There was no statistically significant different in the occurrence of heart failure or myocardial ischemia between the two treatment groups order luvox 50mg line. In the study comparing AVN ablation plus VVIR pacing versus rate-control medication generic luvox 50 mg, there was no significant difference in all-cause mortality or cardiovascular events at 12 months. There were two deaths in the ablation arm and one death in the medication arm (p=0. We rated the findings of no significant difference for all-cause and cardiovascular mortality as having a low strength of evidence. One Procedure Versus Another In a study comparing AVN ablation plus biventricular pacing versus AVN ablation plus RV pacing, total mortality was reported over a 3-year period. This study found no statistically significant difference in mortality for these two treatment groups, with 8 and 18 percent deaths (p=0. In the study comparing VVIR pacing plus His bundle ablation versus VVIR pacing plus rate-control 158 medications, exercise capacity was tested using a symptom-limited treadmill exercise test. In this study, both groups had a significant improvement in exercise duration of approximately 20 and 40 percent, respectively, but the improvements were not statistically significantly different between treatment groups (full statistical results not reported in paper). In the study comparing 160 AVN ablation plus VVIR pacing versus rate-control medication, all patients also underwent treadmill exercise tests. At 12 months, neither group had any significant improvement in exercise duration, and exercise duration at baseline and at 12 months did not differ significantly between groups. The maximum heart rate achieved with exercise was significantly lower, however, in patients receiving ablation compared with those receiving medication (112±17 vs. One Procedure Versus Another One study compared AVN ablation plus biventricular pacing versus AVN ablation plus RV 162 pacing and evaluated exercise capacity based on 6-minute walk test distance. This study found improvement in both arms from preablation measures to 6 months postprocedure. However, the improvement in walking distance was significantly greater among those in the biventricular pacing group at 82. Quality of Life Procedures Versus Drugs Two studies described outcomes related to quality of life at 6 or 12 months, but they used 158,160 different measurement tools and differed in their results. In the study comparing VVIR 158 pacing plus His bundle ablation versus VVIR pacing plus rate-control medications, the burden of cardiac symptoms was measured using a modified Karolinska Questionnaire, which has been 164 validated for patients with pacemakers. This study also administered the Nottingham Health 165,166 Profile to measure general quality of life, a tool previously validated in cardiac patients. Patients in both treatment arms had significant improvements over the 12-month followup period both in their burden of cardiac symptoms and in their general quality of life; however, there was no statistically significant difference in these improvements by treatment arm (full statistical results not provided in the paper for either measure). Based on two of these three measures, there was no statistically significant difference in the change in quality of life, which was minimal, between treatment groups at 12 months. However, 36 based on the CAST measure, those patients who received AVN ablation plus VVIR pacing had significantly improved ratings of their quality of life compared with those on medications, with a 160 relative risk reduction in symptoms of 18 percent (p=0. There were no statistically significant differences between groups at 5 years in the AQoL measures (no p-value given) or in SIP scores (p=0. Overall life satisfaction scores and psychosocial scores on the CAST questionnaire also did not differ between treatment groups (p>0. The strength of evidence was rated as insufficient to determine the impact of the interventions on quality of life. One Procedure Versus Another In the study comparing AVN ablation plus biventricular pacing versus AVN ablation plus 162 RV pacing, there was reportedly no difference in quality of life at 6 months between treatment arms as measured by the SF-36 Health Status Scale (detailed results were not provided; insufficient strength of evidence). Adverse Events Procedures Versus Drugs 160 Three studies described adverse events, with one study including a second publication 163 describing long-term outcomes of the interventions. In the two studies using antiarrhythmic 157,159 drugs, two patients reported adverse events, including one episode of torsade-de-points in a 159 patient receiving sotalol and one case of heart failure in a patient receiving propafenone. No 157 adverse reactions were reported by patients receiving amiodarone. One study using rate- 160 control drugs reported adverse events, finding three hematomas in the ablation arm, as well as one pulmonary embolus. During long-term followup of this study, two patients who received ablation plus pacing developed heart failure, one patient who received ablation plus pacing developed failure to capture related to malfunction of their pacemaker, and one patient in the medication arm experienced prolonged pauses with their AF and required pacemaker 163 placement. One Procedure Versus Another In the study comparing AVN ablation plus biventricular pacing versus AVN ablation plus RV pacing, overall numbers of complications were reported for a 3-year period and included adverse events related to pacemaker dysfunction, such as diaphragmatic stimulation, lead dislodgement, and oversensing, as well as adverse events related to pacemaker placement 162 including pneumothorax, hematoma, and infection. There was no significant difference in overall complication rates between treatment arms, with rates of 15 and 6 percent (p=0. This study found that the results of heart rate changes or exercise capacity by treatment group did not differ from the main 160 study for this subgroup. One Procedure Versus Another The study comparing AVN ablation plus biventricular pacing versus AVN ablation plus RV pacing also evaluated 6-month outcomes of subgroups of participants based on LVEF. This study found that among participants with an LVEF >45 percent (n=89), both treatment arms had improvements in 6-minute walk distance, and there was no significant difference between treatment groups in this improvement. However, among participants with an LVEF ≤45 percent (n=76), those participants receiving biventricular pacing had significantly greater improvements in their 6-minute walk distance compared with those receiving RV pacing, with improvements of 96. This study also compared outcomes for patients with different functional classes of heart failure based on New York Heart Association (NYHA) symptoms. Similar to the pattern observed for patients by LVEF, those with NYHA class I symptoms demonstrated similar improvements in 6-minute walk distance (p=0.
