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.
