Ongoing blood pressure levels of 120/80 mmHg–140/90 mmHg are a warning sign that you could develop chronic hypertension and increase your risk of stroke.
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).
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. A reading this high is considered “hypertensive crisis.” Readings between 120/80 and 129/89 are considered pre-hypertension.
High blood pressure is a major risk factor for stroke. HBP adds to your heart's workload and damages your arteries and organs over time. Compared to people whose blood pressure is normal, people with HBP are more likely to have a stroke.
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.
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.
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.
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.
Researchers and doctors have known for years that high blood pressure causes strokes. The connection between high blood pressure and strokes is well documented. But did you know that high blood pressure also increases your risk of having a “mini stroke” — and can even lead to other brain disorders like dementia?
If you are monitoring your blood pressure at home and notice levels regularly above 140/90 OR if you are experiencing symptoms such as severe headaches or changes in vision, contact your doctor immediately and go to the emergency room.
High blood pressure, also known as hypertension, is usually defined as having a sustained blood pressure of 140/90mmHg or above. The line between normal and raised blood pressure is not fixed and depends on your individual circumstances.
Call a doctor if:
Your blood pressure is 140/90 or higher on two or more occasions. Your blood pressure is usually normal and well controlled, but it goes above the normal range on more than one occasion.
Ongoing blood pressure levels of 120/80 mmHg–140/90 mmHg are a warning sign that you could develop chronic hypertension and increase your risk of stroke.
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.”
That level should be lower than 120/80 mmHg. When the level stays high, 140/90 mmHg or higher, you have high blood pressure. With high blood pressure, the heart works harder, your arteries take a beating, and your chances of a stroke, heart attack, and kidney problems are greater.
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.
The warning signs of stroke include: Weakness or numbness of the face, arm or leg, usually on one side of the body. Trouble speaking or understanding. Problems with vision, such as dimness or loss of vision in one or both eyes.
The major risk factors for stroke include: High blood pressure. Diabetes. Heart and blood vessel diseases: Conditions that can cause blood clots or other blockages include coronary heart disease, atrial fibrillation, heart valve disease, and carotid artery disease.
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?
Stress can cause the heart to work harder, increase blood pressure, and increase sugar and fat levels in the blood. These things, in turn, can increase the risk of clots forming and travelling to the heart or brain, causing a heart attack or stroke.
If you and your doctor decide that daily aspirin is right for you, your doctor will recommend a dose of aspirin and how often to take it. Low-dose aspirin (81 mg) is the most common dose used to prevent a heart attack or a stroke. A typical schedule is to take aspirin every day.
In general, most experts consider a young stroke age to be under 45. Even though the overall rate of stroke is decreasing, especially in people over age 65, it's actually increasing among young and middle-aged people.
