Impact of Active and Historical Cancer on Short- and Long-Term Outcomes in Patients With Acute Myocardial Infarction

Patients with cancer have an increased risk of cardiovascular events including myocardial infarction (MI) and vice versa, and are at high risks of ischemic and bleeding events after MI. However, short- and long-term clinical outcomes in patients with acute MI based on cancer status are not fully understood. This bi-center registry included 903 patients with acute MI undergoing primary percutaneous coronary intervention in a contemporary setting. Patients were divided into active cancer, a history of cancer, and no cancer according to the status of malignancy. Major adverse cardiovascular events (MACE), a composite of all-cause death, recurrent MI, and stroke, and major bleedings were evaluated. Of 903 patients, 49 (5.4%) and 65 (7.2%) had active cancer and a history of cancer, and 87 (9.6%) patients died during the hospitalization. In-hospital MACE was not significantly different among the 3 groups (16.3% vs 10.8% vs 10.9%, p = 0.48), whereas the rate of major bleeding events during the index hospitalization was significantly higher in patients with active cancer than their counterpart (20.4% vs 6.2% vs 5.8%, p = 0.002). After discharge, patients with active cancer had an increased risk of MACE and major bleedings compared with those with a history of cancer and no cancer during the mean follow-up period of 853 days. In conclusions, active cancer rather than a history of cancer and no cancer had significant impact on in-hospital bleeding events, and MACE and major bleedings after discharge in patients with acute MI undergoing primary percutaneous coronary intervention.
