[메디칼업저버 신형주 기자] An answer to the appropriate stent spade treatment for diabetic patients with coronary artery bifurcation lesions has been found.

In branch hospitals, lesions have occurred in locations including the part where the main branches of the coronary arteries branch, and the risk of restenosis or similar has been reported during stent treatment depending on the procedure.

In particular, diabetes is considered a significant factor in various complications including stent restenosis.

The Academia is focusing their attention on finding an appropriate stent procedure to apply to coronary artery bifurcation lesions in diabetic patients.

Accordingly, a research team led by Professor Soon-Jun Hong and Professor Jeong-Jun Cha from the Department of Cardiovascular Medicine at Korea University Anam Hospital conducted a multi-center study in Korea to investigate the clinical outcomes of the stent placement method for bifurcation lesions in 906 diabetic patients among 2648 patients treated for coronary artery lesions with second generation stents.

Through this, the research team presented a customized stent treatment method suitable for diabetic patients.

Stent treatment for coronary artery lesions can be divided into two methods.

There is a method of treating only the main blood vessel using only one stent, and a method of placing stents in the main blood vessel and the side branches.

In the case of diabetes, it is known that the method of treating only the main blood vessel is better, but depending on the treatment situation, there are cases where stents have to be placed in the main blood vessel and the side branches .

Various procedures and methods have been developed and used in clinical practice.

The research team investigated the prognosis 5 years after treatment for patients who applied 6 types of stent treatment methods (Simple crossover, one-stent with balloon SB, T or TAP, V, squeeze, culotte) and other treatment methods and is mainly used in this regard. study, comparative analysis.

As a result of the study, when treating branch lesions in diabetic patients using second generation stents, when stents were placed in the main blood vessel and side branches, and when specific treatment methods were used (T, V), it was found that failure target lesions (heart-related death), target vascular myocardial infarction, and target lesion revascularization) 3.59 times higher.

In other methods apart from this, it was found that there was no difference in the clinical course between the method of treating only the main blood vessel and the method of treating the side branches.

Professor Hong Soon-joon said, “Through this study, we found a tailored treatment method for diabetic patients, which has been developed with various stents for complex lesions in coronary artery treatment, but which is increasing’ continuously.”

Professor Jeongjun Cha also said, “We will strive to provide better treatment for patients suffering from coronary artery disease through dedicated treatment for diabetic patients.”

Meanwhile, this research paper, ‘Bifurcation strategies using second-generation drug-eluting stents on clinical outcomes in diabetic patients’, was published in the latest issue of the international journal ‘Frontiers in Cardiovascular Medicine’ and was supported by the Branch Lesion Research Group. from the Korean Society of Interventional Cardiovascular Interventions, he went on
