Melatonin, a pineal hormone, plays a crucial role in heart regulation and cardiovascular health. This review summarizes melatonin

Area of Science:

  • Cardiovascular Physiology
  • Endocrinology
  • Pharmacology

Context:

  • The heart and cardiovascular system possess functional melatoninergic receptors.
  • Melatonin's role in cardiovascular regulation is increasingly recognized.
  • Melatonin deficiency is linked to cardiovascular diseases like coronary heart disease.

Purpose:

  • To review the multifaceted effects of melatonin on cardiac function.
  • To explore the mechanisms underlying melatonin's cardioprotective actions.
  • To summarize evidence regarding melatonin's influence on blood pressure and intracellular calcium.

Summary:

  • Melatonin demonstrates cardioprotective effects against ischemia-reperfusion injury and cardiotoxicity.
  • Melatonin administration lowers blood pressure in both normotensive and hypertensive individuals.

  • Pinealectomy (removal of the pineal gland) leads to hypertension, suggesting melatonin's hypotensive role.

    • Impact:

    • Highlights melatonin as a potential therapeutic agent for cardiovascular conditions.
    • Suggests novel mechanisms for managing hypertension and heart disease.
    • Provides a comprehensive overview for researchers and clinicians in cardiovascular medicine.
