SIR,HOW DID HEART DIEASES OCCURES?
Cardiovascular disease can take many forms: high blood pressure, coronary artery disease, valvular heart disease, stroke, or rheumatic fever/rheumatic heart disease. High blood pressure increases your risk of heart disease, heart attack, and stroke.If you are obese, you smoke, or you have high blood cholesterol levels along with high blood pressure, your risk of heart disease or stroke greatly increases.

Blood pressure can vary with activity and with age, but a healthy adult who is resting generally has a systolic pressure reading between 120 and 130 and a diastolic pressure reading between 80 and 90 (or below). One of the major risk factors for heart disease is high blood cholesterol. Cholesterol, a fat-like substance carried in your blood, is found in all of your body's cells. Your liver produces all of the cholesterol your body needs to form cell membranes and to make certain hormones. Extra cholesterol enters your body when you eat foods that come from animals (meats, eggs, and dairy products).
 Heart problems are the leading cause of death among people with diabetes, especially in the case of adult-onset or Type II diabetes (also known as non-insulin-dependent diabetes). Obesity and Overweight. Extra weight is thought to lead to increased total cholesterol levels, high blood pressure, and an increased risk of coronary artery disease. Obesity increases your chances of developing other risk factors for heart disease, especially high blood pressure, high blood cholesterol, and diabetes. 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. Smoking also raises blood pressure, which increases the risk of stroke in people who already have high blood pressure.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. Heart disease tends to run in families. For example, if your parents or siblings had a heart or circulatory problem before age 55, then you are at greater risk for heart disease than someone who does not have that family history. Risk factors (including high blood pressure, diabetes, and obesity) may also be passed from one generation to another. Other contributory factors are stress, age, alcohol, birth control pill etc.
