Insights

Subarachnoid hemorrhage (SAH) can cause cardiac injury, but this damage is often reversible. Prioritize treating the brain injury, as cardiac function may improve.

Area of Science:

  • Neurology
  • Cardiology
  • Neurocritical Care

Background:

  • Cardiac injury is a known complication of various brain injuries.
  • Subarachnoid hemorrhage (SAH) is a frequently studied cause of neurocardiogenic injury.
  • Left ventricular (LV) dysfunction and elevated troponin levels are common in SAH patients.

Purpose of the Study:

  • To investigate the role of cardiac evaluation in patients with SAH.
  • To determine the prognostic and therapeutic value of echocardiography in SAH.
  • To assess the necessity of cardiac catheterization in SAH patients with cardiac dysfunction.

Main Methods:

  • Echocardiography for prognostication and treatment guidance when LV dysfunction or elevated troponin is present.
  • Clinical assessment focusing on the primary neurological condition.
  • Cardiac evaluation in brain death cases to potentially expand the donor pool.

Main Results:

  • Echocardiography can aid in prognostication and treatment planning for SAH.
  • Cardiac catheterization is not routinely recommended for SAH patients with LV dysfunction and elevated troponin.
  • Cardiac injury following SAH is generally reversible.
  • Cardiac evaluation in brain death may increase organ donor availability.

Conclusions:

  • Treatment of the underlying neurological condition is paramount in SAH patients, even with coexisting LV dysfunction.
  • Cardiac dysfunction associated with SAH is typically reversible.
  • Cardiac assessment in brain death scenarios can benefit organ donation efforts.

Secondary Spinal Cord Injury llI: Pathophysiology

Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Neurogenesis and Regeneration of Nervous Tissue

In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Spinal Cord Injury ll: Pathophysiology

Spinal cord injury progresses through two interconnected phases: primary injury and secondary injury.Primary InjuryPrimary injury happens at the moment of trauma and involves immediate mechanical damage to the spinal cord.Compression happens when broken vertebrae, herniated discs, or accumulating blood (such as a hematoma) press directly against the spinal cord, distorting its normal shape and function. In cases of contusion, the cord is bruised by a blunt force (like penetrating injuries or...

Disorders of the Autonomic Nervous System

The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Ischemic Stroke ll: Pathophysiology01:15

Ischemic Stroke ll: Pathophysiology

An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
