Prediction of short-term mortality after primary percutaneous coronary intervention for acute ST-elevation myocardial infarction

ObjectiveThe aim of this work was to predict short-term mortality after a primary percutaneous coronary intervention (PCI) for patients with ST-elevation myocardial infarction (STEMI) in terms of demographic, clinical, echocardiographic, and coronary angiographic data.BackgroundAccurate risk stratification after primary PCI is important as mortality in STEMI patients represents a considerable number of all causes of mortality.Patients and methodsThis registry included 50 patients who presented to the emergency department at Nasr City Health Insurance Hospital in Cairo during the period from September 2012 to June 2013 and were diagnosed with STEMI. Every patient underwent demographic, clinical, echocardiographic, and angiographic assessments for risk factors leading to mortality in hospital and after 6 months of follow-up.ResultsEight variables were identified in our registry as predictors of short-term mortality after primary PCI including age (P = 0.005), increased serum creatinine (P = 0.010), KILLIP class (P < 0.001), left ventricular ejection fraction less than 40% (P = 0.021), multivessel disease (P = 0.018), type of culprit vessel (P < 0.001), postprocedural TIMI flow (P < 0.001), and postprocedural myocardial blush (P < 0.001).ConclusionIn acute myocardial infarction patients treated with primary PCI, eight risk factors were identified. These factors predict short-term mortality accurately.
