Insights

A 15-year-old girl experienced ST-elevation myocardial infarction (STEMI) due to coronary thrombosis linked to COVID-19. This case highlights the need to consider myocardial infarction in pediatric COVID-19 patients with heart dysfunction.

Area of Science:

  • Pediatric Cardiology
  • Infectious Diseases
  • Cardiovascular Medicine

Background:

  • ST-elevation myocardial infarction (STEMI) is a known complication of COVID-19 in adults.
  • STEMI has not been previously reported in pediatric cases of COVID-19.
  • Multisystem inflammatory syndrome in children (MIS-C) is a recognized COVID-19-associated condition in children, but this case is distinct.

Observation:

  • A 15-year-old female presented with symptoms suggestive of myocardial infarction.
  • The patient was diagnosed with acute severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.
  • Clinical presentation included chest pain, ST elevation on electrocardiogram, and evidence of myocardial dysfunction.

Findings:

  • Coronary angiography revealed acute thrombosis in the coronary arteries.
  • The patient was diagnosed with ST-elevation myocardial infarction (STEMI) secondary to coronary thrombosis.
  • The STEMI was not associated with multisystem inflammatory syndrome in children (MIS-C).

Implications:

  • This case demonstrates that STEMI can occur in children infected with SARS-CoV-2.
  • Coronary thrombosis should be considered as a potential cause of STEMI in pediatric COVID-19 patients.
  • Clinicians should maintain a high index of suspicion for myocardial infarction in children presenting with cardiac dysfunction during COVID-19 infection.

Acute Coronary Syndrome I: Introduction01:30

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 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...

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...

Myocarditis: Comprehensive Medical ManagementMyocarditis, the heart muscle inflammation, requires a comprehensive medical management strategy that addresses the underlying cause, provides supportive care, manages symptoms, and reduces cardiac workload.Infections and Autoimmune CausesAdminister appropriate antimicrobial therapy when an infectious agent causes myocarditis. For instance, penicillin treats infections caused by Group A Streptococcus. In cases where autoimmune processes are...

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...
