Haematological Indices And Clinical Factors Predicting The Coronary Slow Flow Phenomenon In Coronary Angiography

Background: Coronary slow-flow phenomenon (CSFP) is an enigmatic entity. Its multifactorial pathophysiology is less well understood. Objective: To evaluate clinical and haematological parameters predicting the CSFP. Methods: We accessed the hospital records of the patients undergoing coronary angiography from May 2019-December 2019. The patients with CSFP were compared with the patients having normal epicardial coronary arteries (NECA). Results: The prevalence of CSFP was 2.9% in this study. CSFP patients had male dominance (72.3%). Body mass index (BMI), and haematological parameters such as haemoglobin, neutrophil-lymphocyte ratio, haematocrit, platelet count, mean platelet volume, and plateletcrit (PCT) were significantly higher in CSFP group compared to NECA group. On multivariate logistic regression analysis, high PCT [odds ratio:15.8; 95% CI(3.5-70.1), p
