RESUMEN
AIMS: Modern clinical management of patients with an implantable cardioverter defibrillator (ICD) largely consists of remote device monitoring, although a subset is at risk of mental health issues post-implantation. We compared a 12-month web-based intervention consisting of goal setting, monitoring of patients' mental health-with a psychological intervention if needed-psychoeducational support from a nurse, and an online patient forum, with usual care on participants' device acceptance 12 months after implantation. METHODS AND RESULTS: This national, multi-site, two-arm, non-blinded, randomized, controlled, superiority trial enrolled 478 first-time ICD recipients from all 6 implantation centres in Denmark. The primary endpoint was patient device acceptance measured by the Florida Patient Acceptance Survey (FPAS; general score range = 0-100, with higher scores indicating higher device acceptance) 12 months after implantation. Secondary endpoints included symptoms of depression and anxiety. The primary endpoint of device acceptance was not different between groups at 12 months [B = -2.67, 95% confidence interval (CI) (-5.62, 0.29), P = 0.08]. Furthermore, the secondary endpoint analyses showed no significant treatment effect on either depressive [B = -0.49, 95% CI (-1.19; 0.21), P = 0.17] or anxiety symptoms [B = -0.39, 95% CI (-0.96; 0.18), P = 0.18]. CONCLUSION: The web-based intervention as supplement to usual care did not improve patient device acceptance nor symptoms of anxiety and depression compared with usual care. This specific web-based intervention thus cannot be recommended as a standardized intervention in ICD patients.

BACKGROUND: SARS-CoV-2 may trigger both vasculitis and arrhythmias as part of a multisystem inflammatory syndrome described in children as well as in adults following COVID-19 infection with only minor respiratory symptoms. The syndrome denotes a severe dysfunction of one or more extra-pulmonary organ systems, with symptom onset approximately 2-5 weeks after the COVID-19 infection. In the present case, a seemingly intractable ventricular tachycardia preceded by SARS-CoV2 infection was only managed following the diagnosis and management of aortitis. CASE PRESENTATION: A 69-year-old woman was hospitalized due to syncope, following a mild COVID-19 infection. She presented with paroxysmal atrial fibrillation and intermittent ventricular tachycardia interpreted as a septum-triggered bundle branch reentry ventricular tachycardia, unaffected by amiodaron, lidocaine and adenosine. A CT-scan revealed inflammation of the aortic arch, extending into the aortic root. In the following days, the tachycardia progressed to ventricular storm with intermittent third-degree AV block. A temporary pacemaker was implanted, and radiofrequency ablation was performed to both sides of the ventricular septum after which the ventricular tachycardia was non-inducible. Following supplemental prednisolone treatment, cardiac symptoms and arrythmia subsided, but recurred after tapering. Long-term prednisolone treatment was therefore initiated with no relapse in the following 14 months. CONCLUSION: We present a rare case of aortitis complicated with life-threatening ventricular tachycardia presided by Covid-19 infection without major respiratory symptoms. Given a known normal AV conduction prior to the COVID-19 infection, it seems likely that the ensuing aortitis in turn affected the septal myocardium, enabling the reentry tachycardia. Generally, bundle branch reentry tachycardia is best treated with radiofrequency ablation, but if it is due to aortitis with myocardial affection, long-term anti-inflammatory treatment is mandatory to prevent relapse and assure arrhythmia control. Our case highlights importance to recognize the existence of the multisystem inflammatory syndrome in adults (MIS-A) following COVID-19 infection in patients with alarming cardiovascular symptoms. The case shows that the early use of an CT-scan was crucial for both proper diagnosis and treatment option.

AIMS: Patients are restricted from driving following implantable cardioverter defibrillator (ICD) implantation or shock. We sought to investigate how many patients are aware of, and adhere to, the driving restrictions, and what proportion experience an ICD shock or other cardiac symptoms while driving. METHODS AND RESULTS: We performed a nationwide survey of all living Danish residents 18 years or older who received a first-time ICD between 2013 and 2016 (n = 3913) and linked their responses with nationwide registers. Of 2741 respondents (47% primary prevention, 83% male, median age 67 years), 2513 (92%) held a valid driver's license at ICD implantation, 175 (7%) of whom had a license for professional driving. Many drivers were unaware of driving restrictions: primary prevention 58%; secondary prevention 36%; post-appropriate shock 28%; professional drivers 55%. Almost all (94%) resumed non-professional driving after ICD implantation, more than one-third during the restricted period; 35% resumed professional driving. During a median follow-up of 2.3 years, 5 (0.2%) reported receiving an ICD shock while driving, one of which resulted in a traffic accident. The estimated risk of harm was 0.0002% per person-year. CONCLUSION: In this nationwide study, many ICD patients were unaware of driving restrictions, and more than one third resumed driving during a driving restriction period. However, the rate of reported ICD shocks while driving was very low.

AIMS: Commonly, a dysfunctional defibrillator lead is abandoned and a new lead is implanted. Long-term follow-up data on abandoned leads are sparse. We aimed to investigate the incidence and reasons for extraction of abandoned defibrillator leads in a nationwide cohort and to describe extraction procedure-related complications. METHODS AND RESULTS: All abandoned transvenous defibrillator leads were identified in the Danish Pacemaker and ICD Register from 1991 to 2019. The event-free survival of abandoned defibrillator leads was studied, and medical records of patients with interventions on abandoned defibrillator leads were audited for procedure-related data. We identified 740 abandoned defibrillator leads. Meantime from implantation to abandonment was 7.2 ± 3.8 years with mean patient age at abandonment of 66.5 ± 13.7 years. During a mean follow-up after abandonment of 4.4 ± 3.1 years, 65 (8.8%) abandoned defibrillator leads were extracted. Most frequent reason for extraction was infection (pocket and systemic) in 41 (63%) patients. Procedural outcome after lead extraction was clinical success in 63 (97%) patients. Minor complications occurred in 3 (5%) patients, and major complications in 1 (2%) patient. No patient died from complication to the procedure during 30-day follow-up after extraction. CONCLUSION: More than 90% of abandoned defibrillator leads do not need to be extracted during long-term follow-up. The most common indication for extraction is infection. Abandoned defibrillator leads can be extracted with high clinical success rate and low risk of major complications at high-volume centres.

AIM: The Danish Study to Assess the Efficacy of Implantable Cardioverter-Defibrillators (ICD) in Patients with Non-ischaemic Systolic Heart Failure (HF) on Mortality (DANISH) found no overall effect on all-cause mortality. The effect of ICD implantation on health-related quality of life (HRQoL) remains to be established as previous trials have demonstrated conflicting results. We investigated the impact of ICD implantation on HRQoL in patients with non-ischaemic systolic HF, a prespecified secondary endpoint in DANISH. METHODS AND RESULTS: In DANISH, a total of 1116 patients with non-ischaemic systolic HF were randomly assigned (1:1) to ICD implantation or usual clinical care (control). Patients completed disease-specific HRQoL as assessed by Minnesota Living with Heart Failure Questionnaire (MLHFQ; 0-105, high indicating worse). Changes in HRQoL 8 months after randomization were assessed with a mixed-effects model. At randomization, MLHFQ was completed by 935 (84%) patients (n = 472 in the ICD group and n = 463 in the control group) and was reassessed in 274 (58%) and 292 (63%) patients, respectively after 8 months for the primary analysis. Patients in the ICD group vs. the control group had similar improvements in MLHFQ after 8 months [least square mean -7.0 vs. -4.2 (P = 0.13)]. A clinically relevant improvement (decrease ≥5) in the MLHFQ overall score at 8 months was observed in 151 patients in the ICD group and 148 patients in the control group [55% vs. 51%, respectively (P = 0.25)]. CONCLUSION: Implantable cardioverter-defibrillator implantation in patients with non-ischaemic systolic HF did not significantly alter HRQoL compared with patients randomized to usual clinical care.

BACKGROUND: In Denmark and other countries, there has been a shift in the management of patients with an implantable cardioverter defibrillator (ICD) with remote device monitoring largely replacing in-hospital visits. Less patient-nurse and patient-physician interaction may lead to gaps in patients' quality of care and impede patients' adaptation to living successfully with the ICD. A comprehensive eHealth intervention that include goal-setting, monitoring of symptoms of depression, anxiety, and quality of life, psychological treatment, information provision, supportive tools, online dialogues with nursing staff and access to an online community network, may help fill these gaps and be particularly beneficial to patients who suffer from anxiety and depression. This study will evaluate the effectiveness of the ACQUIRE-ICD care innovation, a comprehensive and interactive eHealth intervention, on patient-reported and clinical outcomes. METHODS: The ACQUIRE-ICD study is a multicenter, prospective, two-arm, unblinded randomised controlled superiority trial that will enroll 478 patients implanted with a first-time ICD or ICD with cardiac synchronisation therapy (CRT-D) from the six implanting centers in Denmark. The trial will evaluate the clinical effectiveness and cost-effectiveness of the ACQUIRE-ICD care innovation, as add-on to usual care compared with usual care alone. The primary endpoint, device acceptance, assessed with the Florida Patient Acceptance Survey, is evaluated at 12 months' post implant. Secondary endpoints, evaluated at 12 and 24 months' post implant, include patient-reported outcomes, return to work, time to first ICD therapy and first hospitalisation, mortality and cost-effectiveness. DISCUSSION: The effectiveness of a comprehensive and interactive eHealth intervention that relies on patient-centred and personalised tools offered via a web-based platform targeted to patients with an ICD has not been assessed so far. The ACQUIRE-ICD care innovation promotes and facilitates that patients become active participants in the management of their disease, and as such addresses the need for a more patient-centered disease-management approach. If the care innovation proves to be beneficial to patients, it may not only increase patient empowerment and quality of life but also free up time for clinicians to care for more patients. TRIAL REGISTRATION: The trial has been registered on https://clinicaltrials.gov/ct2/show/NCT02976961 on November 30, 2016 with registration number [ NCT02976961 ].

INTRODUCTION: Psychological adaption after pacemaker implantation can be challenging in patients with psychiatric disease. Suicide by self-removal of a permanent pacemaker system is a rare phenomenon described in a few cases in patients with psychiatric disorders. METHODS AND RESULTS: We describe a case of attempted suicide by complete self-removal of a 12-year-old permanent pacemaker system in a 70-year-old male patient with a bipolar disorder and a history of previous suicide attempts. CONCLUSIONS: Suicide attempt by self-removal of a permanent pacemaker system is very rare. In patients with a history of psychiatric disease and previous suicide attempts, careful information about the function of a pacemaker should be given.

BACKGROUND AND AIM: There are a paucity of studies investigating workforce affiliation in connection with first-time ICD-implantation. This study explored workforce affiliation and risk markers associated with not returning to work in patients with ICDs. METHODS: Using the nationwide Danish registers, patients with a first-time ICD-implantation between 2007-2017 and of working age (30-65 years) were identified. Descriptive statistic and logistic regression models were used to describe workforce affiliation and to estimate risk markers associated with not returning to work, respectively. All analyses were stratified by indication for implantation (primary and secondary prevention). RESULTS: Of the 4,659 ICD-patients of working age, 3,300 patients (71%) were members of the workforce (employed, on sick leave or unemployed) (primary: 1428 (43%); secondary:1872 (57%)). At baseline, 842 primary and 1477 secondary prevention ICD-patients were employed. Of those employed at baseline, 81% primary and 75% secondary prevention ICD-patients returned to work within one-year, whereof more than 80% remained employed the following year. Among patients receiving sick leave benefits at baseline, 25% were employed after one-year. Risk markers of not returning to work were 'younger age' in primary prevention ICD-patients, while 'female sex', 'LVEF ≤40', 'lower income' and '≥3 comorbidities' were risk markers in secondary prevention ICD-patients. Lower educational level was a risk marker in both patient groups. CONCLUSIONS: High return-to-work proportions following ICD-implantation, with a subsequent high level of employment maintenance were found. Several significant risk markers of not returning to work were identified including 'lower educational level', that posed a risk in both patient groups.Trial registration number: Capital Region of Denmark, P-2019-051.
RESUMEN
OBJECTIVE: To examine the gradual association between self-reported health status and mortality in patients with heart failure (HF) as current research has focused on poor health status and increased risk of mortality. METHOD: This is a substudy of the DANISH (Defibrillator Implantation in Patients with Nonischemic Systolic HF) trial in which 1116 patients were randomized to receive or not receive an implantable cardioverter-defibrillator. Health status was assessed by a single question of the Short-Form 36. Patients were classified as having excellent/very good, good, fair (reference) or poor health status. We assessed the association between health status and mortality using multivariable Cox proportional hazard models. RESULTS: Self-reported health status was completed by 943 (84%) patients at randomization with a median follow-up of 67 months and a health status distribution of; excellent/very good (n = 79, 8%), good (n = 369, 39%), fair (n = 409, 43%), and poor (n = 86, 9%). All-cause mortality (death events/ 100 person-years) occurred with gradual differences according to health status from excellent/ very good (2.14), good (3.74), fair (5.21) to poor health status (5.57). The gradual difference yielded a crude hazard ratio (HR) of 0.40, 95% CI 0.20-0.80 (adjusted HR 0.47 (95% CI 0.23-0.95) for excellent/ very good health status, HR 0.71, 95% CI 0.52-0.97 (adjusted HR 0.78 (95% CI 0.56-1.08) for good health status. Poor being worse than fair health status yielded a crude HR of 1.07, 95% CI 0.67-1.69. CONCLUSION: Excellent/very good self-reported health status as assessed by a single question was associated with lower long-term mortality in patients with HF.
RESUMEN
BACKGROUND: The DANish StUdy of impaired glucose metabolism in the settings of cardiac rehabilitation (DANSUK) examined the effect of an intensified multifactorial intervention on risk factor profile in 104 patients with type 2 diabetes mellitus (T2DM) or impaired glucose tolerance (IGT) attending hospital-based outpatient comprehensive cardiac rehabilitation (CCR) compared to usual care (UC). METHODS: Patients with ischemic heart disease (67%), congestive heart failure (7%), or at least 3 risk factors for ischemic heart disease (26%) discharged from 1 coronary care unit were referred to CCR. Of 473 eligible individuals, 201 agreed to participate in the study, and 52% had T2DM or IGT. Patients randomized to CCR received a stepwise implementation of behavioral modification and pharmacotherapy. RESULTS: After 1 year, patients with T2DM in the CCR group experienced a mean change in HbA1c of -0.65% +/- 0.9% compared with a mean change of -0.08% +/- 0.7% in the UC group (P < .05). Mean change in systolic and diastolic blood pressures was -8 +/- 15 and -5 +/- 9 mm Hg in the CCR group compared with a mean change of -0.8 +/- 15 and -0.2 +/- 7 mm Hg in the UC group (P < .05). Patients with IGT attending CCR obtained a significantly higher exercise capacity compared with patients in the UC group (P < .05). CONCLUSIONS: In a group of patients with impaired glucose metabolism attending CCR, an intensified multifactorial intervention with an integrated diabetes module was more efficient in improving risk factor control than UC. Besides the improvement in the exercise capacity of patients with IGT, in patients with T2DM, both HbA1c and blood pressure were lowered to a level that has been shown to reduce both cardiac and diabetic complications. These findings have important implications for patients with impaired glucose metabolism in the future settings of CCR.

BACKGROUND: Lifestyle and pharmacological interventions can delay the progression of impaired glucose tolerance (IGT) to type 2 diabetes (T2DM), and there is growing evidence that earlier detection of T2DM and intensified risk factor management may result in improved cardiovascular morbidity and mortality. We studied the prevalence of impaired glucose metabolism (T2DM, IGT and impaired fasting glucose; IFG) in patients referred to cardiac rehabilitation, and further studied whether we could identify groups in which an oral glucose tolerance test (OGTT) need not be performed. METHODS: As part of a cardiac rehabilitation trial, 201 patients participated. Patients without a diagnosis of T2DM (N=159) underwent an OGTT 3 months after inclusion. RESULTS: Forty-two patients (21%) had known T2DM at enrolment. Based on the OGTT, 26 patients (13%) had unrecognized T2DM, 36 (18%) had IGT and 19 (9%) were diagnosed with isolated IFG according to the World Health Organization definition. Using fasting plasma glucose alone, 19% of the patients with unrecognized T2DM and two-thirds of patients with IGT would be misclassified. Using IFG as a means to detect IGT showed a sensitivity of only 33% and a positive predictive value of 39%. CONCLUSION: More than 60% of the patients (123/201) referred to cardiac rehabilitation had impaired glucose metabolism and 18% of the screened patients (29/159) would be misclassified if an OGTT was omitted. IFG and IGT did not identify the same patients or the same cardiovascular risk profile. An OGTT test should therefore be considered a constituent part of routine care management in cardiac rehabilitation settings.
