Assessing the outcome of patients who underwent a primary percutaneous coronary intervention

Abstract

Introduction: Patients presenting with acute ST- elevation myocardial infarction (STEMI) of less than 12 hours from onset of chest pain are candidates for primary percutaneous coronary intervention (PPCI). Aim: To assess the patients’ outcome after 12 months of their admission by a retrospective observational study. Methodology: Data of patients admitted with STEMI and preceding to PPCI between 1st of January 2011 to 30th of June 2011 were analyzed. A total of 105 patients were recruited, identified and analyzed by using Cardiac Investigation and Patient Record (CIPR) software. Survival outcomes were determined by mortality data obtained from the Department of Information, Health and Research. Results: Out of the 105 patients having PPCI, the majority were men (81%). 8.6% died within one year. 20% had scheduled repeat coronary angiography, 9.5% requiring further PCI. 0.95% had target vessel revascularization while another 0.95% was referred for coronary artery bypass grafting (CABG) due to triple vessel coronary disease. Unplanned re-admissions rate due to another episode of chest pain was of 5.7%, out of which one presented with another STEMI requiring PPCI. The other patients underwent inpatient coronary angiogram, with 2 proceeding to PCI. The remaining 63% did not experience any other cardiovascular related episodes. Conclusion: This analysis showed that the re- admission rates over a year requiring further interventions were low as was the death rate. Only one target vessel revascularization was performed suggesting that the majority of the PPCI’s performed were successful. This is important when assessing the quality of cardiovascular interventional service provided by our state health system.
