Summary

Based on a multi-center randomized controlled study, this research aims to evaluate the efficacy and safety of interventional therapy supported by the CorVad percutaneous left ventricular assist system (Micro-axial Flow Pump） for patients with complex coronary heart disease (CHD) complicated by ischemic left ventricular systolic dysfunction. Through a prospective, multi-center, open-label 1:1 randomized controlled trial, a total of 452 patients with severe ischemic systolic dysfunction and complex coronary lesions were enrolled. The study compared the 12-month incidence of Major Adverse Cardiovascular and Cerebrovascular Events (MACCE) between patients who received interventional therapy supported by the CorVad percutaneous left ventricular assist system in addition to the most appropriate medical therapy and those who only received the most appropriate medical therapy. This was done to test whether the interventional therapy supported by the CorVad percutaneous left ventricular assist system can improve the prognosis of patients with severe ischemic systolic dysfunction and complex coronary lesions.

Conditions

  • Coronary Artery Disease (CAD)

Interventions

DEVICE

Microaxial pump-supported PCI

Use CorVad left ventricular assist system (micro-axial Flow Pump) to assist PCI in complex coronary artery disease with ischemic LV dysfunction patients

DRUG

Optimal medical therapy (OMT)

Guideline-directed OMT will be determined by the heart failure team at each center. OMT may include antiplatelet therapy, lipid-lowering therapy, antianginal therapy, evidence-based heart failure therapy, blood pressure and glycemic control, lifestyle management, and other therapies appropriate to the patient's diagnosis and comorbidities. Evidence-based heart failure therapy includes angiotensin converting enzyme inhibitor or angiotensin receptor blocker +/- neprilysin inhibitor, beta-blocker, mineralocorticoid receptor antagonist, sodium-glucose co-transporter 2 inhibitor, and vericiguat.
