Exempel på hur man kan använda AFTERLOAD i en mening

• Vasodilation acts to increase cardiac output by decreasing afterload, −one of the four determinants of cardiac output.
• The three curves illustrate that shifts along the same line indicate a change in preload, while shifts from one line to another indicate a change in afterload or contractility.
• AII causes arterial vasoconstriction and hypertension, resulting in an increase in afterload, increasing the resistance against which the heart works.
• Causes of increased afterload that can cause LVH include aortic stenosis, aortic insufficiency and hypertension.
• Milrinone also works to vasodilate which helps alleviate increased pressures (afterload) on the heart, thus improving its pumping action.
• Secondly, the drug is able to open ATP sensitive potassium channels in vascular smooth muscle cells, and the vascular dilatory effects of the drug lead to a decreased preload and afterload, putting less work on the heart.
• Homeometric autoregulation, in the context of the circulatory system, is the heart's ability to increase contractility and restore stroke volume when afterload increases.
• This approach involves adjustments of cardiac preload, afterload, and contractility to balance oxygen delivery with an increased oxygen demand before surgery.
• The Anrep effect is an autoregulation method in which myocardial contractility increases with afterload.
• The restrictively N-terminal truncated cTnT remains functional in the myofilaments and leads to reduced contractile velocity of the ventricular muscle, which extends the rapid ejection phase and results in an increase in stroke volume, especially under increased afterload.
• The acute effects of exercise including increased catecholamines, increased oxygen demand, increased preload and afterload, metabolic derangements, acute kidney injury, dehydration, elevation of troponin, CK, CK-MB, and natriuretic peptides.
