Angina is a discomfort or pain in the chest caused by reduced blood flow to the heart muscle. Some risk factors for developing angina include high blood pressure, high cholesterol, smoking, obesity, and diabetes. To prevent angina, it's essential to maintain a healthy lifestyle, which includes regular exercise, a balanced diet, and avoiding smoking. Additionally, managing stress and getting regular check-ups to monitor blood pressure and cholesterol levels can help reduce the risk of angina. Remember, early detection and prevention are key to maintaining good heart health.
