Lipoprotein(a) as a strong indicator for cerebrovascular disease.

To evaluate the role of lipoprotein(a) (Lp(a] in patients with cerebrovascular disease (CVD), lipid parameters were compared with a control group (CO). Additionally, the Lp(a) serum levels were investigated in a coronary artery disease (CAD) group. The CO was made up of 37 healthy persons (age: 54.5 +/- 7.7, 26 males and 11 females), the CVD group included 46 patients with sustained transient ischemic attack (TIA) prolonged reversible ischemic neurologic deficits (PRIND) and cerebral infarction (CI) (age: 53.6 +/- 9.7, 32 males and 14 females), and the CAD group was made up of 28 survivors of myocardial infarctions (age: 52.5 +/- 8.1, 18 males and 10 females). The median values of Lp(a) in CVD were significantly higher than in the CO (p less than 0.01) and did not differ significantly from the CAD. Total TC, HDL-C, TG, LDL-C and the ratio of LDL-C/HDL-C did not show any significant difference between the control and cerebrovascular disease group. For quantification of the vascular lesions of the carotid system, a Duplex Doppler score system was used. The score correlated with Lp(a) in patients between 40 to 65 years of age (r = 0.34, p less than 0.01). Thus, we conclude that Lp(a) is not only a risk factor for CAD but also for CVD.
