What is the role of lungs in causing CAD,coronary artery disease leading to bypass surgery?

I think lungs too may be culprits in causing CAD.Is not it?

We can say that. The level of oxygen is easily tested in the blood, either by a finger sensor which uses 2 wavelengths of light, or a more accurate blood gas which requires a sample of blood. If the oxygen level in the blood is too low, all the major organs will start to be affected, but the heart is one of the last. The first to usually indicate problems is the brain which will start producing hallucinations and memory loss etc, followed by black out. The heart will happily be pumping with no problems during this time. If you could somehow get the oxygen level low enough to starve the heart, it would destroy heart tissue(muscle), not create artery disease.

Thanks.Oxygen supply to blood is by lungs alone. Can  we say that inadequate supply of oxygen will not cause anomaly to blood?

Everything in the body is related, we could say that somehow a sore leg can be linked to the brain. CAD is definitely not caused by lung problems.

The Lungs only perform gas exchange and don't affect the arteries.
