The country’s oldest heart disease study, run by Boston University and the National Heart, Lung, and Blood Institute (NHLBI), will research how aging affects the heart and other organs, from the brain to the liver.

The Framingham Heart Study (FHS), which has been running for more than 70 years, has received $38 million from the NHLBI to conduct the new six-year study, which will explore changes in blood pressure, arterial stiffness, blood platelets, and liver fat accumulation in the study’s older subjects. Many of those people are the children or grandchildren of the first participants in the FHS, which began when Harry Truman was president in 1948.

More info on the study, its history and its goals are available in this Boston University press release and several local news publications.
