Patients with a history of malignancy are at elevated risk for acute coronary syndrome (ACS). This study evaluates in-hospital cardiovascular outcomes in ACS patients with and without a cancer history.
Methods
A systematic search of PubMed, Scopus, Embase, and ClinicalTrials.gov (2000–2025) identified studies comparing in-hospital outcomes for ACS in patients with vs. without malignancy. Data were pooled and analyzed using RevMan 5.4, calculating risk ratios (RRs) under a random-effects model.
Results
Fifteen studies were included. Among ACS patients, a history of cancer was associated with significantly worse in-hospital outcomes. Cancer history increased all-cause mortality by 44% [RR: 1.44; 95% confidence interval (CI): 1.21–1.71;
Conclusion
Patients with a history of malignancy presenting with ACS face significantly higher in-hospital risks of mortality, bleeding, MACE, and stroke, while risks of heart failure, re-infarction, and shock show nonsignificant trends. These findings underscore the vulnerability of this population and highlight the need for multidisciplinary, individualized management strategies to improve outcomes.
