| Popis: | Introduction and objective. In recent years, the relation between biological markers of inflammation and prognosis in patients suffering from acute coronary syndromes has been investigated. The aim of this study was to evaluate the association between baseline fibrinogen concentrations and the development of clinical events in patients admitted with suspicion of unstable angina and non-Q-wave myocardial infarction. Material and method. Levels of fibrinogen at enrollment were analyzed in 325 consecutive patients with acute coronary syndromes. Fibrinogen values were divided into tertiles and the incidence of clinical events was evaluated at each level. The combination of death and/or myocardial infarction was the main endpoint. Results. Fibrinogen levels were significantly higher in patients who subsequently had myocardial infarction, cardiac death, or both during follow up. The probabilities of death and/or myocardial infarction were 6%, 13%, and 29% (p < 0.0001), respectively, in patients grouped by fibrinogen tertiles (304, 305-374 and 375 mg/dl). Multivariate predictors of combined events were age, previous angina, ST-segment depression in the admission ECG, and fibrinogen into tertiles. The adjusted hazard ratio (95% CI) for patients in the upper tertile was 4.8 (1.614; p = 0.004). Conclusions. High fibrinogen levels were related to a less favorable long-term or short-term outcome in patients admitted for suspicion of unstable angina and non-Qwave myocardial infarction. This association persists after adjustment for other classical risk factors such as age, prior angina, and ST-segment depression in the ECG. |
