About Dr Mike
Cardiology that looks forward, not just back
Most cardiology happens after something has gone wrong. The work I care about happens earlier — finding the risk before it becomes a diagnosis, and giving people the knowledge and tools to do something about it.
This site is where I write, teach and build tools for the much larger group of people who want to take their cardiovascular health seriously but don’t know where to start. The day job is consultant cardiology in Singapore — what you find here is the writing I’d want my own family to read.
