Cardiac involvement in Churg-Strauss syndrome mimicking acute coronary syndrome

Area of Science:

• Cardiology
• Rheumatology
• Internal Medicine

Background:

• Churg-Strauss syndrome (CSS) is a rare, multisystemic vasculitis with unknown etiology.
• Cardiac involvement is a severe manifestation of CSS, contributing to approximately 50% of CSS-related mortality.
• CSS can present with acute cardiac symptoms that resemble acute coronary syndrome (ACS).

Observation:

• Cardiac manifestations in CSS can be acute and clinically mimic ACS.
• Hypereosinophilia, an elevated eosinophil count in the blood, is a key hematological finding in CSS.
• Prompt recognition of these features is vital for timely diagnosis and management.

Findings:

• The study highlights the critical role of cardiac involvement in CSS mortality.
• It emphasizes the diagnostic challenge posed by CSS cardiac presentations resembling ACS.
• Elevated leucocyte counts, specifically hypereosinophilia, serve as a crucial diagnostic clue for CSS.

Implications:

• Early identification of hypereosinophilia in patients with suspected cardiac events can lead to the diagnosis of CSS.
• This underscores the importance of a comprehensive diagnostic approach beyond typical cardiac workups.
• Timely diagnosis of CSS allows for appropriate immunosuppressive therapy, potentially reducing cardiac morbidity and mortality.
