Kardiologi.se is a Swedish-language cardiology resource aimed at doctors and nurses. It offers practical guidelines, scoring tools, and links to original research. That kind of specialized content is hard to maintain without real expertise, and the site shows signs of effort: a seven-year domain history, an About page, and active social media presence.
Still, there are a few things to watch. The site has no privacy policy, which is unusual for a health-focused site that may collect visitor data — especially since it probably serves an EU audience. It also loads a high number of external scripts and hides many page elements, which could be from plugins but is worth noting for a site that wants to appear trustworthy.
If you're a medical professional using the site as a quick reference, the content appears legitimate and well-organized. Just don't assume it handles your privacy by default. Check that you're comfortable with how it may be tracking you, and remember that no online reference replaces up-to-date clinical judgment.
