Afterload is the pressure that the heart must work against to eject blood during systole (ventricular contraction). Afterload is proportional to the average...

individuals, but increased afterload will hinder the ventricles in ejecting blood, causing reduced stroke volume. Increased afterload may be found in aortic...

against LV volume at multiple time points during a single cardiac cycle. Afterload is the mean tension produced by a chamber of the heart in order to contract...

myocardial contractility increases with afterload. It was experimentally determined that increasing afterload caused a proportional linear increase in...

myocardial oxygen perfusion and indirectly increases cardiac output through afterload reduction. It consists of a cylindrical polyurethane balloon that sits...

systemic vascular resistance results in an increase in afterload. With HOCM, an increase in afterload will hold the obstruction in a more open configuration...

Conduction velocity Preload Afterload Contractility By this model, if myocardial performance changes while preload, afterload, heart rate, and conduction...

This tension is called afterload. When the resistance is increased particularly due to stenotic valve damage the afterload must necessarily increase...

physiology terms for the hemodynamic modulators are preload, contractility and afterload. They deal with (a) the inertial filling forces of blood return into the...

handgrip maneuver increases afterload by squeezing the arterioles and increasing total peripheral resistance. Since increasing afterload will prevent blood from...

cardiac cycle. The main factors that affect the end-systolic volume are afterload and the contractility of the heart. End systolic volume can be used clinically...

resistance. Vasodilation acts to increase cardiac output by decreasing afterload, −one of the four determinants of cardiac output. By expanding available...

Disease processes that can cause LVH include any disease that increases the afterload that the heart has to contract against, and some primary diseases of the...

vascular dilatory effects of the drug lead to a decreased preload and afterload, putting less work on the heart. This drug is in the process of review...

in preload, while shifts from one line to another indicate a change in afterload or contractility. A blood volume increase would cause a shift along the...

output and peripheral resistance, with relatively low blood pressure, the afterload on the heart decreases; this decreases how hard the heart must work to...

administration results in a decrease in total peripheral resistance (afterload) and cardiac venous return (preload). All of the physiological effects...

resistance to blood flow through systemic arterioles, which decreases afterload (decreases the failing heart's workload) and reduces the amount of mitral...

Milrinone also works to vasodilate which helps alleviate increased pressures (afterload) on the heart, thus improving its pumping action. While it has been used...
