After a heart attack, as much as half of the heart is so damaged it stops working. And the rest of the heart has to work harder. It’s like having two people on a bicycle built for two with only one of them pedaling, says Dr. Marco Costa, an interventional cardiologist with University Hospitals Harrington Heart & Vascular Institute. The person left pedaling has to pull more weight and becomes weaker and weaker over time.
