DEAR DOCTORS: I'm a 38-year-old woman in good health. I kept getting a tight chest while running, so my doctor did some tests. He said my heart looked fine. But when I went for a second opinion, I was diagnosed with microvascular disease. I've never even heard of that before. What is it?
DEAR READER: You've introduced a topic of great importance to women of all ages: the fact that cardiovascular disease often takes a different form -- and comes with different symptoms -- in women than in men.
