Summary

Systemic amyloidosis can cause heart failure, even in patients without typical risk factors. Early diagnosis is crucial for managing this rare but serious condition.

Area of Science:

  • Cardiology
  • Nephrology
  • Internal Medicine

Background:

  • Congestive heart failure (CHF) management can be challenging, particularly in cases refractory to standard diuretic therapy.
  • Cardiac involvement in systemic amyloidosis is a recognized but often overlooked cause of heart failure.

Observation:

  • An 82-year-old woman with diuretic-refractory CHF was diagnosed with systemic amyloidosis via rectal biopsy.
  • Her presentation included heart failure with preserved ventricular systolic function, without evidence of ischemic heart disease or hypertension.

Findings:

  • Systemic amyloidosis can mimic other forms of heart failure, leading to diagnostic delays.
  • Rectal biopsy is an effective method for confirming systemic amyloidosis.

Implications:

  • Clinicians should consider systemic amyloidosis in the differential diagnosis of heart failure, especially with preserved ejection fraction and atypical risk factors.
  • Increased clinical suspicion and awareness are vital for early detection and improved management of this life-threatening condition.
