Causes of Angina Pectoris
The heart is the main organ in the body, where the circulation of blood and oxygen must always be smooth for other organs to work properly. Blood flowed into the heart through two large blood vessels called coronary arteries. In a certain period of time, the arteries at risk of plaque-treated like fat, cholesterol, calcium and other substances that result in narrowed and blocked blood vessels (atherosclerosis). This condition causes the heart muscle to work more, especially during heavy activity, which in turn has the potential to cause symptoms of angina pectoris, or worse is coronary heart disease (CHD).
The risk of a person experiencing angina pectoris increases as you enter old age, having hereditary cardiac abnormalities or symptoms of angina, and other medical conditions such as hypertension, high cholesterol, and diabetes. In addition, lifestyle is also a factor that can increase the risk, such as smoking, excessive alcohol consumption, eating fatty foods, lack of exercise, obesity, and stress.
