Abstract :Objective: Coronary slow flow insert ignore into journalissuearticles values(CSF); is known as a form or early stage of common atherosclerotic disease. Myocardial perfusion scintigraphy insert ignore into journalissuearticles values(MPS); is a valuable technique in the diagnosis of coronary artery disease and prediction of prognosis. The aim of this study was to investigate the relationship between the myocardial defect score and ischaemia in patients with CSF. Methods: A total of 168 patients who applied with the complaint of angina pectoris and underwent SPECT as a non-invasive test followed by coronary angiography were included in this retrospective study. 9 patient was excluded from the study for various reasons. The study population comprised determined with CSF and no obstructive stricture in the coronary arteries and with normal flow. The mean age of the patients was 56±12 years. The scores obtained from Quantitative Perfusion SPECT insert ignore into journalissuearticles values(QPS); and Quantitative Gated SPECT insert ignore into journalissuearticles values(QGS); software were used in the myocardial perfusion evaluation. The TIMI frame counts were compared with the myocardial defect and ischaemia scores. The TIMI frame count method was used in the determination of CSF. Results: In patients with slow flow in the circumflex insert ignore into journalissuearticles values(Cx); coronary artery, the stress total perfusion defect Cx insert ignore into journalissuearticles values(sTPD-Cx); was found to be 0.1 insert ignore into journalissuearticles values(range, 0.0-1.3);, and in those with normal flow, it was 0.0 insert ignore into journalissuearticles values(range, 0.0-0.28); insert ignore into journalissuearticles values(p=0.002);. The stress score Cx insert ignore into journalissuearticles values(sscore-Cx); was found to be 1.0 insert ignore into journalissuearticles values(range, 0.0-3.0); in patients with slow flow and 0.0 insert ignore into journalissuearticles values(range, 0.0-2.0); in those with normal flow insert ignore into journalissuearticles values(p=0.031);. A linear correlation was determined between the Cx TIMI frame count and the sTPD-Cx and sscore-Cx values insert ignore into journalissuearticles values(r=0.207, p=0.009; r=0.159, p=0.045);. No relationship was found between slow flow and the defect and ischemia scores in other myocardial regions. Conclusion: In patients with slow flow in the Cx coronary artery, the sTPD-Cx and the sscore-Cx values were found to be significantly high. Although at a weak level, a linear correlation was found between the Cx TIMI frame count and the sTPD-Cx and the sscore-Cx values
