Prevention & Treatments of Coronary Heart Disease

Extracts from this document...

Introduction

Prevention & Treatments of Coronary Heart Disease Coronary heart disease is caused by the narrowing of the coronary arteries, which feed the heart. All muscles need a constant supply of oxygen and nutrients, therefore so does the heart since it to is a muscle. The heart gets these nutrients and oxygen by the blood carried to it by the coronary arteries. However, when the coronary arteries get clogged by fat deposits and cholesterol, the coronary arteries become narrower, this process is called atherosclerosis, and therefore not enough blood gets supplied to the heart and results in coronary heart disease (CHD). There are different forms of CHD which can occur. If the heart does not receive enough oxygenised blood, the victim can experience extreme chest pains, this is called angina. When a large portion of the coronary artery is blocked, possibly by a blood clot, and the supply to part of the heart is cut off, can result in a heart attack; heart attacks cause sudden severe chest pains and can be fatal. Another form of CHD is heart failure which is cause by, again, the blockage of the coronary artery. ...read more.

Middle

Since from this we can concur that hypertension increases in risk with age, by reducing causes of hypertension at an early age, we can minimise the risk of coronary heart disease developing. In recent research, it has been discovered that people who take a small dosage of aspirin daily, are less likely to develop heart disease. This is because of the function of aspirin in the body. Aspirin was found to thin the blood, by reducing the adhesiveness or "stickiness" of the platelets in the blood so that they so don't clot as well. What this does is, it stops there from being large clots so if an artery or blood vessel is damaged, normally the platelets would form a fairly large clot causing the blood vessel to narrow down and forcing the heart to pump harder. With aspirin, less platelets stick together, so the clot formed is not as big and so it does not make the blood vessel too narrow. Also sometimes, blockages in the coronary artery and other blood vessels are caused by platelets, and with aspirin, there is less chance of these blood clots occurring. ...read more.

Conclusion

This procedure is only recommended for patients with one or more of the following symptoms: Blockage (stenosis) of one or more coronary arteries, angina not well controlled with medication, angina that disrupts daily activities, occurs at rest (i.e., without exercise or exertion), or recurs after heart attack. The last procedure is called coronary bypass surgery. This major operation involves opening the chest wall and inserting a graft or an alternate passage (usually taken from a vein in the leg) into the coronary artery that is blocked. By placing a graft in the diseased artery, blood can then bypasses the obstruction. If more than one coronary artery is blocked, multiple grafts can be inserted. As a last resort, if nothing else has worked, a complete heart transplant it done, but this is a very difficult procedure and so is only done if absolutely necessary. Even though all of these treatments are available, it is preferred by doctors, that firstly measures to prevent CHD from occurring should be practiced, and then, if someone does manage to get CHD, then a life style change should be done before attempting to have surgery, because in some cases it is possible to over come the problem simply by doing the basic prevention methods, but just to a slightly higher level.

    In other cases high blood pressure increases risk factors but this is only true when atherosclerosis and arteriosclerosis are already are both present in the coronary arteries. High blood pressure may damage the atheromas present or even the artery wall; this can cause clotting and lead to further health complications (source 1 & 9)

    Any arterial blockage can deprive tissue of oxygen- damaging or killing it. (Advanced Biology and www.bhf.org.uk) Blood pressure is the pressure of the blood in the arteries. A certain amount of pressure is needed to keep the blood flowing. High blood pressure develops if the walls of the larger arteries

    In 1994 researchers looked at 21,000 twins born in Sweden between 1886 and 1925. They found 2367 pairs in which at least one twin had died of coronary heart disease. If coronary disease were governed only by genes, then every time one identical twin died of it, the other would have to as they both have the same genes.
