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.

Fonarow is a member of the writing group for the ACC/AHA guidelines on management of heart failure. They recommend as a risk reduction strategy identification of patients with stage A pre-heart failure and addressing their risk factors: treating their hypertension and lipid disorders, gaining control over metabolic syndrome, discouraging heavy alcohol intake, and encouraging smoking cessation and regular exercise (J Am Coll Cardiol.
In the prospective observational Physicians' Health Study of nearly 21,000 men, adherence to six modifiable healthy lifestyle factors was associated with an incremental stepwise reduction in lifetime risk of developing heart failure. The six lifestyle factors--a forerunner of the AHAs Life's Simple 7--were maintaining a normal body weight, stopping smoking, getting exercise, drinking alcohol in moderation, consuming breakfast cereals, and eating fruits and vegetables.
Defining heart failure as a breakdown of the heart due to overwhelming burden, Professor Amam Mbakwem, a consultant cardiologist, Lagos University Teaching Hospital (LUTH) reeled out the risk factors of heart disease.

While there is no regulatory requirement at present to stipulate that heart failure should be assessed in trials looking at the cardiovascular safety of T2DM treatments, recording such information is something that the STENO-2 investigators would recommend.
While metformin and comprehensive lifestyle management remain the foundational therapy recommendations, Sy said after metformin, the treatment approach is to consider the presence or absence of atherosclerotic cardiovascular disease, heart failure or chronic kidney disease.
It happens within 30 seconds of bending over and is usually a sign of worsening heart failure. The heart is not able to compensate for the fluid shifts and extra pressure placed on the abdomen when you bend over.
Advanced heart failure therapies include intravenous medications, implantable cardioverter-defibrillators, pacemakers, and ventricular assist devices that help the heart pump more blood.
