If you get an Apple Watch Hypertension Notification, then you are 5 TIMES MORE LIKELY to have hypertension than if you didn't use your watch (LR+ 5.4). This is moderately useful test information. You should definitely get your blood pressure tested.

In providing career guidance, mentoring and coaching to academics, aspects of loyalty and holding grudges (disloyalty) often come up. This has provided structure to some of these conversations.

Query sarcoid, normal #WhyCMR, so then should we do FDG-PET? Not much benefit.
In patients with suspected cardiac sarcoidosis, cardiac FDG-PET is recommended after a normal CMR if there is a high clinical suspicion. What are the data supporting this recommendation? #CardioSky #MedSky #Sarcoidosis
