Heart attacks have been a mystery since ancient times, with early scholars breaking taboos to study them. By the 18th century, connections between chest pains and blood vessel issues were noted. Technological advances like the ECG and X-rays improved diagnosis. Blood clots were identified as a cause in the 1980s.
