Aims: To investigate differences in clinical presentation and prognosis between East Asians and Europeans with atrial fibrillation (AF) who have experienced major bleeding (MB).

Methods And Results: We analysed two prospective registries enrolling AF patients from the Asian-Pacific Heart Rhythm Society (APHRS) and EURObservational Research Programme (EORP). Ethnicity was inferred by enrolment country.

Background: Discontinuation of oral anticoagulants (OACs) in patients with atrial fibrillation (AF) at high risk of bleeding is commonly seen.

Objective: This study aimed to explore risk factors leading to OAC discontinuation and the impact on clinical events in patients with AF at high bleeding risk.

Methods: From the prospective, multicenter Global Registry on Long-Term Antithrombotic Treatment in Patients With Atrial Fibrillation study, we analyzed, by OAC discontinuation, all-cause death, cardiovascular (CV) death, major adverse CV events (MACEs), thromboembolism (TE), major bleeding, stroke, and myocardial infarction during follow-up.

Background: Clinical associations and prognosis of patients with symptom-controlled AF (scAF) remain poorly understood.

Methods: We analysed data from the Asian-Pacific Heart Rhythm Society and EURObservational Research Programme registries. Based on the European Heart Rhythm Association (EHRA) score, patients were classified as scAF (EHRA I or II) or symptomatic AF (EHRA III or IV).

Background: Older age increases the risk of thromboembolism (TE) and major bleeding in atrial fibrillation (AF) patients, but limited evidence exists regarding the older population (age ≥ 80) especially from different global regions. Data on benefits of oral anticoagulants in these very old individuals are also limited.

Methods: From the prospective, multicenter Global Registry on Long-Term Antithrombotic Treatment in Patients with Atrial Fibrillation registry, we analysed by age all-cause death, cardiovascular death, major adverse cardiovascular events (MACE), TE, major bleeding, stroke, and myocardial infarction (MI) over 3-years follow-up.

Aims: Whether the adoption of CHA2DS2-VA score, the sex-independent version of the CHA2DS2-VASc score is beneficial for stratifying risk of stroke in patients with atrial fibrillation (AF) remains controversial.

Methods And Results: Utilizing the data from the global, multicentre and prospective GLORIA-AF Registry Phase III, we compared the performances of CHA2DS2-VA and CHA2DS2-VASc scores in stratifying the risk of ischaemic stroke and thromboembolism (TE), and compared the risk of ischaemic stroke and TE, and the use of oral anticoagulants in male and female patients with AF. A total of 21 260 AF patients with available data were included in the analysis (mean age 70.

Renal function, assessed by creatinine clearance (CrCl), affects the efficacy and safety of oral anticoagulant (OAC) therapy in patients with atrial fibrillation (AF). To investigate the association between CrCl and the risk of clinical adverse events and compare the safety profiles of vitamin K antagonists (VKA) and non-vitamin K antagonist oral anticoagulants (NOAC). Patients with newly diagnosed AF (< 3 months before baseline visit) were collected from the prospective Global Registry on Long-Term Oral Anti-Thrombotic Treatment in Patients with Atrial Fibrillation (GLORIA-AF) registry Phase III.

Background: Patients with atrial fibrillation (AF) who suffered a previous stroke are at increased risk of recurrent thromboembolic events and other major outcomes. The impact of the number of stroke episodes on the natural history of patients with AF is still unclear.

Methods And Results: Using data from the international, multicenter, and prospective GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients With Atrial Fibrillation) Registry Phase III, we categorized patients with a recent diagnosis of non-valvular AF according to the number of previous strokes (either 0, 1, or ≥2 episodes).

Background: Hypertension (HTN) is the most important modifiable risk factor for the development of cardiovascular events (CVEs). Patients with axSpA are also associated with an increased risk of future CVE.

Objectives: To ascertain whether baseline early-stage HTN is a predictor of future CVE in addition to inflammation in patients with axial spondyloarthritis (axSpA).

Background: Macrolide maintenance therapy (MMT) has demonstrated notable efficacy in reducing exacerbation in patients with bronchiectasis, which is a major risk factor for cardiovascular events. However, a comprehensive assessment of the cardiovascular benefits and safety profile of MMT in this population is lacking.

Methods: This territory-wide cohort study analysed patients diagnosed with bronchiectasis in Hong Kong between 2001 and 2018.

Background: Anticoagulation therapy in patients with atrial fibrillation (AF) and concomitant cancer can be challenging due to the significantly increased risk of both embolism and bleeding. Moreover, the benefits and risks of vitamin K antagonists (VKA, eg. warfarin) versus non-vitamin K antagonist oral anticoagulants (NOACs) in such patients are less well understood.

Article Synopsis
  • A study explored the risk of thromboembolic events in patients with atrial fibrillation (AF) who were on oral anticoagulants (OACs) by analyzing different patient profiles.
  • Researchers used data from over 22,000 patients in the GLORIA-AF registry and identified five distinct patient profiles, including factors like age, obesity, and hypertension.
  • Among the profiles, "frailty" had the highest risk for thromboembolic events and death, while a profile classified as "young and obese" showed the lowest risk, highlighting the need for tailored risk assessment in AF patients.

Objective: To examine the independent effect of inflammatory burden and various treatments on the risk of incident major adverse cardiovascular events (MACE) in ankylosing spondylitis (AS) patients.

Methods: AS patients were retrospectively selected from a territory-wide database between 2006 and 2015, and were followed until the end of 2018. The primary outcome was the first occurrence of MACE.

Article Synopsis
  • * Data from over 14,000 AF patients were analyzed, revealing that after three years, there were significant rates of major cardiovascular events (MACE) and death among those on different treatment regimens.
  • * Results showed that patients using combination therapy (beta-blockers and digoxin) had a higher risk of MACE and all-cause death compared to those using only beta-blockers.

Objectives: Cardiovascular event (CVE) risk in rheumatoid arthritis (RA) was increased by glucocorticoids (GC) use. Whether there is a threshold dose and duration of GC use beyond which will increase CVE rate remains controversial. We studied the time-varying effect of GC and its dose on the risk of incident major adverse cardiovascular events (MACE) in patients with RA.

Objective: To examine whether Disease Activity in Psoriatic Arthritis (DAPSA) reflecting the inflammatory component of psoriatic arthritis (PsA) can predict cardiovascular (CV) events independent of traditional CV risk factors and subclinical carotid atherosclerosis.

Methods: A cohort analysis was performed in patients with PsA who had been followed since 2006. The outcome of interest was first CV event.
