Ticagrelor monotherapy reduces bleeding risk in patients undergoing PCI with and without CKD: Study
According to a study published in the European Heart Journal ticagrelor monotherapy reduces significant bleeding without significantly increasing adverse events in patients with and without Chronic Kidney Disease (CKD).
The authors aimed to assess the impact of chronic kidney disease (CKD) on the safety and efficacy of ticagrelor monotherapy among patients undergoing percutaneous coronary intervention (PCI).
In this prespecified subanalysis of the TWILIGHT trial, we evaluated the treatment effects of ticagrelor with or without aspirin according to renal function. The trial enrolled patients undergoing drug-eluting stent implantation who fulfilled at least one clinical and one angiographic high-risk criterion. Chronic kidney disease, defined as an estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2, was a clinical study entry criterion. Following a 3-month period of ticagrelor plus aspirin, event-free patients were randomly assigned to aspirin or placebo on top of ticagrelor for an additional 12 months.
The results of the study are as follows:
· Of the 6835 patients randomized and with available eGFR at baseline, 1111 (16.3%) had CKD.
· Ticagrelor plus placebo reduced the primary endpoint of Bleeding Academic Research Consortium (BARC) type 2, 3, or 5 bleeding as compared with ticagrelor plus aspirin in both patients with and without CKD, but the absolute risk reduction was greater in the former group.
· Rates of death, myocardial infarction or stroke was not significantly different between the two randomized groups irrespective of the presence or absence of Chronic Kidney disease (CKD).
Thus, the researchers concluded that among CKD patients undergoing PCI, ticagrelor monotherapy reduced the risk of bleeding without a significant increase in ischaemic events as compared with ticagrelor plus aspirin.
