The JNC8 committee independently published an evidence-based guideline in JAMA that raised the blood pressure treatment threshold in most older adults from 140/90 to 150/90 mm Hg. In 2013, well into the development of JNC8, the NHLBI abruptly turned the process over to the American College of Cardiology/American Heart Association (ACC/AHA). From 1977 to 2003, seven Joint National Committees (JNC), sponsored by the National Heart, Lung, and Blood Institute (NHLBI), produced consensus multispecialty guidelines on the diagnosis and management of hypertension.
