Each year, more and more Americans are diagnosed with some form of heart disease and a lot of these cases breathe their last breath without realizing it. Most patients with cardiovascular complications are found to have clogged or hardened blood vessels or what cardiologists refer to as atherosclerosis. Many people believe that extremely high levels of cholesterol are at the root of this dreadful disease and they attribute this to the excessive consumption of fatty foods. However, there is more truth to be discovered than to accept this popular belief. Knowing more about the real causes of heart diseases can help a lot in lowering your chances of falling prey to this medical condition.

For years, heart attacks have been associated with high levels of cholesterol in the body. However, it is not merely cholesterol that causes the problem. What really causes it is the oxidation of cholesterol that is brought about by the presence of free radicals. Free radicals are those highly reactive elements that can cause a lot of damage to the cells and tissues in your body. These free radicals can attack your blood vessels that can result to atherosclerosis, a well known precursor to heart ailments and cardiovascular problems.

When free radicals and oxidative stress damage the walls of your blood vessels and cholesterol in your blood, atherosclerosis begins. Damaged cholesterol molecules are more likely to stick to the walls of your blood vessels and to each other, and can eventually clog a blood vessel, resulting to a heart attack.

Another condition that precipitates heart diseases is the oxidation of cholesterol. When cholesterol is oxidized, your body will react by sending more and more cholesterol to the distressed area in an effort to repair the damage. However, this can encourage the formation of plaque deposits. As plaque deposits increase, the blood vessel is narrowed and becomes stiffer. This will most likely impede blood flow to and from the heart and this can trigger a heart attack. Drugs that claim to reduce cholesterol amounts in the body can indeed lower cholesterol present in your bloodstream but these cannot guarantee protection from oxidation.

Atherosclerosis and heart diseases have no preferences as to which age group to attack. It can happen to anyone and may start early in life. Knowing even just a couple of causes of heart disease is important so you can do steps to avoid them. Learn more about the causes of heart disease and join the fight in battling this medical malady.

Leading the list is congenital heart disease. This is one of the most common types of heart disease that is not caused by external factors. This is passed down your blood line, from one generation to another. If you have heard of family members suffering from heart diseases early in their lives, better take caution and have yourself checked as the chances of you having a heart attack can be inevitable and unpreventable.

Congestive heart failure is a type of heart disease caused by inadequate supply of blood in the organs of the body. This can also result from constricted blood vessels. When the blood is unable to pump sufficient supply of blood, swelling, edema, and shortness of breath can occur and these often lead to heart attacks.

Perhaps the most common type of heart disease is what physicians refer to as coronary heart disease. This describes a damaged heart caused by insufficient blood supply and fat build up. Angina is a common manifestation of coronary heart disease. This refers to the pain felt when there is decreased supply of blood to the heart muscles.

Pulmonary heart disease is another type of heart ailment that many people suffer from. This type of heart disease is triggered by complications in the lung or lungs. Increased pressure in the lungs is often caused by slowed or blocked blood flow and leads to syncope, shortness of breath, chest pain, and dyspnoea.

There is also rheumatic heart disease, another one of the common types of heart disease. This can be caused by infections due to strep throat, especially when a patient suffers from rheumatic fever due to chronic sore throat. Although rare, people who often suffer from strep throat should take medications like cortisteroids to prevent any potential heart problems.

All these are various forms of aerobic exercises that not only keep you fit, but also help you to have a healthy heart. Aerobic, literally means “in the presence of oxygen”. Aerobic exercises are set of activities that let you move large muscles in your arms, legs, and hips continuously. While exercising, you will take fast and deep breath, which increases oxygen level in blood. Your heart will beat faster, and increases blood flow to your lungs and muscles. Capillaries in your body will get widened to release more oxygen to body muscles, and also helps in the removal of carbon dioxide and other wastes. Regular aerobic exercises are very beneficial.
