Patient-Reported Treatment Satisfaction with Rivaroxaban for Stroke Prevention in Atrial Fibrillation. A French Observational Study, the SAFARI Study.

For antithrombotic treatments, Patient Reported Outcomes (PRO) and patient satisfaction with treatment are essential data for physicians because of the strong relationship between patient satisfaction and adherence to treatment. The impact of rivaroxaban on patient satisfaction and quality of life was not sufficiently documented in phase III studies. There is a need for further data in this field especially in real life conditions.The SAFARI study is composed of patients with non-valvular atrial fibrillation (AF), previously treated with vitamin K antagonist (VKA) and switched to rivaroxaban. Patient satisfaction with anticoagulant therapy was measured by the Anti-Clot Treatment Scale (ACTS), a validated 15-item patient-reported scale including a 12-item ACTS Burdens scale and a 3-item ACTS Benefits scale. Satisfaction of medication was compared between baseline and 1, 3 and 6 months.Study population was composed of 405 patients. Mean age was 74.8 (standard deviation = 9.0) years and 63.0% were male. Mean CHA2DS2-VASc score was 3.4 (1.5) and mean HAS-BLED score was 2.9 (1.0). After 3 months of treatment with rivaroxaban, patient satisfaction improved compared with VKA: mean ACTS burdens scores significantly increased by 8.3 (8.9) points (p<0.0001) and ACTS benefits scale by 0.4 (2.9) (p<0.001). Compared with baseline, the improvement in ACTS burdens and benefits became apparent at 1 month (46.5 vs. 53.6 p<0.001 and 10.4 vs. 10.7, p<0.05 respectively) and persisted at 6 months (46.5 vs. 54.76 p<0.001 and 10.4 vs. 10.8 p = 0.02 respectively). Rivaroxaban persistence was 88.7% at 6 months.SAFARI data support a good risk-benefit balance for rivaroxaban, with a good safety profile and encourage PRO design studies. The switch from VKA to rivaroxaban improved patient satisfaction at 1, 3 and 6 months after rivaroxaban initiation among patients with AF, particularly in reducing patient-reported anticoagulation burden

Association Between Occupational, Sport, and Leisure Related Physical Activity and Baroreflex Sensitivity The Paris Prospective Study III

Physical activity (PA) is a preventative behavior for noncommunicable disease. However, little consideration is given as to whether different domains of PA have differing associations with health outcomes. We sought to determine the association between occupational, sport, leisure, and total PA with baroreflex sensitivity (BRS), distinguishing between neural (nBRS) and mechanical (mBRS) BRS. In a cross-sectional analysis of 8649 adults aged 50 to 75 years, resting nBRS (estimated by low-frequency gain, from carotid distension rate and heart rate) and mBRS (carotid stiffness) were measured by high-precision carotid echo-tracking. PA was self-reported using the validated Baecke questionnaire. The associations between PA and nBRS and mBRS were quantified using multivariate linear regression analysis, separately in the working and nonworking population. In working adults (n=5039), occupational PA was associated with worse nBRS (unstandardized β=-0.02; [95% CI, -0.04 to -0.003]; P=0.022) whereas sport PA was associated with better nBRS (β=0.04; [95% CI, 0.02-0.07]; P=0.003) and mBRS (β=-0.05; [95% CI, -0.09 to -0.00001]; P=0.049). Neither leisure PA nor total PA was associated with nBRS or mBRS. In nonworking adults (n=3610), sport PA and total PA were associated with better mBRS (β=-0.08; [95% CI, -0.15 to 0.02]; P=0.012 and β=-0.05; [95% CI, -0.10 to 0.009]; P=0.018) but not nBRS. These findings suggest differential associations between domains of PA and BRS and may provide insights into the mechanisms underlying the association between occupational PA and cardiovascular disease

The Multifaceted Interplay between Atrial Fibrillation and Myocardial Infarction: A Review

International audienceThis review was conducted to emphasize the complex interplay between atrial fibrillation (AF) and myocardial infraction (MI). In type 1 (T1) MI, AF is frequent and associated with excess mortality. Moreover, AF after hospital discharge for T1MI is not rare, suggesting the need to improve AF screening and to develop therapeutic strategies for AF recurrence. Additionally, AF is a common trigger for type 2 MI (T2MI), and recent data have shown that tachyarrhythmia or bradyarrhythmia could be a causal factor in, respectively, 13–47% or 2–7% of T2MI. In addition, AF is involved in T2MI pathogenesis as a result of severe anemia related to anticoagulants. AF is also an underestimated and frequent cause of coronary artery embolism (CE), as a situation at risk of myocardial infarction with non-obstructive coronary arteries. AF-causing CE is difficult to diagnose and requires specific management. Moreover, patients with both AF and chronic coronary syndromes represent a therapeutic challenge because the treatment of AF include anticoagulation, depending on the embolic risk, and ischemic heart disease management paradoxically includes antiplatelet therapy

Carbon monoxide and prognosis in smokers hospitalised with acute cardiac events: a multicentre, prospective cohort studyResearch in context

Summary: Background: Smoking cigarettes produces carbon monoxide (CO), which can reduce the oxygen-carrying capacity of the blood. We aimed to determine whether elevated expiratory CO levels would be associated with a worse prognosis in smokers presenting with acute cardiac events. Methods: From 7 to 22 April 2021, expiratory CO levels were measured in a prospective registry including all consecutive patients admitted for acute cardiac event in 39 centres throughout France. The primary outcome was 1-year all-cause death. Initial in-hospital major adverse cardiac events (MAE; death, resuscitated cardiac arrest and cardiogenic shock) were also analysed. The study was registered at ClinicalTrials.gov (NCT05063097). Findings: Among 1379 patients (63 ± 15 years, 70% men), 368 (27%) were active smokers. Expiratory CO levels were significantly raised in active smokers compared to non-smokers. A CO level >11 parts per million (ppm) found in 94 (25.5%) smokers was associated with a significant increase in death (14.9% for CO > 11 ppm vs. 2.9% for CO ≤ 11 ppm; p  11 ppm was associated with a significant increase in MAE in smokers during initial hospitalisation after adjustment for comorbidities (odds ratio [OR] 15.75, 95% CI [5.56–44.60]) or parameters of in-hospital severity (OR 10.67, 95% CI [4.06–28.04]). In the overall population, CO > 11 ppm but not smoking was associated with an increased rate of all-cause death (HR 4.03, 95% CI [2.33–6.98] and 1.66 [0.96–2.85] respectively). Interpretation: Elevated CO level is independently associated with a 6-fold increase in 1-year death and 10-fold in-hospital MAE in smokers hospitalized for acute cardiac events.
