What are the unmet needs and challenges related to the use of implantable cardioverter-defibrillators for primary prevention of sudden cardiac death in Asia?
This review highlights the critical unmet needs and lack of randomized trial data regarding the use of ICDs for primary prevention of sudden cardiac death in Asian populations.
The effectiveness of primary prevention implantable cardioverter-defibrillators (ICDs) is well established. However, there are several unsolved problems related to ICD use for primary prevention in Asia, including ICD underuse, population differences in underlying heart disease, and the rate of appropriate ICD therapy compared with Western countries. Although the prevalence of ischemic cardiomyopathy in Asia is lower than in Europe and the United States, the mortality rate of Asian patients with ischemic heart disease has been increasing recently. As for the use of ICDs for primary prevention, there have been no randomized clinical trials, and limited data are available in Asia. This review focuses on the unmet needs related to ICD use for primary prevention in Asia.
