Insights
Cardiometabolic disorders harm coronary microvascular function, impacting cardiac performance and survival. This review explores molecular mechanisms behind coronary vasomotor tone dysregulation in conditions like obesity and diabetes.
Area of Science:
- Cardiovascular Research
- Metabolic Disease Mechanisms
- Vascular Biology
Background:
- Cardiometabolic disorders, including obesity, diabetes mellitus, and hyperhomocysteinemia, are linked to impaired coronary microvascular function.
- This dysfunction contributes to reduced cardiac performance and increased patient mortality.
- Understanding the underlying molecular mechanisms is crucial for effective therapeutic strategies.
Purpose of the Study:
- To review the molecular pathomechanisms of impaired coronary vasomotor tone regulation in cardiometabolic disorders.
- To focus on both endothelium-dependent and flow-induced dysregulation.
- To identify potential new targets for cardiometabolic prevention and treatment.
Main Methods:
- Comprehensive review of existing animal experiments and human studies.
- Analysis of molecular signaling pathways involved in coronary dysfunction.
- Synthesis of current knowledge on the relationship between cardiometabolic disorders and coronary function.
Main Results:
- Cardiometabolic disorders disrupt normal coronary vasomotor tone regulation through various molecular pathways.
- Impaired endothelium-dependent and flow-induced responses are key features of this dysfunction.
- Specific signaling mechanisms contributing to coronary artery disease in these conditions have been identified.
Conclusions:
- Molecular pathomechanisms underlying coronary vasomotor tone dysregulation in cardiometabolic disorders are complex.
- Identifying these mechanisms offers opportunities for novel therapeutic interventions.
- Targeting these pathways may improve prevention and treatment of cardiometabolic diseases and their cardiac consequences.
Abstract:
Cardiometabolic disorders have been shown to impair coronary microvascular functions leading to diminished cardiac performance and increased mortality. In this review, we focus on the molecular pathomechanisms of impaired endothelium-dependent and flow-induced dysregulation of coronary vasomotor tone in cardiometabolic disorders such as obesity, diabetes mellitus or hyperhomocysteinemia based on animal experiments and human studies. We also briefly summarize the relationship among key signaling mechanisms that contribute to the development of coronary dysfunctions in these disorders, which may help develop new targets for efficient cardiometabolic prevention and treatments.

Regulation of Angiogenesis and Blood Supply
Regulation of the Cardiovascular System
The regulation of the cardiovascular system involves the autonomic nervous system (ANS), baroreceptors, and chemoreceptors, ensuring that heart rate and blood pressure are appropriately modulated in response to varying physiological demands.
The ANS comprises two main divisions: the sympathetic and parasympathetic nervous systems. The sympathetic nervous system enhances...
