Today, more than half of patients operated on the heart has more than 70 years. What path when we know that in the 70's, these patients represented only 3.6% of patients in cardiac surgery ... And the results are excellent!

 

Large advances in cardiac surgery

Cardiac surgery continues to make progress and it changes the lives of many patients, especially that of those who had a heart attack and who can provide a bypass clogged coronary arteries.

In this difficult operation, it bypasses the blocked part of the heart arteries with vein grafts: the heart receives oxygenated blood again and may re-run in good conditions.

Coronary Artery Bypass Graft Surgery (CABG)

What is coronary artery bypass graft (CABG) surgery?

According to the American Heart Association 427,000 coronary artery bypass graft (CABG) surgeries were performed in the United States in 2004, making it one of the most commonly performed major operations.

CABG surgery is advised for selected groups of patients with significant narrowings and blockages of the heart arteries (coronary artery disease). CABG surgery creates new routes around narrowed and blocked arteries, allowing sufficient blood flow to deliver oxygen and nutrients to the heart muscle.

How is coronary artery disease diagnosed?

The resting electrocardiogram (EKG) is a recording of the electrical activity of the heart, and can demonstrate signs of oxygen starvation of the heart (ischemia) or heart attack. Often, the resting EKG is normal in patients with coronary artery disease and angina. Exercise treadmill tests are useful screening tests for patients with a moderate likelihood of significant coronary artery disease (CAD) and a normal resting EKG. These stress tests are about 60 to 70% accurate in diagnosing significant CAD.

If the stress tests do not reveal the diagnosis, greater accuracy can be achieved by adding a nuclear agent (thallium or Cardiolite) intravenously during stress tests. Addition of thallium allows nuclear imaging of the blood flow to different regions of the heart, using an external camera. An area of the heart with reduced blood flow during exercise, but normal blood flow at rest, signifies significant artery narrowing in that region.

How is coronary artery disease (CAD) treated?

Medicines used to treat angina reduce the heart muscle demand for oxygen in order to compensate for the reduced blood supply. Three commonly used classes of drugs are the nitrates, beta blockers and calcium blockers. Nitroglycerin (Nitro-Bid) is an example of a nitrate. Examples of beta blockers include propranolol (Inderal) and atenolol (Tenormin). Examples of calcium blockers include nicardipine (Cardene) and nifedipine (Procardia, Adalat). Unstable angina is also treated with aspirin and the intravenous blood thinner heparin. Aspirin prevents clumping of platelets, while heparin prevents blood clotting on the surface of plaques in a critically narrowed artery. When patients continue to have angina despite maximum medications, or when significant ischemia still occurs with exercise testing, coronary arteriography is usually indicated. Data collected during coronary arteriography help doctors decide whether the patient should be considered for percutaneous coronary intervention, or percutaneous transluminal angioplasty (PTCA), whereby a small balloon is used to inflate the blockage. Angioplasty (PTCA) is usually followed by placement of a stent or coronary artery bypass graft surgery (CABG) to increase coronary artery blood flow.

Angioplasty can produce excellent results in carefully selected patients. Under x-ray guidance, a wire is advanced from the groin to the coronary artery. A small catheter with a balloon at the end is threaded over the wire to reach the narrowed segment. The balloon is then inflated to push the artery open, and a steel mesh stent is generally inserted.

Heart surgery at any age

The age and should be considered a risk factor and needs to be a good motivation to stay fit longer! In general, age is no longer a limitation for many operations and, in addition to the heart, hip operations and other prosthetic joints experiencing the same evolution.

This decline in age management should be put down as the progress of general anesthesia than that of operative techniques. The development of surgery without exta Circulation (CPB), known as beating heart, and has represented a major advance in operative mortality dividing by two.

In conclusion, the only real limits to the indications for surgery are not really age but the general condition and smoking significantly slowing the healing process. Certainly, age is no longer what it was and that's great!
