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