People who have a heart attack but don’t have common risk factors like high blood pressure or smoking are actually more likely to die in the hospital than those who do have those risks — about 57% more likely, according to this study.

What we've found so far suggests that heart attack patients who don’t have traditional risk factors like high blood pressure or smoking may be more likely to die during their hospital stay compared to those who do have those risk factors. The evidence we've reviewed leans toward this outcome, based on the data we’ve analyzed to date. Our analysis of the available research shows that individuals without common risk factors for heart disease face a higher chance of in-hospital death after a heart attack. According to one study, these patients are about 57% more likely to die in the hospital than those with traditional risk factors [1]. This finding may seem surprising, since we often assume that having risk factors like high blood pressure or a history of smoking increases the danger during a heart event. Yet, what we’ve found so far indicates the opposite when it comes to short-term survival in the hospital. We don’t yet know why this pattern exists. It’s possible that heart attacks in people without typical risks may be less expected, leading to delays in diagnosis or treatment. Or, the nature of their heart disease could be different in ways we don’t fully understand. Still, this single finding doesn’t give us the full picture—only one assertion was analyzed, even if it draws from a large body of work (42.0 supporting studies are noted, though we don’t have details on how they were counted or combined) [1]. Because the evidence base we’ve reviewed is limited in scope and comes from one main assertion, we can’t say how strong or generalizable this pattern is. Other factors like age, access to care, or genetic influences might also play important roles we haven’t accounted for. Practical takeaway: If you or someone you know has a heart attack—even without a history of high blood pressure, smoking, or other common risks—treatment should be taken just as seriously. Being “low risk” doesn’t necessarily mean a better outcome in the hospital, based on what we’ve seen so far.
