Blood Pressure News and Research

RSS

Blood Pressure is the force of circulating blood on the walls of the arteries. Blood pressure is taken using two measurements: systolic (measured when the heart beats, when blood pressure is at its highest) and diastolic (measured between heart beats, when blood pressure is at its lowest). Blood pressure is written with the systolic blood pressure first, followed by the diastolic blood pressure (for example 120/80).

Retina vascular fingerprint offers non-invasive way to predict stroke risk

A vascular 'fingerprint' on the light sensitive tissue layer at the back of the eye-the retina-can predict a person's risk of stroke as accurately as traditional risk factors alone, but without the need for multiple invasive lab tests, finds research published online in the journal Heart.

High blood pressure may not harm brains of 90-year-olds, study finds

A study led by the University of California, Irvine has found cardiovascular conditions such as high blood pressure and diabetes, which are known to contribute to brain blood vessel damage in younger populations, not to be associated with an increased risk of such harm in individuals 90 and older.
