What Are The Causes Of Isolated Systolic Hypertension
Blood pressure involves how much blood your heart pumps every minute, as well as the pressure exerted on the walls of your arteries by that blood.
As you age, your arteries lose some of their natural elasticity and are less able to accommodate the rush of blood. Plaque, which is fatty deposits on the artery wall, can also contribute to the stiffening of the arteries.
Blood pressure particularly systolic blood pressure naturally tends to increase with age. Because of this, there may be no identifiable cause of high blood pressure.
However, there are some medical conditions that can cause you to develop ISH. These conditions can affect your circulatory system, which can damage your blood vessels or contribute to artery stiffening.
Some of these conditions include:
Medications For High Blood Pressure
Many people with hypertension need medication, in addition to lifestyle changes, to control their blood pressure. In fact, with medication, high blood pressure can be controlled quickly, often in a matter of days. Following the proper dosage and instructions with medication and communicating regularly with your doctor is just as important.
Common high blood pressure medications include diuretics , beta blockers , calcium channel blockers and ace inhibitors .
What Problems Can It Cause
All types of high blood pressure, including isolated systolic hypertension, can slowly damage the inside of your arteries and cause tiny tears in their walls. A chemical called LDL cholesterol can build up in those damaged blood vessels and form a layer called plaque. That makes your arteries narrower and raises your blood pressure even higher.
When that happens, the arteries that carry oxygen to your heart can get blocked, and that can lead to a heart attack or a stroke . It also can make blood vessels in your brain burst, and that can cause a stroke, too.
In other parts of your body, it can strain the blood vessels in your eyes and make you lose your eyesight or damage the arteries around your kidneys so they donât filter your blood the way they should.

Treating High Blood Pressure
Treatment for high blood pressure will depend on your blood pressure levels and your associated risk of developing a cardiovascular disease, such as a heart attack or stroke.
There are seven main risk factors for developing a cardiovascular disease. These are:
- having a high level of cholesterol in your blood
- having a family history of cardiovascular disease .
What Is Normal Blood Pressure
Your heart is a powerful muscle that contracts forcefully to pump blood through your circulatory system, delivering oxygen and nutrients to all of your organs. Since its a closed system, the heart is responsible for maintaining blood pressure throughout your blood vessels.
In normal, healthy adults, blood pressure readings should be less than 120/80 mmHg. This means that your systolic blood pressure should be below 120 millimeters of mercury. Your diastolic blood pressure should be less than 80 millimeters of mercury.
Doctors consider elevated blood pressure to be below 130/80 mmHg but above 120/80 mmHg. If you do not monitor and control your blood pressure, you are likely to develop hypertension. This is when your blood pressure consistently ranges between 130-139 mmHg systolic and 80-89 mmHg diastolic. Doctors may prescribe medication and lifestyle changes to reduce the risk of heart disease and stroke.

ISH can be treated like other forms of hypertension. The goal is to reduce your systolic blood pressure to below 140 mm Hg. This can be accomplished by lifestyle changes, medication, or both.

If theres an underlying condition thats causing or contributing to ISH, your doctor will work to treat that as well.

Angiotensin Ii Receptor Blockers
The muscles surrounding blood vessels have angiotensin II receptors on which angiotensin II binds, causing muscle contraction and narrowing of the vessels. The narrowing of blood vessels can cause diastolic hypertension, and angiotensin II receptor blockers block this action, preventing the binding. This enables the blood vessels to widen, leading to lower blood pressure.
These medications have a similar effect to ACE inhibitors but differ in how they work. While ARBs prevent the binding of angiotensin II to the receptors in muscles surrounding blood vessels, ACE inhibitors prevent the formation of angiotensin II.
Below are examples of ARBs to treat high diastolic blood pressure:

Systolic Vs Diastolic Blood Pressure
A blood pressure reading consists of two numbers your systolic blood pressure and your diastolic blood pressure. But what do these numbers actually mean?
The first number is your systolic blood pressure. Its a measurement of the amount of pressure placed on the walls of your arteries when your heart beats.

There are many things you can do to lower your blood pressure overall. Your doctor may recommend a few lifestyle changes, such as increasing exercise and improving your diet, as well as blood pressure medication.

Sensible lifestyle changes to reduce diastolic blood pressure include:

- Reducing your salt intake to between 1.5 and 4 grams per day
- Drinking plenty of fluids, and avoiding alcohol
- Giving up smoking
- Monitoring blood pressure levels at home and keeping a closer eye on your health
