Young people, stroke and a hole in the heart (PFO)

(This post introduces my latest column on TheHeart.org | Medscape Cardiology. It’s about stroke in young people.)  *** We define stroke as the death of brain cells. The typical cause is a blocked blood vessel in the brain. Stroke usually occurs in older people who have established blood vessel disease. Stroke is bad; it may be the worst outcome in all of medicine. That’s because stroke can permanently remove basic functions of being human, things such as speech, thought, personality, movement, swallowing, and many others. Stroke is not supposed to happen in young people. But sometimes it does. And in some of these cases, the cause may be due to a hole in the heart or patent foramen ovale (PFO). This membrane of sorts can allow blood to flow across the right and left atrium. From AHA What experts think happens in PFO-related stroke is that a clot from the venous system (say, from prolonged sitting or some other reason) travels from the right atrium across the PFO into the left atrium. That’s bad because LA clot goes to the left ventricle and gets pumped out into the body to lodge somewhere. (Since it is a straight shot from heart to brain, clots in the heart usually lodge in the brain.) But get this: about one in four humans have a PFO. Please read that again. One in four. So it’s completely normal to have a PFO. I see this all the time when doing AF ablations. Sometimes the catheter goes right across the membrane without help from the needle. The ...

“We’re not as healthy as we should be.” That’s what Fitbit CEO and co-founder James Park said at Thursday’s TIME 100 Health Summit, where MSNBC anchor Stephanie Ruhle interviewed him about the company’s future in the health care space, the impact of wearables and just how active Fitbit’s 30 million active users really are. Ruhle talked with Park about Fitbit’s position as one of the first major wearables company to have gone public, one that led the charge in terms of mass market adoption but has lost ground to competitors offering more advanced wearable devices, as well as ...

Publication date: Available online 16 October 2019Source: Sensors and Actuators A: PhysicalAuthor(s): Ssu-Han Chen, Aron Michael, Chee Yee KwokAbstractThis paper presents the fabrication and characterization of a high performance piezoelectrically driven micro-lens actuator. The fabrication method involves controlling the residual stresses in the structure to predefine the initial deflection of the actuator, resulting in a larger actuation stroke. The residual stress control exploits the unique properties of ultra-high vacuum e-beam evaporated film to form thick tensile polysilicon as the actuator structural layer. This is...
