Insights

Heart failure is a neuroendocrine syndrome, not just pump dysfunction. Beta-blockers (BAAs) are standard for systolic dysfunction heart failure and may benefit dogs.

Area of Science:

  • Cardiology
  • Neuroendocrinology

Background:

  • Heart failure is increasingly recognized as a complex neuroendocrine syndrome.
  • Chronic adrenergic nervous system activation contributes to heart failure pathogenesis.
  • Detrimental effects of sustained adrenergic drive on myocardial function are evident.

Purpose of the Study:

  • To discuss the neuroendocrine basis of heart failure.
  • To highlight the role of beta-blocker agents (BAAs) in managing heart failure.
  • To explore the potential application of beta-blockade in canine heart failure.

Main Methods:

  • Review of current scientific literature on heart failure.
  • Analysis of the role of neuroendocrine pathways in heart failure.
  • Evaluation of the efficacy of beta-blocker therapy.

Main Results:

  • The traditional view of heart failure as solely pump failure is outdated.
  • Neuroendocrine system activation is integral to heart failure development.
  • Beta-blocker agents are established therapy for human systolic heart failure.

Conclusions:

  • Heart failure management should consider its neuroendocrine components.
  • Beta-blocker agents offer therapeutic benefits for heart failure patients.
  • Beta-blockade shows promise for managing heart failure in dogs.

Adrenergic Antagonists: Pharmacological Actions of β-Receptor Blockers

β-receptor blockers significantly impact the cardiovascular system by counteracting catecholamine-induced sympathetic responses. These medications decrease heart rate, contractility, and cardiac output, potentially leading to cardiac depression, life-threatening bradycardia, and death. Therapeutically, β-blockers function as mild antihypertensives and are utilized in treating angina pectoris and cardiac arrhythmias. However, nonselective β-blockers inhibit β2-receptors in bronchial smooth...

Adrenergic Antagonists: ɑ and β-Receptor Blockers

Third-generation β-blockers, such as labetalol and carvedilol, represent a significant advancement in managing cardiovascular conditions. Unlike conventional β-blockers, which can induce peripheral vasoconstriction, third-generation drugs block α1 adrenoceptors. This promotes vasodilation through several mechanisms, such as increased nitric oxide production, inhibition of calcium ion entry, opening of potassium ion channels, and antioxidant action. Labetalol, for instance, is clinically...

Antihypertensive Drugs: Types of β-Blockers

β receptors are classified into three subclasses: β1, β2, and β3. β1 receptors are primarily located in the heart and kidneys. When they get activated, they increase heart rate, contractility, and renin release. This process enhances blood pressure and aids in stress management. In contrast, β2 receptors are situated mainly in the lungs, blood vessels, and skeletal muscles. Upon activation, they trigger smooth muscle relaxation, causing bronchodilation and vasodilation. This widens airways and...
Heart Failure Drugs: Inhibitors of Renin-Angiotensin System01:26

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

Heart Failure Drugs: β-Blockers

β-adrenergic antagonists, commonly known as β-blockers, block the effects of sympathetic neurotransmitters such as noradrenaline (NA) and adrenaline (ADR). They have several beneficial effects in heart failure treatment. They reduce heart rate, the force of contraction, and cardiac muscle relaxation. They also slow the atrial-ventricular conduction rate and raise the threshold for arrhythmias. The concentration of β-blockers determines their effects on bronchodilation, vasodilation, and...
