Predictors in no-reflow phenomenon in acute myocardial infarction with ST-segment elevation.

BACKGROUND
No-reflow (NR) phenomenon is one of the most feared complications after percutaneous coronary intervention (PCI) in the treatment of ST-segment elevation myocardial infarction (STEMI) due to its high morbidity and mortality.


OBJECTIVE
To describe the predictive factors for NR phenomenon in a group of subjects with STEMI treated with PCI.


METHOD
One hundred and three cases of STEMI who underwent PCI. The subjects were divided according to the presence of NR phenomenon. In a multivariate analysis age, gender, comorbidities, weight, and other clinical and laboratory parameters were studied as predictors of NR phenomenon were studied.


RESULTS
In this study, logistic regression analysis identified as independent factors for the development of NR phenomenon baseline TIMI flow ≤ 2 (OR 6.03; 95% CI, 0.9 to 11.8; p = 0.04), ER KDIGO ≥ 3 (OR OR 2.61; 95% CI, 1.0 to 2.4; p = 0.04).


CONCLUSIONS
NR phenomenon continues to be a challenge for short and long-term morbidity and mortality in STEMI. The identified factors can be used for the stratification of cases with STEMI and risk of NR phenomenon prior to PCI.
