I would imagine it's because Type 2 can often go undiagnosed for several years, normally affects older adults (but not always!), and there are often other risks present. Type 1 tends to be diagnosed more rapidly with fewer associated risks, and often in younger people.
Interesting when I was diagnosed and they told me I'd had a heart attack - they said I probably didn't feel it because diabetics lose nerve sensation, also that we were more susceptible to heart disease. They didn't take into account that I had, up until the previous week, been actively training for a marathon and had no associated risk factors at all, apart from being a smoker 13 years previously. Indeed, when they performed the angiogram, the surgeon said my arteries were 'pristine'! Clearly, they were applying a little layman's generalisations without looking at my own particular history (or, indeed, looking at me! 😱)
