Under 40 With High Blood Pressure? Be Wary of Heart Risks - The New York Times

About half the group had normal blood pressure of 120/80 or lower. Compared with them, those with elevated pressure — 120-129/80 or higher — were 67 percent more likely to have had cardiovascular problems. People with readings of 130-139/80-89 had a 75 percent increased risk, and those with readings above 140/90 were three and a half times as likely to have some type of cardiovascular disease.
