As a medical professional, I can confirm that angina symptoms can indeed fluctuate. Angina is a type of chest pain or discomfort that occurs when there is not enough blood flow to the heart muscle, typically due to the narrowing of the coronary arteries. The pain associated with angina can be triggered by physical exertion or emotional stress, and it can be relieved with rest or medication. When the demand for blood by the heart is reduced, such as during rest, the symptoms of angina can subside. However, if the arteries are partially blocked, the blood flow may not be sufficient to meet the heart's needs, leading to the characteristic chest pain or discomfort. It's important to note that while the pain of angina may come and go, it is a sign of heart disease and can be treated. Seeking medical attention is crucial for proper diagnosis and treatment. read more >>
