Verapamil: prevention and treatment of cardio-renal syndromes in diabetic hypertensive patients?

Patients with diabetes mellitus (DM) often present other chronic comorbidities including arterial hypertension (AH), chronic kidney disease (CKD), ischemic heart disease (IHD) and heart failure with preserved ejection fraction (HFpEF). The frequent association of the latter conditions is considered part of the spectrum of cardio-renal syndromes (CRS), a group of disorders of the heart and kidneys whereby acute or chronic dysfunction in one organ may induce acute or chronic dysfunction of the other. Verapamil is a non-dihydropyridine calcium channel blocker (CCB) widely used in the treatment of hypertension, chronic stable angina, secondary prevention of reinfarction, paroxysmal supra-ventricular tachycardia and for rate control in atrial fibrillation/flutter. In addition to its antihypertensive and anti-ischemic actions verapamil exerts favorable effects also on glycemic control, proteinuric diabetic nephropathy, left ventricular diastolic dysfunction and sympathetic nervous system overactivity which may potentially benefit patients with DM and CRS. In this narrative review, we summarize the current evidence on the potential role of verapamil in the prevention and treatment of CRS in diabetic hypertensive patients. [ABSTRACT FROM AUTHOR]
