Abstract
Background: Primary Coronary slow flow (PCSF) was identified as an exclusive clinical entity in 1972(1).where the distal opacification of the coronary artery is delayed on angiography in the absence of significant obstructive coronary artery disease. It was reported that the incidence of PCSF was 1{u2013}7% in patients who underwent coronary angiography for suspicion of coronary heart disease. Aim of the Work: To determine the predictors of primary coronary slow flow, to investigate the possible association between inflammatory markers as (neutrophil to lymphocyte ratio, platelets to lymphocyte ratio , lymphocyte to monocyte ratio and high sensitive C-reactive protein)and Primary coronary slow flow judged by angiography in patient with chronic stable angina Patient and methods: We conducted a case-control study including all patients referred for coronary angiography for stable CAD, using two groups: 30 patients with PCSF and 30 patients with normal coronary angiography. The study was done in National Heart Institute{u2019}s catheterization laboratories during the period from December 2017 to December 2018, All patients were subjected to signing a written consent, thorough history and physical examination, Laboratory parameters including Platelets to lymphocyte ratio (PLR), Neutrophil to lymphocyte ratio (NLR), Lymphocyte to Monocyte ratio (LMR), and HsCRP. All patients underwent 12-lead-ECG, Echo data were assessed regarding the left ventricular dimensions and functions and regarding coronary angiography; Coronary blood flow was measured quantitatively using the TIMI frame count
