Outcomes for Cancer Patients with Acute ST-Segment Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention.

BACKGROUND/PURPOSE: The incidence of cardiovascular disease in cancer patients is rising. The risk of in-hospital complications for cancer patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) is not well defined.

METHODS/MATERIALS: A retrospective single-center cohort assessing STEMI patients with a history of cancer (n = 58) and without a history of cancer (n = 551) who underwent primary PCI between January 1, 2012 and June 30, 2017 was conducted. The primary outcome was a composite of in-hospital complications including reinfarction, cardiogenic shock, new heart failure, stroke, new atrial fibrillation, ventricular tachycardia/fibrillation, cardiac arrest, bleeding, new dialysis requirement, mechanical circulatory support, hospice requirement, and in-hospital mortality.

RESULTS: Overall in-hospital complications occurred in 229 (37.6%) patients. There was no significant difference in overall complications in patients with a history of cancer (39.7%), compared to those without a cancer history (37.4%) (adjusted OR 0.84 [0.46-1.51], p = 0.58; unadjusted OR 1.10 [0.61-1.92], p = 0.73); there were no differences exhibited in any of the individual complications. Patients with a history of cancer were significantly more likely to be readmitted within 30 days (12.7% vs. 5%; p = 0.03) and receive bare metal stents (50% vs. 30.4%; p = 0.004) as compared to patients without a history of cancer.

CONCLUSIONS: There was no significant difference for in-hospital complications in patients with a history of cancer and those without a history of cancer undergoing primary PCI for STEMI. Patients with a history of cancer were more likely to readmitted within 30 days and receive bare metal stents.

SUMMARY: The risk of in-hospital complications for cancer patients with STEMI undergoing primary PCI is not well defined. In a single-center retrospective cohort, there was no significant difference for in-hospital complications between patients with a history of cancer and those without a history of cancer undergoing primary PCI for STEMI.
