Heart disease in women started increasing as more women entered the workplace and acquired the same stress as men had always had.
I've heard other people say this, but I'm curious about whether there is any data to back it up. I have also heard for decades that doctors just didn't recognize the symptoms of heart disease in women, because they weren't looking for it. A man and a woman could go to the ER with the same symptoms; he'd be diagnosed with a mild heart attack and hospitalized, she'd be sent home with a diagnosis of indigestion and an antacid.
(Incidentally, my grandmother never worked outside the home a day in her life. She had a radical mastectomy at age 80, but died at age 95 when her heart finally gave out.)
