CHD: Coronary Heart Disease
What increases your risk of developing CHD?
Coronary Heart Disease (CHD) is a disease that affects your heart. There are plenty of
lifestyle factors that increase your risk of developing CHD:
1. Poor diet: A diet high in saturated fat or salt increases the risk.
2. Smoking, lack of exercise and excessive alcohol intake: these can all lead to high
blood pressure which can damage the heart and blood vessels, increasing the risk of
CHD.
Atheroma
Atheroma is a fats deposit which forms within the wall of an artery. It begins as streaks of
fats that are accumulations of white blood cells that have taken up low-density lipoproteins
(LDLs). These streaks enlarge to form an irregular patch, or atheromatous plaque. This most
commonly occurs in larger arteries and are made up of deposits of cholesterol, fibres and
dead muscle cells. This then clogs up the lumen of the artery, which results in reduced blood
flow.

Here's a taster:

Aneurysm
Atheroma's that lead to the formation of a thrombus also weaken the artery walls. The
weakened points will swell to form a balloon-like, blood filled structure called an aneurysm.
Aneurysms frequently burst, leading to haemorrhage and therefore loss of blood to the
region of the body served by that artery. A brain aneurysm is known as a cerebrovascular
accident (CVA), or stroke.
Myocardial Infraction
This term is more commonly known as a heart attack.…read more
