Coffee Consumption, Serum Copeptin, and Selected Echocardiographic Parameters in Patients with ADPKD: A Cross-Sectional Study

Background/Objectives: Coffee consumption has been suggested to influence arginine vasopressin-related pathways and cardiovascular function. However, its relationships with serum copeptin and cardiac parameters in patients with autosomal dominant polycystic kidney disease (ADPKD) remain unclear. This study aimed to investigate the association between habitual coffee consumption and serum copeptin concentrations and selected echocardiographic parameters in patients with ADPKD.
