Cardiovascular diseases

Updated on October 15, 2012

Introduction

Cardiovascular diseases are diseases that are very dangerous. They don’t infect only middle aged people and elderly but also small children. Somewhere in Britain, scientists have discovered that even children at the age of 7 aren’t safe from these diseases. Moreover, they discovered that several children at the age mentioned earlier, have certain cardiovascular diseases. It is taught that the fatty food and lack of movement of children are the causes of these diseases, but later on more about that.

Cardiovascular diseases are diseases of the heart, veins and arteries. Cardiovascular diseases include: Aneurysm, Angina, Atherosclerosis, Cerebrovascular Accident (Stroke), Cerebrovascular disease, Congestive Heart Failure, Coronary Artery Disease and Myocardial infarction (Heart Attack). All of these diseases are very dangerous and in some cases, life threatening.

Causes of Cardiovascular heart disease (Bad life habits)

The biggest cause of coronary heart disease is unhealthy food. Nowadays, people have modern ways of transportation and most of the time they just sit. This lack of movement combined with bad and unhealthy nutrition that people have today is causing the coronary heart disease. However, it wasn’t like this all of the time. Earlier people didn’t have these “modern” means of transportation (busses, trains, cars, etc) and that is why they had to walk more and move. Because of this and because those days there wasn’t any fast food, a lot less people had these coronary heart diseases. Nowadays the situation is very different. Many more people are infected but, a lot less people actually die from these diseases. The fact is that in the period from 1995 to 2005 the number of people that died from coronary heart diseases has fallen for 34.3 %. This is because scientists have discovered many cures and most importantly they have discovered some drugs that can save your life after you have a heart attack. Nevertheless, these aren’t the only causes of coronary heart diseases. There are many more like: as older you get the higher the chance of CHD, Males are more likely to be infected, people who have a family history of diseases should be more careful, high blood pressure, high blood cholesterol levels, high emotional stress, people who have obesity, people who smoke cigarettes and finally people who drink a lot of alcohol. You should really avoid these things mentioned if you don’t want to get a coronary heart disease. Having these bad life habits or at least some of them will surely cause CHD.

Coronary heart disease

Coronary heart disease is when your heart’s blood supplies are blocked due to build-ups of some fatty substances in your coronary arteries. As we get older, our arteries, especially the coronary arteries, get filled with fatty deposits. These fatty deposits stick to the arteries walls and create high blood pressure. This process of building up of fatty substances on the walls of the arteries is called atherosclerosis, and the fatty substances are called atheroma. Your coronary arteries can become so plugged up by these fatty substances that barely enough blood is coming to your hearth. This can cause angina (chest pains). Furthermore, the worst case scenario is that the arteries become fully blocked and then you will suffer a heart attack. This atheoma or plaque builds up in our arteries due to our unhealthy nutrition. People eat far too much fast food and that’s because they don’t have time to prepare and cook meals. They need to go to work and are busy all day. Fatty substances from this fast food get deposited on the walls in our arteries and eventually the arteries get narrowed and blocked up. Therefore, we can conclude that plaque growth and stability depends on the amount of unhealthy food (which contains atheoma) that is taken in by a certain person. The more food (mentioned earlier) we take in the more plaque gets stuck to our arteries. Women are lucky because they have some sex hormones that reduce the chance of the chance to get CHD. Oestrogens reduce the number of low-density lipoproteins in the blood which carry large amounts of cholesterol. Therefore, lot less fatty deposits sticks to the walls of female arteries.

How to reduce risk of coronary heart disease?


There are simple rules that people need to follow in order to reduce the chance to get coronary heart disease. Here they are:

  1. Eat less cholesterol, Trans and saturated fats. Also eat food that has very little or no sodium (salt) in it. Cook without salt and when eating try to eat without salt. These things clog your arteries and because of them people have high pressure. Moreover, blood pressure should be measured from time to time to check if it’s high.
  2. Try to exercise every day. This is important because it keeps your arteries working, burns up fat, keeps your immunity up and keeps your blood pressure down.
  3. Try to lose weight if necessary because if you’re overweight you have a high cholesterol level and high blood pressure.
  4. Avoid being stressed. When you are stressed your blood pressure is high so it would be better if you would look at the bright side of everything.
  5. Don’t smoke. Nicotine increases heart rate and blood pressure and constricts arteries and veins. In addition, when you are smoking the fatty deposits tend to stick more easily to the artery walls.
  6. Don’t drink a lot of alcohol. It raises your blood pressure. However, if you drink alcohol in moderate proportions it is very likely that it will reduce the risk of CHD.


One world

Here are some facts for the year 2006:

  • High blood pressure — 73,600,000
  • Coronary heart disease — 16,800,000
  • Myocardial infarction (acute heart attack) — 7,900,000
  • Angina pectoris (chest pain) — 9,800,000
  • Stroke — 6,500,000
  • Heart Failure — 5,700,000

It is really devastating to hear these things. It shows you how horrible this disease is. Scientists have so far discovered many things to prevent and to cure from CHD. Nowadays, over 80% of people who have a heart attack receive potentially life-saving drugs within 30 minutes of arrival at hospital. This really saves a lot of lives. Nevertheless, our technology in medicine is not developed enough to save all people. That is why there are still a lot of lives taken by this disease. Taking in consideration that this disease has taken so many lives it has affected the social lives of many other people like the relatives of the ones who suffer from these diseases. Also, the people who are infected may lose jobs because of their disability. Heart attach take a lot of lives in sudden occasions and some firms may lose certain important workers like directors and managers which is bad for the economy.

Conclusion

Having in mind all the things that I have learned about this disease I can say that scientists should try harder to find some medication to fight against these diseases. But not only are the scientists expected to do something. Moreover, ordinary people, the ones who suffer from these illnesses and the ones who don’t, have to make efforts to prevent and cure these diseases. We have to take out the harmful food that we are eating and to do more exercises. That is the first step to solving this “crisis”. In addition people should reduce smoking and alcohol. But let’s be real, how likely is this to happen? Very unlikely! Some people just don’t figure how big the consequences of eating fast food, drinking alcohol and smoking are until they get a disease like Coronary heart disease.
