Last updated: 20 June 2026. By using drmikemacdonald.com (“the site”) you agree to these terms. The site is the personal blog of Dr Mike MacDonald and publishes general educational content about preventive cardiology and longevity.
Educational information, not medical advice
Everything on this site — articles, tools, calculators, videos and emails — is for general information and education only. It is not medical advice, diagnosis or treatment, and it is not a substitute for the advice of your own doctor or a qualified health professional who knows your individual circumstances. Always seek the advice of your physician with any questions about a medical condition, and never disregard or delay seeking medical advice because of something you have read here. If you think you may have a medical emergency, contact your local emergency services immediately.
The tools and calculators
The calculators provide general estimates based on published research. They are not diagnostic tools, they cannot account for your full medical history, and their results should be discussed with your own doctor rather than acted on alone.
No doctor–patient relationship
Using this site, subscribing to the newsletter, or contacting me through it does not create a doctor–patient relationship. I cannot provide personal medical advice by email or through this site.
Intellectual property
The content on this site is owned by Dr Mike MacDonald unless stated otherwise. You are welcome to read and share links to it, but please do not republish or reproduce substantial parts without permission.
External links and the course
The site links to other websites for convenience; I am not responsible for their content or practices. The “Essential Heart Health Tests” course is hosted on a third-party platform (Thinkific) and is subject to that platform’s own terms.
No warranties and limitation of liability
The site is provided “as is”, without warranties of any kind. To the fullest extent permitted by law, I accept no liability for any loss or harm arising from your use of, or reliance on, the information or tools on this site.
Governing law
These terms are governed by the laws of Singapore.
Changes and contact
I may update these terms from time to time; the “last updated” date will change when I do. Questions? Please get in touch.
