- W2892074904 abstract "BACKGROUND : Angina with normal epicardial coronaries occurs in upto 20% of patients who underwentcoronary angiogram for angina. Coronary slow flow comprises a separate group among this populationdesigned Syndrome Y and accounts for upto 7% of patients undergoing CAG for angina. Coronary slowflow is characterized by the delayed passage of contrast injected into the epicardial coronaries.Conventionally, coronary slow flow is determined by the coronary filling time. We tried to determinewhether coronary emptying time is a significant predictor of coronary slow flowMETHODS : We selected consecutive patients, who underwent angiogram for angina and found to havenormal epicardial coronaries, randomly between the study period November 2011 and November 2012.We assessed the coronary filling and emptying times at prespecified standard vascular landmarks on thebasis of TIMI frame countsRESULTS : We analysed the angiograms of 37 patients. 27 patients had LAD slow flow and 17 patients hadRCA slow flow (10 had normal flow in LAD and 12 had normal flow in RCA). 8 had non dominantsmall RCA and was excluded from the study. We observed positive correlation of coronary filling timesand emptying times, both in LAD and RCA, in slow flow patients unlike those with normal flow. Wefound the filling times and emptying times are significantly prolonged in slow flow patients (p value<0.05) in LAD and RCA. Capillary and venous transit time is prolonged in both LAD and RCA slowflow groups, but was significantly prolonged in RCA slow flow patients. (Pvalue <0.05, LAD slow flowgroup, P value 0.43). We observed slow flow significantly more in male population and significantlyassociated with high LDL/HDL ratios and high triglycerides.CONCLUSION : Coronary emptying time is an independent and significant predictor of Coronary Slow FlowPhenomenon." @default.
