Impact of gender on adrenergic-induced cardiac dilatation and systolic dysfunction in spontaneously hypertensive rats

Abstract

Left ventricular hypertrophy (LVH) is more frequently associated with LV dilatation and systolic chamber dysfunction in males than in females. The mechanisms of this effect are uncertain. As excessive adrenergic stimulation may be responsible for LV dilatation and systolic chamber dysfunction in hypertension, in my dissertation I aimed to assess whether gender determines the adverse effects on LV chamber remodeling following 6 months of daily β-adrenergic receptor (AR) stimulation (isoproterenol [ISO]
