Heart Failure

 

(cardiac insufficiency), a combination of disorders caused primarily by a reduction in cardiac contractility. Heart failure may occur if the heart is overstrained as a result of arterial hypertension or heart disease or if the blood supply to the heart is interrupted (myocardial infarction). Toxic influences, such as those produced during Graves’ disease, and myocarditis may also cause heart failure.

Heart failure is accompanied by congestion, because the weakened cardiac muscle cannot handle circulation. Left ventricular heart failure results in pulmonary congestion accompanied by dyspnea, cyanosis, and hemoptysis, whereas right ventricular heart failure results in passive congestion of systemic circulation marked by the development of edemas and the enlargement of the liver. Heart failure results in hypoxia of the organs and tissues, acidosis, and other metabolic disorders. Acute heart failure usually occurs in the left ventricle and is manifested by an attack of cardiac asthma.

Heart failure is treated with cardiac glycosides, diuretics, and antiarrhythmics. Surgery, for example, the implantation of a pacemaker, may be performed in certain cases.

In the present study, surgical treatment was applied to 30% of patients, and it was indicated in the presence of serious cardiac insufficiency that was refractory to clinical treatment and younger patients without associated complications.
This cardiac insufficiency means less blood is being pumped with every beat of the heart.

Hawthorn has been studied in Europe, where one multicenter observational study of 1,011 patients with New York Heart Association stage II cardiac insufficiency were treated with a proprietary standardized formulation (extract WS 1442) for 24 weeks.
The authors asked practicing cardiologists what they regarded as the 10 leading medical advances of their lifetimes; the scientists named such advances as cardiac surgery, drug treatment of hypertension, and medical treatment of cardiac insufficiency. Comroe and Dripps then traced the scientific ancestry of each of these discoveries and found that 40 percent of the studies leading to the advances originated from work in a different, seemingly unrelated field of research.
These patients had severe underlying conditions (i.e., cardiac insufficiency, pneumonia, or systemic lupus erythematosis), and the extent to which RAEs contributed to their deaths was undetermined.
Wednesday's operation, involving some 20 doctors led by Nobuyoshi Shimizu, was delayed as the woman was also suffering from cardiac insufficiency and the density of carbon dioxide in her blood had risen.
Symptoms of cardiac insufficiency or anginal syndrome may be present even at rest.
Secondly, other concurrent illnesses can affect the clinical picture of asthma, and cardiac insufficiency, tumours of the airways and other chronic bronchial diseases, among others, can cause wheezing respiratory difficulties of a kind that resemble asthma symptoms.
Daily body weight, the follow-up of the intake/discharge ratio, fluid uptake, and associated complications are important to prevent cardiac insufficiency. Vital signs should be monitored daily; for example, tachycardia may be a sign of cardiac insufficiency.
