Insights
Diabetic cardiomyopathy (DCM) involves altered heart metabolism and inflammation, leading to cardiac dysfunction. Early imaging identification of DCM can improve patient therapy and prognosis.
Area of Science:
- Cardiology
- Endocrinology
- Medical Imaging
Background:
- Diabetes mellitus (DM) is a major cardiovascular risk factor.
- Diabetic cardiomyopathy (DCM) is a serious complication of DM.
- Pathophysiology involves altered cardiac metabolism, hyperglycemia, advanced glycation end-products (AGEs), and inflammation.
Purpose of the Study:
- To describe the key imaging features of diabetic cardiomyopathy (DCM).
- To emphasize the role of early DCM detection in optimizing patient therapy and prognosis.
Main Methods:
- Review of current literature on diabetic cardiomyopathy.
- Focus on non-invasive imaging techniques such as echocardiography and cardiac magnetic resonance.
Main Results:
- DCM manifests as cardiomyocyte apoptosis, interstitial fibrosis, and mechanical dysfunction.
- Imaging can identify anatomical and functional cardiac remodeling in DCM patients.
Conclusions:
- Early identification of DCM through imaging is crucial.
- Optimizing therapy and improving prognosis are potential benefits of early DCM detection.
Abstract:
Diabetes mellitus (DM) is one of the most prevalent cardiovascular risk factors in the general population, being associated with high morbidity and socioeconomic burden. Diabetic cardiomyopathy (DCM) is a non-negligible complication of DM, whose pathophysiological fundaments are the altered cardiac metabolism, the hyperglycemia-triggered formation of advanced glycation end-products (AGEs) and the inflammatory milieu which are typical in diabetic patients. These metabolic abnormalities lead to cardiomyocytes apoptosis, interstitial fibrosis and mechanical cardiac dysfunction, which can be identified with non-invasive imaging techniques, like echocardiography and cardiac magnetic resonance. This review aims to: 1) describe the major imaging features of DCM; 2) highlight how early identification of DCM-related anatomical and functional remodeling might allow patients' therapy optimization and prognosis improvement.
