[Clinical and angiographic predicting factors leading to unfavorable myocardial reperfusion in patients with acute ST-elevation myocardial infarction after primary percutaneous coronary intervention].

Abstract

OBJECTIVE:

To investigate the clinical and angiographic morphologic features leading to worse myocardial reperfusion in patients with acute ST-elevation myocardial infarction (STEMI) after primary percutaneous coronary intervention (PCI).

METHODS:

Clinical and angiographic data were collected and logistic regression analysis performed in 964 STEMI patients undergoing primary PCI.

RESULTS:

Logistic regression analysis showed that non-anterior myocardial infarction, pain to balloon time and degree of cardiac dysfunction were clinical predictive factors while fade-out type of angiographic morphology, ie, presence of accumulated thrombus proximal to the occlusion was angiographic predictive factor of worse reperfusion for STEMI patients post PCI.

CONCLUSION:

These predictive clinical and angiographic morphologic factors in STEMI patients for worse myocardial reperfusion post PCI could help to identify patients at high risk post PCI.
