title: [Clinical aspects of acute heart failure].
abstract: A review summarizing recent findings on the causes of the development, pathogenesis, diagnosis and treatment of acute cardiac failure. It is a condition when the heart is unable to pump blood in amounts needed for the metabolic activity of tissues. It may be the first manifestation of disease or acute deterioration of chronic heart failure. The most frequent causes of acute left-sided failure include acute myocardial infarction, arterial hypertension, valvular defects, myocarditis, toxic damage or metabolic myocardial disorders. In right-sided failure pulmonary embolism, extensive affections of the lungs and pleura, right ventricular infarction and affection of the pericardium predominate. The clinical picture of cardiac failure is due to a combination fo the basic disease, evoking causes, signs of an inadequate minute volume, transudation of fluids into the interstitium and the presence of compensating mechanisms. The diagnosis of cardiac failure is based on an analysis of subjective and objective clinical symptoms and other auxiliary examinations such as X-ray examination of the chest, electrocardiogram, echocardiography, examination of blood gases and other laboratory examinations. In right-sided insufficiency the examination is supplemented by pulmonary scintigraphy, possibly by catheterization of the right heart and pulmonary angiography. As to the differential diagnosis, we must differentiate from acute cardiac failure, asthma bronchiale, spontaneous pneumothorax, dyspnoea in neuroasthenic patients, non-cardiac pulmonary oedema. Treatment of cardiac failure involves lifestyle and dietary provisions, medicamentous treatment which has undergone great changes in recent years. Cardiac failure is controlled by reduction of the cardiac filling pressure and support of the efficiency of the cardiac pump (Inotropy) and control of excessive fluid and salt retention. Decisive for the subsequent development of the disease is diagnosis of the basic cardiac or non-cardiac disease and its aimed treatment. In uncontrolled cardiac failure mechanical support of cardiac activity and transplantation of the heart are options.
