PCI With Guideline-Directed Medical Therapy for HFpEF Patients With Ischemic Cardiomyopathy

Sponsor: Nanjing First Hospital, Nanjing Medical University

View on ClinicalTrials.gov

Summary

To evaluate whether percutaneous coronary intervention (PCI) with contemporary drug-eluting stents (DES) combined with guideline-directed medical therapy (GDMT), compared to GDMT alone, reduces the time to first occurrence of major adverse cardiovascular events (MACE) through 12 months in patients with ischemic cardiomyopathy and a left-ventricular ejection fraction (LVEF) ≤40%. MACE is a composite of cardiovascular \[CV\] death, spontaneous myocardial infarction (MI), any unplanned revascularization, heart failure (HF)-related rehospitalization, heart transplantation, requirement of device implantation (e.g., valvular treatment, pacemaker, or left ventricular assist device \[LVAD\]), or requirement of intravenous medications due to worsening heart failure in outpatients.

PROCEDURE

Percutaneous coronary intervention

PCI will be performed according to standard techniques. Use of a contemporary, FDA/CE-approved drug-eluting stent is mandatory.

DRUG

Guideline-directed medical therapy

GDMT optimization follows a structured titration algorithm: Week 0: introducing angiotensin-converting enzyme inhibitor (ACEi)/ angiotensin II receptor blocker (ARB) or angiotensin receptor-neprilysin inhibitors (ARNI) and beta-blockers. Week 1: adding mineralocorticoid receptor antagonist (MRA) and sodium-glucose cotransporter 2 inhibitors (SGLT2i). Adjust every 2-4 weeks to reach target or tolerable dose unless symptomatic hypotension (systolic blood pressure \[SBP\] \< 90 mmHg) or estimated glomerular filtration rate (eGFR) drop \> 30 % or serum potassium \>5.2 mmol/L.

Inclusion Criteria: * Both male and female subjects aged ≥18 years at screening. * Documented LVEF ≤40% assessed by echocardiography, or cardiac magnetic resonance imaging (CMR), or ventriculography within 90 days prior to randomization. * Symptomatic heart failure (NYHA Functional Class II, III, or ambulatory class IV) * Angiographically proven CAD with at least one lesion (50\~89% stenosis by visual estimate in a major epicardial vessel ≥2.5mm in diameter, or ≥50% left main stenosis, both requiring a QFR≤0.8) considered amenable to PCI with DES by an interventional cardiologist. * On stable, optimally titrated GDMT for at least 2 weeks prior to randomization, as tolerated. This includes, at a minimum, a beta-blocker and a renin-angiotensin-aldosterone system inhibitor (ACEi/ARB/ARNI) at maximal tolerated doses. * The subject, or their legal guardian, has a clear understanding of the trial's design and procedures, provides written informed consent, and able to comply with follow-up. Exclusion Criteria: * Acute coronary syndrome (ACS) within 30 days requiring urgent/emergent revascularization. * Non-cardiac life expectancy \<1 year at screening (e.g., malignancy, advanced liver disease). * Coronary anatomy unsuitable for PCI or requiring urgent surgical revascularization (e.g., diameter stenosis ≥90%, diameter stenosis \<90% but QFR\>0.8, complex multi-vessel disease deemed better suited for coronary artery bypass grafting \[CABG\] by Heart Team). * Prior CABG. * HF due to specific cardiomyopathies, including restrictive/infiltrative cardiomyopathy, active myocarditis, constrictive pericarditis, severe valvular stenosis, or hypertrophic obstructive cardiomyopathy (HOCM). * Contraindication to GDMT medications, dual antiplatelet therapy, or iodinated contrast. * Pregnancy, lactation, or women of childbearing potential not using effective contraception. A negative urine pregnancy test is required at each visit for women of childbearing potential. * Participation in another investigational trial that may interfere with the PCI and GDMT as specified in this protocol. * Any other circumstances that the investigator deems inappropriate for participation, including but not limited to conditions that may jeopardize patient safety, confound data interpretation, or patients unlikely to comply with study procedures.
