Aims: The prevalence of atrial fibrillation (AF) is positively correlated with prior cardiovascular diseases (CVD) and CVD risk factors but is lower in Chinese than Europeans despite their higher burden of CVD. We examined the prevalence and prognosis of AF and other electrocardiogram (ECG) abnormalities in the China Kadoorie Biobank. Methods and results: A random sample of 25 239 adults (mean age 59.5 years, 62% women) had a 12-lead ECG recorded and interpreted using a Mortara VERITAS™ algorithm in 2013-14. Participants were followed up for 5 years for incident stroke, ischaemic heart disease, heart failure (HF), and all CVD, overall and by CHA2DS2-VASc scores, age, sex, and area. Overall, 1.2% had AF, 13.6% had left ventricular hypertrophy (LVH), and 28.1% had ischaemia (two-thirds of AF cases also had ischaemia or LVH). The prevalence of AF increased with age, prior CVD, and levels of CHA2DS2-VASc scores (0.5%, 1.3%, 2.1%, 2.9%, and 4.4% for scores <2, 2, 3, 4, and ≥5, respectively). Atrial fibrillation was associated with two-fold higher hazard ratios (HR) for CVD (2.15; 95% CI, 1.71-2.69) and stroke (1.88; 1.44-2.47) and a four-fold higher HR for HF (3.79; 2.21-6.49). The 5-year cumulative incidence of CVD was comparable for AF, prior CVD, and CHA2DS2-VASc scores ≥ 2 (36.7% vs. 36.2% vs. 37.7%, respectively) but was two-fold greater than for ischaemia (19.4%), LVH (18.0%), or normal ECG (14.1%), respectively. Conclusion: The findings highlight the importance of screening for AF together with estimation of CHA2DS2-VASc scores for prevention of CVD in Chinese adults. [ABSTRACT FROM AUTHOR]

Objectives: Bullying of trainee doctors has been shown to be associated with detrimental outcomes for both doctors and patients. However, there is limited evidence regarding the level of bullying of trainees within medical specialties.Methods: An annual survey of UK cardiology trainees was conducted through the British Junior Cardiologists' Association between 2017 and 2020 and asked questions about experiencing and witnessing bullying, and exposure to inappropriate language/behaviour in cardiology departments. Fisher's exact tests and univariable logistic regression models were used to describe associations between trainee characteristics, and reports of bullying and inappropriate language/behaviour.Results: Of 1358 trainees, bullying was reported by 152 (11%). Women had 55% higher odds of reporting being bullied (OR: 1.55 95% CI (1.08 to 2.21)). Non-UK medical school graduates were substantially more likely to be bullied (European Economic Area (EEA) OR: 2.22 (1.31 to 3.76), non-EEA/UK OR: 3.16 (2.13 to 4.68)) compared with those graduating from UK-based medical schools. Women were more likely than men to report sexist language (14% vs 4%, p<0.001). Non-UK medical school graduates were more likely to experience racist language (UK 1.5%, EEA 6%, other locations 7%, p=0.006). One-third of trainees (33%) reported at least one inappropriate behaviour with 8% reporting being shouted at or targeted with spontaneous anger. Consultants in cardiology (82%) and other specialties (70%) were most commonly implicated by those reporting bullying.Discussion: Bullying and inappropriate language are commonly experienced by cardiology trainees and disproportionately affect women and those who attended non-UK medical schools. Consultants both in cardiology and other specialties are the most commonly reported perpetrators. [ABSTRACT FROM AUTHOR]
