“Blood pressure bottom number high” refers to elevated diastolic blood pressure, which measures the pressure of the heart’s ventricles when they relax and fill with blood. For example, a reading of 120/85 mmHg indicates a high diastolic blood pressure of 85 mmHg.
Diastolic blood pressure is important because it reflects the resistance to blood flow in the arteries. High diastolic blood pressure can lead to a number of health issues, including heart attack, stroke, and kidney disease. In 1905, Russian physician Nikolai Korotkov invented the sphygmomanometer, which allowed for the non-invasive measurement of blood pressure.
