Pulse pressure is the difference between the top and bottom numbers in a blood pressure reading, reflecting the force your heart generates with each beat1 . It can provide early insight into cardiovascular health before symptoms develop and tends to increase naturally with age due to arterial stiffening2 . Understanding your pulse pressure can help predict risks for heart disease, stroke, and other cardiovascular events2 3.
Measuring Your Pulse Pressure
Pulse pressure is calculated by subtracting the diastolic blood pressure (the lower number) from the systolic blood pressure (the upper number) in a blood pressure reading4 . For example, a typical blood pressure of 120/80 mmHg results in a pulse pressure of 40 mmHg, which is considered normal and healthy4 1.
- Systolic pressure measures the force in your arteries when your heart beats5 .
- Diastolic pressure measures the pressure in your arteries between heartbeats5 .
- Pulse pressure = systolic pressure − diastolic pressure4 .
- Pulse pressure is different from pulse rate, which counts heartbeats per minute4 .
- Regularly checking your blood pressure allows you to calculate your pulse pressure easily2 .
💡 Did You Know?
Pulse pressure is determined from the two numbers of a blood pressure reading. The top number is called systolic pressure, which is the pressure in the arteries when the heart beats5 .
Blood Pressure and Pulse Pressure Basics
Blood pressure readings consist of two numbers: systolic and diastolic pressures4 . The difference between these numbers is your pulse pressure, representing the force your heart generates with each beat1 . A normal pulse pressure is approximately 40 mmHg, which reflects healthy arterial compliance and cardiac function6 1.
Pulse pressure tends to increase with age due to arteriosclerosis (hardening of the arteries) and vascular stiffening, which reduce arterial elasticity7 2. This stiffening causes systolic pressure to rise and diastolic pressure to fall, widening the pulse pressure2 . Conditions such as diabetes and chronic kidney disease can also contribute to arterial stiffness and increased pulse pressure2 .
Pulse pressure is an important cardiovascular risk marker. A higher pulse pressure indicates that your heart is working harder and your arteries are less flexible, increasing the risk of heart and circulatory problems2 1. It is also a predictor of future cardiovascular events, including stroke and myocardial infarction8 4.
- Pulse pressure is influenced by stroke volume and vascular resistance9 .
- A pulse pressure greater than 60 mmHg is considered wide and may signal arterial damage4 .
- A pulse pressure less than 25 mmHg is considered narrow and may indicate poor heart function4 .
- Monitoring pulse pressure can help identify cardiovascular risk before symptoms appear2 .
- Pulse pressure is an independent predictor of cardiovascular mortality, especially in older adults3 .

Narrow, Normal, and Wide Pulse Pressure Ranges
Pulse pressure can be classified as narrow, normal, or wide, each with distinct health implications. Understanding these ranges helps in assessing cardiovascular risk and guiding clinical decisions4 .
Wide Pulse Pressure
A wide pulse pressure is defined as 60 mmHg or higher and is linked to increased cardiovascular risk, especially in older adults7 4. It often reflects arterial stiffening due to atherosclerosis, which is the buildup of fats, cholesterol, and other substances in artery walls7 10. This stiffening raises systolic pressure and lowers diastolic pressure, increasing the workload on the heart and reducing coronary blood flow3 .
Other causes of wide pulse pressure include aortic regurgitation (a heart valve condition), hyperthyroidism, and athlete’s heart—a condition in athletes characterized by increased cardiac output7 411. A wide pulse pressure is an independent predictor of all-cause, cardiovascular, and coronary mortality3 .
- Wide pulse pressure increases risk for heart disease, stroke, and heart rhythm disorders4 210.
- It is associated with left ventricular hypertrophy due to increased heart workload3 .
- A pulse pressure over 100 mmHg is considered truly widened and particularly concerning2 .
- Every 10 mmHg increase in pulse pressure raises coronary artery disease risk by 23% 2.
- Some healthy athletes may have wide pulse pressure due to enhanced cardiac function4 .
In a large population of men with a relatively low cardiovascular risk, a wide pulse pressure is a significant independent predictor of all-cause, cardiovascular, and especially coronary mortality.

Narrow Pulse Pressure
Narrow pulse pressure is typically defined as less than 25 mmHg or less than 25% of the systolic blood pressure4 11. It often indicates reduced cardiac output, meaning the heart is not pumping enough blood to meet the body’s needs4 . This can occur in conditions such as heart failure, aortic stenosis, cardiac tamponade, or hypovolemia (low blood volume) 411.
Narrow pulse pressure may be an early sign of life-threatening hemorrhagic shock in trauma patients and can aid in early assessment and intervention planning12 . Symptoms associated with low blood pressure and narrow pulse pressure include dizziness, blurred vision, and weakness4 .
- Narrow pulse pressure may signal heart valve problems or heart failure4 .
- It can result from severe blood loss or shock states4 .
- Early detection is important for timely treatment and improved outcomes12 .
- Low pulse pressure is linked to poor heart function and reduced blood flow2 .
- Monitoring pulse pressure helps differentiate types of cardiovascular dysfunction4 .
Managing Your Pulse Pressure
Managing pulse pressure involves addressing underlying causes and adopting lifestyle changes to support cardiovascular health. Both wide and narrow pulse pressures are associated with increased risk of adverse events, so maintaining an ideal pulse pressure around 40 mmHg is beneficial4 .
Causes of wide pulse pressure include atherosclerosis, aortic regurgitation, hyperthyroidism, and athlete’s heart7 4. Narrow pulse pressure may result from heart failure or hypovolemia4 . Treatment focuses on managing these conditions and improving arterial health.
Pulse pressure is a vital sign that can reveal hidden cardiovascular risks before symptoms arise. Monitoring and managing pulse pressure through lifestyle and medical care can help prevent heart attacks, strokes, and other serious events2 3.
Lifestyle modifications recommended by the American Heart Association can help maintain healthy blood pressure and pulse pressure4 :
- Follow a heart-healthy diet rich in fruits, vegetables, legumes, and whole grains4 .
- Limit sodium and saturated fat intake to reduce arterial stiffness4 .
- Engage in regular physical activity to improve cardiovascular function4 .
- Avoid smoking and manage stress to protect blood vessels5 .
- Maintain a healthy weight and get 7 to 9 hours of sleep per night5 .
If you have abnormal pulse pressure or blood pressure concerns, consult a healthcare provider for personalized advice and possible medical management4 . Medications may be necessary to control blood pressure, but they do not always lower pulse pressure directly5 .
For a given mean blood pressure, lower pulse pressure amplification might be associated with unfavorable hemodynamic effects for the central arteries and the heart.

Key Takeaways
- Pulse pressure is the difference between systolic and diastolic blood pressure and reflects the force the heart generates with each beat1 .
- A normal pulse pressure is about 40 mmHg; values above 60 mmHg are wide and linked to increased cardiovascular risk, while values below 25 mmHg are narrow and may indicate heart failure or shock4 11.
- Wide pulse pressure often results from arterial stiffness due to atherosclerosis and is an independent predictor of cardiovascular and coronary mortality7 3.
- Narrow pulse pressure signals reduced cardiac output and can be an early warning sign in trauma or heart failure12 4.
- Lifestyle changes such as a heart-healthy diet, regular exercise, and stress management can help maintain healthy pulse pressure and reduce cardiovascular risk4 5.
