APOA1 and acute coronary syndrome: Prior studies have showed that decreased Apo-A1 levels are closely associated with increased risk of coronary artery disease, stroke, and acute coronary syndrome.16-18 Besides that, in a small study included only 11 female patients, Kim et al demonstrated that patients with PAF had an approximately 30% lower expression of Apo-A-1 compared to the healthy subjects.15 The present study, which was conducted in a larger sample size compared to the abovementioned study, also found that not only female PAF patients but also male PAF patients had lower Apo-A1 levels than healthy subjects.
