Histomorphological, ultrastructural as well as morphometrical age-related modifications of fundic place of recent Zealand bunnies (Oryctolagus cuniculus).
97; 95% CI, 0.96-0.98; P less then 0.001), and lower common carotid artery end-diastolic velocity (CCA-EDV) (OR, 0.97; 95% CI, 0.95-0.99; P = 0.005) were independently related to the presence of CAD. In patients without CAD, increased PWV was independently related to the presence of carotid plaque. In survival analysis, patients with isolated CAD had a higher probability of composite CV events; those with isolated carotid plaque had a higher probability of heart failure (HF) and mortality than their counterpart groups (P less then 0.05). Even in patients without carotid artery plaque, careful coronary evaluation is needed in older or male patients with smoking history, lower HDL-cholesterol level, or lower CCA-EDV. Carotid plaque may be a potential risk factor for HF.Patients with impaired kidney function have a high frequency of intraplaque hemorrhage (IPH) in their coronary arteries. Levels of cyclophilin A (CyPA), an indirect matrix metalloproteinase inducer, are increased in deceased patients who had impaired kidney function. In this study, we have examined the relationship between IPH and CyPA.We examined 47 samples of coronary plaque from 27 cadavers with coronary stenosis. These sections, all with > 50% coronary stenosis, were stained with an antibody against CyPA and the expression of CyPA was semi-quantified. Cadavers and plaques were classified into one of two groups depending on the presence or absence of IPH. IPH was defined as the presence of red blood cells stained with hematoxylin and eosin (HE) indicative of overt acute hemorrhage.In an individual analysis, estimation of glomerular filtration rate (eGFR) in the IPH group was significantly lower than that in the non-IPH group (P = 0.002). In a histological analysis, the percentage of stained area of CyPA in the IPH group was significantly higher than that in the non-IPH group (P less then 0.0001).IPH was associated with a significantly higher expression of CyPA in this study. In addition, patients with IPH in their coronary arteries had significantly impaired kidney function.Acute pericarditis is inflammation of the pericardium with or without pericardial effusion. In the pediatric population, most patients with acute pericarditis are diagnosed with idiopathic pericarditis. Herein, we present two children with idiopathic pericarditis who underwent immunological assessment of pericardial effusion for the first time. Both patients showed equally high levels of interleukin-6 in the pericardial effusion. However, they had different treatment responses, in accordance with the pericardial effusion and serum interleukin-10 concentrations. Our present cases suggest that interleukin-10 may be associated with the response to anti-inflammatory therapy in idiopathic acute pericarditis.The risk of thromboembolic events is significantly increased among patients with heart failure, even in those without atrial fibrillation. However, it is still unclear whether patients with heart failure and sinus rhythm can benefit from prophylactic anticoagulant therapy.This was a retrospective review of the pathophysiological mechanisms, epidemiological studies, and clinical trials on anticoagulation in patients with heart failure and sinus rhythm.Some subgroup analyses of clinical trials found that prophylactic anticoagulant therapy could reduce the incidence of stroke in patients with heart failure and sinus rhythm, and the risk of bleeding was significantly increased. Regarding the incidence of primary endpoint outcomes, all results from clinical trials were negative.Prophylactic anticoagulation did not improve the clinical outcome in patients with heart failure and sinus rhythm.Periprocedural myocardial infarction (PMI) is closely associated with long-term cardiovascular events. The factors associated with PMI are not fully understood. The purpose of this study was to investigate the determinants of PMI in contemporary elective percutaneous coronary intervention (PCI). Overall, 731 elective PCI was divided into the PMI (n = 27) and non-PMI (n = 704) groups. Univariate and multivariate logistic regression analysis was used to find factors associated with PMI. In the univariate analysis, PMI was associated with complex lesion characteristics, such as the lesion length, lesion angle, calcification, and Medina classification. In the multivariate logistic regression analysis, the lesion length (per 10-mm increase odds ratio (OR), 1.477; 95% confidence interval (CI), 1.161‒1.879; P = 0.002), lesion angle ≥ 45° (versus lesion angle less then 45° OR, 4.244; 95% CI, 1.187‒15.171; P = 0.026), and Medina classification (0,1,1) / (1,1,1) (versus other lesions OR, 14.843; 95% CI, 6.235‒35.334; P less then 0.001) were significantly associated with PMI. Of the 24 lesions with lesion angle ≥ 45° in the PMI group, 14 had final TIMI flow grade ≤ 2 in side branches and 9 had transient slow flow in main branches/transient ST elevation during PCI. Of the 87 lesions with Medina classification (1,1,1) / (0,1,1), 19 had final TIMI grade ≤ 2 in side branches. In conclusion, the lesion length, lesion angle ≥ 45°, and Medina classification (0,1,1) / (1,1,1) were significantly associated with PMI in contemporary elective PCI. Preventing flow limitation in both side branches and main vessels in elective PCI for the diffuse long, angulated, or true bifurcation lesions is important.Recurrence of atrial tachyarrhythmias (ATA) following catheter ablation for atrial fibrillation (AF) is often associated with the recovery of conduction into previously isolated pulmonary veins (PVs). Little evidence concerning repeat PV isolation (PVI) and non-PV ATA ablation has been reported. This study aimed to explore the clinical outcome of recurrent ATA ablation after PVI and the difference between patients with and without non-PV ATA.A total of 49 patients without structural heart diseases who received catheter ablation for recurrent AF between January 2014 and December 2018 were recruited (prior ablation with PVI only 71.4% and PVI with cavotricuspid isthmus line ablation 28.6%). Patients were divided into two groups according to the presence or absence of non-PV ATA.Most patients (53.1%) experienced very late recurrence with a median duration of 15 months. read more A total of 15 patients had non-PV ATA and received non-PV ATA ablation whereas 34 patients received only repeat PVI for reconnected PVs. A higher pulmonary arterial systolic pressure (PASP) was associated with non-PV ATA (odds ratio 1.161; 95% confidence interval 1.021-1.321; P = 0.023). During 4.7 ± 1 months, 4/15 (26.7%) and 1/34 (2.9%) patients with and without non-PV ATA, respectively, had ATA recurrence (P = 0.011). The cumulative incidence of ATA recurrence after repeat ablation was significantly lower in patients without non-PV ATA (P = 0.013).In our study, a high PASP was associated with non-PV ATA in patients with recurrent AF. Repeat PVI had a high rate of maintenance of sinus rhythm in patients without non-PV ATA.Transcatheter closure (TCC) has emerged as the first-line treatment for coronary artery fistulas. However, limited data exist regarding the long-term outcomes and technical aspects of this procedure. We aimed to report the long-term outcomes and technical aspects of TCC of large coronary-cameral fistulas (CCFs).All patients with large CCFs who underwent attempted TCC using the patent ductus arteriosus (PDA) occluder or Amplatzer vascular plug (AVP), from June 2002 to December 2017, were retrospectively reviewed. A total of 23 patients with large CCFs underwent attempted TCC using the PDA occluder or AVP. Most CCFs originated from the right coronary artery and drained predominantly into the right heart chamber. Procedural success was achieved in 21 (91.3%) patients. Devices were deployed using the arteriovenous loop in 15, transarterial approach in 4, and arterio-artery loop approach in 2 patients. Procedural complications included coronary spasm in one and side branch occlusion in one patient. Among these 21 patients with successful device implantation, follow-up angiograms or computed tomography angiograms were obtained in 14 (66.7%) patients at a median of 11.0 (range, 9.8-16.3) months. Late complications included thrombosis of residual fistula segment without myocardial infarction (MI) in one, coronary thrombosis resulting in MI in one, and recanalization necessitating re-intervention in one patient. No death and device embolization occurred.TCC of large CCFs using the PDA occluder or AVP is an effective therapy in anatomically suitable candidates, with favorable long-term outcomes. Given that potentially hazardous complications may occur late after the procedure, long-term periodic evaluation is mandatory.This study aims to compare and analyze the health-related quality of life (HRQoL) of adult patients with ventricular septal defects (VSDs) who underwent transthoracic or transcatheter device closure.The HRQoL data of 30 patients who underwent transthoracic device closure for VSDs and 30 who underwent transcatheter device closure for VSDs were retrospectively evaluated before and one year after the procedure. The Medical Outcomes Study 36-Item Short-Form (SF-36), the Hospital Anxiety and Depression Scale (HADS), and a self-designed questionnaire were used as evaluation tools.After treatment, both groups showed significant improvements in SF-36 and HADS scores. After comparing the two groups regarding the SF-36, there was a significant difference in the two dimensions of vitality and mental health. There were no statistically significant differences in the HADS-A and HADS-D scores between these two groups. The results of the self-designed questionnaire also showed that the subjective feedback of the two groups was roughly the same. In the process of exploring the influential factors, we found that the scores of patients on most dimensions of the SF-36 in the two groups showed a significantly negative trend with increasing age. In terms of HADS scores, patients in both groups showed a tendency toward increasing scores with age.The HRQoL of adult patients undergoing transthoracic and transcatheter device closure for VSDs was similar, and the HRQoL was affected by the patient's own condition, so it is necessary to pay more attention to patients after device closure.Dickkopp-3 (DKK3) has been identified to play a protection role against atherosclerosis. However, little is known about the relationship between serum DKK3 levels and subclinical coronary atherosclerosis. We aimed to investigate the association of serum DKK3 with coronary stenosis in an asymptomatic Chinese population. A total of 550 Chinese adults aged 40-60 years and without symptoms or histories of cardiovascular diseases were randomly selected to undergo coronary computed tomography angiography. We defined ≥ 50% luminal narrowing as significant coronary stenosis and measured serum DKK3 levels by an enzyme-linked immunosorbent assay (ELISA). Fifty-nine participants had significant coronary stenosis and 223 had less then 50% coronary stenosis. Proportions of significant coronary stenosis were 13.7%, 11.4%, and 7.1% in DKK3 tertiles 1-3, respectively (Ptrend = 0.0427). In the univariable multinomial logistic regression model, a decreasing DKK3 tertile was associated with significant coronary stenosis with borderline significance (OR 1.
