Health Information for the Public

Contact the NHLBI Health Information Center

The National Heart, Lung, and Blood Institute (NHLBI) Health Information Center is open Monday through Friday, 10 a.m. to 4 p.m. Eastern time (closed on Federal holidays, the day after Thanksgiving, and December 24). Health Information Specialists are available to assist you and provide information on diseases of the heart, lung, and blood, and sleep disorders and accept orders for publications. After hours, you may leave a voicemail message or send an e-mail, and your inquiry will be answered the next business day.

As a research institute, the NHLBI does not provide referrals to doctors or counsel people on specific medical problems. Advice on treatment or care of an individual patient should be obtained through consultation with a physician or other health professional who has examined the patient and is familiar with the patient's medical history.

You can contact the NHLBI Health Information Center as noted below. Please indicate that your request results from a visit to the NHLBI website.
