Clinical and angiographic predicting factors leading to unfavorable myocardial reperfusion in patients with acute ST-elevation myocardial infarction after primary percutaneous coronary intervention / 中华心血管病杂志

ABSTRACT

<p><b>OBJECTIVE</b>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).</p><p><b>METHODS</b>Clinical and angiographic data were collected and logistic regression analysis performed in 964 STEMI patients undergoing primary PCI.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>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.</p>
