It may also improve arterial oxygenation by reducing pulmonary vascular congestion DIURETICS.
Mild heart failure responds well to diuretics such as furosemide,
Dose - 10 to 40 mg, repeated at 3- to 4-hour intervals if necessary.
It reduces pulmonary capillary pressure reduces dyspnea.
Decreased LVDV↓ LV wall tension - ↓ myocardial oxygen requirements and may lead to improvement of contractility and augmentation of the ejection fraction, stroke volume, and cardiac output.
The reduction of elevated left ventricular filling pressure may also enhance myocardial oxygen delivery by diminishing the impedance to coronary perfusion attributable to elevated ventricular wall tension.
