Heart failure causes

Cardiomyopathy. Cardiomyopathy, or diseased heart muscle, may reach a point at which the heart can no longer function. It arises from a combination of factors, including hypertension, arrhythmias, and valve disease. Other problems, such as congestive heart failure, cause the interrelated heart—lung system to break down. Because the heart can no longer adequately pump, duid builds up in the lungs and other areas. 

Some chemical exposures may be hepatic enzyme inducers/inhibitors, altering the effects of drugs like warfarin. Some foods such as mono-amines, will cause reactions in patients given MAOIs grapefruit juice may interact with terfenadine and some other drugs. New diseases may cause problems heart failure causing reduced liver blood flow can reduce the metabolism of drugs like warfarin.

Heart failure causes Kerley s B lines (edema of interlobular septa), which appear as thin, horizontal reticular fines in the costophrenic angles. At higher pressures, alveolar edema and pleural effusions appear in the pleural space or as blunting of the costophrenic angles. Pericardial effusions also may appear as a large heart, but because it usually occurs rapidly, there is no evidence of pulmonary venous congestion.

Digoxin increases the force of cardiac contraction in the failing heart. Thi.s benefit has often Ireen doubted in patients with chronic heart failure in sinus rhythm, but recent clinical trials have shown that digoxin can reduce the symptoms of heart failure in patients who arc already receiving diuretics and ACE inhibitors. Digoxin is particulurly indicated in heart failure caused by atrial fibrillation (Chapter 17).
