Insights
Diabetic cardiomyopathy (DCM) involves molecular heart changes unique to diabetes, distinct from other cardiomyopathies. Clinicians must recognize DCM symptoms and manage contributing factors alongside glucose control for better patient outcomes.
Area of Science:
- Cardiology
- Endocrinology
- Molecular Biology
Background:
- Diabetes mellitus is linked to increased cardiovascular mortality, often attributed to comorbid conditions like dyslipidemia and hypertension.
- Emerging evidence indicates that diabetes itself induces significant molecular alterations within the heart, independent of other risk factors.
Purpose of the Study:
- To conduct a comprehensive review of the pathophysiological and molecular changes associated with diabetic cardiomyopathy (DCM).
- To critically evaluate existing literature supporting or refuting the clinical manifestation of DCM.
Main Methods:
- Systematic literature review and critical analysis of studies on diabetic cardiomyopathy.
- Discussion of research examining unique cardiac remodeling patterns in diabetic patients.
Main Results:
- Studies confirm DCM exhibits a distinct cardiac remodeling pattern compared to other cardiomyopathies.
- Contrasting evidence exists regarding the clinical recognition of cardiomyopathy solely caused by diabetes, with ongoing debate presented and discussed.
Conclusions:
- Awareness of DCM is crucial for clinicians managing diabetic patients to enable timely symptom recognition and aggressive treatment of compounding factors.
- Understanding DCM's pathophysiology may unveil novel therapeutic targets for managing heart disease in diabetic individuals.
Background:
Although the increasing rate of cardiovascular mortality in patients with diabetes is thought to be due to the coronary atherosclerosis caused mainly by compounding factors such as dyslipidaemia and hypertension, it is now well documented that diabetes alone can lead to a vast array of molecular changes in the heart.
Design:
The aim of this article was to comprehensively review the pathophysiological and molecular changes leading to diabetic cardiomyopathy (DCM), as well as to critically analyse the literature that offers evidence in favour and against the existence of the overt clinical expression of this entity.
Results:
We included in the discussion studies that have revealed the existence of diabetic cardiomyopathy with unique remodelling pattern when compared to other types of cardiomyopathies. On the other hand, several studies debate the existence of clinically discernible cardiomyopathy caused only by diabetes and were also presented and discussed in details.
Conclusion:
Clinicians should be aware of DCM when facing patients with diabetes in order both to recognize on time relevant symptoms and to intensively look for and treat other compounding factors, apart from optimal glucose control. Furthermore, the elucidation of the pathophysiological mechanisms leading to DCM could provide new therapeutic targets for heart disease, which will be wonderful for the good of our patients.
