Short of doing an internet search for LADA I don't know where you can glean specific information.
Personally I view it as me, a 59-yr old man, getting T1 (misdiagnosed as T2), going through a honeymoon period and eventually needing to become insulin-dependent. Henceforth I expect to live as a T1 does.
In the UK I wouldn't expect a diabetic to be seeing a cardiologist, unless heart problems were presenting. Some will be under their GP alone, some with access to diabetic specialist nurses, some under an endocrinologist.
The GP/nurses would be watching for heart risk factors. This is all paid for by public taxation so unnecessary referrals to specialists are simply a drain on taxes.
Private consultations can always be paid for, and some people's private medical cover may help.
Never forget the term 'diabetic' is doing a lot of heavy lifting when used in a risk analysis. The well-controlled are lumped in with those who don't know or don't care how to manage their condition and see losing 'another' toe as a natural inevitability.
I can only surmise that I enjoyed a 4 1/2 years honeymoon because I went low-carb (the full LCHF) and put less strain on my pancreas :
** Think Like A Pancreas is recommended **

LCHF is growing in popularity.
https://www.dietdoctor.com is a great site to visit.
Good luck with your diabetic journey ! And keep asking questions !!
