BACKGROUNDIt has been reported that increased red blood cell width (RDW) is a marker associated with the presence and adverse outcomes of various cardiovascular diseases. The aim of the present study was prospectively evaluate the severity of coronary artery disease (CAD) and RDW in a large Chinese cohort.

METHODSA total of 677 consecutive individuals who underwent coronary angiography due to the presence of angina-like chest pain and/or positive treadmill exercise test were enrolled in this study. All patients received coronary angiography and were then divided into two groups based on the results of coronary angiography (CAD group (n = 499) and control group (n = 178)). The clinical information including classical CAD risk factors and RDW were analyzed to identify their relationship to CAD. The severity of CAD was evaluated by Gensini score and its relationship with RDW was also analyzed.

RESULTSPatients with angiographic CAD had significantly elevated RDW levels compared with controls ((12.95 ± 0.77)% vs. (12.73 ± 0.83)%, P = 0.001). There was a significant positive correlation between RDW and the Gensini score (r = 0.37, P < 0.001). In multivariate Logistic regression analysis, RDW was demonstrated to be an independent predictor for both angiographic CAD (OR = 1.34, 95%CI: 1.02 - 1.77, P < 0.05) and for a higher Gensini score (> 13, OR = 2.23, 95%CI: 1.62 - 3.08, P < 0.001). In a receiver operating characteristic (ROC) curve analysis, an RDW value of 12.85% was identified as an effective cut-point in predicting the presence or absence of CAD with a sensitivity of 50.0% and a specificity of 65.2%.

CONCLUSIONRDW is associated with both presence of CAD and the severity of coronary stenosis, suggesting that it might be a readily available marker for the prediction of CAD and its severity.

Objective: To investigate the relationship between plasma level of pro-protein convertase subtilisin kexin type9 (PCSK9) and coronary artery calcification (CAC). Methods: A total of 380 consecutive chest pain patients without lipid-lowering therapy were enrolled. All patients received CT scan and coronary artery calcification (CAC) score measurement and were divided into 2 groups: CAC group, n=156 patients with CAC score>0 and Non-CAC group, n=224 patients with CAC score=0. CAC group was further classified in 3 subgroups as CAC score (1-100) subgroup, n=53, CAC score (101-400) subgroup, n=64 and CAC score>400 subgroup, n=39. Clinical data was collected, plasma levels of PCSK9 were measured in all patients and the relationship between PCSK9 and CAC score was investigated. Results: Plasma PCSK9 level in CAC group was higher than Non-CAC group (260.23±69.34) ng/ml vs (205.46±53.21) ng/ml, P<0.001; alone with CAC score increasing, PCSK9 level was elevating accordingly as in CAC score (1-100) subgroup, CAC score (101-400) subgroup and CAC score>400 subgroup, PCSK9 levels were (247.38±72.68) ng/ml, (264.87±57.63) ng/ml and (295.33±69.06) ng/ml respectively, all P<0.05. With adjusted traditional cardiovascular risk factors, multivariate regression analysis confirmed that plasma PCSK9 level was independently related to CAC score (β=0.584, P=0.002). In addition, the optimal cut-off value for PCSK9 predicting CAC was 228.58 ng/ml with sensitivity at 67% and specificity at 71%. Conclusion: Plasma PCSK9 level was related to CAC in chest pain patients without lipid-lowering therapy.

OBJECTIVE: To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI). METHODS: From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12. RESULTS: In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred. CONCLUSIONS GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI. (Registration No. ChiCTR1800014291).

OBJECTIVEAssessment of the comprehensive relationship among apolipoprotein CIII (apoCIII) levels, inflammation, and metabolic disorders is rare.

METHODSA total of 1455 consecutive patients not treated with lipid-lowering drugs and undergoing coronary angiography were enrolled in this cross-sectional study. A mediation analysis was used to detect the underlying role of apoCIII in the association of inflammation with metabolic syndrome (MetS).

RESULTSPatients with MetS showed higher levels of apoCIII [95.1 (73.1-131.4) vs. 81.7 (58.6-112.4) μg/mL, P < 0.001] and inflammatory markers [high sensitivity C-reactive protein, 1.7 (0.8-3.4) vs. 1.1 (0.5-2.2) mg/L; white blood cell count, (6.48 ± 1.68) vs. (6.11 ± 1.67) × 109/L]. The levels of apoCIII and inflammatory markers increased with the number of metabolic risk components (all P < 0.001). Furthermore, apoCIII levels were associated with virtually all individual MetS risk factors and inflammatory markers (all P < 0.05). Importantly, the prevalence of MetS in each metabolic disorder rose as apoCIII levels increased (all P < 0.05). Mediation analysis showed that apoCIII partially mediated the effect of inflammation on MetS independently from triglycerides.

CONCLUSIONPlasma apoCIII levels were significantly associated with the development and severity of MetS, and a role of apoCIII in the effect of inflammation on the development of MetS was identified.

OBJECTIVELow-density lipoprotein cholesterol (LDL-C) has been well known as the risk factor of coronary artery disease (CAD). However, the role of lipoprotein (a) [Lp(a)] in the development of CAD is of great interest but still controversial. Thus, we aim to explore the effect of Lp(a) on predicting the presence and severity of CAD in Chinese untreated patients, especially in combination with LDL-C.

METHODSWe consecutively recruited 1,980 non-treated patients undergoing coronary angiography, among which 1,162 patients were diagnosed with CAD. Gensini score (GS) was used to assess the severity of CAD. Lp(a) was measured by immunoturbidimetric method.

RESULTSPatients with CAD had higher level of LDL-C and Lp(a) compared with non-CAD (P < 0.05). Multivariable logistic regression revealed that Lp(a) > 205 mg/L (highest tertile) predicted 1.437-fold risk for CAD (95% CI: 1.108-1.865, P = 0.006) and 1.480-fold risk for high GS (95% CI: 1.090-2.009, P = 0.012) respectively. Interestingly, concomitant elevated level of Lp(a) and LDL-C conferred the highest risk for both presence [OR = 1.845, 95% CI: 1.339-2.541, P < 0.001] and severity [OR = 1.736, 95% CI: 1.188-2.538, P = 0.004] of CAD.

CONCLUSIONLipoprotein (a) is a useful marker for predicting the presence and severity of CAD, especially combined with LDL-C.
