What can cause angina?

Angina is primarily caused by obstructed arterial blood flow to the heart, which leads to a temporary reduction in oxygen supply to the heart muscle. When the heart muscle does not receive enough oxygen-rich blood, it can result in chest pain or discomfort known as angina. This obstruction often occurs due to atherosclerosis, where plaque builds up in the coronary arteries, narrowing them and making it harder for blood to flow.

Maintaining good cardiovascular health is essential, as conditions that lead to blocked arteries—such as high cholesterol, high blood pressure, and smoking—can increase the risk of angina. As a result, it's crucial for healthcare providers to recognize and address risk factors that could contribute to this condition.
