Measuring hypertensive cardiovascular risk: the vascular overload concept.

abstract：BACKGROUND:It has been reported that mineralocorticoid receptor antagonist improves the prognosis of chronic heart failure (CHF). Recently, hemoglobin A₁(c) (HbA₁(c)) levels have been reported to be an independent risk factor for mortality in CHF, suggesting the important role of insulin resistance in CHF. We compared ...
