Some Risk Factors of Heart Disease

Heart disease also called Cardiovascular disease was the number one killer in US. About 2600 people in US die every day of this disease. According to the World Health Organization, cardiovascular disease causes 12 million deaths in the world each year. It was a serious problem that we as a researcher have to solve together to reduce the death cases which cause of this disease.
After many studies involving thousands of patients, researchers have found certain factors that play an important role in a person's chances of developing heart disease, these are called risk factor. Risk factors are divided into two categories: major factor and contributing factor. Major risk factors are those that have been proven to increase your risk of heart disease. Contributing risk factors are those that doctors think can lead to an increased risk of heart disease, but their exact role has not been defined.
The Major risk factors are : High Blood Pressure (Hypertension), High blood Cholesterol, Diabetes, Obesity and Overweight, Smoking, Physical Inactivity, Gender, Heredity, and Age. High blood pressure can increase your risk of heart disease, heart attack, and stroke. It’s also make your emotional unstabil. Too many Cholesterol in your blood could make a plaque on artery walls. If it was built in the coronary arteries that supply blood to your heart, you are at greater risk of having heart disease. The American Heart Association estimates that 65% of patients with diabetes die of some form of cardiovascular disease. Extra weight is thought to lead to increased total cholesterol levels, high blood pressure, and an increased risk of coronary artery disease. Research has shown that smoking increases heart rate, tightens major arteries, and can create irregularities in the timing of heartbeats, all of which make your heart work harder. People who are not active have a greater risk of heart attack than do people who exercise regularly. Exercise burns calories, helps to control cholesterol levels and diabetes, and may lower blood pressure. According to some research, men have a higher risk of heart attack than women. Heart disease also tends to run in families, if your parents have a heart disease, you will probably have this disease too. Older age is a risk factor for heart disease. As we age, our hearts tend to not work as well.
The Contributing risk factors are : Stress and Alcohol. Researchers have identified several reasons why stress may affect the heart. Stressful situations raise your heart rate and blood pressure, increasing your heart's need for oxygen. Studies have shown that the risk of heart disease in people who drink moderate amounts of alcohol is lower than in nondrinkers.
