Angina I: Introduction

Angina I: Introduction

Definition and Symptoms: Angina (angina pectoris) is chest pain or discomfort caused by myocardial ischemia, which occurs when the heart muscle receives insufficient oxygen-rich blood. It typically manifests as pressing, squeezing, or crushing sensations in the chest and may radiate to the shoulders, arms, neck, jaw, or back.Primary Cause: In a healthy state, the coronary arteries can dilate (widen) to increase blood flow and meet the increased oxygen demand during physical activity or...

Angina II: Classification

Angina II: Classification

Angina, also known as angina pectoris, is a chest pain resulting from diminished blood flow to the heart muscle and is often a symptom of coronary artery disease. Angina presents several variants with distinctive attributes, etiologies, and therapeutic approaches. The main types of angina include stable, unstable, variant (Prinzmetal's), microvascular, intractable, and silent ischemia.Stable angina is caused by atherosclerosis, which leads to the formation of plaques that narrow the coronary...

Angina V: Nursing Management

Angina V: Nursing Management

Angina, a symptom of myocardial ischemia, requires a structured nursing management approach to ensure effective care and prevent complications like myocardial infarction. Comprehensive nursing care involves assessing, diagnosing, planning, implementing interventions, and evaluating outcomes, all tailored to the individual patient's needs.Patient AssessmentNursing assessment begins with a detailed subjective evaluation of symptoms, which typically include chest pain or pressure radiating to the...

Angina III: Clinical Manifestations and Assessment

Angina III: Clinical Manifestations and Assessment

Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...

Spinal Cord Injury ll: Pathophysiology

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...

Secondary Spinal Cord Injury llI: Pathophysiology

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...

Summary

Cervical angina, chest pain from cervical spine issues, can be caused by spinal cord infarction. This rare condition may affect the sympathetic nervous system, leading to symptoms like bradycardia.

Area of Science:

Neurology
Cardiology
Spinal Cord Medicine

Background:

Cervical angina is chest pain mimicking cardiac angina, originating from cervical spine disorders, often cervical spondylosis.
The sympathetic nervous system plays a role in cardiovascular regulation, with fibers originating from cervical and thoracic spinal cord segments.

Observation:

A 66-year-old man experienced chest pain and bilateral arm palsy.
Neurological exam revealed C7-T1 level deficits; MRI showed a spinal cord lesion, diagnosed as spinal cord infarction.
Severe sinus bradycardia was noted, improving over 5 weeks.

Findings:

Spinal cord infarction can disrupt sympathetic control, leading to bradycardia, particularly with cervical or high-thoracic lesions.
The patient's bradycardia suggested sympathetic system impairment at cervical and thoracic levels.
Cervical angina in this case was mediated via the sympathetic nervous system.

Implications:

This case highlights spinal cord infarction as a rare cause of cervical angina.
Understanding the neurological basis of cervical angina is crucial for accurate diagnosis and management.
Further research into the neuro-cardiac axis in spinal cord injuries is warranted.
