Prognostic factors of the patients admitted to the hospital at the subacut period of STEMI

Background: Acute myokardial infarction (AMI) is a common disease that causes severe morbidity and mortality. Assesment of risk stratification at admission is important for deciding whether medical or interventional therapy is better. The most important step of the STEMI treatment is rapid reperfusion of arteries and it is shown in many studies that, sooner you get reperfusion more you get alive myocardial tissue. But it?s not clear whether percutaneus coronary intervention (PCI) is better for the patients who applied to hospital at subacute period and not have any clinic and/or electrocardiographic evidence for continued ischemia when more than 12 hours passed from onset of the symptoms. We aimed to determine the factors that may be responsible for morbidity and mortality at the time of admission and also interventional or medical treatment options in the patients who applied to hospital at subacute period after beginning of the STEMI concordant symptoms.Methods: 94 patients with subacute STEMI were included in this study. (62 male, 32 female) Their follow-up time is 29±27 months. The patients?, who died or lived and who had or not have major adverse cardiovascular events during in-hospital and out hospital follow up time, clinic and biochemical values were compared to each other.Results: Age, Killip score, ST elevation amount on admission ECG, creatinin and MPV values of the patients who died, were significantly higher than the patients who lived and their ejection fraction, hematocrit values were significantly lower. Also history of congestive cardiac failure, atrial fibrillation on ECG at admission and large QRS existance were significantly much more than the patients who survive. Killip score, age and creatinin were determined by logistics regression analysis to be significant mortality marker in the patients who died during in hospital follow up time. Major adverse cardiovascular events and death rate were found lower in the patients who underwent PCI during follow up time.Conclusions: Determination of the factors that may be responsible for morbidity and mortality at the time of admission in the patients who admitted to hospital at subacute period after beginning of the STEMI concordant symptoms, can help us to predict patients? in hospital and life time prognosis and to decide the most suitable therapy for the patients. Late percutaneus coronary intervention (PCI) may reduce major adverse cardiovascular events and death rate in the patients who not have any clinic and/or electrocardiographic evidence for continued ischemia.
