Ticagrelor or prasugrel versus clopidogrel in patients undergoing percutaneous coronary intervention for chronic coronary syndromes.

ABSTRACT:

Background

Potent P2Y₁₂ inhibitors such as ticagrelor and prasugrel are superior to clopidogrel in acute coronary syndrome (ACS) patients treated with percutaneous coronary intervention (PCI). Whether this benefit extends to a patient population with chronic coronary syndromes (CCS) is unclear.

Aims

We sought to compare the safety and efficacy of prasugrel and ticagrelor versus clopidogrel in patients undergoing PCI for CCS.

Methods

Consecutive patients undergoing PCI for CCS at a tertiary centre between 2014 and 2019 who were discharged on prasugrel or ticagrelor were compared with those on clopidogrel. The primary endpoint was the composite of death and myocardial infarction (MI), with secondary outcomes including rates of bleeding, stroke, and target vessel revascularisation at 1 year.

Results

Overall, 11,508 patients were included in the study (ticagrelor/prasugrel n=2,860 [24.9%], clopidogrel n=8,648 [75.1%]) with an increasing frequency of potent P2Y₁₂ inhibitor use over the study period (p_trend<0.001). Clopidogrel was used more frequently in patients with multimorbid risk factors, whereas anatomical or procedural complexity was associated with ticagrelor/prasugrel use (left main PCI, bifurcation PCI, number of lesions, rotational atherectomy). No difference in the incidence of death or MI was noted across the groups (ticagrelor/prasugrel vs clopidogrel: 2.7% vs 3.1%, adjusted hazard ratio [adjHR] 0.86, 95% confidence interval [CI]: 0.62-1.17; p=0.33) or secondary outcomes including bleeding (adjHR 0.75, 95% CI: 0.46-1.21; p=0.23) on propensity score stratification analysis. Additionally, no difference in the primary outcome was observed across subgroups, including those undergoing complex PCI.

Conclusions

Ticagrelor and prasugrel are increasingly used in patients with CCS undergoing PCI with similar 1-year efficacy and safety when compared to clopidogrel. Whether use of these agents can be beneficial in patients undergoing PCI for CCS with a high thrombotic and low bleeding risk warrants further study.

Project description:BackgroundPrior Studies have suggested better outcomes in smokers compared with nonsmokers receiving clopidogrel ("smoker's paradox"). The impact of a more intensive clopidogrel regimen on ischemic and bleeding risks in smokers with acute coronary syndromes requiring percutaneous coronary interventions remains unclear.Methods and resultsWe analyzed 17 263 acute coronary syndrome patients undergoing percutaneous coronary intervention from the CURRENT-OASIS 7 (Clopidogrel and Aspirin Optimal Dose Usage to Reduce Recurrent Events-Seventh Organization to Assess Strategies in Ischemic Symptoms) trial, which compared double-dose (600 mg day 1;150 mg days 2-7; then 75 mg daily) versus standard-dose (300 mg day 1; then 75 mg daily) clopidogrel in acute coronary syndrome patients. The primary outcome was cardiovascular death, myocardial infarction, or stroke at 30 days. Interactions between treatment allocation and smoking status (current smokers versus nonsmokers) were evaluated. Overall, 6394 patients (37.0%) were current smokers. For the comparison of double- versus standard-dose clopidogrel, there were significant interactions in smokers and nonsmokers for the primary outcome (P=0.031) and major bleeding (P=0.002). Double- versus standard-dose clopidogrel reduced the primary outcome among smokers by 34% (hazard ratio [HR] 0.66, 95% confidence interval [CI], 0.50-0.87, P=0.003), whereas in nonsmokers, there was no apparent benefit (HR 0.96, 95% CI, 0.80-1.14, P=0.61). For major bleeding, there was no difference between the groups in smokers (HR 0.77, 95% CI, 0.48-1.24, P=0.28), whereas in nonsmokers, the double-dose clopidogrel regimen increased bleeding (HR 1.89, 95% CI, 1.37-2.60, P<0.0001). Double-dose clopidogrel reduced the incidence of definite stent thrombosis in smokers (HR 0.41, 95% CI, 0.24-0.71) and nonsmokers (HR 0.63, 95% CI, 0.42-0.93; P for interaction=0.19).ConclusionsIn smokers, a double-dose clopidogrel regimen reduced major cardiovascular events and stent thrombosis after percutaneous coronary intervention, with no increase in major bleeding. This suggests that clopidogrel dosing in patients with acute coronary syndromes should be personalized, taking into consideration both ischemic and bleeding risk.Clinical trial registrationURL: https://www.clinicaltrials.gov.

Project description:ImportanceGuidelines currently recommend ticagrelor over clopidogrel for patients with acute coronary syndrome (ACS) based on randomized clinical trial data in which ticagrelor reduced major adverse coronary events (MACE) vs clopidogrel but increased bleeding and dyspnea.ObjectiveTo compare the risk of MACE with ticagrelor vs clopidogrel in patients with ACS treated with percutaneous coronary intervention (PCI), to compare major bleeding and dyspnea, and to evaluate the association between P2Y12 inhibitor adherence and MACE.Design, setting, and participantsPopulation-based cohort study using data of patients discharged alive after PCI for ACS from the Alberta Provincial Project for Outcome Assessment in Coronary Heart Disease registry from April 1, 2012, to March 31, 2016, with follow-up to 1 year. Analysis began April 2018.ExposuresOutpatient prescription for ticagrelor or clopidogrel within 31 days after PCI. Adherence was defined as a medication refill adherence value of 80% or higher.Main outcomes and measuresMajor adverse coronary events, a composite of all-cause death, hospitalization for ACS, unplanned coronary revascularization, or stent thrombosis within 365 days after index PCI. Secondary outcomes included hospitalization for major bleeding and emergency department visit for dyspnea.ResultsOf 11 185 individuals who underwent PCI, the median (interquartile range) age was 61 (54-71) years, and 2760 (24.7%) were women. Ticagrelor users (4076 [36.4%]) were generally younger and had fewer cardiac and noncardiac comorbidities than clopidogrel users. Ticagrelor was not associated with lower risk of MACE (adjusted hazard ratio [aHR], 0.97; 95% CI, 0.85-1.10); however, it was associated with an increased risk of major bleeding (aHR, 1.51; 95% CI, 1.29-1.78) and dyspnea (aHR, 1.98; 95% CI, 1.47-2.65). A total of 3328 ticagrelor users (81.6%) were adherent during the study vs 5256 of clopidogrel users (73.9%) (P < .001; χ2 = 86.4). In the full cohort, adherence was associated with a lower MACE risk (aHR, 0.79; 95% CI, 0.69-0.90 for adherence of ≥80% vs <80%). Differences in other secondary outcomes were not statistically significant. Sensitivity and subgroup analyses were consistent with primary analyses.Conclusions and relevanceIn this population-based cohort study of patients with ACS who underwent PCI, outpatient use of ticagrelor was not associated with a statistically significant reduction in MACE vs clopidogrel; however, it was associated with more major bleeding and dyspnea.
