To investigate the association of pancreatic steatosis with coronary atherosclerosis in patients with type 2 diabetes mellitus (T2DM). Patients with T2DM who underwent coronary computed tomography angiography(CCTA)in our center due to chest pain were enrolled from January 2016 to February 2019. According to the CCTA findings,patients were divided into normal group,mild-to-moderate coronary atherosclerosis group and severe coronary atherosclerosis group. CT attenuation of pancreas and spleen was measured on abdominal non-enhanced CT,and the CT attenuation indexes including the difference between pancreatic and splenic attenuation (P-S) and the ratio of pancreas-to-spleen attenuation (P/S) were calculated. Analysis of variance or Kruskal-Wallis rank test were used to assess differences among each group. Logistic regression analysis was used to analyze the risk factors of severe coronary stenosis. The accuracy of P/S in predicting severe coronary artery stenosis was assessed by receiver operator characteristic (ROC) curve analysis. A total of 173 consecutive T2DM patients were enrolled. These patients included 27 patients with normal coronary artery (15.6%),124 patients with mild to moderate stenosis (71.7%),and 22 patients with severe stenosis (12.7%). There were significant differences in CT attenuation of pancreas (=11.543,=0.003),P-S (=11.152,=0.004) and P/S (=11.327,=0.004) among normal coronary artery group,mild and moderate stenosis group,and severe stenosis group. The CT attenuation of pancreatic head,body,and tail significantly differed in patients with coronary artery stenosis (=14.737,=0.001). After adjusting for confounding factors,multiple Logistic regression showed that P/S (=0.062,95%=0.008-0.487,=0.008) was still significantly associated with the severe coronary artery stenosis. The area under the ROC curve of P/S for the diagnosis of severe coronary artery stenosis was 0.701,and the optimal cutoff point was 0.660. CT attenuation of pancreas and CT attenuation indexes are associated with the severity of coronary stenosis in T2DM patients,suggesting that pancreatic steatosis may be used as one of the indicators for predicting severe coronary artery stenosis.

To systematically evaluate the risks of cardiocerebral vascular events in patients with primary biliary cholangitis(PBC). Methods We carried out a Meta analysis by RevMan 5.3 software to investigate literatureon the risk of cardiocerebral vascular events in patients with PBC and controls. Results Compared with non-PBC controls,PBC patients had significantly higher risk of coronary events(=1.56,=0.0002);however,the risk of cerebrovascular events showed no significant difference between these two groups(=1.01,=0.94).Subgroup analysis demonstrated a significantly lower risk of transient ischemic attack or carotid stenosis in PBC patients(=0.63,=0.03);however,there was no significant difference in the risk of stroke(=1.11,=0.40). Conclusion Patients with PBC have an increased risk of coronary events but may have a lower risk of transient ischemic attack or carotid stenosis.

OBJECTIVE: To investigate the association of CXCL12 and CXCR4 polymorphisms with the genetic risk and severity of coronary stenosis in patients with coronary artery disease (CAD). METHODS: Competitive allele specific PCR(KASP) was performed to identify the genotypes of rs2297630 and rs2322864 polymorphisms in 302 CAD patients and 302 age-and gender-matched healthy controls. The severity of CAD patients was assessed by the Gensini scoring system according to the results of coronary arteriography. The association of rs2297630 and rs2322864 polymorphisms with genetic risk of CAD and Gensini scores were analyzed by unconditional logistic regression and multivariate linear regression respectively. RESULTS: There were significant differences in the genotype and allele frequencies of both rs2297630 and rs2322864 between the CAD group and healthy control (all <0.01). Regression analysis showed that rs2297630 polymorphism was associated with genetic risk of CAD and Gensini scores (all <0.01). People who carried the AA genotype suffered higher risk of CAD susceptibility and more serious coronary stenosis (all <0.01), compared with GG genotype carriers. There was also significant association between rs2322864 polymorphism and genetic risk of CAD (<0.01); those who carried the CT genotype had higher risk of CAD (<0.01), compared with TT genotype carriers. However, rs2322864 polymorphism was not associated with the severity of coronary stenosis (>0.05). CONCLUSIONS Gene polymorphism of CXCL12 rs2297630 is associated with the genetic risk of CAD and the severity of coronary stenosis. Moreover, the gene polymorphism of CXCR4 rs2322864 is associated with genetic risk of CAD, but not with the severity of coronary stenosis.

Coronary ostial stenosis after aortic valve replacement (AVR) is a rare but life-threatening complication. Here, we report a case of right coronary artery ostial stenosis in a patient who had a history of re-do AVR and normal preoperative coronary angiographic findings. The patient was successfully treated with a drug-eluting stent.

To analyze two common factors for perioperative ischemic stroke in patients with concomitant carotid and coronary artery severe stenosis and to improve the therapeutic effect.
 Methods: A total of 44 patients with multi-vessel coronary artery disease combined with carotid stenosis, who admitted to the Department of Cardiac Surgery, the First Affiliated Hospital of Xiamen University from 2008 to 2014, were enrolled in this study. Among them, 32 cases were male, 12 cases was female. All patients received coronary artery bypass grafting after treatment of neck diseases. The surgical outcomes and follow-up results were analyzed retrospectively.
 Results: One patient received carotid endarterectomy suffered hemiplegia, whose symptoms were improved after positive clinical treatment. One patient suffered transient ischemic attack, and 5 patients displayed the cerebrovascular syndromes a week later after surgery. Twelve patients suffered nerve function damage 48 hours later after surgery. Nine patients received intra-aortic ballon pump, 1 patient received thoracotomy hemostasis, 3 patients suffered sternal dehiscence; 27 patients showed atrial fibrillation. Two patients died after surgery. The follow-up duration ranged from 1-7 years and the follow-up rate was 90%. The ischemic symptoms were improved in 44 patients. Six patients complained the recurrence of angina, but no abnormalities were found in coronary angiography or computed tomography angiography. One patient died of malignant tumor during the follow-up duration.
 Conclusion: For patients with concomitant carotid and coronary artery severe stenosis, it is more likely to suffer ischemic cerebral stroke. However, carotid stenosis is not the only factor, other key factors relevant to ischemic cerebral stroke shouldn't be ignored either.

Conventional coronary angiography (CAG) has limitations in evaluating lesions producing ischemia. Three dimensional quantitative coronary angiography (3D-QCA) shows reconstructed images of CAG using computer based algorithm, the Cardio-op B system (Paieon Medical, Rosh Ha'ayin, Israel). The aim of this study was to evaluate whether 3D-QCA can reliably predict ischemia assessed by myocardial fractional flow reserve (FFR) < 0.80. 3D-QCA images were reconstructed from CAG which also were evaluated with FFR to assess ischemia. Minimal luminal diameter (MLD), percent diameter stenosis (%DS), minimal luminal area (MLA), and percent area stenosis (%AS) were obtained. The results of 3D-QCA and FFR were compared. A total of 266 patients was enrolled for the present study. FFR for all lesions ranged from 0.57 to 1.00 (0.85 +/- 0.09). Measurement of MLD, %DS, MLA, and %AS all were significantly correlated with FFR (r = 0.569, 0609, 0.569, 0.670, respectively, all P < 0.001). In lesions with MLA < 4.0 mm2, %AS of more than 65.5% had a 80% sensitivity and a 83% specificity to predict FFR < 0.80 (area under curve, AUC was 0.878). 3D-QCA can reliably predict coronary lesions producing ischemia and may be used to guide therapeutic approach for coronary artery disease.

INTRODUCTIONThis study aimed to examine the long-term clinical outcomes of coronary fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) in a real-world population in an Asian tertiary centre.

MATERIALS AND METHODSAll patients who underwent FFR measurement for intermediate coronary lesions in our centre from June 2002 to December 2009 were enrolled. A threshold of FFR ≤0.75 was used for revascularisation. All the patients were prospectively followed-up for major adverse cardiac events (MACE) of death, myocardial infarction (MI), target vessel revascularisation (TVR) and stent thrombosis.

RESULTSBased on FFR measurement, 368 (57%) patients were treated medically while 278 (43%) underwent revascularisation. At a mean follow-up duration of 29.7 ± 16 months, 53 (14.4%) patients in the medical therapy group and 32 (11.5%) patients in the revascularised group experienced MACE (P = 0.282). There were no statistical differences in all the clinical endpoints between the 2 groups.

CONCLUSIONMedical therapy based on FFR measurement is associated with low incidences of MACE at long-term follow-up.
