In general, the normal value of pulse pressure difference is 20~60mmHg. 60~70mmHg pulse pressure difference is increased pulse pressure difference, suggesting that the elasticity of the blood vessel wall decreases, which will lead to an increased risk of cardiovascular and cerebrovascular accidents. Patients with increased pulse pressure difference generally suffer from atherosclerosis with plaque, and their cardiovascular and cerebral vascular load increases, plaque rupture easily, resulting in thrombus formation within the plaque, and ischemic symptoms appear in the organs supplied by the blood vessel, which can lead to myocardial infarction, stroke, and transient cerebral ischemic attack. Those who find that the pulse pressure difference increases should go to the hospital for examination in time and be treated under the guidance of the doctor to avoid serious adverse consequences.
