Introduction: The disease I am researching on is the Coronary Heart Disease, because it is the leading cause of death in Australia. The coronary heart disease is also known as Ischaemic Heart Disease, Coronary Artery Disease (CAD) or CHD (not to be confused with Congenital Heart Defection, it is a defection that can be lifelong and it is present at birth) it is one branch and also the most common form of the cardiovascular disease (CVD).
Data: In each year, the coronary heart disease claims around 20,000 lives, that’s an eighth of death in Australia each year, so it roughly takes one Australian in 30 minutes (27 minutes per one death on coronary heart disease calculated in 2015). And about 12% of Australian aged from 30 to 65 are told by doctors …show more content…
(Data recorded in 2016) Coronary Heart Disease is the most common cause of a heart attack.
Plaque: Coronary Heart Disease happens when little arteries around your heart are getting clogged up by a fatty material called ‘plaque’. Coronary arteries are small pipes supplying your heart with blood rich in nutrients and oxygen. Plaque builds up around the wall of the artery, which creates a narrower space for blood to pass through, this process is called atherosclerosis, which can start when you are still young.
Different types of plaque and effects on the circulatory system: There are two types of plaques that are present in the coronary arteries, stable plaque and unstable plaque. Stable plaque is not harmful but if it blocks the artery too much, blood couldn’t be delivered to meet the inquiry of the heart. That will then develop angina, which can show symptoms of chest pain and patients may also experience heavy weight been placed on the heart. If angina is ignored, it might develop to heart attack. Unstable plaque contains a lot more fat than the stable plaque. Unstable plaque generally doesn’t severely block the arteries, but it can develop cracks on the wall of the artery. After the cracks occurs, the components called platelets will clot up the cracks which blocks the
