A Late Diagnosis of Transthyretin Amyloidosis

Area of Science:

• Cardiology
• Cardiovascular Diseases
• Amyloidosis

Background:

• Cardiac amyloidosis involves abnormal protein fibril deposition in the heart muscle.
• This deposition leads to myocardial stiffening, reduced cardiac compliance, and diastolic dysfunction.
• Systolic function is typically preserved until later stages of the disease.

Observation:

• Presents a clinical case of advanced transthyretin-related amyloidosis (ATTR).
• ATTR amyloidosis is a progressive infiltrative cardiomyopathy.
• The disease progresses to affect systolic function in its late stages.

Findings:

• ATTR amyloidosis can lead to significant cardiac dysfunction.
• Late-stage disease progression affects the heart's ability to pump blood effectively.
• The case underscores the importance of early diagnosis and management.

Implications:

• Highlights the clinical presentation and progression of late-stage ATTR amyloidosis.
• Emphasizes the need for timely diagnosis to prevent irreversible cardiac damage.
• Informs clinical practice regarding the management of infiltrative cardiomyopathies.
