Simple risk index- a prognostic tool for patients with ST-elevation myocardial infarction treated with primary percutaneous intervention
Journal Title: Polski Przegląd Kardiologiczny - Year 2006, Vol 8, Issue 2
Abstract
Introduction: A successful risk stratification of patients with ST elevation myocardial infarction (STEMI) is one of the challenges of the modern cardiology. A simple risk index, containing information about patients' age, systolic blood pressure (SBP) and heart rate (HR) on admission, was derived from the cohort of patients with STEMI treated with fibrinolysis. It was developed for rapid in-hospital and 30-day risk assessment. Aim of study: To validate the usefulness of simple risk index in registry of STEMI patients treated with primary percutaneous intervention (pPCI) to predict 30-day and one-year mortality. Material and methods: The study comprised 465 consecutive patients with STEMI treated with pPCI (mean age 58.3± 11.35 years), who were followed-up for approximately one year (median 430 days). Simple risk index was calculated and patients were categorized into quintiles and divided into 3 riskgroups: low risk group (lstand 2nd quintile), medium risk(3rcl and 4thquintile) and high riskgroup (5th quintile). Multivariate logistic regression analysis, Kaplan-Meier survival analysis as well as ROC curves (Receiver Operating Characteristic) were used for statistical analysis. Results: The risk index values at presentation ranged from 2.7 to 65.2 (median 18.4). Patients from the high risk risk group had significantly lower 30-day and one-year survival than the individuals from medium and low-risk groups (p
