Abstract:
Background: Familial hypercholesterolemia (FH) increased risk of premature atherosclerosis. Currently, data on the prevalence of FH among patients with premature acute coronary syndrome (ACS) patients in Thailand are limited. Objective: This study aimed to evaluate the prevalence of FH among patients with premature ACS patients undergoing coronary angiography between January 2017 and January 2021 at King Chulalongkorn Memorial Hospital (KCMH). Method: A total of 143 patients with premature ACS were assessed for FH using the Dutch Lipid Clinical Network (DLCN) criteria. Patients who had DLCN score ≥ 6 (probable FH for score 6-8 or definite FH for score > 8) were considered having FH. Other CV risk factors known to cause CAD such as smoking, diabetes mellitus, and hypertension were also recorded. Results: Of total 143 patients with premature ACS, 9 (6.3%) were diagnosed as definite FH and 11 (7.7%) as probable FH, resulting in the prevalence of FH (probable or definite) of 14%. Conclusion: The prevalence of FH is high among patients with premature ACS. These findings show the importance of detecting FH among patients with premature ACS.
