Angina is a symptom of an underlying heart condition, typically caused by the narrowing of the coronary arteries due to atherosclerosis, which reduces the supply of oxygen-rich blood to the heart muscle. While it is possible for the pain of angina to subside temporarily, it is important to understand that the underlying condition is still present and angina can return. The pain of angina will last more than a few minutes or will go away and come back, which is indicative of the varying demand for oxygen by the heart. However, if symptoms do not go away with rest or the use of nitroglycerin, it could be a sign of unstable angina, which is a more serious condition that can lead to a heart attack and can cause lasting damage to the heart muscle. It is crucial for individuals experiencing persistent or unstable angina to seek immediate medical attention, as it may be a precursor to a heart attack. Treatment for angina aims to improve blood flow in the coronary arteries, reduce the workload on the heart, and manage the symptoms. Lifestyle changes, medications, and in some cases, medical procedures or surgery may be necessary to manage the condition. read more >>
