Study Finds Possible Explanation for Dangerous Heart Complications in Flu Patients (video) Ohio State University Share Print E-Mail Loading video... Caption People with severe flu sometimes develop life-threatening heart problems, even when their hearts have been previously healthy, but the reason for that has been poorly understood. For the first time, research in mice has shown a link between a genetic mutation, flu and heart irregularities that researchers say might one day improve the care of flu patients. The study, led by Jacob Yount at The Ohio State University, appears in the journal Proceedings of the National Academy of Sciences.
