How effective is heart bypass surgery?

The bypasses are about 50% likely to remain open up to 10 years after the operation.

The heart bypass surgery has many benefits, for patients with serious cardiovascular disease. The surgery is only half the battle because the disease process still goes on despite the bypass. To improve their chances, patients must follow special treatments that help stabilize the heart disease.

The benefits of bypass surgery

The bypass surgery can save the life of the patient having a heart attack or with a high risk of having one. Heart bypass surgery improves survival for patients with:

  • coronary artery disease
  • left ventricular dysfunction
  • heart failure
  • chest pain.

Coronary heart disease affects over 10 million people in the U.S.  Each year, more than half a million patients die from coronary heart disease in the United States. Coronary bypass surgery is highly effective in eliminating or reducing discomfort with serious cardiovascular diseases and can lower the risk of heart attacks; patients can remain symptom-free for about 10-15 years.
