Survey of effective factors in slow flow and no reflow in primary percutaneous coronary intervention patients

خلاصه انگلیسی

Background: The phenomenon of no reflow is a phenomenon that after angioplasty and the successful insertion of the stent, the blood flow rate is reduced again in the coronary arteries and there is no mechanical obstruction. The slow flow phenomenon is an angiogram that is associated with delayed progression of contrast media during coronary artery during angiography in the absence of coronary stenosis. The aim of this study was to investigate the prevalence and factors affecting these phenomenons in Primary percutaneous coronary intervention (PCI) patients. Methods: This cross-sectional study was performed. The statistical population of the patients is 340 people who were under the Primary PCI. After the patients 'data, information was collected through a questionnaire and patients' records. Results: 48 patients entered the PCI process more than 90 minutes after admission to hospital. The highest frequency is related to anterior MI and LAD was the most frequency based on type of vessel involvement, 12 of them died and 17.1% of patients had no reflow and 12.9% of patients had slow flow. The mean diameter of stents in patients was 2.98 and the mean balloon diameter in patients was 2.01 and there is a significant relation between stent diameter and balloon diameter with slow flow and no reflow (p<0.05). Conclusions: The results of this study showed that the prevalence of slow flow and no reflow after primary PCI in patients with heart attacks were at a high level with 12.9% for slow flow and 17.1% for no reflow
