Prognostic value of transthoracic coronary flow reserve in medically treated patients with proximal left anterior descending artery stenosis of intermediate severity

摘要

Aims Prognostic value of transthoracic coronary flow reserve (T-CFR) is not established in patients with left anterior descending artery (LAD) stenosis of intermediate severity. Objective is to determine the prognosis value of T-CFR 2 in medically treated patients with angiographically intermediate [50–70% QCA (quantitative coronary angiography)] proximal LAD stenosis.
