaging (MPI) with coronary angiography findings in the diagnosis of CAD. Methods: This cross sectional study included 155 patients with stable angina, who were referred to Kowsar hospital, Semnan, Iran, from May 2013 to April 2014. After confirmation of positive perfusion imaging, angiography was performed within 3 months. Myocardial perfusion imaging results were categorized as mild, moderate and severe, and also in coronary angiography, narrowing of more than 50% of the vessels was considered as significant stenosis.
