title: [Lipoprotein (a), apolipoproteins and the lipid profile late after heart transplantation].
abstract: PURPOSE--To evaluate if the levels of lipoprotein (a) [Lp(a)], apolipoproteins (apo) A1, B and the lipid profile (LP) differ among heart transplantation (HT) patients, with coronary artery disease (CAD) and patients without CAD (NL) and if LP discriminates patients with graft vascular disease (GVD). METHODS--A hundred and seventy patients separated in 3 groups: I) HT [n = 43 46 +/- 15 years, 24 months (median) after transplantation], of these 28 were submitted to serial angiography after the first year of transplantation subgroups with GVD (n = 9) and without GVD (NGVD) (n = 19); II) CAD (n = 72, 48 +/- 6 years); III) NL (n = 45, 50 +/- 6 years). RESULTS--HT presented higher apo A1 levels than CAD and NL (1.5 +/- 0.5 vs 1.2 +/- 0.05 vs 1.1 +/- 0.06 g/l p < 0.05 respectively). Apo B was higher on CAD than in HT and NL (1.5 +/- 0.05 vs 1.2 +/- 0.07 vs 1.3 +/- 0.09 g/l p < 0.05). Lp (a) presented a trend to higher levels in HT and CAD than in NL [25(2-97), 24(1-130) and 15 (1-100) mg/dl, p = 0.05)]. However, when individually evaluated against NL Lp(a) levels were higher in HT and CAD (p = 0.019 and 0.03 respectively). LP did not differ between GVD and NGVD. CONCLUSION--Increased Lp(a) levels after transplantation might be related to the high prevalence of GVD. The LP did not discriminate GVD.
