How Hypertension Affects the Risk of Stroke



High blood pressure can progress without causing obvious symptoms. However, over time, it can damage blood vessels and increase the risk of having a stroke.

An analysis led by Dr. Deborah Levine of the University of Michigan found that hypertension during adulthood is associated with a greater likelihood of experiencing different types of stroke.

The study compiled information from six studies conducted in the United States between 1971 and 2019. In total, more than 40,000 adults took part, and their health was followed for nearly 22 years.

The researchers focused mainly on systolic blood pressure. It is the top number in a blood pressure reading and represents the pressure exerted by the blood when the heart contracts.

For every average increase of 10 mm Hg in systolic pressure, the likelihood of having a stroke rose by around 20%. This is a statistical association: it does not mean that a single high reading will cause a stroke, but it does show the importance of monitoring blood pressure over the long term.

To understand why regular checkups are so important, it may also help to read why you need a doctor to check your heart regularly.

Ischemic and Hemorrhagic Strokes: Differences and Risks



Ischemic strokes are the most common, accounting for approximately 85% of cases. They occur when a clot or blockage interrupts blood flow to an area of the brain.

Intracerebral hemorrhage, on the other hand, occurs when a blood vessel ruptures and bleeding takes place within the brain. Although it is less common, it can have very serious consequences and requires immediate medical attention.

According to the analysis, an average increase of 10 mm Hg in systolic blood pressure was associated with a 31% higher risk of intracerebral hemorrhage.

The study also found differences among racial and ethnic groups. Black participants were 20% more likely to have an ischemic stroke and had a 67% greater risk of intracerebral hemorrhage than White participants.

Among Hispanic participants, the observed risk of subarachnoid hemorrhage was 281% higher. This type of stroke occurs when there is bleeding between the brain and the tissues that cover it.

These differences should not be interpreted as a direct biological consequence of race or ethnicity. Unequal access to health care, economic conditions, chronic stress, discrimination, diet, and opportunities for early diagnosis may also play a role.

How to Measure and Monitor Blood Pressure at Home



Early diagnosis and consistent blood pressure management are essential. Measuring it just once is not enough: what matters is tracking its changes over time and sharing the record with a health professional.

However, between 2013 and 2018, the proportion of people who kept their blood pressure properly controlled declined in the United States. The decrease was especially concerning among groups facing greater barriers to accessing health care.

Dr. Levine notes that making home monitoring easier could help. Having a blood pressure monitor at home makes it possible to detect changes and understand how blood pressure responds to everyday habits or prescribed treatment.

For a more reliable reading:


  • Rest while seated for five minutes before taking your measurement.

  • Support your back and keep both feet flat on the floor.

  • Rest your arm at heart level.

  • Use a cuff that is appropriate for your arm size.

  • Avoid smoking, exercising, or consuming caffeine for 30 minutes beforehand.

  • Take two readings one minute apart and write down the results.



A single measurement can vary due to nervousness, pain, movement, or inadequate rest. Do not change or stop medications on your own based solely on home readings. If you notice repeatedly high values, consult your doctor.

The cost of devices and a lack of education about how to use them remain barriers. That is why simply recommending home monitoring is not enough: health systems also need to teach people how to use the equipment and make it more accessible.

Habits to Care for Your Blood Pressure and Heart



Keeping blood pressure under control does not depend on a single action. Rest, physical activity adapted to your abilities, a balanced diet, and medical follow-up are all part of proper care.

Stress and anxiety can also temporarily raise blood pressure and make it harder to maintain healthy habits consistently. Breathing calmly, taking breaks, walking, or seeking emotional support may help, although these practices do not replace medical treatment when hypertension is present.

The American Heart Association also offers recommendations on how to measure blood pressure and keep a record. Bringing those notes to your appointment can make more personalized decisions easier.

A diet based on vegetables, fruits, legumes, whole grains, fish, and healthy fats can also support cardiovascular health. To learn more, you can explore the foundations of the Mediterranean diet.

Signs of a Stroke That Require Immediate Attention



In addition to prevention, it is important to recognize warning signs. Seek emergency help if you suddenly experience weakness or numbness on one side of the body, difficulty speaking, confusion, loss of balance, vision problems, or a very severe headache that is different from usual.

Do not wait for the symptoms to disappear, and do not drive yourself. With a stroke, every minute counts.

Your blood pressure readings are much more than numbers on a screen. They are a signal that can help you take action in time. Measuring it correctly, seeking medical advice for persistent changes, and maintaining realistic habits are concrete ways to protect your brain and your heart. ❤️
