Abstract: The aim of our study was twofold: initially to investigate the effects of the informative value of the variables of the acute period on the risk of cardiovascular death during the long-term period following the first acute coronary syndrome, and then to determine the long-term survival rate in different risk groups. Methods — The prospective five-year observational study included 732 patients with acute coronary syndrome who had survived the hospital period. Employing multivariable Cox’s proportional-hazard analysis, the most informative variables were selected, the risk score index was calculated, the risk groups for the prediction of cardiovascular death were identified, long-term survival (4.5 ± 2.1 years) in different risk groups was determined and internal validation of the model was performed. Results — During the observational period, 84 patients (11.5%) died due to cardiovascular causes. Cox proportional-hazard models demonstrated that six variables had significant influence on longterm survival during the five-year period after an acute coronary syndrome. These variables were: age [1-5 points], the presence of pathologic Q wave in > 2 ECG leads [2 points], Killip class II-IV [2-4 points], left ventricular ejection fraction 10 points - 23.3%]. The probability of survival within the period of five years was found to be favourable for the majority of patients in the low- and medium-risk groups, while the number of such patients in the high-risk group was significantly lower [97.0% vs. 89.0% vs. 73.0%, P < 0.0000]. The difference in the survival probability was negligible in developmental and validation sets [...]
