Transient Middle Cerebral Artery Occlusion Model of Neonatal Stroke in P10 Rats
Published on: April 21, 2017
Summary
Patients with intracranial lesions show significantly higher rates of myocardial damage. This cardiac injury, linked to increased intracranial pressure, may stem from elevated plasma catecholamines.
Area of Science:
- Neuropathology
- Cardiovascular Pathology
- Histochemistry
Background:
- Intracranial lesions can affect systemic physiology.
- Myocardial damage is a potential complication.
- Histochemical methods can detect cellular changes.
Purpose of the Study:
- To compare myocardial damage in patients with intracranial lesions versus controls.
- To investigate the timing and characteristics of focal myocardial damage.
- To explore the relationship between intracranial pressure and cardiac pathology.
Main Methods:
- Autopsy examination of 58 patients with intracranial lesions and 50 controls.
- Histochemical staining for succinic dehydrogenase to assess myocardial damage.
- Correlation of cardiac findings with lesion type, intracranial pressure, and time of death.
Main Results:
- Significantly higher incidence of myocardial damage (62%) in patients with intracranial lesions compared to controls (26%).
- Focal myocardial damage developed after six hours, was not seen after two weeks, and was associated with rapid increases in intracranial pressure.
- Similar myocardial changes observed in control patients with shock or circulatory failure.
Conclusions:
- Rapidly increasing intracranial pressure, potentially via elevated plasma catecholamines, is implicated in focal myocardial damage.
- The observed cardiac lesions are distinct from those in sudden violent deaths.
- Cerebral pathology type influences the development of associated myocardial damage.

Myocarditis I: Introduction
Myocarditis is inflammation of the myocardium, which is the muscular layer of the heart.EtiologyMyocarditis has a diverse etiology, including a wide range of infectious and non-infectious causes:Infectious CausesViral: Common viruses include Coxsackie A and B, adenovirus, parvovirus B19, enteroviruses, and influenza A.Bacterial: Examples include infections caused by Streptococcus, Staphylococcus, and Mycoplasma species.Rickettsial: Infections like Rocky Mountain spotted fever can result in...
Acute Coronary Syndrome I: Introduction
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...
Acute Coronary Syndrome III: Diagnostic Studies
Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
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...
Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
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...
