OBJECTIVE--To assess whether lipoprotein(a) [Lp(a)] is a risk factor for
atherosclerotic cardiovascular disease in diabetes. RESEARCH DESIGN AND
METHODS--We studied 221 patients with non-insulin-dependent diabetes
mellitus (NIDDM) without diabetic complications who were followed for
2.2-3.1 years. Their serum Lp(a) levels were semiquantified by a rapid
electrophoretic method that accurately discriminates high from low serum
Lp(a) at the 20 mg/dl level. RESULTS--Seven of 105 diabetic patients with a
high serum Lp(a) experienced a clinical event related to atherosclerotic
cardiovascular disease. This incidence was significantly higher than that
of the 110 diabetic patients with a low serum Lp(a). The logistic
regression analysis revealed that Lp(a) was an independent risk factor for
the event. CONCLUSIONS--Lp(a) is a significant risk factor for
atherosclerotic cardiovascular disease in NIDDM.
