When there is insufficient blood supply to the heart due to the accumulation of plaque in the blood vessels, it leads to a condition called angina. The heart responds by beating faster and harder to restore blood supply, and symptoms can vary from person to person. However, some common signs include discomfort, tightness, or heaviness in the chest, as well as pain in other parts of the body such as the back, shoulders, neck, or jaw. Other symptoms include shortness of breath, sweating, dizziness, and nausea. It is crucial for those experiencing these symptoms to seek medical assistance by visiting a cardiology hospital to avoid further complications. It is important to note that the severity of angina can vary among individuals, so seeking diagnosis is the best course of action to identify the underlying issue.
