Web5 nov. 2008 · An elevated cardiac output with clinical heart failure is associated with several diseases including chronic anaemia, systemic arterio-venous fistulae, sepsis, hypercapnia and hyperthyroidism. The underlying primary physiological problem is of reduced systemic vascular resistance either due to arterio-venous shunting or peripheral vasodilatation. Web22 mei 2024 · Following decades of study, it is now generally agreed that the characteristic gradient in hypertrophic obstructive cardiomyopathy (HOCM) is a dynamic subaortic pressure gradient due to LVOT obstruction from systolic anterior motion of the mitral valve (SAM). 4, 5 These LVOT gradients, when high, are accompanied by exercise …

In most studies of patients with cirrhosis, the heart mass has been found to be within the normal range. 11, 12 However, some have reported an increased left … Hyperdynamic circulation is abnormally increased circulatory volume. Systemic vasodilation and the associated decrease in peripheral vascular resistance results in decreased pulmonary capillary wedge pressure and decreased blood pressure, presenting usually with a collapsing pulse, but sometimes a bounding pulse. In effort to compensate the heart will increase cardiac output and heart rate, which accounts for the increased pulse pressure and sinus tachycardia. The condition …
