Comparison of the Incidence of Major Cardiovascular Events Between the Combination of Percutaneous Intervention and Optimal Drug Therapy and the Optimal Drug Therapy Alone in Patients With Chronic Coronary Syndrome (PIVOT)

15 maggio 2026 aggiornato da: Jung-Kyu Han, Seoul National University Hospital

Percutaneous Intervention Versus Optimal Medical Therapy in Chronic Coronary Syndrome (PIVOT) Trial

Comparison of the incidence of major cardiovascular events between the combination of percutaneous intervention and optimal drug therapy and the optimal drug therapy alone in patients with chronic coronary syndrome.

  • Main RCT (Randomized Clinical Trial): Patients with chronic coronary syndrome enrolled in the study will be randomized in a 1:1 ratio to either 1) PCI(Percutaneous Coronary Intervention) plus optimal medical therapy or 2) optimal medical therapy alone, with clinical outcomes assessed during follow-up. (2,301 participants)
  • Nested RCT: An embedded randomized supplementary study was conducted on a subset (220 participants) of the total subjects.

In patients who have decided to use beta-blockers for the control of angina, additional 1:1 randomization evaluates the efficacy of carvedilol sustained-release (SR) and immediate-release (IR) formulations. Both formulations are targeted for use up to the maximal tolerated dose, taking into account patient symptoms.

Descrizione dettagliata

Background:

In patients with chronic coronary syndrome (CCS), the role of percutaneous coronary intervention (PCI) beyond symptom relief - particularly in preventing future major cardiovascular events - remains an area of active debate. Landmark trials such as COURAGE and ISCHEMIA raised questions about the incremental benefit of PCI over optimal medical therapy (OMT) alone; however, both trials allowed crossover from the medical arm to PCI, and included periprocedural myocardial infarction (MI) in their primary endpoints, which may have diluted the observed treatment effects. Moreover, since those trials were conducted, both PCI techniques and pharmacological therapies have advanced substantially. Imaging-guided PCI using intravascular ultrasound (IVUS) or optical coherence tomography (OCT) has been shown to reduce adverse cardiac events, and lipid-lowering strategies have been further strengthened by the addition of ezetimibe and PCSK9 inhibitors. Against this background, a rigorous re-evaluation of PCI's role in CCS, using contemporary devices and a more conservative definition of clinically driven revascularization, is warranted.

Study Design:

The PIVOT trial is a multicenter, prospective, open-label, randomized controlled trial conducted at multiple sites in South Korea. Eligible patients with CCS who have a functionally or anatomically significant coronary stenosis confirmed by coronary angiography are randomized 1:1 to either (1) PCI plus optimal medical therapy or (2) optimal medical therapy alone. Randomization is stratified by participating center and sex using a web-based system managed independently by the Medical Research Collaborating Center (MRCC).

Main RCT - Intervention:

In the PCI arm, the target lesion(s) are treated with drug-eluting stent(s) according to each site's standard practice. Imaging-guided PCI with IVUS or OCT is strongly recommended and is mandatory for complex PCI cases. The BioFreedom ULTRA stent (polymer-free, Biolimus A9-coated) is used preferentially; other approved drug-eluting stents may be used when clinically indicated. Following PCI, dual antiplatelet therapy is maintained for 6 months per guideline recommendation, with adjustments permissible based on individual bleeding and ischemic risk. Both arms receive guideline-directed optimal medical therapy, including intensive lipid-lowering treatment (LDL-C target <55 mg/dL), antiplatelet agents, and anti-anginal medications as indicated. Lifestyle interventions (smoking cessation, weight management, dietary modification, and physical activity) are also recommended.

Primary Endpoint (Main RCT):

Patient-oriented composite outcome (POCO): a composite of cardiovascular death, non-fatal myocardial infarction, or clinically driven revascularization at 2 years after completion of enrollment. Periprocedural MI is excluded from the primary endpoint. The trial is powered for superiority (one-sided α = 0.025, power = 90%), assuming a 2-year POCO rate of 12.0% in the OMT arm and 8.5% in the PCI arm. A total of 2,301 participants are required.

Follow-up:

Participants are followed at 6 months, 1, 2, 3, 4, and 5 years after enrollment (±90 days). Clinical outcomes, vital signs, laboratory tests, concomitant medications, and angina-related quality of life (Seattle Angina Questionnaire-7, SAQ-7) are assessed at every visit. Long-term follow-up up to 5 years after the last enrolled patient is planned to evaluate durability of treatment effects.

Nested RCT - Design and Rationale:

An embedded, independently randomized substudy (Nested RCT) is conducted within the PIVOT trial. Among participants in the main trial for whom beta-blocker therapy is deemed clinically appropriate - based on pre-specified criteria including heart rate control needs, history of prior MI, concurrent hypertension, tachyarrhythmia, or intolerance to calcium channel blockers - an additional 1:1 randomization is performed to compare carvedilol sustained-release (SR) versus immediate-release (IR) formulations. This substudy addresses the evidence gap regarding whether the two formulations are clinically equivalent in terms of angina symptom control in CCS patients, as head-to-head randomized data are currently lacking despite both being widely prescribed.

Nested RCT - Intervention:

Participants assigned to the SR arm receive carvedilol SR (Dilatrend SR; starting dose 32 mg once daily, up-titrated to 64 mg or 128 mg as tolerated). Participants assigned to the IR arm receive carvedilol IR (Dilatrend; starting dose 12.5 mg twice daily, up-titrated to 25 mg twice daily or 50 mg twice daily as tolerated). Both formulations are titrated to the maximal tolerated dose with a resting heart rate target of 55-60 bpm. Medication adherence is assessed by pill count at 6 and 12 months.

Primary Endpoint (Nested RCT):

Change in SAQ-7 Summary score from baseline to 12 months. Non-inferiority of carvedilol SR versus IR is concluded if the lower bound of the 95% confidence interval for the between-group difference exceeds -5 points, analyzed by ANCOVA adjusting for baseline SAQ-7 score. A total of 220 participants are required (one-sided α = 0.025, power = 80%, non-inferiority margin Δ = 5 points).

Statistical Analysis:

For the main RCT, the primary endpoint is analyzed using the Kaplan-Meier method with a stratified log-rank test in the intention-to-treat (ITT) population. Secondary time-to-event endpoints are analyzed using the cumulative incidence function with a Fine and Gray model, treating death as a competing risk. The Nested RCT primary endpoint is analyzed by ANCOVA in both the ITT and per-protocol (PP) populations.

Lasso di tempo
Change in Seattle Angina Questionnaire-7 (SAQ-7) Summary Score from Baseline to 12 Months (for Nested RCT)
Lasso di tempo: One year after registration
This outcome applies to the Nested RCT substudy only (n=220), in which participants eligible for beta-blocker therapy are independently randomized 1:1 to carvedilol SR or IR, regardless of their main trial allocation. The SAQ-7 is a 7-item validated questionnaire assessing angina-related health status across three domains: physical limitation, angina frequency, and quality of life. Scores range from 0 to 100, with higher scores indicating fewer symptoms and better quality of life. The SAQ-7 Summary score is calculated as the mean of the three domain scores.
One year after registration
Number of Participants with Patient-oriented composite outcome (POCO), defined as the composite of cardiovascular death, non-fatal myocardial infarction (MI), or clinically driven revascularization
Lasso di tempo: 2nd year and 5th year since registration was complete

This outcome applies to the main RCT (n=2,301). POCO is a composite of three components: (1) cardiovascular death; (2) non-fatal myocardial infarction, excluding periprocedural MI; and (3) clinically driven revascularization. The first occurrence of any component is counted as the primary event per participant.

Clinically driven revascularization is defined as revascularization of a coronary segment with diameter stenosis ≥50% by quantitative coronary angiography, accompanied by at least one of the following: ischemic ECG(Electrocardiogram) changes at rest; typical ischemic symptoms refractory to medical therapy; unstable angina; positive invasive physiologic test (FFR(Fractional Flow Reserve) ≤0.80 or iFR (Instantaneous Wave-Free Ratio) ≤0.89); or angiographic progression with diameter stenosis ≥70% by quantitative coronary angiography regardless of other criteria.
