Clin Cardiol 2021; 44:1072-1079. [PMID: 34041774 PMCID: PMC8364718 DOI: 10.1002/clc.23653] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Revised: 05/11/2021] [Accepted: 05/18/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Clinical evidence of prasugrel/ticagrelor in dual antiplatelet therapy (DAPT) in Asian acute coronary syndrome (ACS) population remains inconclusive. We aimed to compare the clinical efficacy and safety of prasugrel/ticagrelor compared to clopidogrel as part of DAPT in Hong Kong ACS population for 10 years. HYPOTHESIS Prasugrel/ticagrelor, compared to clopidogrel, reduces risk of major adverse cardiovascular event (MACE) in Hong Kong ACS population. METHODS The retrospective observational cohort study included patients admitted to seven institutions under Hospital Authority Hong Kong with diagnosis of ACS during 2008-2017. Risk of MACE, defined as composite of cardiovascular (CV) death, non-fatal myocardial infarction (MI) and non-fatal stroke, and risk of any bleeding leading to hospitalization were examined. Baseline characteristics difference was adjusted by propensity score (PS) matching. Adjusted Cox regression model was used to estimate hazard ratio of interested outcome. RESULTS In PS matched cohort including 944 patients in each group, MACE risk reduction of 40% from 1 year to 5 years after index ACS event was observed in prasugrel/ticagrelor group (HR 0.60, 95% CI 0.39-0.91, p = .015). The risk reduction was highly driven by MI reduction (HR 0.54, 95% CI 0.33-0.91, p = .019). Lower bleeding risk was observed in prasugrel/ticagrelor group compared to clopidogrel from 1 year to 5 years (HR 0.46, 95% CI 0.21-1.00, p = .051). CONCLUSIONS Prasugrel/ticagrelor showed MACE risk reduction over clopidogrel as part of DAPT up to 5 years after index event, while prasugrel/ticagrelor was not associated with increased bleeding risk.

Comparative effectiveness and safety of prasugrel versus ticagrelor following percutaneous coronary intervention: An observational study. Pharmacotherapy 2021; 41:515-525. [PMID: 33932252 DOI: 10.1002/phar.2530] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Revised: 03/26/2021] [Accepted: 04/01/2021] [Indexed: 11/11/2022]
Abstract
BACKGROUND Observational studies comparing ticagrelor and prasugrel in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) have yielded contradictory results, but these studies often did not consider differential censoring (eg, for treatment switching or insurance disenrollment) or confounding by time-dependent factors. OBJECTIVE Our objective was to conduct a comparative effectiveness and safety analysis of ticagrelor and prasugrel in patients who underwent PCI after being hospitalized for an ACS. METHODS This study used the Optum's de-identified Clinformatics® Data Mart Database and included patients aged 18 years or older with an index hospital admission between May 2012 and September 2015, a diagnosis of ACS managed with PCI, and treatment with either ticagrelor or prasugrel. The primary composite outcome was defined as the first occurrence of all-cause death, myocardial infarction (MI), or ischemic stroke. The secondary composite outcome included the first occurrence of gastrointestinal (GI) bleed, intracranial hemorrhage (ICH), or other major bleeds requiring hospitalization. Weighted Cox proportional hazard models and robust variance estimation were implemented to adjust for baseline comorbidities, time-varying exposure, time-dependent confounders, and differential censoring. RESULTS Included in the analysis were 2559 patients initiated on ticagrelor and 4456 patients initiated on prasugrel following PCI. Patients initiated on ticagrelor were 10% more likely to have eligibility disenrollment (Ticagrelor: 57%, Prasugrel: 47%, p < 0.01) and 7 percentage-points more likely to switch medication (Ticagrelor: 35%, Prasugrel: 28%, p < 0.01). After adjusting for multiple factors, including time-varying exposure and censoring imbalance, ticagrelor was associated with a higher risk of all-cause death, MI, or stroke when compared to prasugrel (Hazard ratio (HR): 1.33; 95% CI: 1.04-1.68). Similarly, ticagrelor was associated with a higher risk in bleeding events when compared with prasugrel (HR: 1.61; 95% CI: 1.19-2.17). CONCLUSION When compared with ticagrelor, prasugrel use following PCI for ACS was associated with a lower risk of death, MI, or stroke, as well as a reduced risk of major bleeding.

Risk Stratification after an Acute Coronary Syndrome: Significance of Antithrombotic Therapy. J Clin Med 2021; 10:jcm10081572. [PMID: 33917922 PMCID: PMC8068298 DOI: 10.3390/jcm10081572] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Revised: 04/03/2021] [Accepted: 04/06/2021] [Indexed: 11/17/2022] Open
Abstract
The impact of the de-escalation strategy of antiplatelet therapy (APT) on the life expectancy after acute coronary syndromes (ACS) and percutaneous coronary intervention (PCI) requires an assessment in real clinical practice. Into the Russian multicentral observational trial (ORACLE II ClinicalTrials.gov number, NCT04068909), 1803 patients with ACS and PCI indications were enrolled. During 12 months of follow-up, 228 all-cause deaths have occurred. The analysis of death predictors was carried out by the classification tree method. Age, an option of antithrombotic therapy, a history of chronic heart failure, and uric acid level had the greatest prognostic value. The death prediction model's sensitivity was 82.1% in the training cohort and 79.2% in the test cohort. During the observation period, ticagrelor was replaced with clopidogrel (APT de-escalation) in 357 patients. The groups of patients with different antiplatelet therapy options were adjusted for clinical parameters by the pseudorandomization method. The de-escalation group had the lowerest all-cause death rate. The incidence of bleeding and recurrent nonfatal coronary events in the study groups did not differ significantly. Thus, the APT regimen's advantage of changing from the maximum in the first weeks after ACS to moderate at follow-up has been confirmed. There is an obvious need to study the possibilities of individualizing antiplatelet therapy in patients after acute coronary syndromes.

Abstract
Objective. To design, integrate the curriculum for, and evaluate an innovative program to facilitate placement of students into postgraduate pharmacy residency training programs involving direct patient care. Methods. The Pharmacotherapy Scholars Program (PSP) was designed to prepare fourth-professional year students to become highly proficient in a direct patient care role and to successfully match with postgraduate residency training programs. The following elements were included in the year-long curriculum: integrated synchronous advanced pharmacy practice experiences with personal advising, team-based mentoring, peer-to-peer learning, longitudinal research, and professional development. Program goals were modeled after the accreditation standards for postgraduate year one (PGY1) pharmacy residency programs. Program faculty members ensured that the PSP had a broad scope, included rigorous student assessments, had a strong research focus, and provided scholarship opportunities. Results. Sixty-eight students completed the program from fall 2013 through spring 2019. The overall residency match rate was 93%. Students' performance on both knowledge and clinical skills assessments significantly improved after completing the program. There was an approximately 15% increase in knowledge and a 30% improvement in clinical skills based on comprehensive readiness assessments and an intermittent clinical examination that used patient simulation, respectively. Conclusion. The Pharmacotherapy Scholars Program is an innovative training program designed to enhance PharmD students' preparation for advanced clinical training. Students who completed the PSP achieved a high PGY1 residency placement rate while demonstrating significant improvements in pharmacotherapy knowledge and clinical skills in direct patient care activities.

Abstract
BACKGROUND Depression and coronary artery disease (CAD) are leading causes of death and disability and commonly co-occur. Different antidepressant classes have similar efficacy for depressed patients with CAD, but cardiovascular implications are unclear. Selective serotonin reuptake inhibitors (SSRIs) and mirtazapine are first-line options for depressed patients with CAD. SSRIs, but not mirtazapine, have known antiplatelet effects. Whether this affects risk of bleeding and major adverse cardiac events (MACE) in patients requiring dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) is unknown. OBJECTIVE The aim of this analysis is to examine the impact of SSRI treatment on the co-primary endpoints of composite MACE (death, myocardial infarction, or stroke) and composite bleeding events in patients treated with clopidogrel-based DAPT after PCI. METHODS We conducted a retrospective study with co-primary endpoints of bleeding and MACE within 1 year of PCI. Three groups were compared: SSRI patients, mirtazapine patients, and patients on neither agent. Mirtazapine acted as a comparator to control for depression, for which diagnosis coding was inadequate. Time-to-event analyses were performed with Kaplan-Meier estimators and adjusted analyses utilized Cox proportional hazards. There were 6874 (820 SSRI, 55 mirtazapine, 5999 neither) patients included. RESULTS SSRI patients had lower MACE risk than mirtazapine patients (hazard ratio [HR] 0.61, 95% confidence interval [CI] 0.38-0.97, p = 0.036) but higher MACE risk than patients on neither agent (HR 1.21, 95% CI 1.02-1.43, p = 0.030) in adjusted analyses. No significant differences were associated with bleeding risk (SSRI vs. neither adjusted HR 1.07, 95% CI 0.93-1.24, p = 0.36). CONCLUSION SSRI use was associated with a significant decrease in MACE rates compared with patients receiving mirtazapine. Bleeding risk was not affected by either antidepressant treatment. SSRIs may have cardioprotective benefits compared with mirtazapine.

Abstract
De-escalation from ticagrelor to clopidogrel in acute coronary syndrome (ACS) may occur for a variety of reasons, including side effects (bleeding and non-bleeding) and costs. This study sought to assess the prevalence of de-escalation from ticagrelor to clopidogrel and the occurrence of adverse clinical outcomes following de-escalation. We conducted a systematic review of clinical trials and real-world studies in ACS patients treated with ticagrelor. Real-world data on the prevalence of de-escalation during hospitalization or at discharge, after hospital discharge, and during the whole study period were included for meta-analysis. Major adverse cardiovascular events (MACE) and bleeding events occurring after de-escalation were also assessed. A total of 12 studies were eligible for meta-analysis of the prevalence of de-escalation. De-escalation from ticagrelor to clopidogrel therapy occurred with a mean prevalence of 19.8% [95% confidence interval (CI) 11.2-28.4%]. De-escalation occurred more frequently in-hospital or at discharge than after hospital discharge (23.7% vs. 15.8%). For assessment of clinical outcomes, a total of six studies were eligible for meta-analysis. Mean rate of MACE for patients with de-escalation was 2.1% (95% CI 1.1-4.1%) and the rate of major bleeding events was 1.3% (95% CI 0.4-4.5%). In conclusion, de-escalation commonly occurs in real-world practice. Although rates of major cardiovascular and bleeding events in this analysis were generally low, the profile of patients suitable for de-escalation, the impact of de-escalation on adverse clinical outcomes and how this is affected by the timing after index ACS warrants further large-scale investigation.
