Anxiety, depression, and low-grade inflammation were the factors that predicted both arrhythmia-related symptoms and HRQoL in patients with AF. Obesity was the most significant predictor of patient general physical status. These factors need to be addressed in patients with AF to improve management of their disease. Intensive risk factor modification can be of great importance. (Reasons for Variations in Health Related Quality of Life and Symptom Burden in Patients With Atrial Fibrillation [SMURF]; NCT01553045).
Routine use of supplemental oxygen in normoxemic patients with STEMI undergoing primary PCI did not significantly affect 1-year all-cause death, rehospitalization with MI, cardiogenic shock, or stent thrombosis.
Background The primary goal of radiofrequency ablation (RFA) of atrial fibrillation (AF) is to improve symptoms and health‐related quality of life (HRQoL). However, most studies have focused on predictors of AF recurrence rather than on predictors of improvement in symptoms and HRQoL. Hypothesis We sought to explore predictors of improvement in arrhythmia‐specific symptoms and HRQoL after RFA of AF, and to evaluate the effects on symptoms, HRQoL, anxiety, and depression. Methods We studied 192 patients undergoing their first RFA of AF. The Medical Outcomes Study 36‐Item Short‐Form Health Survey (SF‐36), arrhythmia‐specific questionnaire in tachycardia and arrhythmia (ASTA), and hospital anxiety and depression scale (HADS) questionnaires were filled out at baseline, at 4 months, and at a 1‐year follow‐up. Results All questionnaire scale scores improved significantly over time. In the ASTA symptom scale score, female gender and > 10 AF episodes the month before RFA were significant positive predictors of improvement, while diabetes and AF recurrence within 12 months after RFA were significant negative predictors (R2 = 0.18; P < 0.001). In the ASTA HRQoL scale score, the presence of heart failure and > 10 AF episodes the month before RFA were significant positive predictors of improvement, while diabetes, maximum left atrial volume and AF recurrence were significant negative predictors (R2 = 0.20; P < 0.001). Conclusion Left atrial volume, gender, diabetes, heart failure, the frequency of AF attacks prior to RFA, and recurrence of AF after RFA were significant factors affecting improvement in symptoms and HRQoL after RFA of AF. Future studies are warranted to confirm these findings.
Background Information on alcohol consumption in patients undergoing radiofrequency ablation (RFA) of atrial fibrillation (AF) is often limited by the reliance on self-reports. The aim of this study was to describe the long-term alcohol consumption, measured as ethyl glucuronide in hair (hEtG), in patients undergoing RFA due to AF, and to examine potential associations with cardiac biomarkers, left atrial size and re-ablation within one year after the initial RFA. Methods The amount of hEtG was measured in patients referred for RFA, and a cut-off of 7 pg/mg was used. N-terminal pro B-type natriuretic peptide (NT-proBNP) and the mid-regional fragment of pro atrial natriuretic peptide (MR-proANP) were examined and maximum left atrium volume index (LAVI) was measured. The number of re-ablations was examined up to one year after the initial RFA. Analyses were stratified by gender, and adjusted for age, systolic blood pressure, body mass index, presence of heart failure and heart rhythm for analyses regarding NT-proBNP, MR-proANP and LAVI and heart rhythm being replaced by type of AF for analyses regarding re-ablation. Results In total, 192 patients were included in the study. Median (25th– 75 th percentile) NT-proBNP in men with hEtG ≥ 7 vs. < 7 pg/mg was 250 (96–695) vs. 130 (49–346) pg/ml (p = 0.010), and in women it was 230 (125–480) vs. 230 (125–910) pg/ml (p = 0.810). Median MR-proANP in men with hEtG ≥ 7 vs. < 7 pg/mg was 142 (100–224) vs. 117 (83–179) pmol/l (p = 0.120) and in women it was 139 (112–206) vs. 153 (93–249) pmol/l (p = 0.965). The median of maximum LAVI was 30.1 (26.7–33.9) vs. 25.8 (21.4–32.0) ml/m 2 (p = 0.017) in men, and 25.0 (18.9–29.6) vs. 25.7 (21.7–34.6) ml/m 2 (p = 0.438) in women, with hEtG ≥ 7 vs. < 7 pg/ml, respectively. Adjusted analyses showed similar results, except for MR-proANP turning out significant in men with hEtG ≥ 7 vs. < 7 pg/mg (p = 0.047). The odds ratio of having a re-ablation was 3.5 (95% CI 1.3–9.6, p = 0.017) in men with hEtG ≥ 7 vs. < 7 pg/mg, while there was no significant difference in women. Conclusions In male patients with AF and hEtG ≥ 7 pg/mg, NT-proBNP and MR-proANP were higher, LA volumes larger, and there was a higher rate of re-ablations, as compared to men with hEtG < 7 pg/mg. This implies that men with an alcohol consumption corresponding to an hEtG-value ≥ 7, have a higher risk for LA remodelling that could potentially lead to a deterioration of the AF situation.
