Lifestyle interventions after ablation for atrial fibrillation: a systematic review.

BACKGROUND: Risk factors of atrial fibrillation include diabetes, obesity and physical inactivity. Positive effects such as decreased atrial fibrillation burden have been reported for atrial fibrillation patients who have participated in lifestyle changing interventions after atrial fibrillation ablation treatment. AIM: The aim of this study was to assess the evidence on the benefits and harms of lifestyle and risk factor management interventions in patients undergoing atrial fibrillation ablation. METHOD: Our systematic review searched MEDLINE, EMBASE, CINAHL, Psychinfo, Web of Science and CENTRAL using key terms related to atrial fibrillation and lifestyle, including interventional trials. The primary outcomes were mortality and serious adverse events. Random effects meta-analyses of outcomes were conducted when appropriate. RESULTS: Two randomised controlled trials and two non-randomised interventional trials with a total of 498 patients were included. Six primary events were reported for the intervention groups and five events for the control groups (relative risk of 1.03, 95% confidence interval (CI) 0.3 to 3.1, I2 0%, P = 0.537). Effects in favour of the intervention groups were found for atrial fibrillation frequency (0.82 points, 95% CI -1.60 to -0.03, I2 87.3%, P = 0.005), atrial fibrillation duration (-0.76 points, 95% CI -1.64 to 0.12, I2 89.1%, P = 0.002) and body mass index (-5.40 kg/m2, 95% CI 6.22 to -2.57, I2 83.9%, P = 0.013). Risk of bias in the four studies was judged to be low to moderate. CONCLUSION: Lifestyle changing interventions seem to have a positive effect on outcomes relevant to patients undergoing atrial fibrillation ablation, but the included studies were small, interventions were inhomogeneous, and the quality of evidence was low to moderate. More studies are warranted.

Assessment of long-term quality of life after cavotricuspid isthmus ablation for typical atrial flutter.

BACKGROUND: Cavotricuspid isthmus (CTI) ablation is the treatment of choice in preventing recurrences of typical atrial flutter (AFl). However, little is known about long-term quality of life (QoL) after CTI ablation. METHODS AND RESULTS: From 01/2003 to 05/2005, 94 patients who consecutively underwent typical AFl ablation were included in the study. An SF-36 health questionnaire was self-administered before ablation and at follow-up. Transformed scores were calculated, adjusted for age and sex and then normalized and standardized for the Spanish population. Additionally, the minimal important differences (MID) were calculated to assess the smallest change in QoL that patients perceived as positive. A linear regression model was constructed to assess long-term QoL predictors. All SF-36 scales were lower than Spanish population scores. After a mean (SD) follow-up of 6.25 (0.5) years, all scales, except Bodily Pain, were higher than baseline. There was a significant difference for Physical Role (46.4 vs. 38.6, p < 0.001), Vitality (44.4 vs. 41.9, p = 0.038) and Mental Health (46.1 vs. 42.0, p = 0.001). However, only Physical Role achieved the criteria for MID. Recurrence of AFl, basal QoL, history of diabetes mellitus, atrial fibrillation and oral anticoagulation were predictors of long-term QoL. CONCLUSION: CTI ablation provides a significant improvement in long-term QoL for the dimensions of Physical Role, Vitality and Mental Health, although the smallest positive change that patients perceive as positive was only observed for Physical Role. Previous diabetes mellitus, atrial fibrillation, oral anticoagulation, basal QoL and AFl recurrence were determinants of a worse long-term QoL.

Socio-economic impact of endovenous thermal ablation techniques.

Varicose veins are common and cause extensive morbidity; however, the value of treatment is under-appreciated. Many procedures allow the treatment of varicose veins with minimal cost and extensive literature supporting differing minimally invasive approaches. In this article, we investigate the current literature regarding treatment options, clinical outcome and the cost-benefit economics associated with varicose vein treatment. The practice of defining clinical outcome with quality of life (QOL) assessment is explained to provide valid concepts of treatment success beyond occlusion rates.

Adverse psychological effects and costs associated with waiting for radiofrequency ablation.

BACKGROUND: Radiofrequency ablation (RFA) is undertaken as a potentially curative treatment for a variety of heart rhythm disturbances. Previous studies have demonstrated improved quality of life and reduced symptoms after ablation. In many health care environments waiting lists exist for scheduling of procedures. However, the psychological effects of waiting for radiofrequency ablation have not previously been assessed. We hypothesized that waiting for this intervention may be associated with increased psychological morbidity and health care costs. METHODS: Ninety-two patients scheduled for elective RFA completed repeated questionnaires comprising the Medical Outcomes Short Form 36, Hospital Anxiety and Depression Scale, and an in-house questionnaire designed to assess the burden of symptoms related to arrhythmia (arrhythmia-related burden score). Mean scores were generated and compared at time points while waiting, before and after the procedure. Regression analyses were carried out to identify predictors of increased psychological morbidity while waiting and immediately prior to the procedure. Health care costs during the waiting period as a consequence of arrhythmia were quantified. RESULTS: Mean scores for parameters of psychological morbidity worsened during the period of waiting and improved after the procedure. Predictors of adverse effects within the cohort varied according to the time point assessed for each of the measures of psychological morbidity. A conservative estimate of the health care cost incurred while waiting exceeds £ 181 per patient. CONCLUSIONS: Waiting for radiofrequency ablation appears to be associated with adverse psychological effects and health care costs. These results may support strategies to reduce waiting times and prioritize resource allocation.

[Alprazolam use improves psychological status and reduces hospitalization costs in patients with paroxysmal supraventricular tachycardia underwent radiofrequency catheter ablation].

OBJECTIVE: To evaluate the effect of alprazolam use on psychological status and hospitalization cost in patient with paroxysmal supraventricular tachycardia underwent electrophysiology studies or radiofrequency catheter ablation. METHODS: In this prospective, randomized, double-blind, placebo-controlled study, 142 inpatients [77 males, mean age (43.1 +/- 14.5) years] were randomly assigned to receive alprazolam (0.4 mg qd at 10PM for 3 days, n = 72) or placebo (n = 70) 3 days before scheduled electrophysiology studies or radiofrequency catheter ablation. All patients were examined by the Chinese version of Symptom Checklist-90 (SCL-90) at 24 hours before the procedure. RESULTS: Compared with the placebo group, the scores of somatization (1.38 +/- 0.40 vs. 1.65 +/- 0.56, P < 0.01), anxiety (1.50 +/- 0.39 vs. 1.69 +/- 0.50, P < 0.05), phobic anxiety (1.24 +/- 0.36 vs. 1.47 +/- 0.57, P < 0.01), psychotism constructs (1.24 +/- 0.34 vs. 1.35 +/- 0.30, P < 0.05) and global severity index (1.36 +/- 0.35 vs. 1.49 +/- 0.37, P < 0.05) were significantly decreased in alprazolam group. The hospitalization costs were also significantly lower in alprazolam group (32 498 +/- 1170) yuan compared to placebo group (32 947 +/- 1096) yuan, P < 0.05. CONCLUSION: The alprazolam use before electrophysiology studies and radiofrequency catheter ablation can improve the patients' psychological status and reduce the hospitalization costs.

Quality of life and cost for patients with premature ventricular contractions by radiofrequency catheter ablation.

OBJECTIVE: To evaluate the quality of life (QoL), health-care resource utilization, and cost for the patients with premature ventricular contractions (PVCs) by radiofrequency catheter ablation (RFCA). METHODS: RFCA was performed in 58 patients with symptomatic PVCs that were refractory/easy to medication. A 24-hour ambulatory electrocardiographic monitoring, QoL, health-care resources utilization, and cost were assessed at a screening visit and 3 and 12 months after RFCA. RESULTS: RFCA was successfully performed in 56 patients (96.6%). This resulted in a significant improvement in the QoL at 3 and 12 months after the procedure. There were no major complications related to the procedure. Nine patients (15.5%) had residual arrhythmia. Seven of them underwent repeated ablation with successful results. It also improved the QoL and reduced health-care resource utilization and cost. CONCLUSIONS: RFCA is a safe and effective treatment for PVCs, and it is a viable alternative to drugs in the presence of disabling symptoms.

Endometrial balloon ablation under local analgesia and intravenous sedation.

We report a series of women (n = 16) with menorrhagia undergoing endometrial balloon ablation under local analgesia with light sedation. Ten women had significant, coexistent medical problems. The median duration of the procedure was 8.6 minutes (range 8.47-9.5 minutes). Postoperative assessment included pain scores assessed by linear analogue scale; requirement for opiate analgesia; length of postoperative stay and patient satisfaction with the procedure. The minimum postoperative follow-up was 6 months. The procedure was well-tolerated and in 80% of cases either no postoperative analgesia or simple analgesia only was required. Two women were admitted overnight, 1 for social reasons and the other for pain control. Three women ages 44, 54 and 55 years were amenorrhoeic at 6 months; 8 women were still menstruating but satisfied with the outcome and 5 women are seeking further treatment for menorrhagia. While the longer-term efficacy of the procedure remains to be established these results indicate that endometrial balloon ablation under local analgesia and light sedation, a simple and acceptable technique, may be a suitable alternative to more difficult procedures such as rollerball ablation. This is most likely to be the case in appropriately selected women who are willing to accept a reduction in menstrual flow rather than amenorrhoea as the treatment outcome. The main disadvantage of balloon ablation is the cost of the disposable balloons and the need for a dedicated electrosurgical unit.

The cost-effectiveness of preference-based treatment allocation: the case of hysterectomy versus endometrial resection in the treatment of menorrhagia.

Typically, economic evaluation compares the costs and benefits of two or more interventions and seeks to identify the single superior option on the basis of relative cost-effectiveness. It is then anticipated that all patients will receive the more or most cost-effective option. This 'all or nothing' approach can be departed from when sub-groups of patient exist, defined on the basis of clinical or demographic characteristics which are considered to influence benefit, for whom an option is cost-effective whilst not being so for the population of patients as a whole. However, patients' preferences concerning the different process characteristics and outcomes of an intervention will also influence the benefit they derive from health care. This paper explores the concept of preference-based sub-group analysis in economic evaluation to assess the potential cost-effectiveness of using patients' preferences to determine treatment allocation. The clinical example used to explore these methods is the comparison of abdominal hysterectomy (AH) and transcervical resection of the endometrial (TCRE) for the treatment of menorrhagia.

Endometrial ablation.

Endometrial ablation is associated with a shorter operative time, fewer complications, less use of analgesics, a shorter convalescence and a quicker time to return to work than hysterectomy in the treatment of menorrhagia. Endometrial resection costs the health service provider less money than hysterectomy; however, women randomized to hysterectomy have reported slightly higher rates of satisfaction than those randomized to endometrial resection.
