Isolated systolic hypertension: What are the possible causes?

Isolated systolic hypertension is characterized as a systolic blood pressure higher than 140 mm Hg with a diastolic pressure lower than 90 mm Hg. Always bear in mind that the systolic blood pressure is produced by the arteries while the heart is contracting while diastolic is the pressure that remains while heart relaxes.

Always bear in mind that isolate systolic hypertension is quite common as individuals start to age and its main cause appears to be linked to the changes during the aging process on the blood vessels. An increased systolic blood pressure is considered as a risk factor for stroke and heart attack.

Essential hypertension

In most cases of elevated blood pressure, it is called essential which simply means that it occurs without any other medical condition and usually multifactorial which means that there are various factors responsible.

This is often linked to lifestyle choices and affected by dietary levels of caffeine, salt and alcohol. It is quite prevalent among obese and those who have a sedentary lifestyle. The intake of nicotine by cigarette smoking and chewing on tobacco can be associated with the level of blood pressure in the body.

Heredity and other poorly recognized factors might play a part as well. Even though essential hypertension is not limited to the systolic reaching, many individuals with the condition have higher elevations in the systolic pressure than the diastolic. This might be linked to a hereditary predisposition, lifestyle factors or the cardiovascular make-up.

An increased systolic blood pressure is considered as a risk factor for stroke and heart attack.

Isolated systolic hypertension can also be caused by hyperthyroidism. The thyroid gland is vital in managing the overall metabolism and activity of the body. There are circumstances in which it becomes overly active for various reasons, but the hyperactivity can lead to increased blood pressure and heart rate.

Aortic stiffness

A stiffened aorta might also be considered as a cause of isolated systolic hypertension. Always bear in mind that the aorta is the major artery that exits the heart and functions as a conduit for the flow of blood to the entire body. As the body ages, this vessel starts to lose elasticity and compliance.

The increased rigidity results to an increase in the pressure since the walls have less give and could no longer absorb the force exerted by the pumping heart. Remember that these factors do not play a role once the heart relaxes, thus the diastolic pressure is not affected.


It is important to note that aldosterone is a hormone that controls the sodium levels and blood volume. This can become elevated via various mechanisms. Once this occurs, the increased systolic blood pressure can develop. The high levels of aldosterone are a main cause of secondary hypertension.
