The effect of apolipoprotein E gene polymorphism and Lp(a) levels on coronary artery disease with atrial fibrillation

ObjectiveTo explore the influence of apolipoprotein E (APOE) genotypes and blood lipid metabolism on coronary artery disease (CAD) with atrial fibrillation (AF).MethodsPatients with suspected CAD were consecutively enrolled and divided into groups with or without CAD and/or AF. Blood lipid levels and APOE genotypes were determined and analysed for associations with CAD and AF.ResultsA total of 2048 patients were included (400 patients without CAD or AF [controls], 126 patients without CAD but with AF, 1294 patients with CAD without AF, and 228 patients with CAD and AF). Age and lipoprotein (a) (Lp[a]) levels were significantly higher in patients with CAD and AF versus those with CAD without AF. Among patients with CAD, the E3/E3 genotype and ε3 allele frequencies were significantly lower in patients with AF than in those without AF, and the E4/E4 genotype and ε4 allele frequencies were significantly increased. Multivariate logistic regression revealed that increased Lp(a) levels and age were independent risk factors for AF in patients with CAD.ConclusionAmong patients with CAD, those with AF had increased age, ε4 frequencies and Lp(a) levels. Age and Lp(a) levels may be independent risk factors for AF in patients with CAD.     

Synthesis and Bio‐Evaluation of New 18F‐Labeled Pyridaben Analogs with Improved Stability for Myocardial Perfusion Imaging in Mice

To improve the stability of ¹⁸F‐labeled pyridaben analogs for myocardial perfusion imaging, three new analogs of pyridaben ([¹⁸F]FPTP2, [¹⁸F]FPTP‐P2, and [¹⁸F]FPTP‐P3) were synthesized with ‘side chain’ modifications. The radiolabeled tracers and corresponding non‐radioactive compounds were obtained by substituting tosyl group with ^18/19F. The effect of structure modification on myocardial targeting and physicochemical properties of new tracers were evaluated in vitro and in vivo. The total radiosynthesis time of these tracers was approximately 70–90 min with high decay‐corrected radiochemical yields (36–65%) and good radiochemical purity (> 98%). These lipophilic tracers exhibited obvious improved stability in water. Studies of their biodistribution in normal Kunming mice demonstrated that [¹⁸F]FPTP2 exhibited very high initial heart uptake (39.70 ± 2.81 %ID/g at 2 min after injection) and low background in the liver, blood, and soft tissues. The heart‐to‐liver, heart‐to‐lung, and heart‐to‐blood ratios were 3.59, 19.34, and 67.34 at 15 min postinjection, respectively. Favorable myocardial targeting property and remarkable improvement of stability of [¹⁸F]FPTP2 suggest that the substitution of the phenyl ‘sidechain’ with other non‐phenyl rings has no effect on the myocardial targeting property of ¹⁸F‐labeled pyridaben analogs.
