Сравнение DCB и DES для тяжелой кальцификации de Novo поражения у пожилых пациентов с ХСН

Краткое описание

The goal of this clinical trial was to compare the effectiveness of drug balloons versus drug-coated stents in calcified lesions in elderly coronary artery disease. The main question it aims to answer is whether the application of DCB is non-inferior to DES for in situ large vessel calcified lesions in the elderly coronary arteries. And to develop a method to precisely identify the nature and extent of calcified lesions and to rationalize the choice of pretreatment.
