Re: Not enough air to the heart
We have a few med students on this board who can better answer your questions but they are really busy at this time.. hope this helps a bit.
I borrowed this from Google because I didn't want to type it all out. ... this could explain some of what your friend heard from the Doctor.
Oxygen is carried by the blood.
The specialist will probably direct him to get his heart healthy through meds, exercise, diet etc etc..
"Heart disease is caused by narrowing of the coronary arteries that feed the heart. Like any muscle, the heart needs a constant supply of oxygen and nutrients, which are carried to it by the blood in the coronary arteries. When the coronary arteries become narrowed or clogged by cholesterol and fat deposits--a process called atherosclerosis--and cannot supply enough blood to the heart, the result is coronary heart disease (CHD). If not enough oxygen-carrying blood reaches the heart, you may experience chest pain called angina. If the blood supply to a portion of the heart is completely cut off by total blockage of a coronary artery, the result is a heart attack. This is usually due to a sudden closure from a blood clot forming on top of a previous narrowing. "
