  • Typically disregarded brain lesions may warn of heightened stroke risk
    Scientists have found that very small brain lesions noted on brain imaging that would typically be disregarded by clinicians are associated with a heightened risk of stroke and death. The discovery about these tiny lesions -- areas of the brain where tissue may have been damaged by injury or disease -- may help physicians identify people at risk of stroke and death as early as middle age.

  • Two biomarkers linked to severe heart disease found
    A first-of-its-kind animal model to pinpoint two biomarkers that are elevated in the most severe form of coronary disease has been developed by scientists.

  • Heart attack treatment hypothesis 'busted'
    Researchers have long had reason to hope that blocking the flow of calcium into the mitochondria of heart and brain cells could be one way to prevent damage caused by heart attacks and strokes. But in a study of mice engineered to lack a key calcium channel in their heart cells, scientists appear to have cast a shadow of doubt on that theory.

  • How dengue virus adapts as it travels, increasing chances for outbreaks
    A research group is the first to explain the mechanisms that the Dengue virus has developed to optimize its ability to cause outbreaks as it travels across the globe to new places and revisits old ones.

  • New blood pressure guidelines may lead to under treatment of older adults
    In 2014, the Joint National Committee released the eighth update to the blood pressure guidelines (JNC8P). These guidelines included a controversial decision to change the blood pressure goal that may lead to under treatment of adults 60 years of age or older. The JNC8P guidelines set a less stringent goal blood pressure of < 150/90 mmHg for individuals 60 years of age or older compared to the previous <140/90 mmHg goal.
