as judged from the relationship between end-systolic wall stress and ejection phase indices of lv function in the normotensive controls , all hypertensive groups had higher than expected values for lv ejection phase indices , which indicates an increased myocardial contractility secondary to adrenergic stimulation or to a more efficient contractile machinery in the myocardial cells .
