Abstract:
Objective Ticagrelor-related dyspnea may affect the medication adherence of patients with coronary artery disease.This study aims to assess the impact of ticagrelor adherence on 1-year cardiovascular outcomes in pateints with stable coronary artery diseases (SCAD).Methods This study includes the patients with SCAD from Fuwai hospital who discharged with ticagrelor between Jan.2015 to Jun.2015.We collected data of clinical characteristics and ticagrelor adherence from these patients by reviewing the electronic medical records and personnel interview.Follow-up was performed at 6 and 12 months by telephone interview or office visits.Results A total of 155 patients with SCAD were enrolled,of whom 122 (78.7％) were males with a mean age (57.0 ± 10.0) years.Among them,50 (32.3％) patients have a history of myocardial infraction and 106 (68.4％) patients had angiographic confirmed left main and/or multivessel disease.Forty-six patients (29.7％) with SCAD prematurely stopped ticagrelor within 12 months,while 25 (16.1％) patients switched from ticagrelor to clopidogrel.Hemorrhagic events and locally unavailable ticagrelor were the major reasons causes of the premature discontinuation of ticagrelor.Univariate analysis showed age,body mass index (BMI),hypertention and locally unavailable ticagrelor as relative factors for early ticagrelor discontinuation after discharge.Multivariate analysis revealed unavailable drug locally (OR 0.25,95％ CI 0.09-0.69) and elderly patients (OR 4.13,95％ CI 1.40-12.19) were risk factors for low persientence or premature ticagrelor discontinuation.Conclusion This study showed poor ticagrelor adherence in patients with SCAD after discharge.Locally unavailable ticagrelor and elderly patients were strong predictors of poor ticagrelor adherence.Discontinuation to ticagrelor prematurely may not have impact on adverse cardiovascular outcomes.
