Cardiovascular disease (CVD) is a major cause of mortality in people with Type 1 diabetes (T1D), especially in those with nephropathy (DN). However, in long-duration T1D, a substantial proportion of individuals without DN still exhibit excessive CVD risks. The Joslin 50-Year “Medalist” Study (n=1043), composed of people with T1D≥50 years, are ideal for studying CVD in a renoprotected T1D cohort, as only 13% have DN, and yet 40% have CVD, despite excellent control of lipids and blood pressure. Stratifying the Medalists by DN revealed that exercise was cardioprotective in the group with DN (OR 0.60, p=0.04); while age at T1D diagnosis (OR 1.03, p=0.01), HbA1c (OR 1.25, p=0.01), C-reactive protein (OR 1.14, p=0.01), and interleukin-6 (OR 1.13, p=0.01) all increased CVD risk in Medalists without DN. A subset of Medalists also underwent coronary artery calcification scans (CAC; n=153) and cardiac magnetic resonance imaging of left ventricular (LV) structure and function (CMR; n=111). The majority of these Medalists (97.8%) had detectable CAC>0; furthermore, the median CAC score of 1000 was higher at any cutoff compared to similar age-matched T1D and Type 2 diabetes (T2D) populations with higher DN prevalence. In contrast, mean CMR values in this Medalist subset were comparable to other cohorts. Continuous glucose…
How strong is the evidence?
Evidence Hub reads this as a cohort study, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 1,043 participants or records.
