    Heart failure (HF) hospitalisations due to decompensation are associated with shorter lifeexpectancy and lower quality of life. These hospitalisations pose a significant burden on the patients,doctors and healthcare resources. Early detection of an upcoming episode of decompensationmay facilitate timely optimisation of the ambulatory medical treatment and thereby prevent heartfailure-related hospitalisations. The HeartLogicTM algorithm combines data from five sensors ofcardiac implantable electronic devices into a cumulative index value. It has been developed for earlydetection of fluid retention in heart failure patients. This review aims to provide an overview of thecurrent literature and experience with the HeartLogicTM algorithm, illustrate how the index can beimplemented in daily clinical practice and discuss ongoing studies and potential future developmentsof interest.Cardiolog

    Fusion cardiac resynchronization therapy in an left ventricular assist device patient from two devices and crossing leads: a case report

    Background Cardiac implanted electronic devices (CIED) have significantly improved the survival and quality of life in heart failure patients. Although implantable cardioverter-defibrillators (ICD) and cardiac resynchronization therapy (CRT) have a major role in patients with moderate to severe heart failure symptoms, the role of these devices in patients with a left ventricular assist device (LVAD) is not yet well defined. The burden of CIED-related procedures in patients with an LVAD is high. The price of lead malfunctions and pocket complications requires creative approaches to tackle CIED-related issues in this patient population.Case summary Here, we describe the clinical course of a 67-year-old ventricular pacing dependent LVAD patient with an ICD indication based on recurrent monomorphic ventricular tachycardias and a CRT indication due to previous deterioration of (right-sided) heart failure in the absence of biventricular pacing. We were confronted with impending right ventricular lead failure and bilateral venous access problems due to chronic subclavian vein occlusion in a patient with a total of five transvenous leads, therapeutic anticoagulation, and pronounced thoracic collaterals. We sought for a creative solution to be able to deliver effective biventricular fusion pacing with the existing leads from two contralateral pulse generators resulting in biventricular fusion pacing. This provided the solution to deliver effective CRT.Discussion This case illustrates the complexity of care and CIED-related decision-making in pacing dependent LVAD patients, in particularly those with an ICD and CRT indication.Cardiolog

    Peritoneal dialysis improves quality-of-life in a left ventricular assist device destination therapy patient: a case report

    Background Progressive renal insufficiency is frequent in heart failure patients with a left ventricular assist device (LVAD). The optimal strategy for long-term dialysis in LVAD patients and its effect on quality-of-life in these patients remain to be determined.Case summary Our 55-year-old patient with pre-existing renal insufficiency received an LVAD as destination therapy because of advanced ischaemic heart failure. Six years after implantation, he developed end-stage renal disease for which peritoneal dialysis (PD) was initiated. Left ventricular assist device flow alterations during uttrafiltration did not cause clinical or technical problems. The patient's exercise capacity increased and quality-of-life improved. Over 7.5 years after LVAD implantation and 16 months after PD initiation, he died from encephalitis.Discussion Despite initial improvement, renal function often gradually decreases after LVAD implantation. Data on long-term renal replacement therapy in LVAD patients are limited. Haemodialysis is most commonly applied. Conceptually, however, PD has advantages over haemodialysis including less bloodstream infections, less haemodynamic shifts, and the comfort of the ambulant setting. This case illustrates that PD in an LVAD patient is feasible and improves quality-of-life. Key factors contributing to successful PD in LVAD patients may be a good right ventricular function and close cardiology-nephrology collaboration.Cardiolog

    Prognostic value of natriuretic peptides for all-cause mortality, right ventricular failure, major adverse events, and myocardial recovery in advanced heart failure patients receiving a left ventricular assist device: a systematic review

    Get PDF
    Aims: Major adverse event (MAE) rates during left ventricular assist device (LVAD) therapy in advanced heart failure (HF) patients are high, and impair quality of life and survival. Prediction and risk stratification of MAEs in order to improve patient selection and thereby outcome during LVAD therapy is therefore warranted. Circulating natriuretic peptides (NPs) are strong predictors of MAEs and mortality in chronic HF patients. However, whether NPs can identify patients who are at risk of MAEs and mortality or tend toward myocardial recovery after LVAD implantation is unclear. The aim of this systematic review is to analyze the prognostic value of circulating NP levels before LVAD implantation for all-cause mortality, MAEs and myocardial recovery after LVAD implantation.Methods and Results: Electronic databases were searched for studies analyzing circulating NP in adults with advanced HF before LVAD implantation in relation to mortality, MAEs, or myocardial recovery after LVAD implantation. Twenty-four studies published between 2008 and 2021 were included. Follow-up duration ranged from 48 hours to 5 years. Study sample size ranged from 14 to 15,138 patients. Natriuretic peptide levels were not predictive of all-cause mortality. However, NPs were predictive of right ventricular failure (RVF) and MAEs such as ventricular arrhythmias, moderate or severe aortic regurgitation, and all-cause rehospitalization. No relation between NPs and myocardial recovery was found.Conclusion: This systematic review found that NP levels before LVAD implantation are not predictive of all-cause mortality after LVAD implantation. Thus, NP levels may be of limited value in patient selection for LVAD therapy. However, NPs help in risk stratification of MAEs and may be used to identify patients who are at risk for RVF, ventricular arrhythmias, moderate or severe aortic regurgitation, and all-cause rehospitalization after LVAD implantation.Cardiolog

    Aim To analyse non-ST-elevation myocardial infarction (NSTEMI) care in the Netherlands and to identify modifiable factors to improve NSTEMI healthcare. Methods This retrospective cohort study analysed hospital and pharmacy claims data of all NSTEMI patients in the Netherlands in 2015. The effect of percutaneous coronary intervention (PCI) during hospitalisation on 1-year mortality was investigated in the subcohort alive 4 days after NSTEMI. The effect of medical treatment on 1-year mortality was assessed in the subcohort alive 30 days after NSTEMI. The effect of age, gender and co-morbidities was evaluated. PCI during hospitalisation was defined as PCI within 72x202f;h after NSTEMI and optimal medical treatment was defined as the combined use of an aspirin species, P2Y(12) inhibitor, statin, beta-blocker and angiotensin converting enzyme inhibitor/angiotensin II receptor blocker, started within 30 days after NSTEMI. Results Data from 17,997 NSTEMI patients (age 69.6 (SDx202f;= 12.8) years, 64% male) were analysed. Of the patients alive 4 days after NSTEMI, 43% had a PCI during hospitalisation and 1-year mortality was 10%. In the subcohort alive 30 days after NSTEMI, 47% of patients were receiving optimal medical treatment at 30 days and 1-year mortality was 7%. PCI during hospitalisation (odds ratio (OR) 0.42; 95% confidence interval (CI) 0.37-0.48) and optimal medical treatment (OR 0.59; 95% CI 0.51-0.67) were associated with a lower 1-year mortality. Conclusion In Dutch NSTEMI patients, use of PCI during hospitalisation and prescription of optimal medical treatment are modest. As both are independently associated with a lower 1-year mortality, this study provides direction on how to improve the quality of NSTEMI healthcare in the Netherlands.Cardiolog

    Emergency medical services evaluations for chest pain during first COVID-19 lockdown in Hollands-Midden, the Netherlands

    Get PDF
    Objective To assess whether the COVID-19 lockdown in 2020 had negative indirect health effects, as people seem to have been reluctant to seek medical care. Methods All emergency medical services (EMS) transports for chest pain or out-of-hospital cardiac arrest (OHCA) in the Dutch region Hollands-Midden (population served > 800,000) were evaluated during the initial 6 weeks of the COVID-19 lockdown and during the same time period in 2019. The primary endpoint was the number of evaluated chest pain patients in both cohorts. In addition, the number of EMS evaluations of ST-elevation myocardial infarction (STEMI) and OHCA were assessed. Results During the COVID-19 lockdown period, the EMS evaluated 927 chest pain patients (49% male, age 62 +/- 17 years) compared with 1041 patients (51% male, 63 +/- 17 years) in the same period in 2019, which corresponded with a significant relative risk (RR) reduction of 0.88 (95% confidence interval (CI) 0.81-0.96). Similarly, there was a significant reduction in the number of STEMI patients (RR 0.52, 95% CI 0.32-0.85), the incidence of OHCA remained unchanged (RR 1.23, 95% CI 0.83-1.83). Conclusion During the first COVID-19 lockdown, there was a significant reduction in the number of patients with chest pain or STEMI evaluated by the EMS, while the incidence of OHCA remained similar. Although the reason for the decrease in chest pain and STEMI consultations is not entirely clear, more attention should be paid to the importance of contacting the EMS in case of suspected cardiac symptoms in possible future lockdowns.Cardiolog

    Background: Thoracic irradiation is one of the cornerstones of Hodgkin lymphoma (HL) treatment, which contributes to high rates of long-term survivorship, but begets a life-long increased risk of heart disease including heart failure. At the cardio-oncology (CO) clinic, persistent sinus tachycardia or elevated resting heart rate (RHR) is frequently observed in these patients. The aim of this study was to evaluate the relation between RHR and left ventricular (LV) dysfunction.Methods: In 75 HL survivors visiting our CO-clinic echocardiographic evaluation of LV systolic and diastolic function including global longitudinal strain (GLS) was performed to assess subclinical LV dysfunction.Results: Median age of HL diagnosis was 24 [25th-75th percentile: 19,29] years with a 17 [12,25] year interval to CO-clinic visit and 31 patients (41%) were male. Average RHR was 78 +/- 14 bpm and 40% of patients (N = 30) had an elevated RHR defined as >= 80 bpm. While there was no difference in LV ejection fraction (55.6 +/- 4.3 vs. 54.8 +/- 6.6; p = 0.543), patients with elevated RHR had abnormal GLS (-15.9% vs. -18.3%, p = 0.045) and higher prevalence of diastolic dysfunction (73.3% vs. 46.7%; p = 0.022). GLS, E/e' ratio and presence of diastolic dysfunction were independently associated with RHR when correcting for age, sex and mantle field irradiation. A significant improvement was observed of the RHR association model with solely extracardiac confounders when LV-function parameters were added to the model (F-statistic = 6.36, p = 0.003).Conclusions: This study indicates RHR as a possible marker for subclinical LV-dysfunction in HL survivors.

    Referral and participation in cardiac rehabilitation of patients following acute coronary syndrome: lessons learned

    Get PDF
    Purpose: Cardiac rehabilitation (CR) after hospitalization for acute coronary syndrome (ACS) has shown to reduce mortality, readmissions, and improve quality of life. CR is recommended by international guidelines but previous studies have shown low participation rates. Systematic CR referral might improve CR participation.Methods: The present study evaluates CR referral and CR participation of patients hospitalized for ACS in 2017 and treated according to local protocol, which includes systematic CR referral. Participation rate was divided into a group that finished the CR program and drop outs. In addition, factors associated with CR referral and participation rate were evaluated.Results: A total of 469 patients eligible for CR were included in the study, of which 377 (80%) were referred for CR and 353 (75%) participated in CR. Ninety percent of participants completed the CR pro-gram. Factors independently associated with CR referral included age (50-60 year vs. > 70 year: odds ratio [OR] 4.7, 95% confidence interval [CI] 1.98-11.2), diagnosis (ST-elevation myocardial infarction vs. unstable angina: OR 17.7, CI 7.59-41.7), previous cardiovascular disease (OR 0.4, CI 0.19-0.73) and left ventricular dysfunction vs. normal function (OR 2.2, CI 1.11-4.52). A larger distance to the CR center was associated with lower CR participation ( 20 km: OR 3.1, CI 1.20-7.72).Conclusions: Systematic CR referral in ACS patients results in high CR referral (80%) and participation (75%) rates. CR adherence might be further improved by increasing CR referral, especially in older patients and patients with NSTEMI or unstable angina. (c) 2021 The Authors. Published by Elsevier B.V.Cardiolog

    Importance Smart technology via smartphone-compatible devices might improve blood pressure (BP) regulation in patients after myocardial infarction. Objectives To investigate whether smart technology in clinical practice can improve BP regulation and to evaluate the feasibility of such an intervention. Design, Setting, and Participants This study was an investigator-initiated, single-center, nonblinded, feasibility, randomized clinical trial conducted at the Department of Cardiology of the Leiden University Medical Center between May 2016 and December 2018. Two hundred patients, who were admitted with either ST-segment elevation myocardial infarction or non-ST-segment acute coronary syndrome, were randomized in a 1:1 fashion between follow-up groups using smart technology and regular care. Statistical analysis was performed from January 2019 to March 2019. Interventions For patients randomized to regular care, 4 physical outpatient clinic visits were scheduled in the year following the initial event. In the intervention group, patients were given 4 smartphone-compatible devices (weight scale, BP monitor, rhythm monitor, and step counter). In addition, 2 in-person outpatient clinic visits were replaced by electronic visits. Main Outcomes and Measures The primary outcome was BP control. Secondary outcomes, as a parameter of feasibility, included patient satisfaction (general questionnaire and smart technology-specific questionnaire), measurement adherence, all-cause mortality, and hospitalizations for nonfatal adverse cardiac events. Results In total, 200 patients (median age, 59.7 years [interquartile range, 52.9-65.6 years]; 156 men [78%]) were included, of whom 100 were randomized to the intervention group and 100 to the control group. After 1 year, 79% of patients in the intervention group had controlled BP vs 76% of patients in the control group (P = .64). General satisfaction with care was the same between groups (mean [SD] scores, 82.6 [14.1] vs 82.0 [15.1]; P = .88). The all-cause mortality rate was 2% in both groups (P > .99). A total of 20 hospitalizations for nonfatal adverse cardiac events occurred (8 in the intervention group and 12 in the control group). Of all patients, 32% sent in measurements each week, with 63% sending data for more than 80% of the weeks they participated in the trial. In the intervention group only, 90.3% of patients were satisfied with the smart technology intervention. Conclusions and Relevance These findings suggest that smart technology yields similar percentages of patients with regulated BP compared with the standard of care. Such an intervention is feasible in clinical practice and is accepted by patients. More research is mandatory to improve patient selection of such an intervention.Cardiolog
