The Correlation between Left Ventricular Ejection Fraction and Peripheral Blood MCP-1 NT-Pro BNP in Patients with Acute Coronary Syndrome

Background: To analyse the correlation between left ventricular ejection fraction and Peripheral blood MCP-1 NT-pro BNP in patients with acute coronary syndrome. Hypothesis: The relationship between MCP-1 and NT-pro BNP. Methods: Peripheral blood MCP-1 NT-pro BNP were examined in 89 patients with acute coronary syndrome, measured LVEF by Color Doppler ultrasound. The patients were divided into three groups according to LVEF and were analysed the correlation: group A composed of 28 patients with LVEF ≤ 40%, group B composed of 31 patients with LVEF between 41% and 55%, group C composed of 30 patients with LVEF>55%. The patients were further divided according to type of ACS patients with acute myocardial infarction (AMI) group and unstable angina (UA) group, comparing the index differences. Results: Peripheral MCP-1, NT-pro BNP levels tend to increase gradually (C group
