Cardiovascular disease and cancer frequently coexist, and patients with cancer are at increased risk of cardiovascular events, including myocardial infarction and stroke. However, the impact of stent types on in-hospital outcomes of patients with malignancy is largely unknown.Patients with concomitant diagnosis of cancer undergoing PCI between January 2005 and December 2014 were identified in the National Inpatient Sample. They were then categorized into those who have undergone coronary stenting with bare-metal stent (BMS) or drug-eluting stent (DES). Primary outcomes were in-hospital mortality and stent thrombosis. Adjusted and unadjusted analysis was employed on appropriate variables of interest.8755 patients were included in the BMS group and 11,611 patients in the DES group. Following propensity matching, 4313 patients were randomly selected in both groups using a 1:1 ratio. There was high use of BMS stent in cancer patient (BMS 43.0%, DES 57.0%) compared to general population (BMS 23.2%, DES 76.8%). When comparing BMS to DES group, there was no statistically significant difference in mortality (4.7% vs. 3.8%, p = 0.097), acute kidney injury (11.3% vs. 10.6%, p = 0.425), bleeding complications (3.50% vs. 3.45%, p = 0.914), and length of hospital stay (5.4% vs. 5.2%, p = 0.119). However, an increased incidence of stent thrombosis was observed in the DES group (4.26% vs. 3.01%, p = 0.002).A higher incidence of BMS placement was noted in patients with cancer than in the general population. Paradoxically there was a high incidence of stent thrombosis in the DES group without increasing mortality. |
