What Is Coronary Heart Disease?
Coronary Heart Disease is our second "killer" in Hong Kong. On average, around five thousand people died of various heart diseases, of which nearly 50% to 60% died of myocardial infarction caused by coronary heart disease.
Coronary is surrounded by blood vessels to supply oxygen and nutrients to the heart muscle, in order to maintain the operation of the heart. If the coronary artery is narrowing or in a state of occlusion, blood supply to the heart would be reduced, resulting in hypoxic heart muscle and end up to be coronary heart disease. When the situation of coronary occlusion is worsening, it t will also lead to angina or fatal myocardial infarction (commonly known as a heart attack). People getting older will also have higher the chance of getting the disease. And patients with high blood pressure, diabetes and high blood fat are more likely to have coronary heart disease. If one’s family has a close family member suffering from heart disease, chance of getting coronary heart disease also increases.
Choesterol increase the risk of disease:
Urban people have a busy lifestyle, an unbalanced diet and lack of exercise. Many of them often consume too much fat. Cholesterol is an important fat in blood, having a great relationship with coronary heart disease. If cholesterol in the blood is too high, it will accumulate in the blood vessel wall easily. With the passage of time, it can cause vascular stenosis or occlusion of blood vessels, leading to heart disease.
