New insights into cirrhotic cardiomyopathy
No full textCirrhotic cardiomyopathy designates a cardiac dysfunction, which includes reduced cardiac contractility with systolic and diastolic dysfunction, and presence of electrophysiological abnormalities in particular prolongation of the QT interval. Several pathophysiological mechanisms including reduced beta-receptor function seem involved in the autonomic and cardiac dysfunction. Cirrhotic cardiomyopathy can be revealed by tissue Doppler imaging but is best demasked by physical or pharmacological stress. Liver transplantation may revert cardiac dysfunction but surgery and shunt insertion may also aggravate the condition. Moreover, cirrhotic cardiomyopathy may contribute to heart failure after invasive procedures and to development of hepatic nephropathy as part of a cardiorenal syndrome. Whether beta-blockers have a deleterious effect in this clinical situation remains to be settledCirrhotic cardiomyopathy designates a cardiac dysfunction, which includes reduced cardiac contractility with systolic and diastolic dysfunction, and presence of electrophysiological abnormalities in particular prolongation of the QT interval.

Experiences from COVID-19-driven use of telephone consultations in a cardiology clinic—The CoviTel study
No full textINTRODUCTION: The COVID-19 pandemic triggered a rapid shift towards telephone consultations (TC) in the out-patient clinic setting with little knowledge of the consequences. The aims of this study were to evaluate patient-centred experiences with TC, to describe patterns in clinical outcomes from TC and to pinpoint benefits and drawbacks associated with this type of consultations. METHODS: This mixed methods study combined an analysis of quantitative and qualitative data. A quantitative, retrospective observational study was conducted employing data from all 248 patients who received TC at an out-patient cardiology clinic during April 2020 with a one-month follow-up. Semi-structured interviews were conducted; Ten eligible patients were recruited from the outpatient clinic by purposive sampling. RESULTS: Within the follow-up period, no patients died or were acutely hospitalised. Approximately one in every four patients was transferred to their general practitioner, while the remaining three-quarter of the patients had a new examination or a new consultation planned. The cardiologist failed to establish contact with more than a fifth of the patients, often due to missing phone numbers. Ten patients were interviewed. Five themes emerged from the interviews: 1) Knowing an estimated time of the consultation is essential for patient satisfaction, 2) TC are well perceived when individually adapted, 3) TC can be a barrier to patient questions, 4) Video consultations should only be offered to patients who request it, and 5) Prescriptions or instructions made via TC do not cause uncertainty in patients. CONCLUSIONS: The TC program was overall safe and the patients felt comfortable. Crucial issues include precise time planning, the patient’s availability on the phone and a correct phone number. Patients stressed that TC are unsuitable when addressing sensitive topics. A proposed visitation tool is presented
Complete paroxysmal atrioventricular block in a 2-year-old girl
No full textWe present a case of atypical syncope in a 2-year-old, otherwise healthy girl. The patient presented with three episodes of syncope without any precipitating factors and no family history of sudden unexpected death. Holter monitoring revealed 24 events of complete atrioventricular block lasting up to 6 seconds. A normal 12-lead electrocardiogram does not necessarily exclude cardiac disease, and Holter monitoring is warranted in children with atypical syncope
Clinical outcomes of a short-Term familyfocused intervention for patients with atrial fibrillation-A randomised clinical trial
No full textAims To evaluate a family-focused intervention for patients with atrial fibrillation (AF) in addition to conventional care and to establish its effect on health-related quality of life (HRQoL), anxiety, depression, AF symptoms, and family support. Background AF is a widespread heart disease affecting the well-being of patients and their family members physically and psychologically. Supporting patients and their family members could potentially facilitate regaining family strength and improve HRQoL. Methods Patients with newly diagnosed AF were randomised to standard care or additional familyfocused intervention with change in global score of the Atrial Fibrillation Quality of Life Questionnaire (AFEQT) as primary outcome after six months' follow-up. Secondary outcomes included the Hospital Anxiety and Depression Score, the European Heart Rhythm Association score, the Ice Expressive Family Functioning Questionnaire, and the Ice Family-Perceived Support Questionnaire (ICE-FPSQ). Results Sixty-eight patients received standard care (n = 35) or family focused intervention (n = 33). The median change at the six-month follow-up on the global AFEQT score was 4.17 (-1.46-9.17) in the control group and 5.83 (-2.5-30) in the intervention group, yielding a median difference of-1.67 (p = 0.500). Change in ICE-FPSQ showed significant positive scores in favour of intervention (p < 0.001); other secondary outcome changes were non-significant. Conclusion The family-focused intervention had a small positive but non-significant effect on HRQoL compared to standard care. To address the impact of AF on the patients and family members seems to improve anxiety and depression scores and perceived family support.</p
Percutaneous atrial appendage occlusion for stroke prevention in patients with atrial fibrillation:a systematic review
No full textThis review aims to evaluate systematically the safety and efficacy of percutaneous left atrial appendage occlusion (PLAAO) in stroke prevention for patients with atrial fibrillation (AF). A systematic review of peer-reviewed journals on PLAAO before June 2011 was performed on three electronic databases. Fourteen studies were identified for evaluation. Overall, implantation was successful in 93% of all cases. Periprocedural mortality and stroke rates were 1.1% and 0.6%, respectively. The incidences of pericardial effusion/cardiac tamponade and device embolisation were 4% and 0.7%, respectively. At the time of the latest follow-up (up to 40 months), the overall incidence of stroke among all studies was 1.4% per annum. Existing evidence suggests that PLAAO is a relatively safe treatment for patients with AF. However, there is a need for further evaluation of its efficacy in the form of large and well-designed randomised controlled trials
Signal-averaged P wave duration and the dimensions of the atria
No full textDelay of atrial electrical conduction measured as prolonged signal-averaged P wave duration (SAPWD) could be due to atrial enlargement. Here, we aimed to compare different atrial size parameters obtained from echocardiography with the SAPWD measured with a signal-averaged electrocardiogram (SAECG)
Atrial fibrillation recurrence: the roles of hypertension, duration of atrial fibrillation, and prolonged signal-averaged P wave duration
No full textSignal-averaged P wave duration and the long-term risk of permanent atrial fibrillation
No full textBACKGROUND AND AIMS: During atrial fibrillation (AF), the renin-angiotensin-aldosterone system (RAAS) may be activated. In this study, our aim was to evaluate at a long-term follow-up visit the levels of plasma aldosterone and natriuretic peptides as markers of neurohormonal remodeling in patients with earlier, documented AF in relation to present heart rhythm, clinical data, and the left ventricular ejection fraction (LVEF). We hypothesized that increased levels of aldosterone and natriuretic peptides were significantly associated with present AF as markers of RAAS activation during the arrhythmia. METHODS: We studied 158 patients with earlier ECG-documented AF followed by restored sinus rhythm (SR) attending a follow-up visit 2.6 years (mean) after primary inclusion. RESULTS: At follow-up, 93 patients had SR. Heart rhythm at follow-up visit (SR/AF), plasma aldosterone, plasma N-terminal pro Brain Natriuretic Peptide (Nt-proBNP), plasma N-terminal pro Atrial Natriuretic Peptide (Nt-proANP), LVEF, medication, and clinical characteristics were recorded. Standard linear multiple regression analysis including age, sex, weight, hypertension, congestive heart failure, ischemic heart disease, present AF at follow-up, total duration of AF disease, ongoing medication, and the LVEF as explanatory variables showed that only ongoing treatment with diuretics was significantly associated (likelihood ratio test, p = 0.0057) with a raised log-transformed plasma aldosterone, although present AF at follow-up was related to a high aldosterone level (p = 0.09). For the natriuretic peptides, present AF at follow-up (p < 0.0001), age (p < 0.0001), female gender (p = 0.0047), ischemic heart disease (p = 0.0154), and ongoing treatment with sotalol (p = 0.0003) were all independently associated with high log-transformed plasma Nt-proANP. Likewise, present AF at follow-up (p = 0.0008) as well as age (p < 0.0001) were associated with high log-transformed plasma Nt-proBNP. CONCLUSIONS: In patients with earlier AF, AF at long-term follow-up visit was independently associated with raised levels of Nt-proANP and Nt-proBNP and to some extent with plasma aldosterone indicating neurohormonal activation during arrhythmia. Copyright 2007 S. Karger AG, Basel. Udgivelsesdato: Oct. 15OBJECTIVE: To assess the long-term risk of developing permanent AF in relation to the signal-averaged P wave duration (SAPWD) and clinical and echocardiographic characteristics. DESIGN: In an observational study design we studied 131 patients with earlier ECG-documented AF and successfully restored sinus rhythm attending a long-term, follow-up visit at hospital or at home. Established permanent AF was examined in relation to primary clinical, echocardiographic, and electrophysiological parameters. RESULTS: Only prolonged SAPWD (p=0.006) was associated with an increased risk of development of permanent AF. The risk of permanent AF after 3 years follow-up was 0.72 with an SAPWD equal to 180 ms versus 0.39 with a normal SAPWD (130 ms). We found no prognostic effect of age, gender, dilated left atrium, long duration of AF history, or long duration of the most recent episode of AF. Co-existing hypertension reduced the risk of permanent AF; this could be explained by concomitant treatment with angiotensin-converting-enzyme-inhibitors. CONCLUSION: Prolonged SAPWD (a marker of atrial remodelling) appears to be a risk factor for long-term development of permanent AF
