Summary

Background:

A patient`s individual chance of being diagnosed with cardiovascular disease can be determined by risk scores.

Objectives:

To determine the risk score profiles of patients presenting with a first acute coronary event according to pre-admission risk factors and to evaluate its association with long-term mortality.

Methods

:

The research was based on a retrospective study of a cohort from the 2010 and 2013 Acute Coronary Syndrome Israeli Surveys (ACSIS). Inclusion criteria included first event and no history of coronary heart disease or cardiovascular disease risk equivalent. The Framingham Risk Score, the European Systematic COronary Risk Evaluation (SCORE), and the American College of Cardiology/American Heart Association/ (ACC/AHA) risk calculator were computed for each patient. The risk profile of each patients was determined by the three scores. The prognostic value of each score for 5 year survival was evaluated.

Results:

The study population comprised 1338 patients enrolled in the prospective ACSIS survey. The ACC/AHA score was the most accurate in identifying patients as high risk based on pre-admission risk factors (73% of the subjects). The Framingham algorithm identified 53%, whereas SCORE recognized only 4%. After multivariate adjustment for clinical factors at presentation, we found that no scores were independently associated with 5 year mortality following the first acute coronary event.

Conclusions:

Patients with first acute coronary event had a higher pre-admission risk scores according to the ACC/AHA risk algorithm. No risk scores were independently associated with 5 year survival after an event.
