Key result
In 30 patients with cardiac amyloidosis, 100% had echocardiographic signs of restrictive cardiomyopathy, 63% had low-voltage ECGs, and 67% died at a mean of 232 days after diagnosis.

What are the key ECG and echocardiographic features for early diagnosis of cardiac amyloidosis?
Accurate ECG evaluation and careful echocardiographic assessment including strain imaging are crucial for the early diagnosis of cardiac amyloidosis, which carries a poor prognosis.
Piper et al. (2010) conducted an observational in Cardiac amyloidosis (n=30). ECG, tissue Doppler echocardiography, and myocardial biopsy was evaluated on Diagnostic features and mortality. In 30 patients with cardiac amyloidosis, 100% had echocardiographic signs of restrictive cardiomyopathy, 63% had low-voltage ECGs, and 67% died at a mean of 232 days after diagnosis.
