"Coronary heart disease (CHD) remains a leading cause of global mortality. While percutaneous coronary intervention (PCI) significantly improves acute survival, patients continue to face substantial residual cardiovascular risk driven by the progression of systemic atherosclerosis. Rigorous management of blood pressure (BP) and low-density lipoprotein cholesterol (LDL-C) is imperative for secondary prevention. However, achieving simultaneous targets (BP \< 130/80 mmHg and LDL-C \< 1.4 mmol/L) in real-world practice is challenging due to clinical inertia and suboptimal patient adherence. Traditional outpatient follow-up is often fragmented and reactive, failing to provide the continuous monitoring required for optimal risk factor control.
The DigiCare-CHD trial serves as a prospective, multicenter, open-label randomized controlled trial designed to enroll 792 patients who have successfully undergone PCI for acute or chronic coronary syndromes. Participants will be randomized 1:1 to either the Digital Remote Management group or the Usual Care group, with a follow-up period of 12 months.
Patients in the intervention arm will utilize a digital remote management platform. This system integrates home monitoring to track BP, lipid profiles, and physical activity. Key features include AI-driven alerts for abnormal values, automated decision support for medication titration (verified by physicians), and targeted health education. The primary endpoint is the rate of dual goal attainment for BP and LDL-C at 12 months. DigiCare-CHD aims to establish a proactive, closed-loop management strategy to effectively reduce residual cardiovascular risk and improve long-term prognosis in the post-PCI population."
