What do widening pulse pressures mean?
A widened (or larger) pulse pressure occurs with several diseases, including aortic regurgitation, aortic sclerosis (both heart valve conditions), severe iron deficiency anemia (reduced blood viscosity), arteriosclerosis (less compliant arteries), and hyperthyroidism (increased systolic pressure).
How do you calculate widening pulse pressure?
To calculate pulse pressure, simply subtract your systolic blood pressure (top number) from your diastolic blood pressure (bottom number). Like blood pressure, it is measured in millimeters of mercury (mmHg). For example, if your blood pressure is 120/80 mmHg, your pulse pressure is 40 mmHg (120 – 80).
What is wide pulse pressure in aortic regurgitation?
A widened pulse pressure is often present due to increased stroke volume, as previously described. When heart failure develops, the pulse pressure decreases and the peripheral signs of aortic regurgitation, listed below, are lessened.
Why does aortic stenosis cause narrow pulse pressure?
Aortic stenosis can reduce ventricular stroke volume due to increased afterload (which decreases ejection velocity). The reduced stroke volume decreases the aortic pulse pressure, and the mean aortic pressure will fall if the reduced cardiac output is not offset by an increase in systemic vascular resistance.
How does atherosclerosis cause wide pulse pressure?
High blood pressure or fatty deposits on the walls of the arteries (atherosclerosis) can make the arteries stiff. The greater the pulse pressure, the stiffer and more damaged the blood vessels are thought to be. Treating high blood pressure usually reduces pulse pressure.
What is pulse pressure formula?
The top number (systolic) minus the bottom number (diastolic) is the pulse pressure. For example, if the resting blood pressure is 120/80 millimeters of mercury (mm Hg), the pulse pressure is 40 — which is considered a healthy pulse pressure.
What is normal range for pulse pressure?
A normal pulse pressure range is between 40 and 60 mm Hg. A pulse pressure reading is considered low when it’s less than 40 mm Hg. Low pulse pressure can indicate decreased cardiac output.
How do you measure severity of aortic regurgitation?
Echocardiography has become the standard method for evaluating aortic regurgitation severity. Other methods such as cardiac catheterisation are not routine except where the data is non-diagnostic or discrepant with clinical data.
Why is pulse pressure high in aortic regurgitation?
In a patient with aortic regurgitation the heart has to increase the stroke volume in order to keep the cardiac output constant. This causes an increase in the systolic blood pressure. At the same time there is a decrease in the diastolic blood pressure directly caused by the retrograde diastolic blood flow.
What does a wide gap between systolic and diastolic mean?
A wide pulse pressure — sometimes called a high pulse pressure because the number is greater — means there’s a wide difference between the top and bottom numbers. For individuals who aren’t physically active, wider pulse pressures can indicate serious problems either now or in the future.
What is a bad pulse pressure?
High pulse pressure (wide PP) is considered to be abnormal over 50 mm Hg. Normal pulse pressure range is between 30 and 50 mm Hg. Causes of wide pulse pressure are similarly broad; the most common of these are atherosclerosis, slow heart rate (bradycardia), low blood volume, and hyperthyroidism.
How is widened pulse pressure treated?
How’s it treated?
- Lose weight. If you are overweight, losing even 10 pounds can help reduce blood pressure.
- Exercise. Try to get at least 30 minutes of exercise more days of the week than not.
- Stop smoking.
- Reduce your daily sodium intake.
- Avoid drinking too much alcohol.
- Take steps to reduce stress.
Is wide pulse pressure bad?
In the absence of an underlying cause, wide pulse pressure is a sign of deteriorating cardiovascular health and carries increased risk for mortality, disease progression, and adverse clinical outcomes in chronic diseases including cardiovascular disease and chronic kidney disease.
How is wide pulse pressure treated?
What is considered severe aortic regurgitation?
Acute severe aortic regurgitation (AR) comes about when there is rapid disruption of the anatomic integrity of the aortic valve. As a consequence, the sudden imposition of a large regurgitant volume leads to a precipitous increase in left ventricular diastolic pressure and a decrease in forward stroke volume.
What is normal aortic regurgitation?
In aortic valve regurgitation, the aortic valve doesn’t close properly, causing blood to flow backward from the body’s main artery (aorta) into the lower left heart chamber (left ventricle).
What is SR 522 in Snohomish?
SR 522 in Snohomish County is an increasingly important north-south route connecting communities between Woodinville and Monroe. One section between Paradise Lake Road in Maltby and the Snohomish River remains one-lane in each direction.
What are the plans for the SR 522 project?
We plan to widen the highway to two lanes in each direction, build a new eastbound bridge at Fales Road/Echo Lake Road and improve the SR 522 intersection at Paradise Lake Road.
When was SR 522 widened to Paradise Lake Road?

Can I purchase property for SR 522 right of way?
Although there is no funding for construction at this time, property owners along SR 522 may be contacted by WSDOT’s Real Estate Services division regarding purchase of property for right of way to accommodate a wider highway and improved interchanges. This map shows SR 522 between Paradise Lake Road in Maltby and the Snohomish River.
