OBJECTIVETo investigate the eGFR as a risk factor for long-term (4-year) outcome in Chinese renal insufficiency patients after isolated coronary artery bypass grafting (CABG) at our institution.

METHODSFrom January 1999 to September 2003, 3371 consecutive patients who underwent isolated CABG were retrospectively reviewed. Of these patients, 549 (16.29%) patients were female, 1979 (58.71%) patients with hypertension, 866 (25.69%) patients with diabetes, 1130 (33.52%) patients with hyperlipidemia, 1011 (29.99%) patients with left main stenosis > 50%, and 1150 (34.11%) patients undergoing off-pump procedures. The mean age was (60 +/- 9) years old. Estimated GFR was calculated using the Cockcroft-Gault formula. The main outcomes were in-hospital mortality, in-hospital morbidity and long-term mortality. COX analysis was used in this study.

RESULTSThere were 649 patients with glomerular filtration rate estimates < 60 ml/(min.1.73 m(2)) and 2722 patients with glomerular filtration rate estimates > 60 ml/(min.1.73 m(2)). The in-hospital mortality and follow-up mortality was higher in the estimated glomerular filtration rate < 60 ml/(min.1.73 m(2)) group (2.77% vs. 0.77%, P < 0.01), (6.81% vs. 2.63%, P < 0.01). The COX analysis result confirmed eGFR < 60 ml/(min.1.73 m(2)), derived using the Cockcroft-Gault formula (HR: 1.948, 95%CI: 1.357 to 2.797, P < 0.01) was an independent risk factor for long-term mortality in patients after coronary artery bypass grafting surgery.

CONCLUSIONSThe estimated glomerular filtration rate < 60 ml/(min.1.73 m(2)) derived using the Cockcroft-Gault formula is an independent risk factor for long-term mortality in patients after coronary artery bypass grafting surgery.

AIMTo study the chemical constituents of the stems and leaves of Aconitum coreanum (Lèvl.) Rapaics.

METHODSThe constituents of Aconitum coreanum were isolated by using various kinds of modern chromatographic methods. The new alkaloid was identified on the basis of spectral analysis.

RESULTSTwo compounds were isolated and identified as: 13-dehydro-1beta-acetyl-2alpha,6beta-dihydroxyhetisine (I) and Guanfu base G (II).

CONCLUSIONCompound I is a new alkaloid.

OBJECTIVETo compare the predictive value of glomerular filtration rate (GFR) estimated by the Cockcroft-Gault formula or the modification of diet in renal disease (MDRD) equation and serum creatinine for in-hospital and long-term mortality post coronary artery bypass graft surgery (CABG).

METHODSClinical data of 5559 consecutive patients undergoing isolated CABG were retrospectively analyzed. The main outcomes were in-hospital mortality and long-term mortality. Estimated GFR was calculated by the Cockcroft-Gault formula and MDRD equation respectively. Receiver-operating characteristic curves and Cox's analysis were used for the comparison.

RESULTSFollow-up was complete in 5485 patients (97.6%). Analysis of receiver-operating characteristic curves showed that GFR estimated by the Cockcroft-Gault formula had a maximal accuracy for predicting in-hospital mortality (area under the curve: 0.755, P < 0.01). Multivariate logistic analysis and the Cox's analysis results indicated estimated GFR < 60 mlxmin(-1)x1.73 m(-2) base on the Cockcroft-Gault formula was an independent risk factor for in-hospital and long-term mortality (hazard ratio 4.51 for in-hospital mortality, P < 0.01; hazard ratio 1.54 for long-term mortality, P < 0.01), both Cockcroft-Gault formula and MDRD equation were superior to serum creatinine for predicting in-hospital and long-term mortality post CABG.

CONCLUSIONGFR estimated by the Cockcroft-Gault formula was superior to GFR estimated by the MDRD equation for predicting in-hospital mortality, and estimated GFR was superior to serum creatinine for predicting in-hospital and long-term mortality.

OBJECTIVETo determine independent factors correlated with clinical effects of DK crush and classical crush technique with drug-eluting stents on bifurcation lesions.

METHODS311 patients with bifurcation lesions were randomized to classical (C, n = 156) or double kissing (DK) crush (n = 155) stent implantation group. The primary endpoints included major adverse cardiac events (MACE).

RESULTSFinal kissing balloon inflation (FKBI) success rate was 76% in C and 100% in DK groups (P < 0.001). DK crush procedure was characterized by lower unsatisfactory FKBI rate (27.6% vs.6.3%, P < 0.01). Clinical follow-up was available in 100% and angiographic follow-up in 82% patients. The overall restenosis rate was 32.3% in C and 20.3% in DK groups (P = 0.01), respectively. Cumulative 8-month MACE was 35.9% in without-FKBI and 19.7% in with-FKBI sub-groups, and 11.4% in DK group (P = 0.02). The incidence of stent thrombosis was 3.2% in C group (5.1% without vs. 1.7% with FKBI) and 1.3% in DK group (P > 0.05). The predictive factors of MACE included minimal side branch stent lumen diameter and lack of DK crush technique.

CONCLUSIONDK crush technique is an alternative of double stenting techniques in terms of improvement of restenosis and clinical outcomes.
