Congestive Heart Failure: Cause and Treatment
Congestive heart failure is caused by the hearts inability to eject sufficient blood to feed the organs of the body. Consequently fluid builds up in the lungs causing difficulty breathing.
After being diagnosed by a physician treatment is usually begun by increasing rest, proper diet, drugs such as diuretics, vasodilators, ACE inhibitors, beta blockers and digitalis. Each drug performs differently. Their functions include expanding the blood vessels and decreasing resistance by the ACE inhibitors and vasodilators. Beta blockers improve the function of the left ventricle. Diuretics relieve the body of excess fluid and sodium and digitalis strengthens the pumping action of the heart.
