SUMMARY OF PRODUCT CHARACTERISTICS

[2] created a short circuit between the right and left atrium including an impeller pump and a miniature oxygenator to achieve RV decompression and afterload reduction. Knowledge of blood pumps operating serially within the circulation remains To clarify the mechanisms of afterload reduction on left ventricular diastolic function, the influence of nitroglycerin upon ventricular diastolic pressure-volume relations was studied in 22 patien Positive pressure ventilation affects preload, afterload and ventricular compliance. The net effect in most situations is a decrease in cardiac output. However, the effect may be beneficial in the context of decompensated heart failure, where the decreased preload and afterload result in a return to a more productive part of the Starling curve. Remarkable reduction in early mortality was achieved over the 12 years reported.

Afterload reduction

A sudden fall in afterload is associated with an immediate increase in stroke volume. If venous return is also increased, a sustained increase in stroke volume occurs. Packer M, Meller J, Gorlin R, Herman MV: Hemodynamic and clinical tachyphylaxis to prazosin-mediated afterload reduction in chronic congestive heart failure. Circulation 59: … 2020-01-03 Because less blood remains in the ventricle after systole, the ventricle does not fill to the same EDV found before the afterload reduction.

2010-02-23 2020-04-30 Decreasing afterload and increasing inotropic both reduce end-systolic volume, which cause the end-diastolic volume to decrease secondarily. Reduced venous pressure decreases capillary pressure and fluid filtration in the lungs (left-sided failure) and systemic tissues (right-sided failure), thereby diminishing the edema.

Abstract. Nifedipine and captopril are potent vasodilators and may be expected to help left ventricular failure by reducing afterload. Nifedipine (20 mg three times a day) and captopril (50 mg three times a day) were added to an optimal regimen of digitalis and diuretics in a double blind crossover trial in 18 cases of dilated cardiomyopathy.

After nitroglycerin, average ventricular systolic pressure declined by 25 mm Hg 1986-04-01 2012-01-31 2020-07-23 Thus, when afterload reduction is combined with inotropic stimulation, a greater increase in cardiac output can be achieved in patients with heart failure. Dobutamine is another effective inotropic agent given by i.v. infusion (2.5-10 mg/kg/minute), also acting on cardiac beta-1 receptors.

2020-06-05 To clarify the mechanisms of afterload reduction on left ventricular diastolic function, the influence of nitroglycerin upon ventricular diastolic pressure-volume relations was studied in 22 patients during catheterization.

J Clin Invest 1979;64: 643-654 2005-12-07 · The reduction in afterload leads to an increased cardiac output and improved tissue perfusion. b) Venous selective vasodilators increase venous capacitance, thus decreasing preload. A small reduction in venous tone can result in a pooling of large amounts of blood. 2021-04-10 · Non-invasive ventilation (NIV) is the delivery of assisted mechanical ventilation to the lungs, without the use of an invasive endotracheal airway. NIV has revolutionised the management of patients with various forms of respiratory failure. It has decreased the need for invasive mechanical ventilation and its attendant complications.
