A heart surgeon has highlighted that some of the earliest warning signs of a possible blocked heart artery are not detected by devices, but by noticing patterns in the body during everyday activity.
The key symptoms include chest tightness, chest pain, shortness of breath, or discomfort that spreads to the jaw or arm while doing physical effort such as walking, climbing stairs, or household tasks. These symptoms may resemble angina, a condition where the heart muscle doesn’t receive enough oxygen during exertion. Guidance from organizations like the National Health Service and the Mayo Clinic describes angina as discomfort triggered by activity and relieved by rest.
