Texas Health Dallas researchers publish major study examining connection between nausea and heart attacks

Researchers at Texas Health Presbyterian Hospital Dallas are investigating what symptoms could help doctors better spot heart attacks and if certain symptoms might indicate different types of heart attacks. Their most recent work, "Relation of Nausea and Vomiting in Acute Myocardial Infarction to Location of the Infarct," appears in the December edition of the American Journal of Cardiology. According to the findings, almost two-thirds of heart attack patients suffer nausea when arriving in the ER - but whether they have an upset stomach does not indicate where cardiac blood flow is blocked, said senior author Dr. Mark Feldman, chair of internal medicine at Texas Health Dallas and director of the hospital's internal medicine residency program - Texas Health Resources
