The APO A-1 to B ratio was inversely associated with both myocardial infarction and stroke and may be an important protective clinical marker for atherosclerosis.
In our case-control study (1013 cases; 1029 controls), the OR for a first ischemic stroke was 0.83 (0.74-0.92), 1.33 (1.18-1.48) and 2.10 (1.76-2.51), respectively, with increased ApoA1 level associated with hemorrhagic stroke (1.37 [1.06-1.78]).
Adjustments were made for: age; gender; history of stroke and hypertension; systolic blood pressure; lipid-lowering, antiplatelet and antihypertensive medications; laboratory profiles including hemoglobin, serum albumin, calcium, triglyceride, total and low-density lipoprotein cholesterol; and apolipoprotein A1.
