Document Summary
A clinical syndrome, which results when the left, right or both ventricles fail to pump sufficient blood to meet the body"s metabolic needs. Not enough blood supply to circulation to sustain organs to meet requirements of blood supply to body. Excessive preload (volume overload: regurgitation (valve incompetence) (l, r) flows back. Excessive demand (anaemia, hyperthyroidism) (r: with too much blood and volume overload, not enough hemoglobin, hypervolemia (r, too much volume in blood, renal dysfunction. Due to mi does not contract part of heart: prevalence increase in heart failure due to ageing population and people surviving mi but still left with deficit in myocardium: leads to. Heart failure, any problems in any areas can lead to heart failure. Inflammation/obstruction in muscle in heart: disease, autoimmune disease: arrhythmias, consequence of hf. Right atrium anterior and posterior vena cava tricuspid rv pumped out pulmonary artery (deoxygenated blood) 0 lungs left atrium, ventricle to aorta.
