Cardiovascular Research: New technology promises fast, accurate stroke diagnosis ♦ Overweight, obesity early in life increase risk of cardiac death

Ultrasound examinations can identify patients at risk of stroke Ultrasound, a non-invasive technique commonly used to study the presence of atherosclerosis disease in blood vessels, can be used to identify patients at increased risk of future stroke who could benefit from surgery. Since surgical treatment to prevent stroke is only considered beneficial to some, ultrasound can prove useful in preventing unnecessary surgical intervention.
Heart disease patients who sit a lot have worse health even if they exercise Patients with heart disease who sit a lot have worse health even if they exercise, reveals research. Patients in the study wore an activity monitor during their waking hours for nine days. The monitors allowed the researchers to measure how long patients spent being sedentary, or doing light, moderate or vigorous levels of physical activity. The researchers also assessed various markers of health including body mass index and cardiorespiratory fitness.
New technology promises fast, accurate stroke diagnosis A new approach to identifying biomarkers in blood has proven successful in helping diagnose stroke, and the technology could be expanded to diagnose such conditions as concussion, some forms of dementia, and some types of cancer and heart disease.
Overweight, obesity early in life increase risk of cardiac death Overweight and obesity throughout adulthood, and especially elevated weight in early adulthood, were associated with increased risk of sudden cardiac death in a 32-year study of more than 72,000 women.
