HEART FAILURE & PULMONARY EDEMA
SIGNS, SYMPTOMS AND TREATMENT
Heart Failure Heart failure is a syndrome in which the heart pumps insufficient oxygenated blood to meet the metabolic needs of the tissues, or can do so only from an elevated filling pressure. Maximal oxygen utilization is thus reduced in proportion to the degree of heart failure Heart failure may be left-sided, in which pulmonary edema is a predominant symptom, or right-sided, often with hepatomegaly and systemic edema. In many instances, both sides of the heart are involved. Exercise intolerance and fatigue are common in all patients Heart failure may also be characterized as systolic and/or diastolic. In systolic heart failure, the left ventricular ejection fraction is reduced. In diastolic heart failure, the left ventricle systolic function typically is preserved, but the altered ventricle compliance results in a high filling pressure. This distinction should be made during the diagnostic evaluation because the two conditions have different prognoses and may respond differently to treatment
SynonymsCongestive heart failure
CHF (congestive heart failure)
Cardiac failure
Pulmonary Edema
Pulmonary edema involves the accumulation of fluid, either protein-rich or protein-poor depending on etiology, into the pulmonary interstitium and, later, the alveoli themselves The earlier stages may be asymptomatic, but exertional breathlessness (dyspnea on exertion) is common, as is orthopnea (breathlessness when lying flat) and paroxysmal nocturnal dysphasia. Later alveolar edema, when severe, can cause right-to-left shunting of venous blood with consequent arterial oxygen desaturation, myocardial depression, and metabolic acidosis The most common cause of acute pulmonary edema is left ventricular failure, although there are many other possible causes Management centers on increase of arterial oxygen content with supplemental oxygen and assisted ventilation, reduction of the pulmonary blood volume using diuretics, vasodilation with medications such as nitroglycerine and morphine, use of continuous positive airway pressure (PAP), judicious use of inotropes, and, very rarely, venesection or rotating tourniquets Severe acute pulmonary edema is a medical emergency and requires immediate resuscitation, stabilization, and hospital admissionPrognosis depends on the cause of pulmonary edema and the underlying condition of cardiopulmonary and renal systems
