Rivaroxaban Monotherapy for Atrial Fibrillation in Coronary Artery Disease Patients
For patients with atrial fibrillation and stable coronary artery disease, rivaroxaban monotherapy was superior to dual therapy for preventing thrombotic and bleeding events and was associated with a lower mortality.

The Value of Stress Testing in Patients with Known Coronary Artery Disease
A comparison of adenosine stress singe photon emission CT, PET, and MRI in stable patients with known coronary artery disease (CAD) showed PET to be more sensitive for detecting invasive fractional flow reserve-identified ischemic lesions. However, the sensitivity was disappointing; thus, patients with known CAD and new symptoms should be referred directly to invasive coronary angiography.

Examining the Mortality Risk of Physical Activity in Parkinson’s Disease
In individuals with Parkinson’s disease (PD), physical activity (PA) at all intensities was associated with a lower all-cause mortality rate, with the greatest reduction seen in individuals who maintained PA before and after PD diagnosis.

The Effects of Yoga for Patients with Vasovagal Syncope
Randomization to yoga in addition to standard care to treat vasovagal syncope led to better outcomes than standard care alone, with reductions in syncopal and presyncopal events and improvement in quality of life scores at one year.

Examining the Relationship Between Sleep in Middle Age and Dementia Development
This long-term study revealed people who reported sleeping an average of seven hours or less nightly at age 50 years and 60 years were 30% more likely to develop dementia than their counterparts who reported sleeping seven hours or more.
