Association between the triglyceride/high-density lipoprotein cholesterol ratio and isolated nocturnal hypertension.

Isolated nocturnal hypertension is associated with increased cardiovascular risk, but its relationship with insulin resistance remains uncertain. In this study of 1623 patients undergoing ambulatory blood pressure monitoring, the triglyceride-to-high-density lipoprotein cholesterol (TG/HDL-C) ratio was higher in patients with isolated nocturnal hypertension than in normotensive individuals; however, this association was no longer significant after adjustment for cardiometabolic risk factors. These findings suggest that insulin resistance reflects the adverse metabolic profile accompanying isolated nocturnal hypertension rather than an independent determinant of this phenotype.
