Latest Blood Pressure Study
Franco studied data from more than 3,100 people who were 50 years old.
They were tracked for up to 46 years. They got medical checkups every other year as part of the large Framingham Heart Study.
Their other health records were also noted. So were hospitalizations and death certificates.
Cholesterol and physical activity levels weren't always known. Other risk factors were considered. Those included smoking status, age, sex, body mass index (BMI), and education.
Less Time With Heart Disease
People with normal blood pressure didn't just live longer. They also spent fewer years with poor heart health.
Men with normal blood pressure lived seven more years without heart disease than those with high blood pressure. They spent two fewer years of their life with heart disease.
Women had similar benefits, say the researchers.
As blood pressure levels rose above normal, so did the risk of heart disease, heart attack, and stroke, they write.
Then and Now
The data were gathered decades ago, in the 1950s and 1960s.
Back then, blood pressure control in the U.S. was "poor," say the researchers.
Times have changed. Still, the researchers say the study shows what can happen if high blood pressure doesn't get appropriate treatment.
More studies should be done of people who are treated, they say.
The findings are "solid evidence" about the life-lengthening, heart-protecting benefits of curbing high blood pressure. So says Athanase Benetos, MD, PhD, in a journal editorial.
Benetos is an internal medicine and geriatrics professor at France's Centre de Gériatrie CHU-Nancy and INSERM U684.
