Major Outcomes in Atrial Fibrillation Patients with One Risk Factor: Impact of Time in Therapeutic Range

BACKGROUND: The benefits and harms of oral anticoagulation (OAC) therapy in patients with only one stroke risk factor (i.e. CHA2DS2-VASc= 1 in males, or 2 in females) has been subject of debate. METHODS: We analysed all patients with only one stroke risk factor from the merged datasets of SPORTIF III and V trials. Anticoagulation control was defined according to time in therapeutic range (TTR). RESULTS: Of the original trial cohort, 1,097 patients had only one stroke risk factor. Stroke/systemic thromboembolic event had an incidence of 0.9 per 100 patient-years, with an incidence of 1.6 per 100 patient-years for all-cause death and 2.3%/patient-years for the composite outcome of stroke/systemic thromboembolic event/all-cause death. There were no significant differences in the risk for stroke/systemic thromboembolic event between sexes, nor between the different stroke risk factors amongst these atrial fibrillation patients with only one stroke risk factor. Cox regression analysis in patients treated with warfarin only found TTR to be inversely associated with stroke/systemic thromboembolic event (p=0.034) and all-cause death (p=0.015). Chronic heart failure was significantly associated with the outcome of all-cause death (p=0.0019) and the composite outcome of stroke/systemic thromboembolic event/all-cause death (p=0.021). There was a significant inverse linear association between TTR and the cumulative risk for both stroke/systemic thromboembolic event and all-cause death (both p<0.001). CONCLUSIONS: In atrial fibrillation patients with only one additional stroke risk factor (i.e. CHA2DS2-VASc= 1 in males or 2 in females), rates of major adverse events (stroke/systemic thromboembolic event, mortality) were high, despite anticoagulation. TTR in warfarin-treated patients was inversely associated with the occurrence of both stroke/systemic thromboembolic event and all-cause death

Compliance of atrial fibrillation treatment with the ABC pathway in patients with concomitant diabetes mellitus in the Middle East based on the Gulf SAFE registry

Introduction Atrial fibrillation (AF) and diabetes mellitus (DM) constitute a heavy burden on healthcare expenditure due to their negative impact on clinical outcomes in the Middle East. The Atrial fibrillation Better Care (ABC) pathway provides a simple strategy of integrated approach of AF management: A—Avoid stroke; B—Better symptom control; C—Cardiovascular comorbidity risk management. Aims Evaluation of the AF treatment compliance to ABC pathway in DM patients in the Middle East. Assessment of the impact of ABC pathway adherence on all‐cause mortality and the composite outcome of stroke/systemic embolism, all‐cause death and cardiovascular hospitalisations. Methods From 2043 patients in the Gulf SAFE registry, 603 patients (mean age 63; 48% male) with DM were included in an analysis of ABC pathway compliance: A—appropriate use of anticoagulation according to CHA2DS2‐VASc score; B—AF symptoms management according to the European Heart Rhythm Association (EHRA) scale; C—Optimised cardiovascular comorbidities management. Results 86 (14.3%) patients were treated in compliance with the ABC pathway. During 1‐year follow‐up, 207 composite outcome events and 87 deaths occurred. Mortality was significantly lower in the ABC group vs non‐ABC (5.8% vs 15.9%, P = .0014, respectively). On multivariate analysis, ABC compliance was associated with a lower risk of all‐cause death and the composite outcome after 6 months (OR 0.18; 95% CI: 0.42‐0.75 and OR 0.54; 95% Cl: 0.30‐1.00, respectively) and at 1 year (OR 0.30; 95% Cl: 0.11‐0.76 and OR 0.57; 95% Cl: 0.33‐0.97, respectively) vs the non‐ABC group. Conclusions Compliance with the ABC pathway care was independently associated with the reduced risk of all‐cause death and the composite outcome in DM patients with AF, highlighting the importance of an integrated approach to AF management

Stroke Prevention in Atrial Fibrillation: Where are We Now?

Atrial fibrillation is the commonest arrhythmia worldwide and is a growing problem. AF is responsible for 25% of all strokes, and these patients suffer greater mortality and disability. Warfarin has traditionally been the only successful therapy for stroke prevention, but its limitations have resulted in underutilisation. Major progress has been made in AF research, leading to improved management strategies. Better risk stratification permits identification of truly low-risk patients who do not require anticoagulation and we are able to simplify ourevaluation of a patient’s bleeding risk

OTIVM, MATERIALIDADE E PAISAGEM NAS VILLAE DO ALTO ALENTEJO PORTUGUÊS EM ÉPOCA ROMANA

A arquitectura das villae foi cuidadosamente pensada para permitir o máximo des- frute de uma vivência de gosto urbano e cosmopolita. A atenção dada à inserção da construção na paisagem, as soluções para harmonizar o espaço exterior criando atmosferas favoráveis, a contemplação para o exterior e a criação de espaços e am- bientes construídos que permitissem potenciar o otium e o convivium são discutidos neste trabalho, com exemplos de sítios no Alto Alentejo
