Among ACS patients surviving 30 days, women had a lower risk of late mortality than men after adjusting for confounders (HR 0.86; 95% CI 0.76-0.98; p=0.02).

Does gender affect long-term mortality and its predictors in patients surviving 30 days after an acute coronary syndrome?
In patients surviving 30 days post-ACS, women have lower long-term mortality than men after age adjustment, with different baseline predictors of mortality between genders.
Hazard Ratio: 0.86 (95% CI 0.76–0.98)
Absolute Event Rate: 62.4% vs 56.2%
p-value: p=0.02
BACKGROUND: Gender differences in outcome and its predictors in patients with acute coronary syndrome (ACS) continue to be debated. OBJECTIVES: To assess long-term mortality and explore its association with the baseline variables in women and men. METHODS: We followed 2,176 consecutive patients (665 women and 1,511 men) with ACS admitted to a single hospital and still alive after 30 days for a median of 16 years 8 months. RESULTS: At the end of the follow-up, 415 (62.4%) women and 849 (56.2%) men had died (unadjusted hazard ratio HR for women/men 1.18 (95% confidence interval CI, 1.05-1.33, p =0.005). After adjustment for age, the HR was reversed to 0.88 (95% CI, 0.78-1.00, p =0.04). Additional adjustment for potential confounders yielded a HR of 0.86 (95% CI, 0.76-0.98, p = 0.02). Using multivariable Cox regression, previous heart failure, previous or new-onset atrial fibrillation, and psychotropic drugs at discharge were significantly associated with increased long-term mortality in men only. Known hypertension, elevated creatinine, and inhospital Killip class >1/cardiogenic shock were significantly associated with mortality only in women. For late mortality, hypertension and inhospital Killip class >1/cardiogenic shock interacted significantly with gender. CONCLUSION: For patients with ACS surviving the first 30 days, late mortality was lower in women than in men after adjusting for age. The effects of several baseline characteristics on late outcome differed between women and men. Gender-specific strategies for long-term follow-up of ACS patients should be considered.
Ravn‐Fischer et al. (Tue,) conducted a cohort in Acute coronary syndrome (n=2,176). Female gender vs. Male gender was evaluated on Long-term mortality (HR 0.86, 95% CI 0.76-0.98, p=0.02). Among ACS patients surviving 30 days, women had a lower risk of late mortality than men after adjusting for confounders (HR 0.86; 95% CI 0.76-0.98; p=0.02).
