Is Smoking The Main Cause Of Heart Disease?

Extracts from this document...


Science Y10 Coursework Is Smoking The Main Cause Of Heart Disease...? In this study I will look at what heart disease actually is, how it can be caused through smoking, what can be done to prevent it, what are the major symptoms of heart disease, what are the other main causes and is the government doing enough to help not only prevent smoking but heart disease as well. By Matthew Lee 10B Intro... What is heart disease? Definition: Disorders of the heart can result in decreased blood supply to the heart muscle and result in shortness of breath. These include coronary artery disease, valvular disorders, heart failure www.ecu.edu/cs-dhs/pulmonary/glossary.cfm What I am going to look at... In this study of Heart Disease I am going to look at what heart disease actually is, how it can be caused through smoking, how it can be caused through other methods such as Diet, family genes and of course smoking, the main type of heart disease I will be looking at is CAD or Connery Heart Disease as you can see in the diagram above... Coronary Artery Disease (CAD) Coronary artery disease (CAD) is a condition in which plaque builds up inside the coronary arteries. These arteries supply your heart muscle with oxygen-rich blood which is then pumped around the body to supply your muscles with the oxygen in order to do aerobic respiration. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. When plaque builds up in the arteries, the condition is called atherosclerosis and it can be fatal. Coronary Artery Disease is also the most well known form of the disease. As you can see above the artery labeled "B" has endured a build up of plaque, which can then lead to blood clots and this is known as atherosclerosis which causes this person to have a lack of oxygenated blood being allowed to reach their heart. ...read more.


They both obviously believe that smoking is a major cause of heart disease which I'm sure many other charities and businesses believe the same thing but one thing both and many other websites I have looked at on the internet believe Second Hand Smoke or Passive Smoking is a major cause of deaths throughout the UK as it says in the first source from HeartPro.Co.Uk "35,000 people die from Passive Smoking each year" which is a massive amount. It also says "When you smoke, the people around you are also at risk for developing health problems, especially children" This is a key point "Especially children" it is a known fact the children are very prone to developing certain problems such as asthma and wheezing. The BBC Website reads "Their lungs are still developing, and at that stage they are much more susceptible to infection" Which is a serious concern for parents who do smoke or should be anyway... Copied And Edited By Myself http://news.bbc.co.uk/2/hi/health/1114132.stm The build up of plaque in this artery from smoking and maybe a bad diet can mean less blood to the muscles and if there is a major build up of plaque that could mean no oxygen and blood supply to the muscles or heart which then means...A heart attack... As you can see in this diagram there is a blockage in the artery due to a blood clot and plaque. We then have below that dying muscle; this muscle is dying because no oxygen is able to get to that part of the heart. This will lead to a heart attack... http://pbm.tnw.utwente.nl/master/master/Bat.doc/Bat-1.jpg Is passive smoking another major cause of heart disease? Passive smoking is the involuntary inhalation of smoke from tobacco products. It occurs when tobacco smoke permeates any environment, causing inhalation by all people within that environment. Such smoke is called secondhand smoke or environmental tobacco smoke (ETS). ...read more.


and sitting in with a McDonalds, a cigarette in one hand and a Pepsi Max in the other is a serious problem. The government, in my opinion, need to do more to get not only young but the older section of the nation as well involved in exercise on a regular basis. Let me ask you, if you go out and walk through your nearest town or city near you and you take a look around and see how many people are sat in the Pub or McDonald's and then have a look and see how many people are in the Gym or out on a run, I think you will realise what I am trying to get through to you...? The government just simply has to pump more money into the problem and into sports camps and sites but at the moment if we keep going at the rate we are going at by 2020 Heart Disease will be almost an un-talked about issue. Which is what we as a nation must strive for. But for weather smoking is the main cause of heart disease, I believe it is not the main cause of heart disease. I personally believe that diet and fat intakes and little exercise is the main cause of heart disease for the simple reason... More people die from obesity linked diseases (Heart Disease) each year, than smoking diseases... http://regional-institute.buffalo.edu/includes/TempFiles/Chart1467.gif This pie chart here quite clearly explains my point, this pie chart is showing us that more people die from heart disease whilst being obese than those who are not obese... Therefore I now believe that the government must concentrate on obesity and CAD as it is taking more lives each year than smoking is doing but again we cannot let it slip our minds, smoking is still a major cause of heart disease and measures must still be taken to try cut the number of deaths through smoking whilst taking measures to cut the number of deaths through obesity... ...read more.
