what blood pressure should you go to hospital
A hypertensive crisis is a severe increase in blood pressure that can lead to a stroke. Extremely high blood pressure â a top number (systolic pressure) of 180 millimeters of mercury (mm Hg) or higher or a bottom number (diastolic pressure) of 120 mm Hg or higher â damages blood vessels. They become inflamed and may leak fluid or blood. As a result, the heart may not be able to pump blood effectively.
