    Streszczenie angielskie: Background. A decrease in mortality after myocardial infarction (MI) may be achieved by the improvement in risk stratification and implementation of more effective therapy. Heart rate (HR) calculated from a standard 12-lead ECG in a simple and widely accessible parameter which may be used for the assessment of prognosis after MI. Aim. To assess the prognostic value of HR derived from a 12-lead ECG recorded after the acute phase of MI and to formulate a prognostic index consisting of simple clinical and ECG parameters. Methods. The study group consisted of 309 consecutive patients (95 females, mean age 61.7 ń 12.8 years), who survived the first 48 hours of acute MI. HR derived from a 12-lead ECG recorded between 3 and 5 days after the onset of MI and other parameters were used to assess the risk of cardiac death during the one-year follow-up period. Results. During one year of follow-up, 72 (23.3 p.c.) patients died dut to cardac causes. The mean HR was significantly higher in patients who died than in survivors (89.8 ń 29.5 versus 66.2 ń 12 beats/min, p 0.0001). The multivariate analysis revealed that HR, age, Kilip class and contraindications to beta blockers were the independent parameters of prognostic significance. The prognostic index consisting of HR 75 beats/min, age 60 years, Kilip class 1 and lack of beta-blocker therapy identified patients at risk of cardiac death with a sensitivity of 75 p.c. and specificity of 100 p.c. Conclusons. HR derived from a standard ECG recorded outside the acute phase of MI is higher in patients at risk of cardiac death after MI than in survivors. HR and other clinical as well as demographic parameters provide a simple prognostic index after MI.
