[Clinical and instrumental findings in cardiac amyloidosis]
Insights
Cardiac amyloidosis presents with varied symptoms, often leading to misdiagnosis. This study highlights key clinical, electrocardiographic, and echocardiographic findings in two male patients, emphasizing the need for increased awareness of this condition.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Cardiac amyloidosis is a progressive disease characterized by amyloid protein deposition in the heart.
- It can lead to heart failure and arrhythmias, often presenting with non-specific symptoms.
Observation:
- Two male patients, aged 58 and 60, presented with congestive heart failure.
- Both exhibited abnormal electrocardiograms and echocardiographic findings including increased myocardial echogenicity, ventricular hypertrophy, pericardial effusion, and reduced ventricular function.
Findings:
- Biopsies (rectal and endomyocardial) were positive for amyloid in both patients.
- The study confirms that clinical manifestations of cardiac amyloidosis are diverse and frequently overlooked.
Implications:
- Increased clinical suspicion and diagnostic vigilance are crucial for early identification of cardiac amyloidosis.
- Timely diagnosis can potentially improve patient outcomes through appropriate management strategies.
Abstract:
The clinical findings of 2 male patients, aged 58 and 60 years with cardiac amyloidosis are described. Congestive heart failure was present in both. Electrocardiograms were abnormal in both cases. Echocardiographic examination showed increased myocardial echogenicity and ventricular hypertrophy, pericardial effusion and decreased ventricular function. Cardiac catheterization was performed in 1 patient. Rectal biopsies were obtained from both patients; endomyocardial biopsy was executed in only 1 patient; all specimens were positive. Our data demonstrate, in agreement with the literature, that clinical features of cardiac amyloidosis are polymorphous and therefore often unidentified.
