Insights

Acute myocardial infarction (AMI) impacts survival despite treatments. Targeting the 5-HT system, involved in depression and AMI, offers new therapeutic strategies for improving patient outcomes.

Area of Science:

  • Cardiovascular Medicine
  • Neuroscience
  • Pharmacology

Background:

  • Acute myocardial infarction (AMI) is a leading cause of global mortality with high post-event mortality rates.
  • Current treatments for AMI have limitations, necessitating novel therapeutic targets for improved patient recovery.
  • The serotonergic system (5-HT system) is implicated due to its link with depression, a condition frequently co-occurring with AMI.

Purpose of the Study:

  • To review the significance of the 5-HT system in the context of AMI.
  • To elucidate the role of specific serotonin receptors (5-HTRs) in cardiovascular responses during AMI and subsequent remodeling.
  • To highlight 5-HTRs as potential therapeutic targets for managing AMI.

Main Methods:

  • Literature review focusing on the serotonergic system and its receptors in cardiovascular physiology and pathology.
  • Analysis of signaling pathways for serotonin receptors 1, 2, 4, and 7 in the cardiovascular system.
  • Examination of the 5-HT system's involvement in AMI etiology and post-infarction processes.

Main Results:

  • The 5-HT system plays a crucial role in both physiological and pathophysiological cardiovascular responses.
  • Specific 5-HTRs (5-HT1, 5-HT2, 5-HT4, 5-HT7) are expressed in the cardiovascular system and are involved in AMI onset and remodeling.
  • The interplay between AMI and depression suggests the 5-HT system is a key factor in disease progression.

Conclusions:

  • The serotonergic system is integral to the pathophysiology of AMI.
  • Targeting specific 5-HTRs presents a promising avenue for novel therapeutic interventions to improve AMI outcomes.
  • Further research into 5-HTR signaling pathways is warranted for developing effective AMI treatments.

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

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...

Antidepressant Drugs: MAOIs and Other Agents

Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

G-protein Coupled Receptors01:21

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Drugs Affecting Neurotransmitter Release or Uptake

Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

Antianginal Drugs: Calcium Channel Blockers and Ranolazine

Angina pectoris, a primary symptom of ischemic heart disease, requires careful pharmacological interventions. In this context, calcium channel blockers (CCBs) and ranolazine have emerged as crucial pharmacotherapeutic agents, providing deep insights into the complexities of angina management.
CCBs, a diverse class that includes dihydropyridines (nifedipine) and diphenylalkylamines (verapamil and diltiazem), exert their effect by blocking calcium channels in cardiac and smooth muscle cells. This...
