title: Familial Hypercholesterolemia in Asian Populations.
abstract: Familial hypercholesterolemia (FH) is the most common autosomal disorder characterized by an elevated low-density lipoprotein-cholesterol level and a high risk of premature cardiovascular disease. In this review, we summarize information on FH studies in Asian countries, focusing on mean cholesterol level, FH frequency, diagnostic criteria, genotypes, and clinical care of FH patients in Asian populations. Compared with Western countries, most Asian countries had lower mean cholesterol levels, with a significant variation between different countries. In the limited studies reported, a frequency of 1/900 was reported in Hokuriku district, Japan in 1977 and a frequency of 1/85 among Christian Lebanese in 1979. Recently, a population study in China reported frequencies of 0.47% and 0.28%. However, the different FH frequencies reported were based on different diagnostic criteria. Of 28 publications from 16 Asian countries or regions, 14 used self-defined FH criteria. Only one specific guideline for FH was available, which was developed by Japanese scientists. Six Asian countries joined the Make Early Diagnosis to Prevent Early Deaths program in the late 1990s, and the estimated diagnosis rates of FH ranged from 3% to 10% in these countries. A more recent study explored the awareness, knowledge, and perception of FH among practitioners in Japan, Korea, and Taiwan. The study found that the correct rates of these FH-related questions were low and concluded that lack of country-specific criteria and guidelines may contribute to the lack of FH knowledge in the present survey. More attention and resources should be focused on raising awareness, improving care, and increasing FH research in Asian populations.
