What happens during coronary artery disease?

AtherosclerosisClots. The key issue is atherosclerosis: accumulation of white blood cells in the walls of arteries, typically starts in childhood & is primarily driven by lipoproteins (proteins which transport fat in the water outside cells) is dominant human behavior yet is typically ignored for decades because it remains asymptomatic until plaque ruptures release debris, triggers clots & suddenly blocks blood flow.
Blockage. Plaque builds up in the wall of the artery and can cause the artery to get gradually more narrow. If the plaque ruptures the artery can suddenly get completely blocked. The artery blockage can cause chest pain on exertion or even a heart attack resulting in permanent damage to the heart muscle.

Atherosclerosis. CAD is atherosclerosis (known to start ~age 7), an accumulation of white blood cells in the walls of the heart arteries, with artery enlargement (protects blood flow for decades) ; subsequent plaque ruptures with debris+clots downstream + local clots which narrow artery opening producing permanent muscle damage, angina, progressive heart muscle weakness ; ↑ing arrhythmias. Angio;stress tests miss.

Is coronary artery disease inherited?

Sort of. Yes it runs in families so if your parents have it you are more likely to also. This is partly because risk factors such as diabetes are also inherited. It is very complicated however, much more so than hair or eye color for instance because there are so many factors to consider.
Human Dominant. Atherosclerosis, an accumulation of white blood cells in the walls of arteries, typically starts in childhood & is primarily driven by lipoproteins (proteins which transport fat in the water outside cells) is dominant human behavior yet typically ignored for decades because it remains asymptomatic until plaque ruptures releases debris, triggers clots & suddenly block blood flow.
