Physical Activity Helps Prevent Atherosclerosis
Jakarta, Kompas - Physical activity in the form of sports, daily activities and even dancing are done routinely useful to prevent atherosclerosis (fatty deposits on artery walls). This was proven by autopsy seven-time Boston marathon champion, Clarence DeMar, which indicates the size of coronary arteries from two to three times its normal size and did not reveal any stenosis (narrowing of blood vessels) are significant despite the age of 69 years died.
Relation of physical activity with coronary heart disease prevention due to atherosclerosis is discussed Dr. Dr. Dede Kusmana SpJP (K) (60), in a speech at the inaugural ceremony as Professor of Cardiology at Stay in the Science Faculty of Medicine, University of Indonesia, Wednesday (18/6).
According to Dede who is also Chairman of the Section of Cardiology Faculty of medicine, especially aerobic physical activity increases blood flow which is a wave that encourage increased production of nitric oxide (NO) and stimulate the formation and release of endothelial relaxing Derive factor (EDRF), which relax and dilate blood vessels.
Coronary blood flow during rest approximately 200 ml per minute (four per cent of the total cardiac output). Lab studies show, increase blood flow 4 ml per minute was able to produce NO to stimulate the improvement of endothelial function (lining) of blood vessels.
"Therefore, being in the form of physical activity or walking exercise that increases blood flow to 350 ml per minute (up by 150 ml per minute) was more than enough to avoid the vascular endothelium of the atherosclerotic process," says Dede.
However, the benefits can only be obtained if the increase in blood flow through regular physical activity takes place in a long time (20 minutes to an hour), and performed regularly for life.
Mechanism of atherosclerosis
Dede explains that atherosclerosis begins with buildup of cholesterol, especially LDL-cholesterol ester (low density lipoprotein) in the arterial wall. LDL normally get in and out of the artery through the endothelial wall. The entry of lipoproteins into the inner lining of the blood vessel wall increases with the high number of lipoproteins in plasma (hyperlipidemia), the size of the lipoprotein and blood pressure (hypertension). Increase in all it will increase the permeability of the blood vessel walls, thereby precipitated lipoproteins and cholesterol esters in the arterial wall.
Malfunctioning of the blood vessel lining became the beginning of the process of atherosclerosis and inflammatory mechanisms and encourage infection.
Inflammation or inflammation is the body's basic response to injury (injuries). Injuries are usually caused by infection, but can also be allergic or immunological reaction.
Clinical manifestations of the complex process of atherosclerosis is coronary heart disease, stroke and even death.
According to the Framingham study, as Dede, C-reactive protein (CRP) is a sign (marker) inflammation associated with cardiovascular events and stroke.
Efforts to suppress inflammatory factors may prevent the atherosclerotic process. Regular physical activity is proven to suppress CRP, mean also suppress inflammatory factors.
Therefore, moving or doing regular physical activity is an early concept of cardiovascular disease prevention and rational efforts for patients with cardiovascular disorders in cardiac rehabilitation.
Resistance training combined with weight training for four months been shown to decrease levels of TNF alpha (a type of inflammatory cytokines) were significantly reduced in patients with heart failure and coronary heart disease.
Type of activity
In healthy people, the prevalence of hypertension, hyperlipidemia, and ischemia (blood deficiency conditions in the network) is lower in people with more severe physical activity and regular than irregular or no exercise.
May be concluded, regular physical activity have the protection against cardiovascular mortality as well as other diseases due to lifestyle (non communicable disease).
No need to exercise a difficult and expensive. Walking six miles per hour, aerobics weight is, dancing is adequate to maintain cardiovascular health. Similarly, the equivalent of activities such as climbing stairs two levels, carrying 10 kilograms, hoe, or gardening.
"Activities of any origin can increase heart rate between 110-130 per minute, accompanied by sweating and increased respiratory rate but not until the panting is good enough to prevent heart disease and stroke," explained Dede. (ATK)

Maintain Lifestyle, Avoiding Atherosclerosis
Currently patients with heart disease or stroke is increasing in number. Not only that, patients are increasingly younger ages. This is because high levels of life stress and lifestyle is not maintained.
If the pattern or lifestyle is not maintained and even misguided, will eventually happen atherosclerosis in our bodies. "Atherosclerosis is a disorder of the heart arteries (coronary) is narrowing," says Prof. Dr. Slamet Suyono MD, Chairman of Diseases Society of Atherosclerosis and Vascular Diseases Indonesia, Saturday (26/8) in Jakarta.
Due to the narrowing of blood vessels, the heart does not get food. In fact, the heart beat continues every day and need the calories obtained from the blood flow to the heart, the result of constriction of blood vessels, the heart was not getting the food so that there was a heart attack.
Now there is a tendency of a heart attack is gradually increasing in number, both globally and in Indonesia. This is due to the wrong lifestyle. Now we tend to eat foods that contain lots of calories, such as rice, fat, sugar, and salt.
If we eat too much, it could lead to obesity. Increased cholesterol, diabetes will also appear. All these factors will lead to atherosclerosis.
In addition, our society is too busy at work from morning till night. For example, sitting at a computer all day so no chance to exercise or move the body. In fact, exercise is essential to accelerate the blood vessels.
The amount of work can also lead to high stress of having to chase the target. That all are factors that support the narrowing of blood vessels.
"Atherosclerosis is the upstream, downstream is a heart attack. Therefore we must do to prevent stroke or heart attack," said Slamet Suyono.
Change your lifestyle
To prevent atherosclerosis resulting in heart attack or stroke, we must change our lifestyle is wrong.
"Do not wait to change your lifestyle if you are aged 40 years and over, but since the children's lifestyle must be maintained. Children are now a lot of fat from eating fatty foods, junk food, and did not move much. Now just a lot of kids play the game in front of the television or computer, "said Slamet Suyono.
Foods that are not maintained will improve cholesterol levels, high blood sugar also increased, plus the air pollution so that more blood vessels to narrow. These factors should be prevented from the beginning.
Adolescents also had to be educated about health, especially the bad things what would happen if we do not keep eating. (LOK)
