OSA: obstructive sleep apnea, BP: blood pressure, ABPM: ambulatory blood pressure monitoring, CPAP: continuous positive airway pressure, LVH: left ventricular hypertrophy, ARB: angiotensin II receptor blocker, SGLT2i: Sodium-glucose cotransporter 2 inhibitors, ARNI: angiotensin receptor-neprilysin inhibitor, CCB: calcium channel blocker, GIP/GLP-1 RA: glucose-dependent insulinotropic polypeptide receptor and glucagon-like peptide-1 receptor agonist. This evidence concerns the gene GCG and obstructive sleep apnea syndrome.
