When we are recommended an operation or healthcare intervention, it’s likely we’re going to want some information about it. Not just who will do it, where and when, but also the chances of whether it could damage, maim or even kill. All procedures – even straightforward ones – entail the risk of complication, so it’s important to be informed.
One way of doing this is to use “calculators” to predict these health risks. Some of these are available online, often targeted at assessing cardiovascular risk. By entering your age, smoking history, blood pressure, family history and diabetic status, a calculation is made projecting risk for cardiovascular disease over the following years.
