Cardiovascular disease is the UK's number one cause of death, responsible for more than 900,000 deaths every year. Doctors call it the silent killer because, for many patients, a lethal heart attack or stroke is the first symptom. CT heart scanning that measure calcium in the coronary arteries. It involves two heart scanning tests that, they said, allow doctors to actually see evidence of cardiovascular disease, rather than depending, as doctors do now, on risk factors -- such as age, smoking history, and cholesterol levels -- to suggest there might be problems.
