The quality of health information in the Internet may be low. This is a concerning issue in cardiovascular diseases which warrant patient self-management. We aimed to assess the quality of Portuguese websites as a source of health information on acute myocardial infarction and stroke.
We used the search terms 'enfarte miocardio' and 'acidente vascular cerebral' (Portuguese terms for myocardial infarction and stroke) on Google(®), on April 5th and 7th 2011, respectively, using Internet Explorer(®). The first 200 URL retrieved in each search were independently visited and Portuguese websites in Portuguese language were selected. We analysed and classified 121 websites for structural characteristics, information coverage and accuracy of the web pages with items defined a priori, trustworthiness in general according to the Health on the Net Foundation and regarding treatments using the DISCERN instrument (48 websites).
Websites were most frequently commercial (49.5%), not exclusively dedicated to acute myocardial infarction/ stroke (94.2%), and with information on medical facts (59.5%), using images, video or animation (60.3%). Websites' trustworthiness was low. None of the websites displayed the Health on the Net Foundation seal. Acute myocardial infarction/ stroke websites differed in information coverage but the accuracy of the information was acceptable, although often incomplete.
The quality of information on acute myocardial infarction/ stroke in Portuguese websites was acceptable. Trustworthiness was low, impairing users' capability of identifying potentially more reliable content.
互联网上健康信息的质量可能较低。在需要患者自我管理的心血管疾病方面，这是一个令人担忧的问题。我们旨在评估葡萄牙语网站作为急性心肌梗死和中风健康信息来源的质量。
我们分别于2011年4月5日和7日，使用互联网探索者浏览器，在谷歌上搜索“enfarte miocardio”和“acidente vascular cerebral”（葡萄牙语中急性心肌梗死和中风的表述）。对每次搜索中检索到的前200个网址进行独立访问，并选取葡萄牙语的葡萄牙网站。我们根据预先定义的项目，对121个网站的结构特征、信息覆盖范围和网页准确性进行了分析和分类，依据网络健康基金会评估了总体可信度，并使用DISCERN工具（48个网站）评估了治疗方面的可信度。
网站大多为商业性质（49.5%），并非专门致力于急性心肌梗死/中风（94.2%），且包含医学事实信息（59.5%），使用了图像、视频或动画（60.3%）。网站的可信度较低。没有一个网站展示网络健康基金会的标识。急性心肌梗死/中风网站在信息覆盖范围上存在差异，但信息准确性尚可接受，尽管往往不完整。
葡萄牙语网站上关于急性心肌梗死/中风的信息质量尚可接受。可信度较低，影响了用户识别潜在更可靠内容的能力。
