The risk of stroke increases continuously above blood pressure (BP) levels of approximately 115/75 mm Hg. Since the association is steep, and BP levels are high in most adult populations, almost two thirds of stroke burden globally is attributable to nonoptimal BP (ie, >115/75 mm Hg).
A high blood pressure reading above 130/80 mm Hg can increase the risk of stroke. Elevated blood pressure can cause various physiological changes, such as damage to the blood vessels of the brain and bleeding in the brain. These changes can cause ischemic or hemorrhagic strokes or strokes due to small vessel disease.
Extremely high blood pressure can damage blood vessels and weaken arteries in the brain, increasing the risk of stroke. Blood pressure readings above 180/120 mmHg are considered stroke-level, dangerously high, and require immediate medical attention.
High blood pressure can cause the arteries that supply blood and oxygen to the brain to burst or be blocked, causing a stroke. Brain cells die during a stroke because they do not get enough oxygen. Stroke can cause serious disabilities in speech, movement, and other basic activities.
Background and Purpose— Although stroke is strongly associated with hypertension, some individuals with normal blood pressure (BP) experience a stroke.
The Hypertension Danger Zone
If your systolic is over 180 or your diastolic is above over 120, you may be having a hypertensive crisis, which can lead to a stroke, heart attack, or kidney damage. Rest for a few minutes and take your blood pressure again. If it's still that high, call 911.
Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke. One study found that 43% of stroke patients experienced mini-stroke symptoms up to a week before they had a major stroke.
Normal pressure is 120/80 or lower. Your blood pressure is considered high (stage 1) if it reads 130/80. Stage 2 high blood pressure is 140/90 or higher. If you get a blood pressure reading of 180/110 or higher more than once, seek medical treatment right away.
Call 9-1-1 immediately if any of these signs of stroke appear: Numbness or weakness in the face, arm, or leg; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Trouble walking, dizziness, or problems with balance; severe headache with no known cause.
Sleeping on the left side is the best sleeping position for high blood pressure, as it relieves pressure on the blood vessels that return blood to the heart. These vessels are located on the right side of the body and can be compressed by slowing its circulation if you sleep on your right side.”
Still, you can make lifestyle changes to bring your blood pressure down. Something as simple as keeping yourself hydrated by drinking six to eight glasses of water every day improves blood pressure. Water makes up 73% of the human heart,¹ so no other liquid is better at controlling blood pressure.
What is Pre-Stroke? Sometimes, there is a smaller, temporary clot that is quickly resolved, though the symptoms will be similar thanks to the effect such clots have on the brain. This is known as a Transient Ischemic Attack (TIA) or “Pre-Stroke,” and often points to a more life-threatening attack on its way.
What is the link between high blood pressure and stroke? High blood pressure can lead to stroke in different ways. It can lead to blood clots in the brain, and can damage the tiny blood vessels deep inside the brain. It can also make a stroke due to bleeding in the brain more likely.
In other words, once blood pressure rises above normal, subtle but harmful brain changes can occur rather quickly—perhaps within a year or two. And those changes may be hard to reverse, even if blood pressure is nudged back into the normal range with treatment.
If your readings are higher or lower than the healthy limits, the diagnosis can be as follows: Elevated high blood pressure: Any value that ranges between 120/80 and 130/80mm Hg. Hypertensive emergency: 180/120mm Hg and above. If you record these values, you should go to the ER immediately as this is life-threatening.
When you are stressed, your body sends stress hormones — adrenaline and cortisol — into the bloodstream. These hormones create a temporary spike in blood pressure, causing your heart to beat faster and blood vessels to narrow. When the stressful situation is over, blood pressure goes back to its normal level.
Moderate or severe headaches, anxiety, shortness of breath, nosebleeds, palpitations, or feeling of pulsations in the neck are some signs of high blood pressure. Often, these are late signs that high blood pressure has existed for some time, therefore annual checks are recommended for all adults.
A person experiencing a TIA might feel sudden weakness or numbness on one side of the body, have slurred speech, have trouble seeing or talking, and feel confused. The person may experience a combination of these symptoms at the same time. “The real takeaway?
“If you have an inability to speak words, notice food or liquid falling out of your mouth due to facial droop, you could be having a stroke. If you experience numbness in your face or extremities, can't move an arm or leg or have a sudden onset of double vision or dizziness — those are other possible stroke symptoms.”
A silent stroke refers to a stroke that doesn't cause any noticeable symptoms. Most strokes are caused by a clot that blocks a blood vessel in the brain. The blockage prevents blood and oxygen from reaching that area, causing nearby brain cells to die.
Blood Pressure Crisis - Call Doctor! - Systolic pressure readings of over 180 mm Hg or a diastolic pressure of 120 mm Hg or higher, require urgent attention.
“The American Heart Association states that a reading of 180/110 or greater requires immediate medical attention. If you take this reading two times in a row, five minutes apart, then you must head to the nearest ER,” says Dr. Meier.
Q. When I am monitoring my blood pressure, which number is most important — top, bottom, or both? A. While both numbers in a blood pressure reading are essential for diagnosing and treating high blood pressure, doctors primarily focus on the top number, also known as systolic pressure.
