IN HOSPITAL MORTALITY PREDICTORS OF PATIENTS WHO UNDERGO PRIMARY PERCUTANEOUS CORONARY INTERVENTION FOR ST SEGMENT ELEVATED MYOCARDIAL INFARCTION
Objective: To assess the in hospital mortality predictors of patients whounderwent primary PCI in our hospital and to compare the results with similarstudies in the literature.
Methodology: This cross-sectional study included patients who underwentprimary PCI with the diagnosis of STEMI in department of cardiology EtimesgutGovernment Hospital, Ankara. Patients who survived and patients who diedduring their follow up in the hospital after primary PCI were assigned into 2groups. Clinical and angiographic characteristics were compared between twogroups. All statistical analyses were conducted using SPSS version 17.0 results wereconsidered as significant if the p value was <0.05.
Results: Total of 85 patients were included. To groups were made on the basesof mortality. Group one had 58 patients who survived while group two had 25patients who died during followup. Time interval between hospital admission andwire crossing (Door to balloon time) didn't differ among two groups(88,64±32,47 versus 86,72±38,33, p>0.05) where as the patients who diedhad a longer symptom onset to hospital admission time (8,72 ± 7,68 versus3,19±2,82, p=0.001). PCI performed during off hours wasn't found to berelated with increased mortality (p=0.830).
Conclusion: Because the implementation of primary PCI in our hospital fulfil thequality of care and performance indicators recommended in the guidelinesthroughout the whole day, patient related factors become more likely to beassociated with in hospital mortality compared to PCI related factors. Additionaldecline in the mortality rate can be achieved by raising the conciousness ofcommunity and improving transfer policies that could minimize the patient relatedfactors including prehospital delay.
