Because the functional interaction between the LV and arterial systems, termed ventricular-arterial coupling, is recognized as a key determinant of LV performance, the objective of the present study was to assess the impact of uncomplicated HT without LVH on LV performance using simultaneously echocardiography and carotid tonometry. LV maximal power (PmaxVG), cardiac power output (CPO), LV efficiency (CPO/PmaxVG), input aortic and output LV elastance (Ea and Ees) were assessed in 20 normotensive control subjects (NT) and 10 patients with untreated HT...
