What is the pre-cursor to most heart diseases and how does it occur?

Atheroma - damage in endothelium, usually by high blood pressure, white blood cells macrophages & lipids and fat clump together to form fatty streaks, theses build up to form fibrous plaques that partially block lumen, restricts flow & incr pressure

1 of 5

What can atheromas lead to?

Aneurysms & Thrombosis and eventually Myocardinal Infarction

2 of 5

What happens in a aneurysm?

The weakended endothelium caused by the plaque, and the increase in pressure pushes inner layers through out layer forming aneurysm, if this bursts can cause haemorrhage

3 of 5

What is Thrombosis?

Thrombosis is caused by atheromas, the already partially blocked lumen becomes fully blocked by blood clot, embolism (mobile blood clot) can get blocked in atheroma. This blocks cardiac cells from recieving oxygen. 'coronary thrombosis'

4 of 5

What is a Myocardinal Infarction?

When cardiac cells recieve no oxygen because of blocked coronary arterys, the cells cannot respire and die. This is a 'heart attack' Depending on where the blockage was, it can either mean death (early in coronary artery) or can recover (only one v)
