Systolic pressure is the force of blood against artery walls when the heart contracts, while diastolic pressure reflects the force when the heart relaxes and refills. Both systolic and diastolic blood ...

Diastolic dysfunction arises when the left ventricle fails to relax or fill normally during diastole, often despite a preserved ejection fraction. This impairment leads to elevated filling pressures, ...

High blood pressure, including pre-hypertension, is a major global health economic issue, accounting for about half of the total cases of stroke and ischaemic heart disease. It is responsible for ...

S1 and S2 are the normal heart sounds you hear when the heart valves close. Heart murmurs are extra sounds that can be heard during systole, diastole, or as a continuous sound. S3 and S4 are abnormal ...
