Abstract

Background Progress in cancer treatments have significantly improved patient outcomes, leading to increased survival rates. However, patients with cancer continue to have higher rates of cardiovascular events an area that has traditionally not received much attention. Purpose The aim of this study was to examine the risk of myocardial infarction in patients with different types of cancer compared with age- and sex-matched population controls with benign skin cancer. Methods Patients with cancer between 2000-2016 were identified within the Danish National Patient Registry. Cox regression was used accounting for the competing risk of death reporting hazard ratios (HR) for both myocardial infarction and mortality. Models were adjusted for age, sex, hypercholesterolemia, atrial fibrillation, hypertension and anticoagulant therapies of all included subjects. Patients with a previous myocardial infarction were excluded from the analysis. Results A total of 503.616 patients were included in the final analysis of whom 355.920 had cancer with different cancer types and 147.696 were controls with benign skin cancer. The one-year outcome of myocardial infarction (Figure 1) was overall significant higher for all subtypes of cancer especially lymphoma HR 1.66 (interquartile range [IQR]: 1.45-1.89), bladder cancer HR 1.64 (IQR: 1.39-1.94), and gastrointestinal cancer HR 1.53 (IQR: 1.40-1.69). Hepatobiliary and pancreatic cancer, breast cancer and malignant melanoma had reduced but not significantly different HRs of 0.96 (IQR: 0.80-1.15), 0.92 (IQR: 0.79-1.07), and 0.76 (IQR: 0.60-0.96), respectively. The one-year competing risk of death (Figure 2) was overall higher for all subtybes of cancer especially hepatobiliary and pancreatic cancer and lung cancer with HRs of 52.11 (IQR: 50.18-54.11) and 41.62 (IQR: 40.17-43.12). Conclusion The one-year risk of myocardial infarction varied across cancer subtypes. Notably, lymphoma, bladder, and gastrointestinal cancers were associated with higher risks, whereas hepatobiliary and pancreatic, breast, and malignant melanoma cancer showed no statistically significant associations. The clinical significance of these differences must be viewed within the context of the significant competing risk of death in this cancer population.Risk Of Myocardial InfarctionCompeting Risk Of Death
