Longer diabetes duration significantly increases the risk of subclinical myocardial injury, indicated by elevated high-sensitivity cardiac troponin levels. Early diabetes prevention may mitigate this cardiac damage.
Area of Science:
- Cardiology
- Endocrinology
- Public Health
Background:
- Diabetes mellitus is a known risk factor for cardiovascular complications, including heart failure.
- The relationship between the duration of diabetes and subclinical myocardial injury requires further investigation.
Purpose of the Study:
- To examine the association between diabetes duration and subclinical myocardial injury.
- To assess subclinical myocardial injury using high-sensitivity cardiac troponin T (hs-cTnT) levels.
Main Methods:
- Analysis of 9052 participants from The Atherosclerosis Risk in Communities Study (ARIC).
- Diabetes duration was determined by diagnosis age or status across study visits.
- Multinomial logistic regression was used to associate diabetes duration with hs-cTnT levels, adjusting for covariates.
Main Results:
- Prevalence of elevated hs-cTnT increased with longer diabetes duration (0-4.9 years: 12%; ≥15 years: 31%).
- New-onset diabetes at Visit 4 showed a 1.92x higher risk of elevated hs-cTnT.
- Diabetes duration of ≥15 years was associated with a 9.29x higher risk of elevated hs-cTnT compared to no diabetes.
Conclusions:
- Prolonged diabetes duration is a significant predictor of subclinical myocardial injury.
- Interventions aimed at preventing or delaying diabetes onset may reduce early cardiac damage.
