Clinical Analysis Of The Risk Factors Of Slow Coronary Flow

ObjectiveTo evaluate the clinical and angiographic characteristics of patients with SCF andprovide evidences for prevention.MethodsIn this retrospective study, we enrolled50consecutive patients with SCF,60patients with coronary artery disease(CAD), and50normal patients. All patients wereundergoing coronary angiography. The clinical and laboratory data were obtainedfrom medical records at admission.Resultwe found the presence of hypertension, white blood cell count(WBC),neutrophil-to-lymphocyte ratio(N/L), high density lipoprotein cholesterol(HDL-C),apolipoprotein A(APOA), electrocardiogram(ECG) changes were different betweenthe three groups(P<0.05). Compared to the control group, the WBC and N/L ratiowere significantly higher in patients in both the SCF and CAD groups(P<0.05), butthere were no significant difference between SCF group and CAD group(P=0.606,0.847). There was no significant difference in the rate of ECG ST-Tsegment changes between SCF group and CAD group(P=0.825), but they were bothsignificantly higher then control group(P=0.013,0.003). After adjusting for other riskfactors,WBC (OR=1.290,95%CI:1.032~1.614,P=0.026), HDL-C(OR=0.231,95%CI:0.058~0.922, P=0.038)were independent factor for SCF(all P<0.05). ConclusionsOur results demonstrated that patients with SCF were prone to have a significantmetabolic disorder and high levels of WBC compared to the control group; Patientswith SCF have significantly changes in ECG ST-T segment.
