Brief Summary:
The study aims at evaluating the morphological changes of plaque estimated by optical coherence tomography (OCT) and Factors Influencing Plaque Healing after Drug-Coated Balloon (DCB) for de Novo Coronary Lesions.

Condition or disease
Coronary Artery Disease

Detailed Description:
Percutaneous coronary intervention with a drug-eluting stent (DES) is the most common mode of revascularization for coronary artery disease. However, their efficacy is limited by in-stent restenosis and stent thrombosis. Drug-coated balloon (DCB) deliver an anti-proliferative drug into the vessel wall and leave nothing behind, which is a promising technique in the treatment of coronary artery disease. Previous many studies have confirmed that DCB treatment for de Novo coronary lesions is safe and efficient. But, data about morphological changes of plaque and factors influencing plaque healing after DCB for de Novo Coronary Lesions is scarce. The study compares morphological changes of plaques evaluated by OCT between baseline and 1-year follow-up and evaluates factors influencing plaque healing. All the included patient will receive dual antiplatelet therapy (DAPT) for one month followed by clopidogrel treatment.

Official Title: Morphological Changes of Plaque and Factors Influencing Plaque Healing After Drug-Coated Balloon for de Novo Coronary Lesions: A Optical Coherence Tomography Study
Actual Study Start Date : October 1, 2020
Estimated Primary Completion Date : December 31, 2020
Estimated Study Completion Date : January 31, 2021



Primary Outcome Measures :
  1. Major cardiovascular adverse events rate [ Time Frame: 1-year follow-up ]
    In patients treated by DCB, the safety objectives are to evaluate the occurrence of any adverse events in 1 year (re-infarction, re-hospitalization, revascularization by PCI or CABG, cardiac death, stoke, and major bleeding).


Secondary Outcome Measures :
  1. Differences in lesion characteristics evaluated by OCT between baseline and follow-up. [ Time Frame: 1-year follow-up ]
    Lesion characteristics evaluated by OCT include lipid-rich plaque, fibrous plaque, macrophage, cholesterol crystal, microchannels and calcification and minimal lumen area (MLA). The follow-up OCT assessment will be performed 12 months after the treatment procedure.

  2. Differences in lipid-plaque characteristics evaluated by OCT between baseline and follow-up in setting of lipid-plaque. [ Time Frame: 1-year follow-up ]
    The characteristics of lipid-plaque evaluated by OCT include lipid core length, mean lipid arc, max lipid arc, fibrous cap thickness (FCT). The follow-up OCT assessment will be performed 12 months after the treatment procedure.

  3. The incidence of late lumen loss (LLL) at follow-up. [ Time Frame: 1-year follow-up ]
    LLL is defined as MLA at follow-up - MLA at baseline < 0.

  4. Differences in OCT-defined characteristics at baseline according to the presence of late lumen loss (LLL) at follow-up. [ Time Frame: 1-year follow-up ]
    All the patients are divided into two groups according to presence of late lumen loss (LLL) at follow-up. The OCT-defined characteristics include plaque rupture, plaque erosion, lipid-rich plaque, fibrous plaque, macrophage, cholesterol crystal, microchannels and calcification. If the plaque is rich in lipid, the lipid core length, mean lipid arc, max lipid arc, fibrous cap thickness (FCT) will be compared.


Biospecimen Retention:   Samples With DNA
Blood samples (5 ml) were collected before intervention using EDTA tubes at baseline and follow-up. Plasma samples were separated by centrifugation at 1000 g for 10 min and then stored at -80 °C until further analysis.
