Prognostic risk markers at 180 days in patients with ischemic heart syndrome without ST elevation

Background

For identification of cardiac prognostic risk markers in the emergency room, in patients with ischemic heart syndrome without ST elevation, it is important to choose the best and most cost-effective therapeutic strategy.

Aim

Evaluation of clinic, laboratorial and eletrocardiographic prognostic markers in nonselected patients with acute ischemic syndrome without ST elevation admitted to the emergency room.

Methods

A prospective study took place from June 1998 to March 2000, with 124 patients with acute ischemic syndrome without ST elevation admitted to the emergency room of a tertiary hospital. Most patients were male (58%), with an age average of 68.9 ± 12.3 years; 62.9% have had previous coronary heart disease.

Results

Left ventricular heart failure was the most important prognostic risk factor for events, with a relative risk of 3.16 (95% confidence interval, 2.28–4.04). Troponin did not indicate risk, with a relative risk of 2.14 (95% confidence interval, 0.95–3.32).

Conclusion

Left ventricular heart failure was the best risk marker of events in this population, which was older and had a higher incidence of previous coronary disease than the average.
