Perceived Benefits of Implantable Cardioverter Defibrillator Implantation among Heart Failure Patients and Its Relation to Quality of Life: A Cross-Sectional Study

Information provision and follow-up of French patients with implantable cardioverter-defibrillators: The APODEC survey

BACKGROUND

Implantable cardioverter-defibrillators reduce mortality, but the electric shocks delivered can impact the patient's quality of life. Patient education is an efficient way to reduce the stress related to both the device and the disease.

AIMS

We assessed the evolution of knowledge and satisfaction of implantable cardioverter-defibrillator recipients regarding their cardiac disease, implantable cardioverter-defibrillator implantation, follow-up complications, remote monitoring and daily life recommendations. Quality of life, implantable cardioverter-defibrillator-related stress levels and remote monitoring benefits were also evaluated.

METHODS

A self-administered questionnaire of 43 items was published on the French Association of Cardiac Electrical Device Wearers (APODEC) website and sent to registered patients.

RESULTS

Overall, 330 patients completed the survey. Physicians were the patients' principal information source regarding their cardiac disease (86.7%) and implantable cardioverter-defibrillator (93.3%), and 90% looked for further information after the procedure, mainly on websites (78.8%). More than half of the patients were not sufficiently informed about implantable cardioverter-defibrillators before implantation (61.2%). In the patients' opinion, the best sources of further information were their physician (81.8%), patient associations (63.6%) and the Internet (45.8%). Although patient knowledge increased during follow-up, their knowledge could be improved regarding daily life with an implantable cardioverter-defibrillator (52.1%), remote monitoring (34.2%) and their cardiac disease (32.1%). Remote monitoring follow-up was used by 92.1% of patients and mostly improved their peace of mind (67.8%). Implantable cardioverter-defibrillator shocks were associated with major stress for patients receiving them (46.6%).

CONCLUSION

These findings highlight the lack of information provided to implantable cardioverter-defibrillator recipients before implantation, a concerning issue to be addressed in the near future.

A Qualitative Analysis of Patient-Related Factors Associated With Implantable Cardioverter Defibrillator Acceptance

INTRODUCTION

Patient-related factors determining implantable cardioverter-defibrillator (ICD) use for primary prevention of sudden cardiac death in patients with cardiomyopathy have not been well explored. To assess race and sex differences regarding ICD preferences in this patient population, we sought to analyze a diverse cohort of patients with heart failure (HF) with reduced ejection fraction.

METHODS

We conducted qualitative interviews of 28 adults with severe HF and either (1) an ICD or (2) no ICD. Interviews were recorded, transcribed, and coded using an inductively developed codebook by independent investigators. Coding was fully adjudicated and transcripts were reviewed to identify themes.

RESULTS

We recruited patients between 12/2015 and 06/2017, primarily from the outpatient cardiology clinic (24/28 = 86%). Half were women (50%) and 13/28 (46%) were black. Eight did not have an ICD. Neither race nor sex was associated with ICD. Four themes emerged: (1) HF requiring an ICD is profoundly disruptive to patients' lives; (2) patients had positive, yet unrealistic opinions of ICDs; or (3) Patients had negative/ambivalent opinions of ICDs; (4) medical decision-making included aspects of shared decision-making and informed consent.

CONCLUSIONS

Patients without ICDs perceived less benefit from ICDs and had less decision support. Participants viewed conversations with providers as insufficient. Needed interventions include the development and validation of processes for informed decisions about ICDs.

Perception of the Risk of Stroke and the Risks and Benefits of Oral Anticoagulation for Stroke Prevention in Patients With Atrial Fibrillation: A Cross-Sectional Study

OBJECTIVE

To assess the perception of the risk of stroke and the risks and benefits of oral anticoagulation (OAC) in patients with atrial fibrillation (AF).

PATIENTS AND METHODS

Consecutive patients with chronic AF who presented for an outpatient cardiology visit or were admitted to a noncritical care cardiology ward service from September 15 through December 20, 2017, were invited to participate in this survey. Participants were asked to estimate their stroke risk without OAC and bleeding risk with OAC using a quantitative risk scale. The reported values were compared with subjectively estimated risks derived from the CHA₂DS₂-VASc and HAS-BLED scores. Similarly, we compared patient perception of the stroke risk reduction afforded with OAC compared with what is reported in the literature.

RESULTS

A total of 227 patients were included in the analysis. The mean ± SD CHA₂DS₂-VASc score was 4.3±1.6, and HAS-BLED score was 2.3±1.2. Atrial fibrillation was paroxysmal in 53.3% and persistent/permanent in 46.7%. There was a negligible correlation between patient perceived and estimated risk of stroke (r=0.07; P=.32), and bleeding (r=0.16; P=.02). Most patients overestimated their risks of stroke and bleeding: 120 patients (52.9%) perceived an annual stroke risk greater than 20%, and 115 (53.5%) perceived an annual bleeding risk with OAC greater than 10%. Most patients (n=204; 89.9%) perceived that OAC would reduce their annual stroke risk by at least 50%.

CONCLUSION

Perceived risks of stroke and bleeding are markedly overestimated in most patients with AF. Further research is needed to discern the root causes and to identify effective methods of bridging this alarming disparity.

Nonpharmacological interventions to improve quality of life in heart failure: an integrative review

Objective:

to identify articles that assessed the effectiveness or efficacy of nonpharmacological interventions to improve quality of life of people with heart failure in the literature.

Method:

an integrative literature review was performed in Lilacs, MedLine and SciELO databases, including randomized or nonrandomized clinical trials and quasi-experimental studies published between 2003 and 2014, in Portuguese, English or Spanish.

Results:

twenty-three studies were included. The categories of nonpharmacological interventions that improved quality of life of people with heart failure were: Remote health monitoring, Instructions on health practices, Physical activity follow-up and Traditional Chinese Medicine practices.

Conclusion:

these results can guide the selection of interventions to be implemented by health professionals that treat people with heart failure. Future systematic reviews with meta-analyses are needed in order to identify the most effective interventions for improving these individuals' quality of life.
