artherosclerosis

Atherosclerosis is the build up of fatty substances on the inner blood vessel lining. This later causes the blood vessel to become clogged up and the fat can detach and block smaller vessels.

Problem:
Smaller blood vessel, especially the coronary arteries, when blocked have large consequences on the BP and transport of oxygen to tissues. A possible solution could be to put a nano-tracer, that circulates the blood vessels and maps out the diameter of the vessels. Any abnormal diameters or changes in it, will be detected and lead to a better diagnosis of heart attack.

The related problem is to develop a nano-tracer, that will do such a thing!

Heart failure

Heart failure is a disease which reduces heart contractility. This in turn reduces the amount of blood transporting nutrients.

Heart failure is caused by: blockages of coronary artery, reduced intracellular calcium and impaired energy production and utilisation. The major effects include: pulmonary or peripheral oedema and excessive heart activity.

Is there a faster way of detecting heart failure? why don't we make a nanobot that will be able to diagnose and detect heart problems? or something linked to the baroreceptors?

Why aren't the causes of heart failure targeted?
