DCB Under the Guidance of OCT in STEMI

March 22, 2023 updated by: Henan Institute of Cardiovascular Epidemiology

A Prospective, Multi-center, Randomized, Parallel Controlled Clinical Trial of Drug Coated Balloon Under the Guidance of OCT in the Treatment of Acute ST-segment Elevation Myocardial Infarction

Acute ST segment elevation myocardial infarction (STEMI) has a high disability mortality rate, and timely reperfusion treatment can significantly reduce the mortality of patients. Emergency PCI is the preferred strategy for STEMI treatment recommended by domestic and international guidelines. The long-term existence of stents can never completely avoid the formation of thrombosis in the stents and affect the relaxation and contraction of criminal blood vessels. Drug coated balloon provides a new concept and technology of interventional therapy for coronary artery disease in the form of "intervention without implantation". Through balloon dilation of local blood vessels to release anti proliferative drugs to coronary artery wall and inhibit intimal hyperplasia, it can not only treat serious coronary artery disease, improve coronary blood supply and vascular function, but also not leave permanent implants in the blood vessels; The main pathogenesis of STEMI is thrombosis based on the rupture or erosion of coronary atheromatous plaque. In terms of pathophysiological mechanism, drug coated balloons are also suitable for STEMI patients without obvious thrombosis or severe dissection after full pretreatment. The two-dimensional lumen images obtained by traditional coronary angiography can not directly reflect the vessel wall, so we can not evaluate the actual size of the vessel, plaque characteristics and the effect of intervention through coronary angiography; Optical coherence tomography (OCT) uses near-infrared scanning to produce high-resolution tissue microscopic images with a resolution of up to 10 μ m. It can clearly observe the three-layer structure of coronary artery, find abnormal intima structure, and more clearly identify thrombosis, dissection, plaque erosion or collapse in coronary artery, providing more valuable information for optimizing interventional treatment. Therefore, the application of drug coated balloon under the guidance of OCT in STEMI can provide a more accurate and optimized diagnosis and treatment scheme for STEMI patients.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No
