Eric, a security guard at Hennepin Healthcare, had been dealing with chest pains for about a week, but only when he bent over to do something like tie his shoes. “Heart attack symptoms were different than that,” he thought, “like major chest pains all the time or a shooting pain down your arm.” As an overall healthy man, he passed it off as something else. But one Sunday in January, 2019, he decided to stop ignoring it and went to the emergency department. Blood tests and an EKG were normal, but there was more to come.
