INTRODUCTION AND OBJECTIVES: The benefit of manual thrombus aspiration (TA) in the reperfusion of patients with ST-elevation myocardial infarction (STEMI) has been hotly debated. In most series, failure of TA has been largely unreported. Our objectives were to assess the rate, predictors, and impact on cumulative mortality of failed TA during primary percutaneous coronary intervention (PPCI).
METHODS: This was a single-center, retrospective study of consecutive STEMI patients undergoing PPCI with TA. TA was considered ineffective if, before angioplasty, coronary flow was TIMI <2. Independent predictors of TA failure were assessed by logistic regression, and predictors of cumulative mortality were assessed by Cox regression analysis.
RESULTS: Of 574 patients, TA was used in 417 (72.6%), and was effective in 365 (87.5%) and ineffective in 52 (12.5%). On multivariate analysis, SYNTAX score (OR=1.049, 95% CI: 1.015-1.084, p=0.005) and total ischemic time (OR=1.001, 95% CI: 1.000-1.003, p=0.02) were independent predictors of TA failure. Moderate or severe left ventricular dysfunction (HR=6.256, 95% CI: 1.896-20.644, p=0.003), APPROACH score (HR=1.094, 95% CI: 1.016-1.177, p=0.017), Killip class III/IV (HR=2.953, 95% CI: 1.122-7.770, p=0.028) and creatinine clearance on admission (HR=0.973, 95% CI: 0.953-0.994, p=0.011) were independently related to cumulative mortality at 24±0.82 months.
CONCLUSIONS: Total ischemic time and SYNTAX score were independent predictors of TA failure. However, in medium-term follow-up, ineffective manual TA was not independently related to cumulative mortality.
