When the blood travels through the dense network of our circulatory system, it exerts certain amount of force on the walls of blood vessels, which is known as blood pressure. As we all know, the heart does an important job of supplying (pumping) fresh oxygenated blood, that is then circulated through arteries to different parts of the body. When the heart pumps, it exerts force on the blood, thus pushing it through the veins. During this pumping action, the heart contracts and beats. It is obvious that when the heart beats the blood pressure is maximum and when it is in relaxed state (at rest) blood pressure is at its minimum. Read more on high blood pressure.

The maximum blood pressure achieved during heart contraction, is referred as systolic blood pressure. When the heart does not beat and is relaxing, the blood pressure is found to be lowest and is known as isolated diastolic hypertension. For a healthy person the device shows a reading of 120 mm Hg systolic pressure where as the diastolic pressure is around 80mm Hg. Read more on uncontrolled hypertension.

What is Isolated Systolic Hypertension (ISH)
In this condition, systolic blood pressure abnormally increases but surprisingly the diastolic blood pressure is within the normal range (80-90 mm Hg). The reading indicates a sharp rise in systolic blood pressure, which is more than 140 mm Hg but diastolic blood pressure does not deviate from its normal level. Read more on high systolic blood pressure.

Is Isolated Systolic Hypertension Harmful?
A decade ago, this version of hypertension was considered to be a harmless condition and doctors thought that increased diastolic pressure was a cause of concern. Doctors did not give much importance to rise in systolic hypertension. However, today doctors are of the firm opinion that high systolic hypertension cannot be ignored, as it can lead to health issues that can affect the kidneys, heart and may even cause stroke. Read more on acute hypertension.

Isolated Systolic Hypertension in the Elderly - Symptoms
Generally ISH strikes in older after the age of 50 and the person affected often complains about frequent episodes of headache. The heart may also produce some abnormal sounds that are not the same as heart beats. Frequent urination and in some severe vision abnormalities are some of the symptoms of persistent ISH.

Isolated Systolic Hypertension - Causes
ISH is classified as an age related disorder and usually does not affect children. With age, there might be some abnormal changes in the pattern of blood circulation or the functioning of the heart, which may lead to ISH. Also, people diagnosed with diabetes or carry too much body weight are susceptible to ISH. This condition can also occur when the arteries significantly lose their elasticity and become stiff. It is observed that loss of flexibility of arteries can reduce normal blood flow. In such a case, the heart has to push the blood with greater force to ensure proper blood circulation to different organs. The extra force exerted by the heart, ultimately leads to what is known as isolated systolic hypertension.

Isolated Systolic Hypertension Treatment
Medications may be prescribed to lower elevated systolic blood pressure. Apart from medicines, making lifestyle modifications that support healthy blood pressure levels, is necessary. The medicine will work when the person gives up leading a sedentary lifestyle. As aforementioned, being overweight predisposes a person to this form of hypertension. So, maintaining a healthy weight is essential to manage isolated systolic hypertension effectively.

To know more about different forms of hypertension, read:

* Diastolic Hypertension
* Accelerated Hypertension
* Benign Hypertension

When it comes to high blood pressure diet, avoiding salty food is essential. Doctors specifically recommend to follow a low salt diet. An increased salt intake can worsen hypertension and put a person in the risk zone of wide range of cardiovascular diseases. Patients are also advised to increase consumption of potassium and calcium rich foods. Both calcium and potassium can help to control isolated systolic hypertension. Daily exercise will not help to control weight but also lower isolated systolic hypertension. Physical activities like brisk walking, jogging and cycling for a period of 30 minutes will ensure that isolated systolic hypertension does not become troublesome and interferes with day-to-day routine.
