Integration of BNP and blood glucose for identifying coronary flow reserve impairment: A cardiovascular-kidney-metabolic perspective.

ABSTRACT: Cardiovascular-kidney-metabolic (CKM) syndrome may predispose patients to coronary microvascular dysfunction (CMD) through systemic microvascular injury. We investigated the association between CKM risk factors and CMD, focusing on the diagnostic performance of accessible biomarkers. In this exploratory analysis, we retrospectively analyzed 65 patients who underwent invasive coronary physiological assessment with thermodilution-derived coronary flow reserve (CFR) and index of microcirculatory resistance (IMR). Clinical variables included casual blood glucose, B-type natriuretic peptide (BNP), and the urine albumin-to-creatinine ratio (ACR), along with echocardiographic indices of diastolic function. Among the 65 patients, 20 (31 %) had impaired CFR. BNP (AUC = 0.74; 95 % confidence interva
