    Background: It has been demonstrated that diabetic dyslipidaemia is the chief bridge between diabetes and incremental risk of cardiovascular disease in patients with diabetes. However, the characteristics of lipoprotein subfractions distribution in patients with type 2 diabetes (T2D) have not been fully investigated. The aim of present study was to evaluate the distributions of lipoprotein subfractions in T2D patients. Methods: A total of 920 patients, who have not received lipid-lowering drug treatment previously, were consecutively enrolled in this study. Based on the evidence of diabetes, patients were divided into T2D group (n=204) and non-T2D group (n=716). Both low- and high-density lipoprotein cholesterol (LDL- and HDL-C) subfractions were analysed using the Quantimetrix Lipoprint System. The distributions of lipoprotein subfractions were evaluated in patients with and without T2D. Results: Compared with non-T2D individuals, the T2D group manifested significantly lower large HDL-C concentration/HDL subfraction percentage, smaller mean LDL particle size but higher small HDL-C and LDL-C concentrations as well as small HDL and LDL subfraction percentages. Moreover, the data indicated that the small HDL-C/ LDL-C concentrations, the small and large HDL subfraction percentages along with the mean LDL particle size were independently related to the existence of T2D (95% CI=1.009-1.067, p=0.009; 95% CI=0.938-0.983, p=0.001; 95% CI=1.023-1.135, p=0.005; 95% CI= 1.005-1.048, p=0.014; 95% CI=0.940-0.999, p=0.040; respectively) assessed by logistic regression analysis. Conclusions: The present study indicated that the changes of lipid profile in patients with T2D are characterised by abnormal distributions of lipoprotein subfractions apart from clinically atherogenic dyslipidaemia.

    Background: Shallow lesions could be the predominant factor affecting the efficacy of ventricular radiofrequency (RF) ablations. The objective of this study was to assess lesion dimensions and overheating in extended RF ablations up to 180seconds and compare with that of conventional 30seconds ablations. Methods: The Navistar Thermocool irrigated catheter (Biosense Webster, CA, USA) was used in a previously validated myocardial phantom. Ablations were performed with 20W, 30W, 40W and 50W powers for 180seconds. The volume of lesion and overheating were measured at 53 0 C and 80 0 C isotherms respectively. Results: A total of 110 RF lesions were analysed. The lesion depth increment when ablation was extended from the conventional 30seconds to 90seconds were 31.2+/-0.2, 33.6+/-0.6, 36.3+/-1.8% of that at 30seconds, respectively for powers 30W, 40W and 50W. During 30W ablations, at 90seconds the lesion width and depth were 95.4+/-1.2%, 91.8+/-1.6% respectively of the final dimensions at 180seconds. Similar proportions were observed for 40W and 50W. During 40W ablations, the volume of overheating was 113+/-6% and 184+/-11% higher at 90seconds and 180seconds respectively compared to that at 30seconds and was 142+/-9% and 194+/-9% for 50W ablations. Conclusion: Extending RF ablations up to 90seconds significantly increased the lesion depth (30-40%), however, overheating was present at 40W and 50W powers. Ablations beyond 90seconds provided little incremental value.

    초록

    Background: The significance of worsening renal function (WRF) in patients admitted for acute decompensated heart failure (ADHF) is still controversial. We hypothesised that changes in brain natriuretic peptide (BNP) might identify patients with optimal diuretic responsiveness resulting in transient WRF, not negatively affecting the prognosis. Our aim was to verify if in-hospital trends of BNP might be helpful in the stratification of patients with WRF after treatment for ADHF. Methods: 122 consecutive patients admitted for ADHF were enrolled. Brain natriuretic peptide and eGFR were evaluated at admission and discharge. A 20% relative decrease in eGFR defined WRF, whereas a BNP reduction ≥40% was considered significant. The primary combined endpoint was death/urgent heart transplantation and re-hospitalisation for ADHF. Results: Worsening renal function occurred in 23% of patients without differences in outcome between patients with and without WRF (43% vs. 45%, p=0.597). A significant reduction in BNP levels over the hospitalisation occurred in 59% of the overall population and in 71% of patients with WRF. At a median follow-up of 13.0 (IQR 6-36) months, WRF patients with ≥40% BNP reduction had a lower rate of death/urgent heart transplantation/re-hospitalisation compared to WRF patients without BNP reduction (30% and 75%, respectively; p=0.007). Favourable BNP trend was the strongest variable in predicting the outcome in WRF patients (HR 0.222, 95% CI 0.066-0.753, p=0.016). Conclusions: Worsening renal function does not affect the prognosis of ADHF and, when associated with a significant BNP reduction, identifies patients with adequate decongestion at discharge and favourable outcome.

    초록

    Background: The New Zealand Cardiac Implanted Device Registry (Device) has recently been developed under the auspices of the New Zealand Branch of the Cardiac Society of Australia and New Zealand. This study describes the initial Device registry cohort of patients receiving a new pacemaker, their indications for pacing and their perioperative complications. Methods: The Device Registry was used to audit patients receiving a first pacemaker between 1 st January 2014 and 1 st June 2015. Results: We examined 1611 patients undergoing first pacemaker implantation. Patients were predominantly male (59%), and had a median age of 70 years. The most common symptom for pacemaker implantation was syncope (39%), followed by dizziness (30%) and dyspnoea (12%). The most common aetiology for a pacemaker was a conduction tissue disorder (35%), followed by sinus node dysfunction (22%). Atrioventricular (AV) block was the most common ECG abnormality, present in 44%. Dual chamber pacemakers were most common (62%), followed by single chamber ventricular pacemakers (34%), and cardiac resynchronisation therapy - pacemakers (CRT-P) (2%). Complications within 24hours of the implant procedure were reported in 64 patients (3.9%), none of which were fatal. The most common complication was the need for reoperation to manipulate a lead, occurring in 23 patients (1.4%). Conclusion: This is the first description of data entered into the Device registry. Patients receiving a pacemaker were younger than in European registries, and there was a low use of CRT-P devices compared to international rates. Complications rates were low and compare favourably to available international data.

  8. [해외논문]   Lead Extraction for Treatment of Cardiac Device Infection: A 20-Year Single Centre Experience  

    Gomes, S. ; Cranney, G. ; Bennett, M. ; Giles, R.
    Heart, lung & circulation v.26 no.3 ,pp. 240 - 245 , 2017 , 1443-9506 ,

    초록

    Background: Infection is one of the most feared complications of cardiac implantable electronic devices. We report microbiology, antimicrobial therapy and infection recurrence in patients with cardiac device infection (CDI) treated with transvenous lead extraction (TLE) at a single centre over a 20-year period. Methods: We identified a cohort of consecutive patients undergoing TLE for CDI by a single operator at a single high volume centre. Retrospective analysis of patient characteristics, microbiology, outcomes and infection recurrence was performed. Results: Between May 1992 to March 2012, 348 patients underwent extraction due to localised or systemic infection. Seven hundred and twenty leads were extracted from these patients. The mean follow-up was 5.5+/-4.9 years. Staphylococcal species accounted for 81% of CDI. A difference is seen in infection onset for device revision compared with initial implants [median 10 months vs 24 months, P=0.0001]. Duration of antibiotics therapy depended on the nature of the CDI (21 days post TLE for systemic vs. 10 days for localised infection, P

  9. [해외논문]   Multidisciplinary Assessment in Optimising Results of Percutaneous Patent Foramen Ovale Closure  

    Davies, A. ; Ekmejian, A. ; Collins, N. ; Bhagwandeen, R.
    Heart, lung & circulation v.26 no.3 ,pp. 246 - 250 , 2017 , 1443-9506 ,

    초록

    Background: Percutaneous patent foramen ovale (PFO) closure is a therapeutic option to prevent recurrent cerebral ischaemia in patients with cryptogenic stroke and transient cerebral ischaemia (TIA). The apparent lack of benefit seen in previous randomised trials has, in part, reflected inclusion of patients with alternate mechanisms of stroke. The role of formal neurology involvement in accurately delineating the likely aetiology of stroke or TIA is crucial in appropriate identification of patients for device closure. Furthermore, as the benefits of device closure may accrue over time, long-term follow-up is essential to define the role of device closure in management of presumed cryptogenic stroke. Methods: We retrospectively reviewed our experience with percutaneous PFO device closure since 2005. All subjects who underwent PFO closure at John Hunter and Lake Macquarie Private Hospitals were included in the study. All patients referred for device closure following cryptogenic stroke or TIA had first undergone formal neurology review with appropriate imaging and exclusion of paroxysmal atrial arrhythmia. Patients with a history of transient ischaemic attack (TIA) are frequently referred to a specialised clinic, aimed to identify patients with conditions not referable to cerebral ischaemia, with investigations initiated by the specialist clinic to elucidate an underlying aetiology. Outcome data was derived from the Hunter New England Area Local Health District Cardiac and Stroke Outcomes Unit, in addition to review of the medical record. The Cardiac and Stroke Outcomes Unit prospectively identified all patients presenting with stroke, TIA and atrial fibrillation. Results: One hundred and twelve consecutive patients undergoing percutaneous patent foramen ovale closure between 2005 and 2015 were identified. The average age was 42.7 years and 57 (50.9%) patients were male. Cryptogenic stroke (68.8%) and transient cerebral ischaemia (23.2%) were the most common indications for PFO closure, with the Amplatzer device used in 83 cases (74.1%). Early residual shunting was visible in seven patients (6.3%), however on follow-up agitated saline study only two patients had residual shunt (1.8%). The annual risk of recurrent stroke or TIA was 0.21%. Conclusions: Percutaneous patent foramen ovale closure can be performed safely and effectively in patients with paradoxical embolism. In selected patients, following appropriate multidisciplinary specialist pre-procedural assessment, excellent long-term results with low incidence of recurrent events may be achieved.

    Heart, lung & circulation v.26 no.3 ,pp. 251 - 257 , 2017 , 1443-9506 ,

    초록

    Background: Obesity has been found to be a predictor of left ventricular hypertrophy (LVH). However, studies which divide obesity into metabolically healthy obesity (MHO) and metabolically unhealthy obesity (MUO) to study the effect of obesity on LVH have been rare. The present study aims to make clear the effects of various obese phenotypes and metabolic abnormalities on LVH. Methods: A total of 10,804 participants were involved in this cross-sectional study. ''Obesity'' and ''metabolically healthy'' were defined as BMI ≥ 25kg/m 2 and having none of the metabolic factors respectively. Results: It was found that metabolically unhealthy non-obesity (MUNO) (OR, 2.675; 95%CI, 1.603-4.462, P
