[The clinical features and outcomes of immunoglobulin light-chain amyloidosis with heart involvement].

ABSTRACT

OBJECTIVE: To analyze the clinical features and outcomes of patients with immunoglobulin light-chain amyloidosis (AL) who had heart involvement. METHODS: Clinical features and outcomes of AL amyloidosis patients with heart involvement in the past 7 years in our hospital were retrospectively analyzed. RESULTS: Cardiac involvement was seen in 36 out of the 60 AL patients (60%). The clinical manifestations of cardiac amyloidosis included heart failure (50%), low QRS voltage (47.2%) and pseudomyocardial infarction (33.3%) in electrocardiography, as well as thickening of ventricular wall (63.9%), echo of granular sparkling texture (11.1%), atria dilation (33.3%) and diastolic dysfunction (30.6%) in echocardiography. The prognosis was poor, with a median survival time of 13.9 months. CONCLUSION: Patients of AL amyloidosis with cardiac involvement are not rare. Thickening of ventricular wall and diastolic dysfunction are the most common characteristics. Special attention should be paid to this disease.
