Cause of cardiovascular diseases-Overview

Introduction on cvd

According to the World Health Organization, cardiovascular diseases causes 12 million deaths in the world each year. Cardiovascular disease is responsible for half of all deaths in the United States and other developed countries, and it is a main cause of death in many developing countries as well. Overall, it is the leading cause of death in adults.

In the United States, more than 60 million Americans have some form of heart disease. About 2600 people die every day of cardiovascular disease. Cancer, the second largest killer, accounts for only half as many deaths.

Coronary artery disease, the most common form of cardiovascular disease, is the leading cause of death in America today. This number one killer strikes a new victim every 2 seconds!

 How do we explain or define the cause of cardiovascular disease?

The medical profession tries to explain the cause of heart disease in terms of risk factors and not the actual cause of heart or cardiovascular disease. Researchers carry out studies involving thousands of patients, and they try to find out certain factors that play an important role in a person’s chances of developing heart disease. These are called as risk factors.

WHO and the cause of cardiovascular diseases

The reasons cited by WHO for the cause of any chronic disease including cardiovascular disease, is somewhat closer to reality. According to WHO heart disease causes include;

  • Unhealthy diet,
  • Lack of exercise and
  • Smoking.

Ultimately it is related to the nutrients that our tissues need and oxygen.  With lack of exercise there is less supply of oxygen because the flow of blood is slow. Exercise increases blood circulation and enhance the process of blood purification or fast removal of carbon dioxide from the body.

Similarly habits like smoking pollute our body with toxic gases like carbon monoxide and tar which might deposit on the tiny aeriols and block the transfer of oxygen and carbon dioxide from the lungs. Besides smoking depletes the body of antioxidants like vitamin c. This increases the demand of antioxidants by the tissues.

Researchers also study cardiovascular diseases causes based on:

Age of the person;

sex of the person;

hyperlipidaemia;

Race of the person;

etc such as cause of heart disease in men, cause of heart disease in women, American and African women and so on.

Other factors studied included disease conditions like:

Hypertension,

Diabetes and

Family history.

Apart from family history, the disease conditions like hypertension and diabetes are diseases related to dietary factors themselves.

People, cholesterol and cardiovascular disease

People are highly conscious cholesterol as the cause of heart disease.

It is firmly embeded in their mind that cholesterol causes heart disease.

Almost 90% of the people spend time on fats and cholesterol.

They see labels for cholesterol content and fat content as if it is going to make them healthy.

Is cholesterol really the cause of cardiovascular disease?

It has been established that cholesterol is not the real cause of heart disease.

The low fat diet that they are trying to consume has not solved the problem of high cholesterol levels or diseases of the heart.

They do not focus on the true cause of the heart disease, which is very much related to diet that they consume daily.

Healthy heart

A healthy heart needs sufficient oxygen and all the nutrients that our cells require. all the nutrients should be available in adequate amounts. This way the arteries remain clean. If the arteries are clean the heart is able to pumps blood to each and every tissue in the body in sufficient quantity.
Any deficiency of the nutrients leads to obstruction of blood flow caused due to atherosclerosis.

The key to optimal health is providing all the nutrients to the body in adequate amount, exercise and eating an alkaline diet menu plan, which maintains the body pH slightly on the alkaline side.
