Objective:

to identify gender differences in clinical presentation, treatment and mortality rate of patients treated with primary coronary angioplasty (PTCA) in STEMI.

Methods and results:

historical cohort of 7.742 PTCA within 24 hours of STEMI in 7.337 patients (30.9% women) from 2004 to 2012 in Uruguay, under national financial coverage of the “Fondo Nacional de Recursos” were studied. Median follow-up was 4.3 years.

Female patients were significantly older than men, age 67.9 ± 12.1 versus 60.8 ±11.7 years (p=0.009). The rate of diabetes and cardiogenic shock were significantly higher in women versus men, respectively 24.4% vs 18.4%, p<0.001 and 7.6% vs 5.2%, p<0.001. Women received less treatment with fibrinolitics (5.5% vs 8.1%, p<0.001) and were performed less multivessel angioplasty (7.3% vs 9%, p< 0.013). They had higher mortality rate at the procedure day (2.9% vs 1.7%, p<0.001), 30 days (10.4% vs 6.5%, p<0.001), one year (15.4% vs 10.8%, p<0.001) and 5 years (27.9% vs 26.6%, p<0.001). In the multivariate analysis, female gender was not an independent predictor of 30-day mortality.

Conclusion:

Despite women with STEMI present with higher risk characteristics, they were less completely treated and their mortality rate at any time of the follow-up was higher than that of men. However, being a woman was not an independent predictor of 30-day mortality.
