- Women had a higher unadjusted rate of death in the hospital than men in both the STEMI (9.4 per cent vs. 4.5 per cent) and NSTEMI (4.7 per cent vs, 2.9 per cent) groups. However, the gap narrowed considerably for NSTEMI after confounder adjustments.
- Women were more likely to be an average of 10 years older than men at the time of their heart attack, usually an average age of 72 years versus 61 for the men.
- Women also had more complicated medical histories at the time of their heart attacks, including high blood pressure, diabetes, atrial fibrillation, and chronic obstructive pulmonary disease, risk factors that may contribute to heart failure.
- Women were seen less frequently in the hospital by a cardiovascular specialist: 72.8 per cent versus 84 per cent for men.
- Regardless of whether their heart attacks were the severe or less severe type, fewer women were prescribed medications such as beta-blockers or cholesterol-lowering drugs. Women also had slightly lower rates of revascularization procedures to restore blood flow, such as surgical angioplasty.
"Identifying when and how women may be at higher risk for heart failure after a heart attack can help providers develop more effective approaches for prevention," said lead study author Justin A. Ezekowitz, M.B.B.Ch., M.Sc., a cardiologist and co-director of the Canadian VIGOUR Centre at the University of Alberta in Edmonton, Alberta, Canada. "Better adherence to reducing cholesterol, controlling high blood pressure, getting more exercise, eating a healthy diet and stopping smoking, combined with recognition of these problems earlier in life would save thousands of lives of women - and men."
Based on these findings, study co-author Padma Kaul, PhD, co-director of the Canadian VIGOUR Centre, said the next step is to further examine if all patients are receiving the best care, particularly women, and where interventions can address oversights.
"Close enough is not good enough," said Kaul, who is also the Sex and Gender Science Chair from the Canadian Institutes of Health Research. "There are gaps across diagnosis, access, quality of care, and follow-up for all patients, so we need to be vigilant, pay attention to our own biases, and to those most vulnerable to ensure that we have done everything possible in providing the best treatment."
