RESUMEN
The aim of the study was to analyze clinical features of patients with premature acute coronary syndrome (ACS) in relation to family history of cardiovascular disease (CVD) and familial hypercholesterolemia (FH). MATERIALS AND METHODS: Of 2832 patients included in ORACUL 1 and ORACUL 2 multicenter observational trials 512 pts who developed premature ACS (≤55 years for men, ≤60 years for women) and had known family history and LDL level were selected for this study. Of these patients 297 had positive family history (51 with FH, 246 no FH), 215 had negative family history. RESULTS: Among patients with positive family history there were more women (31 vs 20.9 %), while among patients with negative family history there were more men (79.1 vs 69 %). The fact of regular alcohol consumption was significantly more frequently observed among patients with positive family history but without FH, compared to patients with positive family history with FH (69.6 vs 47.1 %). Women with positive family history smoked more frequently than females with negative family history (51.1 vs 31.1 %). Among patients with negative family history compared with patients with positive family history there were more people who at admission had hyperglycemia exceeding 11.1 mmol / l (10.3 vs 4.4 %). Multiple vessel disease and coronary calcinosis were present in 73.2 and 24.7 %, respectively, of patients with positive family history, and in 56.9 and 9.8 %, respectively, of those with negative family history. Among patients with positive family history multivessel disease was more frequent in the subgroup with FH, while coronary calcinosis was more frequent in the subgroup without FH. CONCLUSION: Thus, premature development of ACS might be associated not only with genetic factors but also with family history ("inheritance") of adverse habits. Herewith coronary calcinosis is more prevalent in patients with FH.
