What Causes Heart Disease

The major causes of heart disease include hypertension (high blood pressure), high cholesterol levels (Low density Lipoprotein), diabetes, smoking, obesity, lack of exercise, and hereditary reasons as well. There are other reasons that increase the likelihood of developing a heart disease and will be discussed later in the article.

Heart disease is one of leading causes of death in men and women in the United States and in developing countries as well. Heart disease is a set of diseases associated with the heart with different intensity and etiology. Some of the common types include cardiomyopathy (heart muscle disease), coronary heart disease, cardiovascular disease, inflammatory and valvular heart disease, to name a few.

High blood pressure along with high level of LDL is a main cause that causes heart disease. These conditions increase the chances of clogging of blood vessels and impair the blood flow. The heart has to work harder to pump the blood in to the body and causes damage to the heart muscles.

Smoking is another leading cause of heart disease. Though people associate smoking mainly with lung diseases, combined with high blood pressure and increased levels of cholesterol it is also known to increase the risk of heart disease.

People who have a history of heart disease in their family have an increased risk of heart disease. Conditions like diabetes, obesity, high blood pressure are known to run in families and are risk factors that are commonly associated with heart disease. Some heart diseases are congenital and thus unavoidable.

Obesity and lack of exercise is another major cause of coronary diseases. Physical inactivity along with unhealthy eating habits leads to the build up of fatty tissue and bad cholesterol (LDL) in the blood. Deposition of this material on the walls of the blood vessel hampers blood flow to the heart and causes damage to heart muscle.

A lot of combined factors contribute to heart disease. Stress, alcohol, hormone imbalance, if present with some of the conditions above can increase the likelihood of heart diseases.

It is difficult to predict the specific cause of a heart disease in a person. It could largely be genetic, or mainly influenced by the person’s lifestyle. Whatever the case maybe there are known contributing factors that increase the chances of it developing into a serious fatal condition. The important thing is to maintain a healthy lifestyle, with regular exercise and nutritious diet, and to get a annual medical exam to regularly keep checking for any abnormality.
