Презентация на тему Radiation diagnosis of acute and chronic heart failure

(from several minutes to several hours). It appears in

the form of pulmonary edema, cardiac asthma and cardiogenic shock. The main causes of acute heart failure are myocardial infarction, rupture of the walls of the left ventricle, acute failure of the aortic and mitral valves.

even years). Causes of chronic heart failure include diseases such as heart disease, hypertension, chronic respiratory failure, prolonged anemia.

alveolar pulmonary edema, interstitial lung edema, basal pleural effusion, or venous congestion in the lungs. In some patients, especially the elderly, it is possible to identify the expansion of the heart. The presence of cardiomegaly indicates a serious heart disease, but the determination of the size of the heart by chest radiograph is not entirely informative, since sometimes they can be normal even in patients with proven heart failure.
