Angina pectoris in a child with sickle cell anemia
Pediatrics
|June 1, 1978
Summary
Sickle cell disease patients may experience angina after stopping blood transfusions. Transfusions can alleviate exercise-induced chest pain and ECG changes in these children.
Area of Science:
- Pediatric Cardiology
- Hematology
- Cardiovascular Medicine
Background:
- Sickle cell disease (SCD) is a genetic blood disorder requiring management strategies like hypertransfusion therapy.
- Wolff-Parkinson-White syndrome (WPW) is a cardiac accessory pathway condition.
- Left ventricular dysfunction can be a complication in pediatric patients with chronic conditions.
Observation:
- A 7-year-old boy with SCD, WPW, and mild left ventricular dysfunction presented with angina pectoris.
- Symptoms of angina and exercise-induced ST segment depression on ECG emerged five months after discontinuing hypertransfusion therapy.
Findings:
- Angina and associated ECG abnormalities resolved after the reinitiation of transfusion therapy.
- This suggests a direct link between transfusion status and cardiac ischemia in this patient.
Implications:
- Hypertransfusion therapy may play a role in preventing or managing cardiac ischemia in select pediatric patients with SCD.
- Further research is warranted to understand the mechanisms linking SCD, transfusion therapy, and cardiac events.
- This case highlights the importance of monitoring cardiac function and considering transfusion protocols in children with SCD and coexisting cardiac conditions.

01:19Acute Coronary Syndrome II: Pathophysiology and Clinical Manifestations
The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...
01:30Angina 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...
01:27Angina 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...
01:29Angina 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...
01:26Angina IV: Management
IntroductionThe management of angina requires a comprehensive approach that includes pharmacological therapies, medical procedures, and lifestyle modifications.Pharmacological TherapiesAntiplatelet agents, such as aspirin, clopidogrel, prasugrel, and ticagrelor, play a pivotal role in preventing thrombus formation in patients with angina. These medications inhibit platelet aggregation and reduce the likelihood of myocardial infarction and other cardiovascular events.Anticoagulants, including...
01:20Angina 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...
