For diabetes patients, heart disease can be a serious concern. Even diabetes patients with mild heart disease may benefit from proper treatment.

Some medications help patients in several ways — such as how an aspirin for a fever may also lower heart attack risk — but that isn't always the case. A medication for cholesterol once thought to improve bone health probably doesn't do so, a new study found.
