Abstract:
Cardiovascular complications are the main cause of mortality and morbidity in the diabetic patients, in whom changes in myocardial structure and function have been described. Numerous molecular mechanisms have been proposed that could contribute to the development of a cardiac damage. In this regard, angiotensin II (Ang II), a proinflammatory peptide that constitutes the main effector of the renin-angiotensin system (RAS) has taken a relevant role. The aim of this review was to analyze the role of Ang II in the different biochemical pathways that could be involved in the development of cardiovascular damage during diabetes. We performed an exhaustive review in the main databases, using the following terms: angiotensin II, cardiovascular damage, renin angiotensin system, inflammation, and diabetes mellitus. Classically, the RAS has been defined as a complex system of enzymes, receptors, and peptides that help control the blood pressure and the fluid homeostasis. However, in recent years, this concept has undergone substantial changes. Although this system has been known for decades, recent discoveries in cellular and molecular biology, as well as cardiovascular physiology, have introduced a better understanding of its function and relationship to the development of the diabetic cardiomyopathy.
Insights
Diabetic patients face high cardiovascular risks due to cardiac damage. This review explores how angiotensin II (Ang II), a key part of the renin-angiotensin system (RAS), contributes to this damage through inflammation.
Area of Science:
- Cardiovascular Physiology
- Molecular Biology
- Endocrinology
Background:
- Cardiovascular complications are a leading cause of death in diabetic patients.
- Diabetic patients exhibit significant changes in myocardial structure and function.
- Angiotensin II (Ang II), a product of the renin-angiotensin system (RAS), is implicated in cardiac damage.
Purpose of the Study:
- To review the role of Ang II in biochemical pathways contributing to cardiovascular damage in diabetes.
- To understand the relationship between the renin-angiotensin system and diabetic cardiomyopathy.
Main Methods:
- Exhaustive literature review of major databases.
- Keywords used: angiotensin II, cardiovascular damage, renin angiotensin system, inflammation, diabetes mellitus.
Main Results:
- The renin-angiotensin system (RAS) plays a critical role in cardiovascular regulation.
- Recent research highlights the function of RAS and its link to diabetic cardiomyopathy.
- Ang II acts as a proinflammatory peptide contributing to cardiac damage.
Conclusions:
- Angiotensin II is a key mediator in the development of cardiovascular damage in diabetes.
- Understanding the molecular mechanisms involving Ang II is crucial for managing diabetic cardiomyopathy.
- The renin-angiotensin system's role extends beyond blood pressure control to include inflammatory pathways in diabetic hearts.
