Awareness, attitudes, and barriers toward Transthyretin Amyloid Cardiomyopathy in Latin America: A questionnaire-based cross-sectional study

Abstract

Background: Cardiac Amyloidosis (CA), specifically Transthyretin Amyloid Cardiomyopathy (ATTR-CM), is an under-recognized, progressive, and fatal disease. Comprehensive primary data describing awareness, attitudes, and barriers to treatment in Latin America (LATAM) are lacking, highlighting a gap between guidelines and real-world clinical practice.

Methods: A cross-sectional, questionnaire-based observational study was conducted among 470 physicians actively involved in patient management across 8 LATAM countries (June-August 2023). The study assessed their awareness, attitudes, and barriers concerning ATTR-CM. Descriptive analysis was performed.
