About

This trial is a multi-center, randomized, double-blind, placebo, parallel controlled study. Objectively evaluates the curative effect of Huoxin Pills (concentrated pills) intervention on improving the prognosis of patients with coronary heart disease after drug-coated balloon implantation from a functional point of view. Huoxin Pill(concentrated pills), a traditional Chinese medicine, has been prescribed widely in the treatment of coronary heart disease, angina pectoris, and other diseases.440 patients were selected and followed up for one year. The quantitative blood flow score of the target vessel, late lumen loss, MACE incidence, and safety index were observed at 12 months.

Full description

Percutaneous coronary intervention (PCI) is currently the main treatment for coronary heart disease. Drug-coated balloon (DCB) is an emerging interventional therapy technology. DCB can effectively reduce the incidence of vascular restenosis and cardiovascular composite event endpoints after PCI. However, the incidence of target lesion failure and major adverse cardiac event (MACE) of DCB in the treatment of primary coronary artery disease within one year after surgery can also reach more than 10%. Therefore, how to reduce vascular restenosis after DCB and other related cardiovascular composite endpoint events through the combination of DCB and drug therapy is a potential development direction of existing DCB therapy.

The research results of Chinese scholars have shown that the traditional Chinese medicine of replenishing qi and activating blood circulation can significantly reduce the restenosis rate after PCI, the recurrence rate of angina pectoris and the incidence of cardiovascular composite endpoint in three and six months after PCI.

It has significant clinical efficacy in improving the symptoms and prognosis of patients with coronary heart disease such as angina pectoris. In addition, basic research has further shown that Huoxin Pill (concentrated pill) can significantly reduce the degree and scope of myocardial ischemia and has the effects of dilating coronary artery and improving microcirculation.

Quantitative flow fraction (QFR) technology is the new method with the most sufficient clinical evidence in recent years, and can rapidly calculate the coronary stenosis-related lesions and severity of the diseased vessels in real time during the operation. Therefore, in this study, the QFR technology was used to evaluate the postoperative efficacy of DCB and the combination of Huoxin Pill (concentrated pill).

This trial is a multi-center, randomized, double-blind, placebo, parallel controlled study. Objectively evaluates the curative effect of Huoxin Pills (concentrated pills) intervention on improving the prognosis of patients with coronary heart disease after drug-coated balloon implantation from a functional point of view. Huoxin Pill(concentrated pills), a traditional Chinese medicine, has been prescribed widely in the treatment of coronary heart disease, angina pectoris, and other diseases.440 patients were selected and followed up for one year. The quantitative blood flow score of the target vessel, late lumen loss, MACE incidence, and safety index were observed at 12 months.
