Studies have shown that only 3-4% of the patients come back in one year’s time with recurrent symptoms. Also 40% patients are symptom free for almost 10 years. The symptoms are usually of less intensity compared to before surgery. Also, the recurrence of chest pain is more in women than men.

When patients are in need of redo bypass surgery, the success rate is lower than for first operation.

Coronary Artery Bypass Surgery is a major surgical procedure and it carries some risks and complications. These complications are higher in patients who are heavy smokers or if they have a major problem with this other vital organs such as kidneys or lungs or have reduced blood supply to the brain.

Infection and bleeding are examples of risks and complications any surgery may present.

Some of these complications may be uncommon. Complications after surgery include-

  • Ankle swelling
  • Heart Attack
  • Stroke
  • Emboli
  • Arrhythmias
  • Vein graft occlusion
  • Kidney failure or temporary shutdown
  • Death
  • Stress and Depression - could be long-term problem.

Some patients may lose some of their cognitive ability,especially older women, however most will regain it within six to 12 months. Usually bypass surgery will not cause dementia however it may worsen this condition if is is present prior to surgery.

The risk of death from CABG is approx 1%. The main reason of death is heart attacks occurring during or immediately after surgery. Heart attacks occurs in about 5% of the patients.

Neurological complications are minimal and occurs more in women than men, especially elder. Incidence of stroke is about 1-2 %.

Long term studies show that exercise reduces mortality rate by 20%.

I had CABG 13 years ago (at age 69) and it resulted in a stroke that left me with hemiplegia. Now, my angina is returning, but I'm treating it with Seanol - which so far (2 months)has been successful. Rowland
