Prasugrel switching from clopidogrel after percutaneous coronary intervention for acute coronary syndrome in Taiwanese patients: an analysis of safety and efficacy. Cardiovasc Interv Ther 2021; 37:269-278. [PMID: 33813727 PMCID: PMC8926957 DOI: 10.1007/s12928-021-00771-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Accepted: 03/20/2021] [Indexed: 11/25/2022]
Abstract
The recommended maintenance dose of prasugrel for East Asian populations (i.e., Japanese and Taiwanese) is 3.75 mg as part of dual antiplatelet therapy (DAPT) for the prevention of recurrent ischemia and stent thrombosis in acute coronary syndrome (ACS). This modified dosage regimen has been established in studies conducted in Japan; however, the efficacy and safety of switching from clopidogrel to prasugrel DAPT among Taiwanese patients remain to be explored. In this phase IV, multicenter, single-arm, open-label study, we evaluated the 4-week pharmacodynamic response, and the 48-week safety outcomes of prasugrel 3.75 mg after a switch from clopidogrel in Taiwanese ACS patients. A total of 203 prasugrel-naïve ACS patients (over 90% male) who had received post-PCI clopidogrel DAPT for at least 2 weeks were enrolled from ten medical centers in Taiwan and subsequently switched to prasugrel 3.75 mg DAPT. Four weeks after the switch, P2Y12 reaction unit (PRU) values were significantly decreased in the total cohort (mean − 18.2 ± 48.1; 95% confidence interval − 24.9 to − 11.5, p < 0.001), and there was an overall consistent antiplatelet response in the treated subjects. The proportion of patients with high on-treatment platelet reactivity (HPR; PRU > 208) dropped from 23.5 to 10% (p < 0.001). Female sex was associated with a greater PRU reduction with prasugrel, whereas HPR at baseline, age ≥ 65 years, and body mass index ≥ 25 best predicted HPR at Week 4. Throughout the 48-week treatment with prasugrel, the incidences of MACE (1.0%) and TIMI major bleeding (2.0%) were rather low, accompanying an acceptable safety profile of TIMI minor (6.4%) and non-major, non-minor clinically relevant bleeding (3.0%). Overall, switching to the maintenance dose of prasugrel (3.75 mg) was observed to be effective and well tolerated among post-PCI ACS patients in Taiwan. Clinical Trial Registration Number: NCT03672097.

Abstract
To date, DAPT duration of 1 year is the standard treatment for ACS patients after DES implantation in China. However, less is known about the effect of prolonging DAPT duration of long-term outcome for this kind of patient in the real world of China. We carried out a large sample case in the biggest cardiovascular center in China to observe the effect of prolonging DAPT duration for more than 1 year on long-term outcome in ACS patients after PCI. We enrolled 5187 consecutive patients with ACS who underwent DES implantation from January 2013 to December 2013. We recorded when DAPT was discontinued, and analyzed patients' data comparing different DAPT durations (DAPT = 1 year or >1 year). Two-year clinical outcomes were compared between patients from the two groups. The baseline characteristics were almost the same between the two groups, except the number of stents per patient (DAPT = 1 year vs. >1 year, 1.80 ± 1.02 vs. 1.86 ± 1.05, p = .04). Patients with DAPT = 1 year had a higher incidence of all-cause death (1.8% vs. 0.1%, p < .01), cardiac death (0.8% vs. 0.1%, p < .01), and stent thrombosis (0.7% vs. 0.2%, p < .01) vs. DAPT > 1 year, respectively. Logistic regression analysis indicated that the number of stents per patient was an independent factor for prolonged DAPT (odds ratio: 1.07, 95% confidence interval (CI): 1.01-1.14, p = .03). Cox regression analysis showed that the independent risk predictors of all-cause death were age and cardiac dysfunction, whereas the independent protective predictors were body mass index and DAPT > 1 year. In the subgroup analysis of high bleeding risk, the DAPT > 1-year group still experienced a lower incidence of all-cause death. For patients with ACS undergoing DES implantation, 1 year of DAPT may be not sufficient. Appropriate prolongation of DAPT may relate to the reduction of the incidence of adverse cardiovascular events and it does not increase the bleeding events, even for the patients with high bleeding risk.

Abstract
One of the major missions of the Taiwan Society of Cardiology is to publish practice guidelines that are suitable for local use in Taiwan. The ultimate purpose is to continuously improve cardiovascular health care from the implementation of the recommendations in the guidelines. Despite recent improvement of medical care, patients with ST-segment elevation myocardial infarction (STEMI) still carry a high morbidity and mortality. There have been many changes in the concepts of STEMI diagnosis and treatment in recent years. The 2020 focused update of the 2012 guidelines of the Taiwan Society of Cardiology for the management of STEMI is an amendment of the 2012 guidelines based on the newest published scientific data. The recommendations in this focused update provide the diagnosis and treatment strategy for STEMI that should be generally implemented in Taiwan. Nevertheless, guidelines never completely replace clinical judgment and medical decision still should be determined individually.
