In 1980, a reported pattern of<unk><unk> s was brought to the attention of the Centers for Disease Control. The first reported<unk><unk>  occurred in 1948 when there were 81 similar<unk> s of Filipino men in Oahu County, Hawaii. However, it did not become relevant because there was no associated pattern. This syndrome continued to become more significant as years went on. By 1981–1982, the annual rate in the United States was high with 92/100,000 among Laotians-Hmong, 82/100,000 among other Laotian ethnic groups, and 59/100,000 among Cambodians. In a 2008 study it was found that over half of SADS<unk> s could be attributed to inherited heart disease: unexplained premature<unk><unk> s in family, long QT syndrome, Brugada syndrome, arrhythmogenic right ventricular cardiomyopathy and others. Asia Southeast Asian immigrants, who were mostly fleeing the Vietnam War, most often had this syndrome, marking Southeast Asia as the area containing the most people with this fatal syndrome. However, there are other Asian populations that were affected, such as Filipinos and Chinese immigrants in the Philippines, Japanese in Japan, and natives of Guam in the United States and Guam. Nonetheless, these particular immigrants who had this syndrome were about 33 years old and seemingly healthy and all but one of the Laotian Hmong refugees were men. The condition appears to affect primarily young Hmong men from Laos (median age 33) and northeastern Thailand (where the population are mainly of Laotian descent).
