Multicenter Study Observational Study Pragmatic Clinical Trial
NOACs and atrial fibrillation: Incidence and predictors of left atrial thrombus in the real world.
Despite optimal oral anticoagulation with vitamin K antagonist, left atrial (LA) thrombus could be detected in the left appendage (LAA) in >2% of patients with atrial fibrillation (AF) and CHA2DS2-VASc score≥1 but few data are available for patients treated with non-vitamin K antagonist oral anticoagulants (NOACs). We evaluated the occurrence and predictors of LA thrombi by means of transesophageal echocardiography (TOE) in consecutive patients with non-valvular AF who received for at least 3weeks Apixaban, Dabigatran, or Rivaroxaban. ⋯ The incidence of LAA thrombus in a cohort of patients anticoagulated with NOACs is low but not negligible, in any case similar among the 3 drugs. Preprocedural TOE should be considered in patients with a CHA2DS2-VASc score>3.

Association between QRS duration on prehospital ECG and mortality in patients with suspected STEMI.
QRS duration has previously shown association with mortality in patients with acute myocardial infarction treated with thrombolytics, less is known in patients with suspected ST segment elevation myocardial infarction (STEMI) when assessing QRS duration on prehospital ECG. Thus, the objective was to investigate the prognostic effect of QRS duration on prehospital ECG and presence of classic left and right bundle branch block (LBBB/RBBB) for all-cause mortality in patients with suspected STEMI. ⋯ In patients with suspected STEMI, QRS prolongation, LBBB, and RBBB on prehospital ECG are associated with increased risk of death.

Short and long-term prognostic value of hyponatremia in heart failure with preserved ejection fraction versus reduced ejection fraction: An analysis of the Korean Acute Heart Failure registry.
Hyponatremia is a well-known risk factor for worse outcomes in heart failure (HF) patients. The impact of hyponatremia according to the ejection fraction (EF) is unclear. We evaluated the prognostic value of hyponatremia according to HF type. ⋯ Hyponatremia is independent of HF type. Hyponatremia is a significant risk factor for adverse in-hospital outcomes; however its long-term prognostic value is only limited to patients with HFrEF, but not for those with HFpEF.

Use of statins and adverse outcomes in patients with atrial fibrillation: An analysis from the EURObservational Research Programme Atrial Fibrillation (EORP-AF) general registry pilot phase.
Despite oral anticoagulation being highly effective in reducing stroke and thromboembolism, patients with atrial fibrillation (AF) still have a significant residual excess in mortality risk. Additional management strategies are needed to reduce the mortality risk seen in AF patients. ⋯ Statin use in AF patients was associated with improved outcomes, with an independent association with a lower risk of all-cause death at 1-year follow-up.
