Abstract

Objectives: There are some studies on the determinants of in-hospital percutaneous coronary intervention (PCI) outcomes in Asian developing countries but none has developed a risk score. The objective of our study is to develop a simple risk score for in-hospital outcomes after PCI.

Methods: A cohort study was conducted in a medical centre in Kuala Lumpur, Malaysia from January to December 2010 where 322 patients were followed up for at least six months. In- hospital outcomes including mortality, myocardial infarction, stroke, cardiac arrhythmia, cardiogenic shock, bleeding, dissection and pseudoaneurysm were determined. Stepwise logistic regression was used to select determinants of PCI outcomes which were then weighted into a simple risk scoring system.

Results: The study cohorts were mostly Malays with male formed the majority (80%). In-hospital outcomes occurred in 22% of patients. Determinants of outcomes in the final model were cardiogenic shock, NYHA class 2 and more, anaemia and high systolic blood pressure. The area under receiver operating characteristic curve (AUC) for the model was 0.69 and 0.68 in the validation model indicating moderate discrimination ability.

Conclusion : This simple risk score has a moderate ability to discriminate patients at risk of having in- hospital outcomes after PCI in a developing Asian country
