Cardiac failure - Causes

What are the causes of cardiac failure?

There are various causes of heart failure.

  • One of the most frequent causes is a coronary heart disease with calcification of the coronary arteries. The arteries that supply the heart muscle are contracted and an undersupply results.  The muscles constantly lose their capacity.
  • High blood pressure (hypertension) is the second main cause. The constant overstress wears out the muscles to a certain extent and causes them lose some of their pumping performance. 

Further causes of heart failure

  • Cardiac arrhythmias
  • Heart muscle inflammation
  • Heart valve defects
  • Fluid retention in the heart sac (pericardial effusion)
  • Heart muscle diseases caused by abuse of alcohol, drugs or medicine
  • Genetic factors
  • Diabetes mellitus 
  • Thyroid dysfunctions
  • Pulmonary emphysema
  • COPD

A rarer disease is the so-called stress cardiomyopathy; also known as the broken-heart syndrome. After a great shock, respectively after a traumatic experience, a potentially life threatening heart weakness sets in. A permanent heart failure mostly does not occur. It is more common that the function of the pumping organ normalizes again. Neither life expectancy, nor quality of life are reduced.
