ECG findings and routine laboratory parameters of 173 hospital in-patients aged 90 or older with and without senile cardiac amyloidosis were studied. All patients underwent autopsy. No statistical association could be observed between ECG findings and the presence of senile cardiac amyloidosis at autopsy. Routine serum studies appeared to offer no substantial aid in the diagnosis of this disease. This observation has clinical relevance, in view of the high incidence and clinical severity of senile cardiac amyloidosis in the older population.
