Drug-Eluting Balloon Treatment vs. Guideline-Directed Medical Therapy for the Treatment of Lipid-Rich Plaques

The goal of this clinical trial is to find out whether treating vulnerable plaques in the coronary arteries with a drug-coated balloon can make them less dangerous than using standard medication alone. The study includes adults with acute coronary syndrome (a type of heart problem caused by reduced blood flow in the coronary arteries). The main questions the study aims to answer are: * Does the drug-coated balloon reduce the amount of fat inside the plaque more than medication alone? * Is this treatment safe for patients? Participants will: * Undergo imaging of their coronary arteries during their planned heart procedure (PCI) * Be randomly assigned to receive either a drug-coated balloon treatment or no extra treatment * Undergo a heart scan (CT scan of the coronary arteries) within 2 weeks and again around 9 months after the procedure. * Undergo a second heart catherization 9 months later to examine changes in the plaque.

Effectiveness of Interventional Therapy for Non-Flow-Limiting Vulnerable Plaques

The aim of this clinical trial is to explore the optimal preventative treatment strategy for non-flow-limiting vulnerable plaques. The main question it aims to answer is: Can interventional therapy further improve the outcome of non-flow-limiting vulnerable plaques on top of optimal pharmacologic therapy? Researchers will randomly assign patients who meet the inclusion criteria to preventative intervention plus optimal drug therapy (experimental group) or optimal drug therapy alone (control group). Participants will: Assigned to the control group: optimized drug therapy consisting of lifestyle improvement and intensive drug therapy including high-dose statin or other therapy to achieve target levels (low-density lipoprotein cholesterol \<1.4 mmol/L and decreased by 50% compared to the baseline). Lifestyle improvement and risk factor management included smoking cessation, nutritional optimization, physical activity, compliance with prescribed medications, and control of diabetes and hypertension. Assigned to the experimental group: all non-flow-limiting vulnerable plaques were treated with conventional second-generation drug-eluting stents. After the procedure, participants received dual antiplatelet therapy for about 12 months as well as other medications in the control group.

Ticin Pilot Study: Sirolimus-Eluting Balloon for Stabilization and Regression of Non-Obstructive Coronary Plaques.

The goal of this pilot clinical trial is to evaluate the use of the Selution SLR sirolimus-eluting balloon, in addition to guideline-directed medical therapy (GDMT), for the preventive treatment of non-flow-limiting vulnerable coronary lesions, compared to GDMT alone, in adult patients with multivessel coronary artery disease and a recent acute coronary syndrome (within 90 days). The main research question is: Does the use of the Selution SLR sirolimus-eluting balloon in combination with GDMT reduce the progression and vulnerability of non-flow-limiting vulnerable coronary plaques? Participants will undergo * PCI procedure with baseline IVUS-NIRS assessment * Follow-up coronary angiography at 6 months with IVUS-NIRS assessment * Clinical follow-up at 3, 6, and 24 months after study enrollment
