National Heart, Lung, and Blood Institute

The National Heart, Lung, and Blood Institute (NHLBI) is worth visiting for its collection of heart, lung, and blood conditions. The site provides detailed information about all aspects of these conditions, including causes & risk factors, presentation, diagnosis, treatment, prevention, and living with the disease. Users can also access many relevant, credible resources and additional information.

Ease of Use

The site's major categories are distinct and clear, with most of the content organized by disease/condition. Uncluttered web pages and generous use of collapsible menus make it so that pages are informative and easy to browse. The Bing-powered search bar doesn't allow for filtering, but it is comprehensive and gives users the choice of which part of the website to search from.

Visual Design

The NHBLI website is professionally designed, presenting visitors with a homepage filled with relevant and meaningful images. Informational content pages are drab in comparison, but overall this is one of the better designed health websites supported by the U.S. government.


A comprehensive and detailed collection of information about a variety of heart, lung, and blood conditions. The information provided is not referenced, but is reported as being compliant with the U.S. Health and Human Services guidelines for ensuring the quality, objectivity, utility, and integrity of information disseminated to the public. Each page gives basic information followed by further reading, related health topics, and more.


No authors or editors are credited for individual articles, and there is no indication of those responsible for the content. However, the U.S. government's sponsorship provides a great deal of credibility. There use of posting and/or review dates is used inconsistently, too. But news coverage and research information is very up-to-date so that users can verify the site's currency.


  1. Provides readers with a complete picture of multiple heart, lung, and blood conditions
  2. Among the most authoritative health resources available to the public
  3. Writing is clear and can be understood by non-medical audiences
  4. Excellent collection of relevant resources for each condition


  1. Information sources are rarely identified
  2. Most general information is not dated
  3. Combining cardiovascular diseases with blood disorders is confusing, since they have little in common
