Heart failure

Saturday, October 30th, 2010

Inability of the heart to assume its function of pump and propulsion of blood to meet the metabolic needs of the organization. Heart failure is the result of most cardiac pathologies, it is common and serious, because its mortality is estimated at 50% at 5 years.

Etiologies:
Heart failure (or ventricular) may be secondary to left:

  • Hypertension by chronic increase of afterload with left ventricular hypertrophy
  • A valvular (narrowing or aortic insufficiency or mitral)
  • Ischemic heart disease (reduction or stoppage of blood flow in one or more arteries of the heart),
  • Hypertensive cardiomyopathy, toxic, or deficiency (beri beri)
  • Obstructive cardiomyopathy
  • Myocarditis (myocarditis, inflammatory rheumatic or Chagas disease, common in South America)
  • Arrhythmias,
  • Profound anemia
  • Hyperthyroidism
  • Ischemic by coronary atherosclerosis

Heart failure (or ventricular) is right most often follows:

  • Left heart failure + + +
  • Pulmonary hypertension, itself caused by a lung disease (chronic bronchitis, emphysema, pulmonary embolism)
  • CHD
  • Mitral stenosis
  • Chronic lung disease

Chronic heart failure:
Often a consequence of hypertension in the small or large circulation, during which the heart muscle to pump against the increased pressure in the vessels. The ventricle must provide more work. (more…)
