Cancer patients face a hidden heart risk. A large South Korean study found that while cancer patients have a slightly lower rate of heart attacks than the general population, they're more than twice as likely to die from cardiovascular causes. Researchers warn that acute MI in this group is being underdiagnosed and undertreated — and that revascularization significantly cuts the risk of CV death.
Cancer patients face a hidden heart risk
A major retrospective study using South Korean national health data found a striking paradox: cancer patients experience heart attacks at a slightly lower rate than the general population, yet are more than twice as likely to die from cardiovascular causes. Researchers believe this isn't because cancer protects the heart — it's because competing mortality risks and a tendency toward less aggressive cardiac care may be masking the true burden of acute MI in this group.
The study, presented at the TCT Scientific Symposium and published in JACC: Asia, analyzed data from over 682,000 cancer patients and an equal number of matched non-cancer individuals. Patients with pancreatic, hepatic, lung, and hematologic cancers faced the highest CV death risk.
By the Numbers
Why it matters: Cancer patients are often steered away from invasive cardiac procedures, but this data suggests revascularization saves lives — and that the current conservative approach may be costing them.
