Basal dilation

웹Vasodilators are medications that open (dilate) blood vessels. They affect the muscles in the walls of the arteries and veins, preventing the muscles from tightening and the walls from narrowing. As a result, blood flows more easily through the vessels. The heart doesn't have to pump as hard, reducing blood pressure. 웹11시간 전 · Ventricular dilation may be an early marker of disease in patients with dilated cardiomyopathy20 or undergoing follow-up for treatment with cardiotoxic therapy.21 Increasing LV cavity size portends worsening prognosis with adverse remodelling after myocardial infarction.22 Conversely a reduction in LV size is associated with improved outcome …
