OBJECTIVETo investigate the correlation between vascular remodeling index (RI) and serum adiponectin, plasma monocyte chemoattractant protein-1 (MCP-1), endothelial function and evaluate the mechanism of coronary in-stent restenosis.

METHODSRI 6 months after percutaneous coronary intervention (PCI), serum adiponectin, plasma MCP-1 and flow-mediated dilation (FMD) before and 3 days,6 months after PCI were measured in 30 patients with and 30 without coronary in-stent restenosis.

RESULTSCompared with patients without restenosis and those with restenosis before PCI, the patients with coronary in-stent restenosis showed significantly increased plasma MCP-1 3 days and 6 months after PCI (P<0.05) and reduced RI 6 months after PCI, serum adiponectin and FMD 3 days and 6 months after PCI (P<0.05). RI was positively correlated to serum adiponectin and FMD and inversely to MCP-1.

CONCLUSIONThe occurrence of coronary in-stent restenosis is the result of the interrelations between multiple factors.

Elevated intraocular pressure (IOP) is one of the major risk factors for glaucomatous visual field defects. Each individual systemic risk factor of coronary heart disease (CHD) is associated with elevated IOP, although no reports have argued for a correlation between the risk factors for CHD and IOP after a comprehensive or collective analysis. The National Cholesterol Education Program Adult Treatment Panel III presented the Framingham projection, which can predict the risk of CHD quantitatively. We investigated the association between IOP and the Framingham projection in 16,383 Korean subjects. The Framingham projection was applied using the indicated risk factors. The associations between the Framingham projection and IOP and the influences of the risk factors on the IOP were examined. The Framingham projection was correlated with the mean IOP in women (p<0.05). The relationship between IOP and systemic variables other than smoking was significant (p<0.05). The mean IOP was significantly higher in the high-risk CHD group than in the low-risk group based on the Framingham projection (p<0.05). Because an elevated IOP was associated with cardiovascular risk factors, subjects with a high CHD risk based on the Framingham projection need continuous monitoring for IOP to prevent glaucomatous visual field defects.

BACKGROUNDThe role of chronic hyperglycaemia as a coronary artery disease (CAD) risk factor is well-known, and the glycemic variability is still a matter of debate. The aim of this study was to investigate the association of admission glycemic excursion and hemoglobin A(1c) (HbA(1c)) with the presence and severity of CAD in patients with undiagnosed diabetes mellitus (DM).

METHODSWe studied 286 newly diagnosed DM patients without prior revascularization undergoing coronary angiography for suspected ischaemic chest pain. Patients were grouped into those with CAD and without CAD according to angiographic results. The severity of CAD was assessed using the Gensini score. Glycemic variability, indicated as the mean amplitude of glycemic excursions (MAGE), was determined by a continuous glucose monitoring system. Serum levels of HbA(1c) and high-sensitive C-reactive protein (hs-CRP) as well as plasma concentrations of fasting glucose, lipids and creatinine were measured in all patients. Predictors of CAD were determined using multivariate Logistic regression model and receiver-operating characteristic (ROC) curves.

RESULTSThe newly diagnosed DM patients with CAD were older, and more were male and current cigarette smokers compared with the patients without CAD. The CAD group had significantly higher levels of MAGE and HbA(1c). Individuals with high levels of HbA(1c) (≥ 7%) or MAGE (≥ 3.4 mmol/L) had also significantly higher CAD prevalence. Logistic regression analysis revealed that high MAGE level and high HbA(1c) level were independent predictors for CAD. The area under the receiver-operating characteristic curve for MAGE (0.606, P = 0.005) was superior to that for HbA(1c) (0.582, P = 0.028). Gensini score closely correlated with age, MAGE, HbA(1c), hs-CRP, creatinine and total cholesterol. Multivariate analysis indicated that age (P < 0.001), MAGE (P < 0.001), HbA(1c) (P = 0.022) and hs-CRP (P = 0.005) were independent determinants for Gensini score.

CONCLUSIONSBoth admission glycemic excursion and chronic hyperglycaemia are associated with the severity of CAD in newly diagnosed DM patients. MAGE displays a significant value in predicting CAD in patients with undiagnosed diabetes even more than HbA(1c).

OBJECTIVETo study the effect of Yiqi Wenyang Huoxue Lishui principle (YWHL, a therapeutic principle with Chinese medicine for reinforcing Qi warming Yang, activating blood circulation and promoting urination) on some neuroendocrine factors in patients with congestive heart failure (CHF).

METHODSForty-nine patients of CHF with heart function of grade III-IV were randomly divided into 2 groups. The 29 cases in the treated group were treated with YWHL and the 20 cases in the control group treated with captopril. Changes of angiotensin II (AT II), atrial natriuretic peptide (ANP), endothelin (ET), nitric oxide (NO) and alpha-granule membrance protein -140 (GMP-140) were observed.

RESULTSAfter treatment, plasma level of AT II, ANP, ET, and NO lowered in both groups with insignificant difference, but the GMP-140 reduced more significantly in the treated group (P < 0.05).

CONCLUSIONYWHL showed a regulatory effect of neuroendicrine system partially similar to that of angiotensin-converting enzyme inhibitor, it possibly can improve the ventricular remodeling and would be beneficial to prevent the thrombus formation and improve heart failure by means of inhibiting platelet activity.

This was designed to assess the outcomes of side branch (SB) stenosis after implantation of three drug-eluting stents (DES). From 2,645 patients in the ZEST (Comparison of the Efficacy and Safety of Zotarolimus-Eluting Stent with Sirolimus-Eluting and PacliTaxel-Eluting Stent for Coronary Lesions) Trial, 788 patients had 923 bifurcation lesions with SB > or = 1.5 mm were included. SB was treated in 150 lesions, including 35 (3.8%) receiving SB stenting. Of untreated SB with baseline stenosis < 50%, the incidences of periprocedural SB compromise was similar in the zotarolimus (15.8%), sirolimus (17.2%), and paclitaxel (16.6%) stent groups (P = 0.92). At follow-up angiography, delayed SB compromise occurred in 13.9%, 3.2%, and 9.4% (P = 0.010) of these groups. When classified into four groups (< 50%, 50%-70%, 70%-99%, and 100%), 9.0% of untreated SB were worsened, whereas improvement and stationary were observed in 9.6% and 81.4%. In a multivariable logistic regression model, main branch (MB) stenosis at follow-up (%) was the only independent predictor of SB stenosis worsening (odds ratio, 1.03; 95% confidence interval, 1.01-1.04; P < 0.001). After MB stenting in bifurcation lesions, a minority of SB appears to worsen. DES with strong anti-restenotic efficacy may help maintain SB patency.

OBJECTIVEThe study was designed to investigate the clinical characteristics and the effects of therapeutic proposal on Kawasaki disease (KD).

METHODSClinical features, diagnosis and treatment for totally 942 patients with KD hospitalized during Jan, 2000 to Dec, 2004 were reviewed. Clinical features of typical and incomplete KD were compared. Also, influential factors for KD resistant to intravenous immune globulin (IVIG) therapy were analyzed. Five hundred and ten cases were followed up for analyzing the prognosis of coronary artery lesion (CAL).

RESULTS(1) 774 cases were diagnosed as typical KD, and 168 cases as incomplete KD. The incidence of infants with incomplete KD was higher than that of infants with typical KD (18.5% vs. 10.1%, P < 0.01). As compared with typical KD, the cases of incomplete KD had a long duration of fever before final diagnosis [(7.7 +/- 2.9) d vs. (7.0 +/- 2.4) d, P < 0.01], high hemoglobin level [Hb, (106.6 +/- 13.4) g/L vs. (103.5 +/- 12.3) g/L, P < 0.01], high hematocrit [Hct, (32.0 +/- 4.3)% vs. (31.0 +/- 4.0)%, P < 0.01], and high prevalence of CAL (23.8% vs. 16.8%, P < 0.05), respectively. The occurrence rate and emerging time of clinical manifestations in incomplete KD and in typical KD were presented, respectively: non-exudative conjunctivitis [occurrence rate, 64.9% vs. 93.5%; emerging time, (4.4 +/- 1.4) d vs. (4.0 +/- 1.6) d, respectively (P < 0.05 or P < 0.01)], erythema and cracking of lips [occurrence rate, 50.6% vs. 94.8%; emerging time, (4.9 +/- 1.4) d vs. (4.5 +/- 1.6) d, respectively (P < 0.05 or P < 0.01)], rash [occurrence rate, 35.1% vs. 87.7%; emerging time, (3.9 +/- 1.9) d vs. (3.4 +/- 1.7) d, respectively (P < 0.05 or P < 0.01)], erythema and edema of extremity [occurrence rate, 26.8% vs. 71.4%; emerging time, (6.7 +/- 1.5) d vs. (5.3 +/- 1.7) d, respectively (P < 0.01)], cervical lymphadenopathy [occurrence rate, 34.5% vs. 68.0%; emerging time, (4.3 +/- 2.5) d vs. (3.6 +/- 2.2) d, respectively (P < 0.05 or P < 0.01)], strawberry tongue [occurrence rate, 31.0% vs. 59.8%; emerging time, (5.6 +/- 2.2) d vs. (4.9 +/- 1.8) d, respectively (P < 0.05 or P < 0.01)], membranous desquamation of fingertips [occurrence rate, 34.5% vs. 56.3%; emerging time, (11.7 +/- 3.3) d vs. (10.3 +/- 2.7) d, respectively (P < 0.01)], and desquamation peri-anus [occurrence rate, 42.9% vs. 50.0%; emerging time, (6.7 +/- 2.7) d vs. (6.9 +/- 2.5) d, respectively (P > 0.05)]. Except for peri-anus desquamation, other clinical manifestations in incomplete KD were sporadical as compared to typical KD. (2) Six per cent (51/857) of cases were resistant to the IVIG therapy. As compared to the group responding to IVIG therapy, high prevalence of CAL (31.4% vs. 17.1%, P < 0.05), long fever duration [(10.6 +/- 3.9) d vs. (7.5 +/- 2.3) d, P < 0.01], low Hb level [(99.9 +/- 14.1) g/L vs. (104.3 +/- 12.4) g/L, P < 0.01], low Hct [(30.1 +/- 4.5)% vs. (31.2 +/- 4.0)%, P < 0.05], low platelet [PLT, (256.9 +/- 142.4) x 10(9)/L vs. (309.7 +/- 131.5) x 10(9)/L, P < 0.05], and low albumin level [ALB, (27.8 +/- 8.4) g/L vs. (33.5 +/- 6.7) g/L, P < 0.01] were found in the group resistant to IVIG therapy, respectively. (3) In patients who received IVIG 1 g/kg and 2 g/kg, the recovery rates from CAL were 83.1% and 89.7% (P > 0.05), respectively. The prevalence of CAL in those without CAL in acute and subacute stages was 0.9% and 3.5% (P > 0.05), respectively, during 2 year-follow-up period.

CONCLUSION(1) Infants appeared to have more chances to suffer from incomplete KD. Incomplete KD had high prevalence of CAL. The peri-anus desquamation might be an important clue for early diagnosis of incomplete KD. (2) In acute stage, the influential factors for KD resistance to IVIG therapy included prolonged fever, non-elevated PLT, and persistent decrease in Hb, Hct and ALB levels. (3) Children receiving IVIG 1 g/kg and 2 g/kg had the similar effects on recovery and prevention from CAL within the first two years after KD onset.
