Wearing a continuous positive airway pressure device helps heart failure patients with obstructive sleep apnea get a good night's rest

Wearing a continuous positive airway pressure (CPAP) device not only helps heart failure patients with obstructive sleep apnea get a good night's rest, it lowers blood pressure and heart rate well into the morning, apparently, by reducing sympathetic nervous system activity, according to a new study (PDF) in the June 21, 2005, issue of the Journal of the American College of Cardiology.

Cameras and MP3 players are fun, but the next wave of add-ons for cell phones and laptops may help users keep track of their health

A University of Florida engineer has built a working prototype for a small, portable system that can monitor a person’s breathing and heart rate automatically via wireless signal, with no need for cords or plugs. The goal is to make it easy for people to check their own vital signs, and then transmit them in real time to medical personnel through a cell phone or Internet connection, all with little more than a press of a button.

Research suggests potential new strategies for fighting age-related vascular disease

Declining function of cells that help repair the inner lining of blood vessels, known as endothelial progenitor cells, rather than a dwindling supply of the cells, may underlie the increased risk of atherosclerosis and other vascular diseases as people grow older, according to a new study (PDF) in the May 3, 2005, issue of the Journal of the American College of Cardiology.

Soy oil increases heart rate variability

Taking daily supplements of fish or soy oil may improve cardiac function and protect against heart attacks in the short-term. Study results published in the April issue of CHEST, the peer-reviewed journal of the American College of Chest Physicians, are the first to show that soy oil increases heart rate variability (HRV), a measure of cardiac autonomic function.
