Cases and comparators were followed with respect to the outcomes through linkage to the Swedish Inpatient Registry. Over a median follow‐up time of 5.7 years, there were 28 855 acute myocardial infarction and 33 060 heart failure cases among patients and comparators. Excess risk (above that of comparators in whom no data on hemoglobin A1c and <jats:styled-content style="fixed-case">BMI</jats:styled-content> was available), incidence rates and hazard ratios for heart failure were substantially higher among the obese patients compared with those with low <jats:styled-content style="fixed-case">BMI</jats:styled-content> , where very obese patients ( <jats:styled-content style="fixed-case">BMI</jats:styled-content> ≥40 kg/m <jats:sup>2</jats:sup> ) who also had poor glycemic control, suffered a 7‐fold risk of heart failure versus comparators (reference level). By contrast, for acute myocardial infarction, the highest absolute and relative risks were found among patients with poor glycemic control, with no additional risk conferred by increasing <jats:styled-content style="fixed-case">BMI</jats:styled-content> . </jats:p> </jats:sec> <jats:sec xml:lang="en"> <jats:title>Conclusions</jats:title> <jats:p xml:lang="en"> <jats:styled-content style="fixed-case">BMI</jats:styled-content> is a strong independent risk factor for heart failure but not for acute myocardial infarction among patients with type 2 diabetes mellitus. </jats:p> </jats:sec>
