Does a history of cancer (active or past) increase in-hospital and 1-year mortality in adults hospitalized for a first acute myocardial infarction?
In a large real-world AMI population, active cancer—particularly lung and haematological malignancies—significantly worsens 1-year survival, whereas past cancer shows no excess mortality, highlighting the need to integrate active cancer status into AMI risk stratification.
Cancer history was associated with higher 1-year post-AMI mortality; leaves open its integration into risk stratification.
Background Cancer is common among patients with acute myocardial infarction (AMI) and may influence management and outcomes. The prognostic impact of cancer status (active vs. past) and its anatomical site remains insufficiently defined. We evaluated the association between cancer and short- and long-term outcomes after AMI in a large population cohort. Methods Using linked administrative databases from Lombardy, Italy, we identified adults with a first AMI hospitalization from 2014–2022 (N=124,403). Patients were categorized by cancer history, cancer status (active vs. past), and cancer site. The primary endpoint was in-hospital mortality; secondary endpoints were 1-year all-cause mortality and 1-year rehospitalization for AMI or acute heart failure (AHF). Multivariable log-binomial, Cox, and Fine&Gray models were applied. Results Overall, 18,463 (14.8%) had a history of cancer. They were older and with higher comorbidity burden. Cancer history was associated with higher in-hospital mortality (adjusted risk ratio [RR] 1.06, 95% CI 0.99–1.13) and one-year mortality (adjusted hazard ratio [HR] 1.50, 95% CI 1.44–1.57). Active cancer carried the greatest risk (in-hospital RR 1.07, 95% CI 1.00–1.15; 1-year HR 1.64, 95% CI 1.57–1.72), whereas past cancer showed no excess mortality. Site-specific analyses identified lung (one-year HR 2.69, 95% CI 2.15–3.37) and haematological cancers (one-year HR 2.19, 95% CI 1.88–2.56) as highest risk. Elevated mortality with cancer was consistent in STEMI and NSTEMI. Competing-risk analyses showed similar risk of rehospitalization among cancer and non-cancer patients. Conclusions In a real-world, unselected AMI population, cancer worsens short- and long-term survival, especially when active and involving the lungs or the haematopoietic tissues. Incorporating cancer status into AMI risk stratification and strengthening cardio-oncology pathways in acute care are warranted to improve patient outcomes.

Cosentino et al. (2026) conducted a cohort in Acute myocardial infarction (n=124,403). Cancer history (active or past) vs. No history of cancer was evaluated on In-hospital mortality (RR 1.06, 95% CI 0.99-1.13). Cancer history in AMI patients was associated with higher in-hospital mortality (adjusted RR 1.06, 95% CI 0.99-1.13) and 1-year mortality (adjusted HR 1.50, 95% CI 1.44-1.57).
