BOYNTON BEACH, Fla. – In the last five years, Dennis Ennis has lost five of his 12 siblings to congestive heart failure, but he didn’t consider his own risk, even when he started having shortness of breath. A visit to a cardiologist revealed he had indeed developed congestive heart failure, just like his siblings.
