PULSE PRESSURE

Pulse pressure mathematically  is the difference between systolic and diastolic blood pressure. 

Pulse pressure reflects the stroke volume and compliance of the arterial system.

PULSE PRESSURE > 50 % of Systolic Blood Pressure (or > 40 mmHg):

• Hypertension ; 
• Age; 
• Aortic regurgitation; 
• Patent ductus arteriosus;
• Ruptured aneurysm of the sinus of Valsalva; 
• Fever;
• Anemia; 
• Hyperthyroidism;
• Pregnancy; 
• Arteriovenous fistula; 
• Paget’s disease

PULSE PRESSURE  < 25% of Systolic Blood Pressure:

• Tamponade; 
• Heart failure; 
• Cardiogenic shock; 
• Aortic stenosis.
