ABSTRACT
AIMS: To examine whether a transparent, rule-based cardiorenal-metabolic classification distinguished mortality and cardiovascular outcome patterns among adults with type 2 diabetes (T2D).
METHODS: This retrospective cohort included 61,250 adults with T2D from Hong Kong DM2016. Three phenotypes were defined from baseline cardiorenal burden and hypertension: lower-risk metabolic, hypertensive metabolic, and cardiorenal disease. Outcomes were all-cause and cardiovascular mortality, myocardial infarction, stroke, heart failure, and atrial fibrillation. Because individual follow-up times were unavailable in the public dataset, cardiovascular event outcomes were evaluated in outcome-specific at-risk cohorts. Modified Poisson regression estimated risk ratios (RRs).
RESULTS: The phenotypes comprised 29.4%, 20.9%, and 49.8% of participants, respectively. Compared with the lower-risk metabolic phenotype, the cardiorenal disease phenotype was associated with higher risks of all six outcomes; adjusted RRs ranged from 2.59 (95% CI, 2.36-2.84) for all-cause mortality to 9.17 (95% CI, 6.50-12.94) for myocardial infarction. The hypertensive metabolic phenotype was associated with myocardial infarction (RR, 1.56; 95% CI, 1.02-2.39), stroke (RR, 7.63; 95% CI, 5.27-11.06), and atrial fibrillation (RR, 1.76; 95% CI, 1.30-2.38), but not heart failure.
CONCLUSIONS: This transparent, rule-based classification summarized differences in recorded mortality and cardiovascular outcomes in T2D but should be interpreted as a descriptive framework rather than a validated prediction tool.
