One-Month Outcomes of Cases Receiving Ticagrelor after Percutaneous Coronary Intervention; a Case Series

Introduction: Ticagrelor is the first reversibly binding oral P2Y12 receptor antagonist that can block ADPinduced platelet aggregation. This study aimed to describe one-month follow-up findings of cases undergoing ticagrelor therapy after percutaneous coronary intervention (PCI). Methods: This case series was performed on acute coronary syndrome (ACS) patients who were candidates for PCI and received aspirin plus ticagrelor after PCI. Patients were followed for one month and their outcomes were described. Results: 156 cases with the mean age of 59.74 § 9.24 years were studied (63% male). 45 (28.8%) cases complained of dyspnea (39 cases with mild and 6 cases with severe dyspnea). Bleeding occurred in 4 (2.5%) cases (intra-cranial hemorrhage (ICH) in one, hematuria in two, and skin hemorrhage in one case). There were no cases with bradycardia or thrombosis. One (0.6%) patient developed drug hypersensitivity reaction, which manifested as skin rash. The use of drug was stopped in 10 (6.4%) cases due to severe dyspnea (n= 6), ICH (n=1), skin rash (n=1), and concomitant left ventricular (LV) clot (n=2). Conclusion: The most important finding of one-month ticagrelor consumption were dyspnea, bleeding, and hypersensitivity reaction. No case of bradycardia and stent thrombosis was detected. In our study, iranian population has more susceptibility to dyspnea than PLATO result. The rate of drug discontinuation in this series of cases was 6.4%.
