Data collection
A quick response (QR) code was created to facilitate the process of recruiting cardiologists in the survey. The QR code was initially released at the 20th CHRS scientific sessions in August 2020 and circulated via several social media platforms targeting cardiologists in the following 4 months. After scanning the QR code, participants would be guided to the survey website for eligibility assessment. The questionnaire would launch after the participant providing informed consent.
