It may not come as a surprise, but a new study suggests that people who reach middle age in good heart health can look forward to a longer, healthier life. The findings, published in the May 2 issue of the journal Circulation, were culled from an analysis that followed nearly 26,000 U.S. adults for 40 years.
The investigators found that people in optimal heart health in middle age lived an average of four years longer than their peers who had at least two risk factors for heart disease. In addition, the people with optimal heart health lived almost five years longer free of chronic disease — which is critical, the researchers said.
“It’s not just about quantity, but also quality of life,” said study leader Dr. Norrina Allen, an assistant professor of preventive medicine at Northwestern University, in Chicago.
While the findings might not startle anyone, they do give a clearer picture of how much middle-aged people stand to gain from heart-healthy habits, said Dr. Harlan Krumholz, a professor of medicine at Yale School of Medicine.
“Your future self will be grateful if you pay attention to these things in middle age,” said Dr. Krumholz, who co-authored an editorial published with the study.
The results are based on over 25,800 Chicago adults whose health had been tracked since the late 1960s and early 1970s. All were at least 65 years old by 2010.
At the study’s outset, only about 6 percent were in optimal cardiovascular health: That meant they had healthy blood pressure and cholesterol levels, and were normal-weight, nonsmokers and free of diabetes. In contrast, over three-quarters of the study group had at least one major risk factor for cardiovascular trouble — including high blood pressure, high cholesterol, diabetes, obesity or smoking.
Overall, the small group of people who were in optimal health aged more successfully, the researchers found, though the study couldn’t prove a cause-and-effect relationship. When the healthier people did suffer heart disease or a stroke, it was seven years later, on average, compared with people who’d had two or more risk factors back in middle-age, according to the report.
The people with optimal heart health also spent a greater part of their golden years free of major diseases — including cancer, kidney disease, chronic lung disease and dementia. That, in turn, translated into lower Medicare costs: almost $18,000 less, on average, the study authors said.
