Abstract:
Objective:To explore risk factors for no‐reflow after emergency coronary intervention in aged patients with a‐cute ST elevation myocardial infarction (STEMI) . Methods:According to presence of no -reflow (≤TIMI grade Ⅲwas considered as no-reflow) after operation or not ,a total of 700 aged STEMI patients hospitalized in our hospital during 2010-2013 were divided into no-reflow group (n=190 ,27. 14% ) and reflow group (n=510 ,72. 86% ) . Clinical data , PCI and coronary angiography data were collected ,compared and analyzed between two groups . Results:Compared with reflow group ,there were significant rise in percentages of patients with TIMI grade 0-1 (61.17% vs. 82.11% ) ,coro‐nary collateral blood flow grade 0 (64.12% vs. 74.21% ) ,5 thrombus scores before PCI (58.83% vs. 80.00% );signifi‐cant reduction in systolic blood pressure (SBP) at hospitalization [ (111.2 ± 24.6) mmHg vs. (101.7 ± 25.9) mmHg] in no-reflow group , P<0. 01 all. Multi-factor Logistic regression analysis indicated that SBP<101 mmHg at hospitaliza‐tion ,collateral blood flow grade 0 before PCI and 5 thrombus scores before PCI were risk factors for no‐reflow after emer‐gency PCI (OR=1.006~4.398 , P<0.05 or <0.01) .Conclusion:In aged acute STEMI patients ,those with risk factors for no-reflow after emergency PCI should take corresponding preventive and therapeutic measures in order to improve their prognosis .
