Similarly, findings from the Atherosclerosis Risk in Communities (ARIC) study and the Reasons for Geographic And Racial Differences in Stroke (REGARDS) cohort, which measured Lp(a) in Black and White individuals from the general population in the United States, suggested that higher Lp(a) plasma levels were associated with a 45% to 80% greater incidence of ischemic stroke, particularly in Black men and White women [6,10]. The gene discussed is LPA; the disease is stroke disorder.
