To evaluate whether right ventriculo-arterial coupling obtained by the estimation of the two-dimensional right ventricular (RV) longitudinal strain and of the pulmonary arterial systolic pressure (PASP) could improve prognostic stratification of chronic heart failure (CHF) outpatients. ⋯ Indexing RV function, assessed by speckle-tracking analysis, with an estimation of pulmonary systolic arterial pressure provides a parameter of ventricular arterial coupling that is independently associated with an increased risk of mortality.

Patients with atrial fibrillation or flutter (AFF) are at increased risk of ischemic stroke, but their risk of other thromboembolic events remains less clear. ⋯ AFF was a risk factor for all arterial and venous outcomes during the first year of follow-up, but only for peripheral embolism, ischemic stroke, and hemorrhagic stroke thereafter.

Randomized Controlled Trial
Effect of CPAP on diastolic function in coronary artery disease patients with nonsleepy obstructive sleep apnea: A randomized controlled trial.
Obstructive sleep apnea (OSA) has been associated with worse diastolic function in patients with coronary artery disease (CAD). This analysis determined whether continuous positive airway pressure (CPAP) treatment would improve diastolic function in CAD patients with nonsleepy OSA. ⋯ CPAP did not improve diastolic dysfunction in CAD patients with nonsleepy OSA. However, good CPAP adherence was significantly associated with an increase in diastolic relaxation velocity after one year.
