Close enough is not good enough.
A large Canadian study spanning nearly 45,000 patients has quietly confirmed what many in medicine have long suspected: the heart attack experience is not the same for women as it is for men. Women arrive older, carrying heavier burdens of chronic illness, and leave the hospital less often having received the full weight of specialist attention — a convergence of biological and systemic forces that raises their five-year risk of heart failure or death by 20 percent. The findings, drawn from nearly fifteen years of Alberta hospital records, ask not only what medicine knows about the female heart, but whether it has chosen to act on that knowledge.
- Women are dying in hospital after heart attacks at nearly twice the rate of men — 9.4 percent versus 4.5 percent for the most severe cases — a gap that demands urgent reckoning.
- The compounding disadvantages are striking: women present a decade older on average, with more diabetes, hypertension, and atrial fibrillation already in play before the cardiac event begins.
- Despite greater clinical complexity, women received specialist consultations only 72.8 percent of the time compared to 84 percent for men, and were prescribed fewer of the standard preventive medications.
- Researchers are calling for systematic reform — not just awareness, but measurable adherence to evidence-based protocols that treat sex-specific vulnerability as a clinical priority, not an afterthought.
A study published in Circulation, drawing on hospital records from Alberta, Canada between 2002 and 2016, tracked more than 45,000 heart attack patients over an average of six years. Its central finding was sobering: women face a 20 percent higher risk of developing heart failure or dying within five years of their first severe heart attack compared to men.
The disparity held across both types of heart attack examined. Whether patients suffered a STEMI — the more life-threatening variety — or the less severe NSTEMI, women consistently developed heart failure at higher rates. In-hospital mortality told the same story: 9.4 percent of women died following severe attacks, compared to 4.5 percent of men. Even for less severe cases, the gap persisted.
Part of the explanation lies in biology and timing. Women in the study were roughly a decade older at the time of their heart attacks — averaging 72 years versus 61 for men — and arrived with more complex medical histories, including higher rates of diabetes, hypertension, atrial fibrillation, and chronic lung disease. These conditions independently raise the risk of heart failure following a cardiac event.
But the data also pointed to a care gap that cannot be explained by age or illness alone. Women were less likely to receive cardiovascular specialist consultations during their hospital stays, and were prescribed beta-blockers and cholesterol-lowering medications at lower rates than men. Revascularization procedures were also slightly less common for women.
Lead researcher Justin Ezekowitz, a cardiologist at the University of Alberta, framed the findings as an opening for intervention, pointing to proven tools — cholesterol management, blood pressure control, lifestyle changes — that could save thousands of lives if applied more consistently. Co-author Padma Kaul, who holds a Sex and Gender Science Chair, was more pointed: "Close enough is not good enough," she said, urging clinicians to examine their own biases and ensure that the most vulnerable patients receive the full measure of care available to them.
A study of more than 45,000 heart attack patients has found that women face a 20 percent higher risk of developing heart failure or dying within five years after their first severe heart attack, compared to men. The research, published in Circulation, the flagship journal of the American Heart Association, examined hospital records from Alberta, Canada between 2002 and 2016, following patients for an average of 6.2 years.
The disparity emerged across both types of heart attack studied. Among the 24,737 patients who experienced a less severe form called NSTEMI, women made up 34.3 percent of the group. In the 20,327 cases of STEMI—the more life-threatening variety—women represented 26.5 percent. The pattern held steady: women developed heart failure at higher rates than men following both types of attack, even after researchers adjusted their analysis for other contributing factors.
The in-hospital mortality gap was stark. Women died at a rate of 9.4 percent following severe heart attacks, compared to 4.5 percent for men. After less severe attacks, the figures were 4.7 percent for women and 2.9 percent for men. Though the gap narrowed somewhat for the less severe cases once researchers accounted for other variables, the fundamental vulnerability remained.
Several factors appeared to compound the risk. Women in the study were typically about a decade older when they suffered their heart attacks—averaging 72 years old versus 61 for men. They also arrived at the hospital with more complicated medical histories. High blood pressure, diabetes, atrial fibrillation, and chronic obstructive pulmonary disease were more common among the women, conditions that themselves increase the likelihood of heart failure developing after a cardiac event.
Beyond the biology, the data suggested a care gap. Women were seen less frequently by cardiovascular specialists during their hospital stays: 72.8 percent of women received specialist consultation compared to 84 percent of men. They were also prescribed preventive medications at lower rates. Beta-blockers and cholesterol-lowering drugs—standard tools for reducing future cardiac risk—went to fewer women than men. Revascularization procedures, which restore blood flow to the heart, were also slightly less common for women.
Justin Ezekowitz, the lead researcher and a cardiologist at the University of Alberta's Canadian VIGOUR Centre, framed the findings as an opportunity. Identifying when women face elevated risk after a heart attack could help doctors develop better prevention strategies. He pointed to proven interventions: managing cholesterol, controlling blood pressure, increasing physical activity, improving diet, and quitting smoking. "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," he said.
Padma Kaul, the study's co-author and holder of the Sex and Gender Science Chair from the Canadian Institutes of Health Research, pushed further. The next step, she argued, was to examine whether all patients were receiving optimal care, particularly women, and to identify where interventions could close the gaps. "Close enough is not good enough," she said. "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."

La Conversación del Hearth Otra perspectiva de la historia
Why does a woman's age at the time of the heart attack matter so much here?
Because the body changes over time. A 72-year-old woman's heart has been working for seven more decades than a 61-year-old man's. She's more likely to have accumulated other conditions—diabetes, high blood pressure—that stress the heart further. When the attack comes, there's less reserve capacity to recover.
But couldn't the age difference alone explain the higher death rates?
That's what the researchers checked for. Even when they adjusted the numbers to account for age and other factors, women still had worse outcomes. So age explains some of it, but not all. Something else is happening.
The specialist consultation gap—12 percentage points—that seems significant.
It does. A cardiologist sees things a general physician might miss. They know the subtle signs that heart failure is developing. If you're not being seen by that specialist, those early warnings can slip past.
Are women asking for less care, or are they being offered less?
The data doesn't tell us that. But the pattern is consistent across medications, procedures, and consultations. It suggests a systemic issue, not individual choice.
What would change if hospitals took this seriously?
They'd start asking: Why is this woman not on a beta-blocker? Why hasn't she seen cardiology? They'd build systems to catch the gaps before they become deaths.
