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...

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

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

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

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...

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

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

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

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...

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

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...

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

cardiac muscle in which it has to contract while experiencing an excessive afterload. Pressure overload may affect any of the four chambers of the heart, though...

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...

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

peripheral vessels, respectively, which reduces peripheral resistance and afterload, though not as potent as the dihydropyridine (DHP) calcium channel blockers...

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

blood shift, and the increasing resistance to left ventricular ejection (afterload) by rising blood pressure. Other changes commonly measured in the electrocardiogram...

step-wise approach, with the physiologic goal of optimizing cardiac preload, afterload, and contractility. It includes giving early antibiotics. EGDT also involves...

natriuresis. This consequently may lead to a reduction in preload and afterload, thereby alleviating cardiac workload and improving left ventricular function...

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...

acute MR is normotensive, vasodilators may be of use to decrease the afterload seen by the left ventricle and thereby decrease the regurgitant fraction...

Vasodilators are increased (such as nitric oxide and carbon monoxide) reducing afterload with compensatory increase in cardiac output, mixed venous oxygen saturation...
