Webb3 aug. 2012 · • Four major determinants of myocardial oxygen demand are afterload, preload, contractility, and heart rate. IABP counterpulsation therapy can have an effect on all these factors. • It decreases afterload directly and affects the other three determinants indirectly as cardiac function improves. WebbOne critical drawback of peripheral ECMO is an increase in left ventricular (LV) afterload which could be counterbalanced by the combination of intra-aortic balloon counter-pulsation (IABP) therapy. We hypothesized that an add-on therapy with IABP could improve outcomes in patients receiving ECMO support. cvs cockrell hill desoto

Visa mer Webb28 apr. 2024 · An increase in the afterload leads to a decrease in the heart's stroke volume and an increase in the end-systolic volume. This also indirectly affects the heart's cardiac output due to a reduction in the stroke volume of the heart. A Frank-Starling curve gives a relationship between stroke volume and left ventricular end-diastolic pressure.
