Insights
Dysregulated sympathetic nervous system activity contributes to cardiovascular diseases. Sympathetic blockade offers therapeutic benefits for hypertension, atrial fibrillation, and heart failure, with ongoing advancements in monitoring sympathetic function.
Area of Science:
- Cardiology
- Neuroscience
- Pharmacology
Background:
- Sympathetic nervous system dysregulation is central to cardiovascular disease (CVD) development and progression.
- Understanding and modulating sympathetic activity are critical for managing various cardiovascular conditions.
- Chronic sympathetic activation involves multiple pathways implicated in CVD.
Purpose of the Study:
- To review existing literature on sympathetic blockade for managing hypertension, atrial fibrillation, coronary artery disease, heart failure, and perioperative care.
- To evaluate both pharmacological and non-pharmacological approaches to sympathetic modulation.
- To discuss advancements in measuring sympathetic nervous system activity.
Main Methods:
- Systematic review of studies on sympathetic blockade in cardiovascular disease management.
- Analysis of pharmacological interventions (e.g., beta-blockers).
- Inclusion of non-pharmacological management strategies and new monitoring techniques.
Main Results:
- Sympathetic blockade remains valuable for hypertension management and heart rate control in atrial fibrillation.
- Beta-adrenergic antagonists are important for symptom control and secondary prevention in ischemic heart disease, though revascularization impacts their role.
- Sympathetic blockade demonstrates efficacy in improving clinical outcomes for patients with heart failure.
Conclusions:
- Targeting the sympathetic nervous system is a key strategy in cardiovascular medicine.
- Advancements in sympathetic activity measurement enhance our understanding and potential interventions.
- Sympathetic blockade continues to be a relevant therapeutic approach across a spectrum of cardiovascular diseases.
Introduction:
A dysregulated sympathetic nervous system is a major factor in the development and progression of cardiovascular disease; thus, understanding the mechanism and function of the sympathetic nervous system and appropriately regulating sympathetic activity to treat various cardiovascular diseases are crucial. Areas covered: This review focused on previous studies in managing hypertension, atrial fibrillation, coronary artery disease, heart failure, and perioperative management with sympathetic blockade. We reviewed both pharmacological and non-pharmacological management. Expert commentary: Chronic sympathetic nervous system activation is related to several cardiovascular diseases mediated by various pathways. Advancement in measuring sympathetic activity makes visualizing noninvasively and evaluating the activation level even in single fibers possible. Evidence suggests that sympathetic blockade still has a role in managing hypertension and controlling the heart rate in atrial fibrillation. For ischemic heart disease, beta-adrenergic receptor antagonists have been considered a milestone drug to control symptoms and prevent long-term adverse effects, although its clinical implication has become less potent in the era of successful revascularization. Owing to pathologic involvement of sympathetic nervous system activation in heart failure progression, sympathetic blockade has proved its value in improving the clinical course of patients with heart failure.

Organic nitrates, such as nitroglycerin, play a pivotal role. Once metabolized, they liberate nitric oxide, a molecular marvel. Nitric oxide triggers guanylyl cyclase and augments cGMP production. This biochemical cascade orchestrates the relaxation of vascular smooth muscles, ushering in vasodilation and enhancing coronary blood flow....
