Abstract:
Objective:To assess the current clinical application status of provocation/stress echocardiography in hypertrophic cardiomyopathy（HCM）among echocardiography physicians from large grade A tertiary hospitals，located in 24 provinces or directly administered municipalities，and to achieve a relatively clear and comprehensive overview of the current clinical application status of provocation/stress echocardiography in HCM. This study was conducted by the Chinese Society of Ultrasound in Medicine（CSUM）and Chinese Society of Echocardiography（CSE）.Methods:An online survey was anonymously conducted using Question Star application from 20 March to 30 September 2023. The survey covered the following topics including the echocardiographic diagnostic overview，the selection of views and measurement parameter of echocardiography，and the cognition and application，awareness and management of risk，and clinical demand of provocation/stress echocardiography.Results:A total of 337 valid responses were included in the final statistical analysis. The study revealed that the number of HCM patients seen by echocardiography physicians was very few（0-10%），with a low proportion of diagnosed obstructive HCM patients. There was incomplete mastery of the left ventricular outflow tract（LVOT）obstruction criteria（68.25%），insufficient awareness of the importance of LVOT pressure gradient measurement（7.12% echocardiographic doctors routinely performed LVOT gradient measurement for suspect HCM patients），non-standardized selection of echocardiographic views and measurement parameters for HCM，and significant deficiencies in knowledge and application of Valsalva provocation/stress echocardiography（17.21% and 79.23% doctors were quite aware of the principles of Valsalva provocation/stress echocardiography，respectively）. The risk awareness of provocation/stress echocardiography（13.65% physicians were fully aware of the potential risk）and the ability to manage associated risks（19.29% physicians were able to handle all emergencies）were lacking. Existing guidelines did not sufficiently standardize the clinical practice of provocation/stress echocardiography（23.44%），and there was diversity in learning formats requirements and unmet clinical needs.Conclusions:This survey revealed insufficient fundamental theoretical knowledge and a need for further standardization and training in the application of provocation/stress echocardiography for HCM among echocardiography physicians. Additionally，risk awareness and adequate response skills need improvement. There is a need for more practical and guiding guidelines for clinical practice，as well as numerous unmet clinical needs.
