Selective Heart Rate Reduction Improves Metabolic Syndrome–related Left Ventricular Diastolic Dysfunction
Abstract
Enhanced heart rate observed in metabolic syndrome (MS) contributes to the deterioration of left ventricular (LV) function via impaired LV filling and relaxation, increased myocardial O2 consumption, and reduced coronary perfusion. However, whether heart rate reduction (HRR) opposes LV dysfunction observed in MS is unknown.
