Alternative Calculations of Individual Patient Time in Therapeutic Range While Taking Warfarin: Results From the ROCKET AF Trial Arrhythmia and Electrophysiology

Conclusions TTR, the standard measure of control of warfarin anticoagulation, depends on imputing daily INR values for the vast majority of follow-up days. Our TTR calculation method may better reflect the impact of warfarin dose changes than the Rosendaal approach. In the ROCKET AF trial, this dose change–based approach led to a modest increase in overall mean iTTR but did not materially affect the large inter-regional differences previously reported.

This study adopts a randomized double-blind, single-simulated, placebo-controlled research method. Participants were randomly assigned in a 1:1 ratio through a centrally controlled, computer-generated, simple randomization schedule. Participants would take the medicine for 1 month, and the curative effect would be evaluated. Subsequently, the participants would not take TCM and only receive western medicine treatment. They would be followed up for another 8 weeks, and a clinical evaluation would be conducted. The secondary outcomes include echocardiography, Hamilton Anxiety Scale, Hamilton Depression Scale, rate of increas...

ConclusionNOAF is a common occurrence in critically ill patients with sepsis, and its incidence rises with increasing severity of disease. Our Meta-analysis suggests that it is independently associated with poor outcome. In view of these findings there is a need for better quality observational studies, because reliable identification of patients with sepsis who are prone for the development of AF may allow for early pharmacological interventions to prevent this complication.

ConclusionThe current study found that low ejection fraction, dilated left atrium, hypertension, smoking, old age, male gender, prolonged bypass time, prolonged cross clamping time, renal impairment, previous myocardial infarction, ungrafted dominant right coronary artery, low temperatures on bypass, early ischemic changes postoperative, hypokalemia, use of adrenaline and nor adrenaline, all of these factors were a significant predictors for development of atrial fibrillation after cardiac surgery.

ConclusionThere are a wide range of significant epidemiological, clinical, and operative predictors for the development of post-CABG AF including older age, female gender, large LA diameter, higher CHA2DS2-VASc score, valve replacement and postoperative inotropic support. Nevertheless, further large-scale studies are still needed to confirm our findings.

Atrial fibrillation (AF) is the most common cardiac arrhythmia worldwide with an increasing risk of heart failure, stroke, and thromboembolic events. Currently distinct pathophysiological mechanisms during AF development and valuable biomarkers for AF management remain unknown.

Rev Cardiovasc Med. 2021 Sep 24;22(3):635-648. doi: 10.31083/j.rcm2203074.ABSTRACTAtrial fibrillation (AF) represents the most prevalent supraventricular arrhythmia in adults population and up to 15% of AF patients undergo percutaneous coronary intervention (PCI) for coronary artery disease (CAD) during their life. While oral anticoagulants (OACs) exert a protective effect in the setting of stroke prevention and systemic embolization in AF patients, patients undergoing PCI are recommended to receive dual antiplatelet therapy (DAPT) to reduce the risk of cardiovascular death, recurrent myocardial infarction and stent thromb...
