Background - Vein of Marshall (VOM) ethanol infusion is a relatively new therapeutic option for atrial tachyarrhythmias. We aimed to evaluate the feasibility, pitfalls, and complications associated with this procedure in a large cohort of patients. Methods - Successful ethanol infusion, VOM-related lesion extent, and serious complications were evaluated in 713 consecutive patients treated with VOM ethanol infusion. Results - While feasible in 88.9% of cases, VOM ethanol infusion failure mainly resulted from non-identification (6.2%), non-cannulation (1.5%), or ethanol infusion in the wrong vein (1.7%). The Vieussens valve was a helpful landmark and was visible in 63.2% of cases. Multivariable analysis identified previous coronary sinus ablation as the only predictor for non-identification. The mean area of VOM-related endocardial scarring was 10.2±5.3 cm 2 . VOM dissection (10.7%), iodine leakage (3.0%), and VOM morphology without visible branches (3.0%) were associated with smaller VOM-related scarring (5.0±3.9 cm 2 , 6.6±3.5 cm 2 and 4.7±2.3 cm 2 , with a p <0.0001, p <0.044, and p <0.0001, respectively). Ethanol infusion in a wrong vein was associated with less mitral line block (72.7% vs. 95.8%, p=0.012). A total of 14 serious complications (2.0%) occurred: 7 tamponades, of which were 6 delayed and treated with pericardiocentesis (2 of these patients had per-procedural VOM perforation), 4 strokes, 1 anaphylactic shock, 1 atrioventricular block, and 1 left appendage isolation. Only 4 of these complications occurred during the procedure. Conclusions - Although limited by previous coronary sinus ablation, VOM ethanol infusion is a highly feasible treatment for atrial tachyarrhythmia, with a low rate of serious complications.

PURPOSE: To verify if the methylene blue (MB) administration prevents and/or reverses the compound 48/80 (C48/80)-induced anaphylactic shock in pigs. METHODS: Female Dalland pigs were anesthetized and had the hemodynamic parameters recorded during the necessary time to administer some drugs and observe their effect. The animals were randomly assigned to one of the five groups: 1) control; 2) MB: the animals received a bolus injection of MB (2 mg/kg) followed by continuous infusion of MB (2.66 mg/Kg/h delivered by syringe infusion pump); 3) C48/80: the animals received a bolus injection of C48/80 (4 mg/kg); 4) C48/80+MB: the animals received a bolus injection of C48/80 (4 mg/kg) and 10 minutes after the C48/80 administration the animals received a bolus injection of MB (2 mg/kg) followed by continuous infusion of MB (2.66 mg/Kg/h delivered by syringe infusion pump); 5) MB+C48/80: the animals received a bolus injection of MB (2 mg/kg) and 3 minutes later they received a bolus injection of C48/80 (4 mg/kg). RESULTS: The intravenous infusion of MB alone caused no changes in the mean arterial pressure (MAP) showing that the administered MB dose was safe in this experimental model. The C48/80 was effective in producing experimental anaphylactic shock since it was observed a decrease in both MAP and cardiac output (CO) after its administration. The MB did not prevent or reverse the C48/80-induced anaphylactic shock in this model. In fact, the MAP of the animals with anaphylactic shock treated with MB decreased even more than the MAP of the animals from the C48/80 group. On the other hand, the C48/80-induced epidermal alterations disappeared after the MB infusion. CONCLUSION: Despite our data, the clinical manifestations improvement brings some optimism and does not allow excluding the MB as a possible therapeutic option in the anaphylactic shock.

Background: Elderly people with uncontrolled diabetes mellitus (DM) are at risk of falls, which can lead to injury and disability. Not much is known of informal caregivers’ awareness of falls in elderly patients with DM. Objective: This study aims to identify an association between caregiver’s awareness and falls in elderly patients with DM. Methods: A total of 136 pairs of DM patients and their respective family caregivers were recruited from a clinical service center at Chiang Mai University, Thailand. The questionnaire regarding the caregiver’s awareness of the risk of falls in elderly patients was given via a face-to-face interview. Each elderly patient was asked about their history of falls in the prior year, and the risk of falls was assessed by Time Up & Go (TUG) test. Logistic regression analysis was performed to determine association. Results: The mean age of the DM patients was 65.7 years. Sixty-two patients (45.6%) had fallen at least once in the prior year. The mean TUG test result was 12.67±1.83 second. Most caregivers demonstrated a high level of awareness regarding the risk of falls in elderly patients. The results of the multivariable analysis showed that three variables – balance problems, risk of falls assessed by TUG test, and scores of caregiver’s awareness of risk of falls – were significantly related to falls in the previous year among elderly patients with DM (p-value<0.05). Conclusion: The caregivers’ awareness of fall risk may influence fall occurrence among older adults with DM. An intervention program to improve awareness among informal caregivers should be considered for fall prevention in elderly people.

Background:Hydroxychloroquine (HCQ) is an essential drug for systemic lupus erythematosus. But in Japan, chloroquine and HCQ remain unavailable until mid 2015 because of a series of lawsuits about its retinal toxicity in the 1970s. There is insufficient knowledge regarding renal protective effect of HCQ.Objectives:We aimed to investigate its efficacy of adding HCQ for Lupus nephritis (LN) as a maintenance-phase therapy.Methods:We conducted an observational retrospective cohort study included patients with LN (n=42) in maintenance-phase in Japan. We reviewed medical records of LN patients aged > 18 years who were initiated HCQ from May 2015 to May 2018. Maintenance phase was defined as stabilization in serum creatinine and urinary segment after induction therapy and who achieved complete or partial remission. The annual change of proteinuria was compared between patients on HCQ who have proteinuria (>0.5g/gCr) or not. Other outcome measures were disease flare, dose of steroids, renal and immunologic features.Results:A total of 42 patients were analyzed and allocated to two groups based on their amount of daily urine protein level: HCQ with proteinuria as group A (>0.5g/gCr, n=14) and HCQ without proteinuria as group B(≦0.5g/gCr, n=28). Both groups were comparable, with mean (SD) age of 36.1 (12.9) years and 37.5 (13.8), female 78.6% and 92.9% in each group, mean (SD) disease duration until HCQ of 3.5 (3.25) and 3.3 (2.9) years in group A and group B, with prednisolone dose at base line of 10.3 (7.1) mg and 7.9 (4.4) mg, respectively. The mean (SD) proteinuria at base line was 1.38 (1.11) g/gCr in group A and 0.20 (0.09) g/gCr in group B and after 12 months, proteinuria decreased in group A (-1.34 g/gCr in group A vs +0.03 g/gCr in group B; p<.001;95% CI,0.305-0.736). No relapse was experienced in group A during the study period.Conclusion:In patients with clinically stable LN but with proteinuria, hydroxychloroquine is a good therapeutic option for achievement of complete remission.Disclosure of Interests:None declared

Abstract Background Coronary sinus Reducer device (CSF) implantation is a novel therapeutic option to relieve symptoms in patients with refractory angina (RA). There is limited real-world data describing its use outside of clinical trials. Aim To assess the safety and efficacy of this procedure in a real-world setting. Methods This is a report of a single centre prospective registry of consecutive patients with RA (CCS II-IV) deemed unsuitable for revascularization. Between May 2017 and August 2019, 17 patients were referred to CSF implantation. Baseline and follow-up evaluation consisted of clinical assessment, including completion of the short version of the Seattle Angina Questionnaire (SAQ-7) and CCS class evaluation and objective evaluation by transthoracic echocardiography and cardiopulmonary exercise test (CPET). Results A total of 13 patients (70,6±6,5 years, 76,9% male) underwent CSF implantation with a procedural success of 84.6%. No cases of periprocedural serious adverse events were reported. At 12-month follow-up, any reduction in CCS Class was achieved in 72.7% of cases, with 27.2% reducing 2 CCS classes. Baseline CCS score was reduced from 2.8±0.4 to 1.7±0.8 (p=0.009). Quality of life (QoL) was significantly improved as assessed by the improvement seen in all items of SAQ-7 (p&lt;0.017 for all). CPET duration was significantly increased (p=0.034), but no change was noted in the remainder CPET variables. During follow-up, 3 patients suffered myocardial infarction, resulting in 1 death. Conclusion CSF implantation in patients with RA was safe and led to a significant reduction of the angina burden and improvement of QoL at 12-month follow-up.

Statin Use

Background: Management of lipids is vital in patients with underlying coronary artery disease (CAD). According to the American College of Cardiology (ACC) guidelines, all patients with CAD should have low density lipoproteins (LDL) goals to be less than 100 mg/dl with the therapeutic option of treatment to less than 70 mg/dl. This can be achieved using multiple lipid lowering agents, however statin use is encouraged in CAD patients due to its multiple beneficial effects. Methods: We conducted a retrospective cohort study focusing on lipid management and statin use in 857 veterans undergoing percutaneous coronary intervention (PCI) between September 2004 and December 2009 at the Jesse Brown Veterans Hospital in Chicago, IL. Values were collected both pre-intervention as well as at six month follow up. Results: Both pre and post PCI, focus was maintained on the total cholesterol as well as the LDL levels. The mean total cholesterol prior to intervention was 166mg/dl and decreased to150mg/dl at six month follow up. The LDL mean pre-PCI was 98mg/dl and at six months the mean LDL decreased to 86mg/dl. With regards to ACC guidelines, the percent at goal for LDL less than 100mg/dl increased from 59% pre-PCI to 74% post-PCI Furthermore, treatment to less than 70mg/dl increased from 22 to 32% at six months. Lastly, the use of statins increased from 72 to 89%. Conclusions: There were in improvements in both total cholesterol and LDL values at six months post-PCI. There were also improvements in the percentage of patients who met the ACC recommended goal of LDL cholesterol less than 100mg/dl and the suggested goal of 70mg/dl. At six months, there was also an increase in usage of statin therapy.

Intracardiac Pressure

Introduction: B-type natriuretic peptide (BNP) is widely used as a biomarker of heart failure and typically rises in response to increased intracardiac pressure. BNP levels have been measured in patients with coronavirus disease 2019 (COVID-19) to assess the cardiovascular contribution to respiratory failure and guide diuresis. Whether BNP levels do predict the need for mechanical ventilation (MV) is however unknown. Methods: The Michigan Medicine Covid-19 Cohort (M 2 C 2 ) is an ongoing prospective observational study in which detailed clinical, laboratory and outcomes data were collected from chart review of consecutive adult patients hospitalized for COVID-19. Patients who were positive for SARS-CoV-2 infection but without symptoms of COVID-19 were not included in this cohort. We identified 495 patients admitted between March 1 st and May 1 st for COVID-19, of whom 290 (58.6%) had BNP levels measured during their hospitalization. We examined the association between BNP and the need for MV during their hospitalization. Results: Among the 290 patients evaluated, the mean age was 62 (SD 15), 169 (58.3%) were male, 135 (46.6%) were blacks, and 61 (21.0%) had pre-existing heart failure. The median BNP level was 50 pg/ml, and 104 (35.9%) of patients had a BNP level > 100 pg/ml. A total of 130 (44.8%) required MV during their hospitalization. The median BNP level in patients who required MV was 63 pg/ml (IQR 25-171), compared to 46 pg /ml (IQR 17-187) in patients who did not, P=0.23. In multivariable analysis adjusting for age, gender, race, pre-existing heart failure, and serum creatinine on admission, BNP>100 pg/ml was not associated with the need for MV. Conclusions: In patients hospitalized for COVID-19, BNP levels were not associated with the need for MV, suggesting that the cardiovascular contribution to respiratory failure in these patients is likely minor compared to the inflammatory response or direct impact of the virus.

Sinus Node Disease

The association of sinus node disease and atrial tachyarrhythmias characterizes the bradycardia–tachycardia syndrome, which may result in an increased risk of heart failure, stroke, and death. Ageing and several cardiac and extracardiac diseases, which have the potential to affect both the atrial and the ventricular myocardium, can manifest their influence predominantly on the atria, leading to an atrial cardiomyopathy. In these cases, the same pathological process which leads to sinus node dysfunction can create a favourable substrate also for atrial tachyarrhythmias, which, if not present at the time of the initial diagnosis of the sinus node disease, can occur with an increasing prevalence during follow-up. In younger patients with no evident structural heart disease, a bradycardia–tachycardia syndrome may be the first clinical and unexpected manifestation of a still undiagnosed inherited genetic disease and therefore a specific diagnostic workup is necessary. In bradycardia–tachycardia syndrome, the most frequently encountered atrial tachyarrhythmia is atrial fibrillation, while typical atrial flutter is rarer. In peculiar subgroups of patients, other atrial tachyarrhythmias, such as atypical atrial flutter, macroreentrant or focal atrial tachycardia, may be present. In bradycardia–tachycardia syndrome, the evolution of atrial tachyarrhythmias clearly shows a worsening with an prevalence of associated atrial tachyarrhythmia over time. Pharmacological therapy for arrhythmias is of limited use, due to the concomitant sinus node dysfunction. The modality of pacing used to manage the sinus node disease has to be carefully chosen to minimize the evolution of atrial tachyarrhythmias. In fact, while ventricular pacing increases the incidence of atrial fibrillation and stroke, dual-chamber pacing with a specific algorithm for ventricular pacing minimization and prevention and treatment of atrial tachyarrhythmias reduces a composite endpoint of evolution to permanent atrial fibrillation, hospitalization, and death.
