WEDNESDAY, Aug. 16, 2017 -- Despite some early concerns, a new study suggests the powerful cholesterol drugs known as PCSK9 inhibitors may not cause memory problems or other mental symptoms.
The drugs, which include evolocumab (Repatha) and alirocumab (Praluent), were approved in the United States in 2015. That came after trials showed they can dramatically slash LDL cholesterol (the "bad" kind), including in people with a genetic condition that often causes premature heart disease.
THURSDAY, Aug. 17, 2017 -- Five years after heart bypass surgery, patients whose operation was done using a heart-lung pump lived longer than those whose surgeons didn't use the device, a new study finds.
Since the 1990s, two different approaches have been commonly used by heart surgeons to perform coronary artery bypass graft operations. Coronary artery bypass creates new routes for blood to flow to the heart because old routes are blocked by plaque in the artery. A piece of blood vessel is taken from another area of the body (often the leg) and used to "bypass" a blocked vessel going to the heart, according to the U.S. National Heart, Lung, and Blood Institute.
MONDAY, July 24, 2017 -- A wave of anti-science skepticism may put people with high cholesterol at risk if they're convinced to quit life-saving statin medications, heart experts warn.
An "internet-driven cult" is attacking the safety and effectiveness of cholesterol-lowering statins, despite mounds of clinical trial data showing the drugs work and produce minimal side effects, said Dr. Steven Nissen, chairman of cardiovascular medicine at the Cleveland Clinic.
WEDNESDAY, July 19, 2017 -- Folks with heart-healthy habits in their 20s tend to have larger, healthier brains in their 40s -- brains that may be better prepared to withstand the ravages of aging, a new study reports.
Twentysomethings who closely followed the "Life's Simple 7" guidelines from the American Heart Association had brains in middle age that appeared more than a decade younger than those who didn't follow the guidelines at all, said lead researcher Michael Bancks. He's a postdoctoral fellow at the Northwestern University Feinberg School of Medicine in Chicago.
TUESDAY, July 11, 2017 -- Using a breathing device to treat sleep apnea may help you get a good night's rest, but it might not lower your risk of dying from a stroke or heart condition, a new analysis suggests.
Looking at data from 10 clinical trials, researchers found that apnea patients' risk of cardiovascular-related death remained the same whether or not they used a CPAP (continuous positive airway pressure) machine.
