Alcohol and new onset atrial fibrillation: a case-control study of a current series.

Abstract Background The impact of new-onset postoperative atrial fibrillation (POAF) on long-term outcomes of patients after non-cardiac surgery remains controversial. Here we report the 3-year follow-up of a previous case-control study to determine the relationship between new-onset POAF and long-term outcomes in patients after non-cardiac surgery. Methods In a previous case-control study, 213 patients who were admitted to the intensive care unit (ICU) after non-cardiac surgery were included; of them 71 were in the POAF group and 142 the control group. A telephone interview was performed with patients or their family members at 3 years after surgery. The primary endpoint was the incidence of major adverse cardiovascular events (MACEs) within 3 years, including cardiovascular death, non-fatal cardiac arrest, acute myocardial infarction, congestive heart failure, and ischemic stroke. A logistic regression model was established to assess the association between the occurrence of new-onset POAF and the development of 3-year MACEs. Results 202 patients completed the 3-year follow-up and were included in the analysis; of them 68 were in the POAF group and 134 were in the control group. The incidence of 3-year MACEs was higher in the POAF group than in the control group (64.7% [44/68] vs. 23.1% [31/134], p<0.001). After correction for confounding factors, new-onset POAF was independently associated with an increased risk of 3-year MACEs (odds ratio 5.448, 95% confidence interval 2.202-13.481, p<0.001). Conclusions For adult patients admitted to the ICU after non-cardiac surgery, new-onset POAF was an independent risk factor for the development of MACEs within 3 years.

Abstract Background The association between anxiety and atrial fibrillation (AF) remains unclear. Moreover, this association has rarely been studied in Chinese individuals aged 60 years or older. This study investigated the association between anxiety and AF in a community-based case-control study of older adult residents in urban China. Methods The cases and controls were from a community-based study conducted in the Jingansi community in Shanghai, China, between January 2010 and December 2012. A total of 3622 residents aged 60 years or older without severe vision, hearing, or speaking impairments were eligible to participate in the physical examinations and questionnaire survey. AF was assessed based on a previous physician’s diagnosis, electrocardiogram, ambulatory electrocardiogram, or echocardiogram. Anxiety was evaluated using the Zung Self-Rating Anxiety Scale (ZSAS). Using the AF group as a reference, the control group consisted of randomly selected age- and sex-matched individuals in a 1:5 ratio (case:control = 1:5). The association between anxiety and AF in the AF group and the multifactor-matched control group was explored using logistic regression. Results In the AF and control groups, after adjusting for a history of coronary heart disease, valvular heart disease, hypertension, stroke, hyperlipidemia, and diabetes, as well as depression score, ZSAS scores (odds ratio 1.07; 95% confidence interval 1.02–1.12; p = 0.003), and anxiety symptoms (odds ratio 3.94; 95% confidence interval 1.06–14.70; p = 0.041) were associated with AF. Conclusions Anxiety symptoms were associated with AF in a Chinese older population. This suggests that older adults who have anxiety symptoms may need psychological intervention or treatment in daily life and care.

Background: Previous studies suggested that Parkinson's Disease (PD) patients could have an increased risk of atrial fibrillation. However, data supporting this association is not robust. We aimed to compare the potential risk of atrial fibrillation associated with PD in an age and gender matched case-control study, comparing the p-wave indexes from electrocardiograms and clinical risk scores among groups.Methods: A cross-sectional case-control study was performed. All subjects included in the analysis were clinically evaluated and subjected to a 12-lead electrocardiogram. Two blinded independent raters measured the p-wave duration. Subjects were classified as having normal P-wave duration (<120 ms), partial IAB (P-wave duration ≥ 120 ms, positive in inferior leads), and advanced IAB (p-wave duration ≥ 120 ms with biphasic morphology in inferior leads). Atrial fibrillation risk scores (CHARGE-AF, HATCH, and HAVOC) were calculated.Results: From 194 potential participants, three were excluded from the control group due to a previous diagnosis of atrial fibrillation. Comparing the PD patients (n = 97) with controls (n = 95), there were no statistically significant differences regarding the mean p-wave duration (121 ms vs. 122 ms, p = 0.64) and proportion of advanced interatrial block (OR = 1.4, 95%CI = 0.37–5.80, p = 0.58). All patients had a low or medium risk of developing atrial fibrillation based on the clinical scores. There were no differences between the PD patients and controls regarding the mean values of CHARGE-AF, HATCH, and HAVOC.Conclusions: Our results do not support the hypothesis that PD patients have an increased risk of atrial fibrillation based on the p-wave predictors and atrial fibrillation clinical scores.
