Background:
Pericardial effusion is associated with amyloidosis, specifically amyloid light chain (AL) and transthyretin (ATTR) subtypes. However, the patients might present with different clinical symptoms.
Objective:
To determine the characteristics and associations of patients with pericardial effusion owing to either AL or ATTR amyloidosis.
Methods:
This study reviewed 26 studies from databases such as PubMed, MEDLINE, Web of Science, Google Scholar and CINAHL databases after protocol registration. The data were analyzed in IBM SPSS 21. Many statistical tests, such as Student t- and the Mann-Whitney U tests, were used. Multivariate logistic regression analysis was also performed. A p-value< 0.05 was considered significant.
Results:
A total of 531 patients with pericardial effusion secondary to amyloidosis were included. The mean age was 58.4±24.5 years. Most of the patients were male (72.9%). Common co-morbid conditions included hypertension (16.8%) and active smoking (12.9%). The most common time from symptom onset to the clinical presentation was less than 1 week (45%). ATTR amyloidosis was more common in older patients (p<0.05). Abdominal and chest discomfort were commonly associated with AL and ATTR amyloidosis, respectively (p<0.05). Patients with AL amyloidosis had a higher association with interventricular septal thickening and increased posterior wall thickness (p<0.05). First-degree atrioventricular block, left bundle branch block (LBBB), and atrial fibrillation (AF) were more associated with ATTR amyloidosis (p<0.05).
Conclusion:
Pericardial effusion in patients with AL amyloidosis was associated with hypertrophic remodeling, while conduction abnormalities were associated with ATTR amyloidosis.
