ABSTRACT
Transthyretin cardiac amyloidosis (ATTR-CA) is characterised by the deposition of transthyretin amyloid fibrils in the heart. ATTR-CA affects both men and women although there is evidence of sex differences in prevalence and clinical presentation. PURPOSE OF REVIEW This review paper aims to comprehensively examine and synthesise the existing literature on sex differences in ATTR-CA. RECENT FINDINGS:
The prevalence of ATTR-CA is higher in males although the male predominance is more apparent in older patients in the wild type form and in TTR genetic variants that predominantly result in a cardiac phenotype in the hereditary variant. Women tend to have less left ventricular hypertrophy (LVH) and a higher ejection fraction at clinical presentation which may contribute to a later diagnosis although the prognosis appears to be similar in both sexes. Female sex is a predictor of a good response to tafamidis 20 mg in TTR polyneuropathy but otherwise there are no data on sex differences in the efficacy of other treatments for ATTR-CA. It is crucial to define specific sex differences in ATTR-CA. A lower cut-off value for LVH in women may be needed to improve diagnosis. It is necessary to increase female representation in clinical trials to better understand possible sex differences in therapeutic management.Palabras clave
