Treat-to-Target or High-Intensity Statin in Patients With Coronary Artery Disease: A Randomized Clinical Trial.

ABSTRACT:

Importance

In patients with coronary artery disease, some guidelines recommend initial statin treatment with high-intensity statins to achieve at least a 50% reduction in low-density lipoprotein cholesterol (LDL-C). An alternative approach is to begin with moderate-intensity statins and titrate to a specific LDL-C goal. These alternatives have not been compared head-to-head in a clinical trial involving patients with known coronary artery disease.

Objective

To assess whether a treat-to-target strategy is noninferior to a strategy of high-intensity statins for long-term clinical outcomes in patients with coronary artery disease.

Design, setting, and participants

A randomized, multicenter, noninferiority trial in patients with a coronary disease diagnosis treated at 12 centers in South Korea (enrollment: September 9, 2016, through November 27, 2019; final follow-up: October 26, 2022).

Interventions

Patients were randomly assigned to receive either the LDL-C target strategy, with an LDL-C level between 50 and 70 mg/dL as the target, or high-intensity statin treatment, which consisted of rosuvastatin, 20 mg, or atorvastatin, 40 mg.

Main outcomes and measures

Primary end point was a 3-year composite of death, myocardial infarction, stroke, or coronary revascularization with a noninferiority margin of 3.0 percentage points.

Results

Among 4400 patients, 4341 patients (98.7%) completed the trial (mean [SD] age, 65.1 [9.9] years; 1228 females [27.9%]). In the treat-to-target group (n = 2200), which had 6449 person-years of follow-up, moderate-intensity and high-intensity dosing were used in 43% and 54%, respectively. The mean (SD) LDL-C level for 3 years was 69.1 (17.8) mg/dL in the treat-to-target group and 68.4 (20.1) mg/dL in the high-intensity statin group (n = 2200) (P = .21, compared with the treat-to-target group). The primary end point occurred in 177 patients (8.1%) in the treat-to-target group and 190 patients (8.7%) in the high-intensity statin group (absolute difference, -0.6 percentage points [upper boundary of the 1-sided 97.5% CI, 1.1 percentage points]; P < .001 for noninferiority).

Conclusions and relevance

Among patients with coronary artery disease, a treat-to-target LDL-C strategy of 50 to 70 mg/dL as the goal was noninferior to a high-intensity statin therapy for the 3-year composite of death, myocardial infarction, stroke, or coronary revascularization. These findings provide additional evidence supporting the suitability of a treat-to-target strategy that may allow a tailored approach with consideration for individual variability in drug response to statin therapy.

Project description:ImportanceCoronary plaques that are prone to rupture and cause adverse cardiac events are characterized by large plaque burden, large lipid content, and thin fibrous caps. Statins can halt the progression of coronary atherosclerosis; however, the effect of the proprotein convertase subtilisin kexin type 9 inhibitor alirocumab added to statin therapy on plaque burden and composition remains largely unknown.ObjectiveTo determine the effects of alirocumab on coronary atherosclerosis using serial multimodality intracoronary imaging in patients with acute myocardial infarction.Design, setting, and participantsThe PACMAN-AMI double-blind, placebo-controlled, randomized clinical trial (enrollment: May 9, 2017, through October 7, 2020; final follow-up: October 13, 2021) enrolled 300 patients undergoing percutaneous coronary intervention for acute myocardial infarction at 9 academic European hospitals.InterventionsPatients were randomized to receive biweekly subcutaneous alirocumab (150 mg; n = 148) or placebo (n = 152), initiated less than 24 hours after urgent percutaneous coronary intervention of the culprit lesion, for 52 weeks in addition to high-intensity statin therapy (rosuvastatin, 20 mg).Main outcomes and measuresIntravascular ultrasonography (IVUS), near-infrared spectroscopy, and optical coherence tomography were serially performed in the 2 non-infarct-related coronary arteries at baseline and after 52 weeks. The primary efficacy end point was the change in IVUS-derived percent atheroma volume from baseline to week 52. Two powered secondary end points were changes in near-infrared spectroscopy-derived maximum lipid core burden index within 4 mm (higher values indicating greater lipid content) and optical coherence tomography-derived minimal fibrous cap thickness (smaller values indicating thin-capped, vulnerable plaques) from baseline to week 52.ResultsAmong 300 randomized patients (mean [SD] age, 58.5 [9.7] years; 56 [18.7%] women; mean [SD] low-density lipoprotein cholesterol level, 152.4 [33.8] mg/dL), 265 (88.3%) underwent serial IVUS imaging in 537 arteries. At 52 weeks, mean change in percent atheroma volume was -2.13% with alirocumab vs -0.92% with placebo (difference, -1.21% [95% CI, -1.78% to -0.65%], P < .001). Mean change in maximum lipid core burden index within 4 mm was -79.42 with alirocumab vs -37.60 with placebo (difference, -41.24 [95% CI, -70.71 to -11.77]; P = .006). Mean change in minimal fibrous cap thickness was 62.67 μm with alirocumab vs 33.19 μm with placebo (difference, 29.65 μm [95% CI, 11.75-47.55]; P = .001). Adverse events occurred in 70.7% of patients treated with alirocumab vs 72.8% of patients receiving placebo.Conclusions and relevanceAmong patients with acute myocardial infarction, the addition of subcutaneous biweekly alirocumab, compared with placebo, to high-intensity statin therapy resulted in significantly greater coronary plaque regression in non-infarct-related arteries after 52 weeks. Further research is needed to understand whether alirocumab improves clinical outcomes in this population.Trial registrationClinicalTrials.gov Identifier: NCT03067844.

Project description:ImportanceHigh-intensity statin is strongly recommended in patients at very high risk (VHR) of atherosclerotic cardiovascular disease (ASCVD). However, concerns about statin-associated adverse effects result in underuse of this strategy in practice.ObjectiveTo evaluate the outcomes of a moderate-intensity statin with ezetimibe combination in VHR and non-VHR patients with ASCVD.Design, setting, and participantsThis was a post hoc analysis of the Randomized Comparison of Efficacy and Safety of Lipid Lowering With Statin Monotherapy vs Statin/Ezetimibe Combination for High-Risk Cardiovascular Disease (RACING) open-label, multicenter, randomized clinical trial. The study was conducted from February 2017 to December 2018 at 26 centers in Korea. Study participants included patients with documented ASCVD. Data were analyzed from April to June 2022.InterventionsPatients were randomly assigned to moderate-intensity statin with ezetimibe (rosuvastatin, 10 mg, with ezetimibe, 10 mg) or high-intensity statin monotherapy (rosuvastatin, 20 mg). Patients at VHR for ASCVD were defined according to the 2018 American Heart Association/American College of Cardiology guidelines.Main outcomes and measuresThe primary end point was the 3-year outcome of cardiovascular death, coronary or peripheral revascularization, hospitalization of cardiovascular events, or nonfatal stroke.ResultsA total of 3780 patients (mean [SD] age, 64 [10] years; 2826 male [75%]) in the RACING trial, 1511 (40.0%) were categorized as VHR, which was associated with a greater occurrence of the primary end point (hazard ratio [HR], 1.42; 95% CI, 1.15-1.75). There was no significant difference in the primary end point between those who received combination therapy and high-intensity statin monotherapy among patients with VHR disease (11.2% vs 11.7%; HR, 0.96; 95% CI, 0.71-1.30) and non-VHR disease (7.7% vs 8.7%; HR, 0.88; 95% CI, 0.66-1.18). The median low-density lipoprotein cholesterol (LDL-C) level was significantly lower in the combination therapy group than in the high-intensity statin group (VHR, 1 year: 57 [47-71] mg/dL vs 65 [53-78] mg/dL; non-VHR, 1 year: 58 mg/dL vs 68 mg/dL; P < .001). Furthermore, in both the VHR and non-VHR groups, combination therapy was associated with a significantly greater mean change in LDL-C level (VHR, 1 year: -19.1 mg/dL vs -10.1 mg/dL; 2 years: -22.3 mg/dL vs -13.0 mg/dL; 3 years: -18.8 mg/dL vs -9.7 mg/dL; non-VHR, 1 year: -23.7 mg/dL vs -12.5 mg/dL; 2 years: -25.2 mg/dL vs -15.1 mg/dL; 3 years: -23.5 mg/dL vs -12.6 mg/dL; all P < .001) and proportion of patients with LDL-C level less than 70 mg/dL (VHR, 1 year: 73% vs 58%; non-VHR, 1 year: 72% vs 53%; P < .001). Discontinuation or dose reduction of the lipid-lowering drug due to intolerance occurred less frequently in the combination therapy group (VHR, 4.6% vs 7.7%; P = .02; non-VHR, 5.0% vs 8.7%; P = .001).Conclusions and relevanceResults suggest that the outcomes of ezetimibe combination observed in the RACING trial were consistent among patients at VHR of ASCVD.Trial registrationClinicalTrials.gov Identifier: NCT03044665.
