Aim: To compare clinical profile, findings on urgent coronarographyc and early course in patients with STEMI at young and old age. Patients and methods: retrospective analysis of patients in 2 age groups: up to 50 yrs (group A) and over 75 yrs (group B) who underwent urgent coronarography for STEMI. History, coronarographic findings, function of left ventricle, therapy and hospital mortality were evaluated. Results: the followed - up at our work place, there were hospitalized during evaluated period of time in our department for STEMI in group A 90 pts.at the age of 26-50 (mean age 44.6) years and 87 pts. in group B at the age of 75-89 (mean 78.3) years. In the group of younger patients the ratio of males was 79 (87.7 %) vs 39 (448 %) (p < 0.001), positive family history of cardiovascular diseases was in group A in 55(61.1 %) vs 25 (28.7 %) pts., p < 0.001. Presence of hypertension was in group A in 36 (40 %) and in group B in 61 (70.1 %) pts., p < 0.001 and diabetes mellitus in 6 (6.7 %) vs 26 (29.9 %) pts., p < 0.001. In group A there were 68 (75.6 %) smokers vs 13 (14.9 %) pts. In group B (p < 0.001).Ten patients (11.1 %) in group A were after myocardial infarction, in group B 18 patients (20.7 %) pts., p=0.036 and 2 (2.2 %) vs 24 (27.6 %) pts. after stroke, p < 0.01. Lesion of 1 vessel on coronography was evaluated in 47 (52.2 %) pts. in group A vs 21 (24.1 %) in group B (p < 0.001). Average LVEF achieved 48 % in group A vs 41 % in group B (p < 0.001). 79 (87.8 %) pts. in group A and 71 (81.6 %) pts .in group B underwent direct PCI, p=ns, conservative therapy was applied in 11 (12.2 %) pts. in group A vs 16 (18.4 %) in group B, p=ns. Death during hospitalization was reported in group A in 3 pts. (3.3 %) vs 12 pts. (13.4 %) in group B (p=0.01). Conclusion: Patients with STEMI at the age over 75 years represent a risk group with significant comorbidity and frequent findings of multivascular lesions of coronary bed at initial coronarography. Compared with patients treated for STEMI at the age of 50 years they have history of myocardial infarction or stroke in the past. This risk profile reflects worse global systolic function of the left ventricle and higher hospital mortality after direct PCI.
