According to the American Heart Association, cardiovascular diseases are the main cause of death worldwide in 2015 [1]. A common consequence of coronary heart disease is acute coronary syndrome (ACS),which includes ST elevation myocardial infarction, Non ST elevation myocardial infarction and unstable angina [2]. ACS causes more than 2.5 million hospitalizations in the world every year [3].In Palestine, myocardial infarction and ischemic heart disease are the leading cause of death according to the Palestinian health information center. During 2012, twenty percent of the reported deaths among age Group 20 - 59 years were due to myocardial infarction and ischemic heart disease. In the Palestinian older age group, more than 60 years, mortality due to cardiovascular diseases was 19.4% of the overall mortality causes (Palestinian Ministry Of Health/2012) Management of ACS includes both conservative and invasive methods; the earlier consists of medical management, which can be followed by catheterization and revascularization if ischemia persists despite medical therapy. The Invasive method; that's cardiac catheterization, done within 4 to 24 hours after admission, followed by revascularization using percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) [4].The number of PCI procedure performed has been dramatically increasing during the last years in Palestine, this rapid growth in PCI as an alternative to medical therapy or coronary artery bypass graft (CABG) surgery is mainly due to PCI being less invasive and less expensive choice. Factors affect the outcome and the prognosis of PCI including age, gender, hypertension, diabetes, Creatine kinase (CK) [5].Through our research, we found insufficient data among the Palestinian population regarding PCI. We conducted this prospective study to describe patients' characteristics and their outcome in Palestine. The objectives of our study was to assess the relationship between the prognosis of primary PCI procedure and demographic factors, medical history , lab results and PCI data and to follow up each patient readmission due to cardiovascular events “including stroke, revascularization procedures, heart failure and chest pain” using the medical records within 30 days.
