Gender differences in mortality after acute myocardial infarction with mild to moderate heart failure.
BACKGROUND
Heart failure (HF) is associated with poor outcome after acute myocardial infarction (AMI). Women have higher mortality rate than men after AMI, however, it is unknown whether women with HF after AMI have different prognosis than men.


OBJECTIVE
To compare the prognosis of men and women with AMI and mild-moderate HF.


METHODS
We analyzed data of 3456 consecutive patients with AMI hospitalized in all cardiac care units in Israel during two nationwide surveys.


RESULTS
Among patients with AMI and HF on admission: women were older, had more risk factors, and were less likely to undergo percutaneous coronary angiography/intervention. Women with HF had higher (7-days, 30-days, and 1-year) crude mortality rates than men. However, adjusted mortality rates were not significantly different between genders.


CONCLUSIONS
Women with AMI complicated by HF had higher crude mortality rate than men that was eliminated after multivariate analysis, suggesting that the higher mortality rate may be attributed to increased prevalence of risk factors and lower rate of revascularization and medical therapies among women. Women with AMI and HF should be considered as a high-risk subgroup with adverse outcome. It remains to be determined whether more intensive management will improve their prognosis.
