A rare genetic flaw might be behind sudden neck artery spasms that can trigger strokes in younger people. These spasms, called cervical internal carotid artery vasospasms, cut off blood flow to the brain without warning. Doctors see this mostly in patients under 50, where one moment they’re fine, th
When women enter midlife, their bodies go through big shifts—not just in hormones, but in how they think and feel every day. For women who already deal with heart disease, these changes can get more complicated. Most research about menopause and thinking skills has focused on women without major hea
The ATTICA study followed more than a thousand adults from 2002 to 2022, tracking who developed heart problems over two decades. Researchers looked closely at people carrying extra weight but still showing no metabolic issues, a group called metabolically healthy obesity (MHO). They wanted to see if
A 77-year-old man walked into the hospital one morning, struggling to speak clearly and move his right side. His brain was starved for blood due to a clot blocking an artery. Fast action was needed to restore blood flow before permanent damage set in. Doctors spotted the blockage in a key brain vess
Scientists once saw mitochondria—the powerhouses inside our cells—as fixed residents with one job: producing energy. Now they know these tiny structures are more like delivery trucks zipping between cells, dropping off supplies or picking up garbage. This movement happens with help from three main h
Older fishermen who dive for their work show a mix of health traits that scientists want to understand. Researchers first looked at how the blood vessels, body shape, and everyday habits of these men differ from younger people. They also measured how strong the fishermen’s arms and legs were d
Recent science shows that a simple gas—hydrogen—is more than just a building block of water. Because it is so small, the molecule can slip through cell walls and even the blood‑brain barrier, reaching places that many medicines cannot. Researchers have tested hydrogen in a variety of ways: breathing
The way the weather feels can change how our hearts work. When it is too hot or too cold, people are more likely to have heart attacks, strokes, sudden death and other serious problems. Scientists say the problem is getting worse because global temperatures are rising and extreme weather events ar
Research suggests that adding just a few extra minutes of walking and sleep each day might lower heart disease risk, even if the evidence isn’t rock solid. Experts looked at population data and estimated that 4. 5 more minutes of moderate walking and 11 extra minutes of sleep daily could improve hea
The study explores how a closure tool, used after artery procedures, changes the blood’s movement. These devices seal holes in the femoral artery quickly, cutting down on manual pressure and speeding up healing. Even though many doctors use them routinely, scientists have not fully mapped how the
