Abstract

Of 1,177,896 patients with type 2 diabetes, 772,336 (66%) were free from cardiovascular or renal disease (CVRD) at the start of the study.

  • Over a mean follow-up of 4.5 years, 137,081 patients (18%) developed their first manifestation of CVRD.
  • The most common initial manifestations were chronic kidney disease (36%), heart failure (24%), stroke (16%), myocardial infarction (14%), and peripheral artery disease (10%).
  • Heart failure and chronic kidney disease were linked to significantly higher risks of cardiovascular and all-cause mortality.
  • The hazard ratios for heart failure and chronic kidney disease were 2.02 and 2.05, respectively, indicating more than double the risk compared to those free of CVRD.
  • The combination of heart failure and chronic kidney disease presented the highest mortality risks, with hazard ratios of 3.91 and 3.14 for cardiovascular and all-cause mortality, respectively.
