But current findings suggest that isolated systolic hypertension does, in fact, have a serious impact on the cardiovascular health of young adults. As such, researchers encourage future research to better identify and treat young adults with isolated systolic hypertension who are at greatest risk for heart events.
For Clinicians. Loading results CardioSmart News. High Blood Pressure News Article Having a high systolic blood pressure increases risk of heart disease and death in young adults, even when diastolic blood pressure is normal, according to a study published in the Journal of the American College of Cardiology.
However, either an elevated systolic or an elevated diastolic blood pressure reading may be used to make a diagnosis of high blood pressure. According to recent studies, the risk of death from ischemic heart disease and stroke doubles with every 20 mm Hg systolic or 10 mm Hg diastolic increase among people from age 40 to The abbreviation mm Hg means millimeters of mercury.
Mercury was used in the first accurate pressure gauges and is still used in medicine today as the standard unit of measurement for pressure. While both are indications of health, blood pressure and heart rate pulse are two separate measurements. Learn more about the difference between blood pressure and heart rate.

Elevated Elevated blood pressure is when readings consistently range from systolic and less than 80 mm Hg diastolic. Hypertension Stage 1 Hypertension Stage 1 is when blood pressure consistently ranges from systolic or mm Hg diastolic.
This is because, like other types of high blood pressure, ISH can also contribute to the risk of heart attack and stroke. It can also be an indicator of other conditions such as anemia and hyperthyroidism.
ISH is the most common type of high blood pressure in people older than 65, according to Mayo Clinic. Additionally, according to the American College of Cardiology, ISH can increase the risk of heart disease and death in young adults. Blood pressure involves both 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.
Plaques, which are fatty deposits on the artery wall, can also contribute to 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 for high blood pressure. However, there are some medical conditions that can cause someone to develop ISH. These conditions often have effects on the circulatory system, which can damage blood vessels or contribute to artery stiffening.
Some of these conditions include:. There are many types of anemia, but iron deficiency anemia is the most common. Damage can be caused to your blood vessels as your heart works harder to pump blood to the tissues of your body in order to deliver sufficient oxygen.
Diabetes happens when the amount of glucose in your blood is too high. Insulin normally controls blood glucose levels. Over time, high glucose levels in your blood can lead to a variety of problems, including those with the heart and circulatory system.
Hyperthyroidism , or overactive thyroid, occurs when your thyroid gland produces more thyroid hormones than necessary. This surplus of thyroid hormone can affect almost every organ in your body, including your heart and circulatory system.
Because blood oxygen levels can drop when breathing stops, obstructive sleep apnea can strain your cardiovascular system and lead to increases in blood pressure. When high blood pressure is left uncontrolled, it can cause damage to your arteries. This can affect various parts of your body and can increase your risk for the following conditions:.
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. The second number is your diastolic blood pressure. There are several different blood pressure categories, which are currently defined as the following:. ISH is when you have a systolic blood pressure reading of mm Hg or higher, and a diastolic blood pressure reading of less than 90 mm Hg.
ISH can be treated like other forms of hypertension.
