Karen Lombardi, a school instructional coach, had just taken an unruly child out of a classroom when she felt severe chest pains. She drove to Yale New Haven Hospital, sweating profusely and hyperventilating, and was diagnosed with a heart attack. Five weeks later, she was back in the hospital with more chest pains. It was another four months before Lombardi, 61, learned the cause of her pain, received effective treatment and returned to active exercise. She considers herself lucky because many women with heart disease never get an accurate diagnosis.
