TED: Noel Bairey Merz: The single biggest health threat women face - C. Noel Bairey Merz (2011)

Summary: Surprising, but true: More women now die of heart disease than men, yet cardiovascular research has long focused on men. Pioneering doctor C. Noel Bairey Merz shares what we know and don't know about women's heart health -- including the remarkably different symptoms women present during a heart attack (and why they're often missed).
