Abstract

Abstract : Objective: To access the difference in clinical characteristics and prognostic outcomes between men and women who were admitted in our Cardiac Intensive Care Unit with STEMI diagnosis. Design and method: We retrospectively analyzed 121 patients with STEMI, during a mean follow-up period 135 ± 31 weeks. We accessed baseline characteristics and time course of events. Primary endpoint (PE) was a composite of in-hospital cardiovascular death, arrhythmic events or STEMI evolution in Killip-Kimbal III or IV. Secondary endpoint (SE) was in-hospital major bleeding events and tertiary endpoint (TE) included admissions to the emergency department or hospitalization by heart failure decompensation, acute or chronic coronary syndromes and all-cause mortality. Results: Of the 121 patients, 102 were male (84.3%). The mean age was 58.3 ± 12.7 years and women had a superior mean age (69.8 ± 12.2 years). Hypertension was more prevalent in women (84.2% vs. 47.1%, respectively; p 0.003) and also diabetes – 36.8% of women had type 2 diabetes and 5.3% of these female patients requires insulin therapy (vs 2% of men; p 0.021). According to Charlson Comorbidity Index (CCI), women had a higher disease burden with 73.7% of them included into the moderate or severe group of mortality risk, compared to 42.2% of men (p 0.014). Conversely, less women smoke (31.6% vs. 82.2%; p < 0.001) and less frequently chest pain was the onset symptom (78.9% vs. 95.1%; p 0.04). Time since symptom onset to door admission was estimated on 510 ± 1149 minutes and the mean women delay was superior (557 ± 858 minutes). Regarding to in-hospital hemorrhagic events, female patients had a statistically significant higher risk (22.2% vs. 7.1%, p 0.045), independently of hypertension, diabetes or anticoagulant therapy (r = 0.249; ANOVA p-value < 0.005), but it was associated with higher CCI (p 0.033). No other gender differences in outcomes were observed. Conclusions: Our study demonstrates gender-related differences among patients with STEMI. Indeed, women were older, had more clinical cardiovascular risk factors and tend to delay hospital admission after symptoms onset. Secondary endpoint was statistically more frequent in women, but no other differences in outcomes were observed.
