Heart Attacks
Hi Docter Burger.

We all know that a heart attack is the result of a norrowed or blocked artery on the muscle of the heart due to cholesterol deposits and/or narrowed blood vessels.

Since we have much smaller arteries in our bodies such as in the eyes, brain, lungs etc, why is only the hearts arteries affected and narrowed.

Maybe a silly question, sorry.

Thanks

The heart has a set amount of arteries. When one artery is blocked, there is no time for collateral arteries to develop, as the blockage results in immediate tissue damage. Lipid deposits affects all small arteries, especially in the eyes and brain. In other parts of the body, the tissue will develop collateral blood flow, bypassing the blockage. In areas where the small arteries that are blocked, like in the eyes, brain and heart, the damage is immediate and devastating.
