Rise in blood pressure in middle age signals stroke and heart attack risks, according to new Northwestern Medicine research. The study offers a new understanding on the importance of maintaining low blood pressure early in middle age to prevent heart disease later in life. Men and women who developed high blood pressure in middle age or who started out with high blood pressure had an estimated 30 percent increased risk of having a heart attack or stroke compared to those who kept their blood pressure low.
Previous estimates of a personfs risk of cardiovascular disease were based on a single blood pressure measurement. The higher the blood pressure reading, the greater the risk. The new Northwestern Medicine study expands on that by showing a more accurate predictor is a change in blood pressure from age 41 to 55.
The study is published in Circulation: Journal of the American Heart Association.
gWe found the longer we can prevent hypertension or postpone it, the lower the risk for cardiovascular disease,h said lead author Norrina Allen, assistant professor of preventive medicine at Northwestern University Feinberg School of Medicine. gEven for people with normal blood pressure, we want to make sure they keep it at that level, and it doesnft start increasing over time.h
gThere hasnft been as much of a focus on keeping it low when people are in their 40Œs and 50Œs,h Allen added. gThatfs before a lot of people start focusing on cardiovascular disease risk factors. Wefve shown itfs vital to start early.h
People that maintain or reduce their blood pressure to normal levels by age 55 have the lowest lifetime risk for a heart attack or a stroke.

Men generally have a 55 percent risk of cardiovascular disease in their lifetimes; women have a 40 percent risk.
gOur research suggests people can take preventive steps to keep their blood pressure low early on to reduce their chances of a heart attack or stroke,h said Donald M. Lloyd-Jones, MD, study co-author, chair of preventive medicine at Northwesternfs Feinberg School and a cardiologist at Northwestern Memorial Hospital. gMaintaining a healthy diet, combined with exercise and weight control, can help reduce blood pressure levels and, consequently, your risk for cardiovascular disease later in life.h
