How Can I Be More Active
- Check first with your healthcare provider before increasing your physical activity. Ask your provider what type and amount of exercise is right for you.
- Choose aerobic activities such as walking, biking or swimming.
- Start slowly and increase activity gradually. Aim for a regular routine of activity five times a week for 30 to 45 minutes each session.
What Do Blood Pressure Numbers Mean
Blood pressure is measured using two numbers:
The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats.
The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.
If the measurement reads 120 systolic and 80 diastolic, you would say, 120 over 80, or write, 120/80 mmHg.
What Does High Blood Pressure Feel Like
High blood pressure often doesn’t have any symptoms, so you usually don’t feel it. Thats why its important to stay up to date on your preventive care screenings can help identify potential problems like elevated blood pressure when its easiest to treat.
If your blood pressure reaches extremely high levels, you may get a headache, shortness of breath or a nosebleed. However, these symptoms may not be specific to your blood pressure. Critically high blood pressure can be caused by conditions that can have similar symptoms, like strokes, heart attacks, heart failure, kidney failure or certain drug interactions.

How High Can Your Bp Go Before Increasing The Risk Of A Stroke
One of the best ways to limit the chance of a stroke is to measure and monitor your blood pressure regularly. If you have a blood monitor at home and have high blood pressure, it’s a good idea to take your pressure readings twice daily.
Health professionals measure blood pressure using systolic and diastolic blood pressure numbers.
Systolic blood pressure is the pressure within your arteries as your heart beats. Normal systolic blood pressure is below or equal to 120 mm Hg.
Diastolic blood pressure measures blood pressure when your heart rests on refilling with blood.
Normal diastolic pressure is lower than or equal to 80 mm Hg.
If you have consistent blood pressure levels over 130/80 mm Hg, that is consistent with hypertension.
Ongoing blood pressure levels of 120/80 mmHg140/90 mmHg are a warning sign that you could develop chronic hypertension and increase your risk of stroke.
A single blood pressure reading is insufficient to diagnose high blood pressure.
You may get anxious in a medical environment, raising your blood pressure. So, your doctor may give you a 24-hour monitor to assist you with tracking your blood pressure.
If you are pregnant, using oral contraception, under hormone replacement therapy , or taking blood pressure medication, get your blood pressure checked regularly.
Association Of Sbp And Dbp With First
The stroke risk was 58% higher among individuals with SBP values of 140159 mmHg than among those with SBP values of < 130 mmHg , after adjusting for age, sex, educational level, BMI, smoking status, and drinking status . Accordingly, the stroke risk increased 1.56-fold among those with SBP values of 160179 mmHg and 2.08-fold among those with SBP values 180 mmHg, compared with the reference group . Similarly, the ischemic stroke risk increased by 60%, 1.67-fold, and 1.4-fold, in the respective groups. However, hemorrhagic stroke risk increased only among participants with SBPs 160 mmHg, with increases of 2.3-fold among those with SBP values of 160179 mmHg and 2.12-fold among those with SBPs 180 mmHg.
Simultaneously, stroke risk increased significantly among participants with DBP values of 90 mmHg compared to the reference group of individuals both in IS and in ICH .

Further, we assessed the SBP and DBP as a continuous variable in Cox proportional hazard model. Each 1 mmHg increasement of SBP resulted in 1.6% increased risk of stroke, 1.3% for IS and 2.0% for ICH. The corresponding value of DBP was 3.0% overall, 2.7% for IS and 3.8% for ICH. Similar trends were found both in men and in women .

Listen to Mau Moananus story and why he urges everyone to get their blood pressure checked regularly:
1 The NZ Health Survey is based on a sample of 13,000 adults, they have not surveyed all New Zealanders and therefore it is only an estimate of the prevalence. Furthermore, the figure is only an estimate of the number of people with hypertension that are medicated, with the latest estimate given at 16.1% of the NZ adult population. So its fair to say we can safely extrapolate that up as there will be a good number of adults who have hypertension but are not medicated, which is how we get to the one in five figure.

Negative Effects Of Uncontrolled High Blood Pressure
The U.S. Centers for Disease Control and Prevention estimates that about one out of every three American adults have high blood pressure, or hypertension. Because high blood pressure is so common, it might be tempting to assume that its no big deal. But the truth is, that when left untreated, high blood pressure can put you at risk for potentially life-threatening complications.
Here are eight ways that uncontrolled high blood pressure can negatively affect your health:
Strategies For Maintaining Safe Blood Pressure
Although some symptoms of unbalanced blood pressure can be quite apparent such as dizziness, chest pain, or shortness of breath many people go a long time without even realizing theyre at risk for blood pressure-related issues.
Many risk factors can be addressed with lifestyle changes. Taking control of yourdiet and exercise routine is one of the most important strategies for balancing your blood pressure. Avoid a diet high in sugar, sodium, saturated fats and cholesterol, and create a simple and enjoyable daily workout routine that fits into your lifestyle. Consistency is key, so be sure to make changes that you can maintain and build upon.
Cigarette smoke, both first and second-hand, can damage the blood vessels. Doctors also advise against more than one or two alcoholic drinks per day at the most, as alcohol can add a dangerous level of artery-hardening triglycerides to your blood.
As some risk factors, such as age, race, or genetics, cannot be eliminated, keeping a close eye on your blood pressure with the help of your doctor is the best defense against stroke. This is especially crucial after experiencing an initial stroke. Both high and low blood pressure increase the risk of recurrent ischemic stroke, and a regular routine of exercise, controlled diet, and taking prescribed medications as recommended by your physician can help offset that risk.

What Is Considered Stroke
Blood pressure readings above 180/120 mmHg are considered stroke-level and dangerously high
A severe increase in blood pressure that can lead to a stroke is called a hypertensive crisis. Extremely high blood pressure can damage blood vessels and weaken arteries in the brain, increasing the risk of stroke.
- Healthy blood pressure: under 120/80 mm Hg
- Prehypertension: 120/80 mm Hg to 139/89 mm Hg
- Hypertension: above 140/90 mm Hg
- Hypertensive crisis: above 180/120 mm Hg
High blood pressure, or hypertension, is the leading cause of strokes in the U.S. However, understanding risk factors and blood pressure readings can help people seek appropriate treatment:
Blood pressure readings above 180/120 mmHg are considered stroke-level, dangerously high and require immediate medical attention.
What are symptoms of high blood pressure?
- Severe Headaches
- Blood spots in eyes
While hypertension is sometimes called the silent killer due to the fact that most people show no symptoms, a few common signs of the condition include:
What are the different types of hypertension?
- Primary hypertension or essential hypertension is the most common type, and there is no known cause for it. This type of high blood pressure usually takes many years to develop is often the result of lifestyle, environment and older age.
- Secondary hypertension is caused by another health problem or medication:
- Kidney problems
- Thyroid or adrenal gland problems
- Side effects of some medications
How Blood Pressure Is Measured
Hypertension can be mild, moderate or severe. Your blood pressure is naturally higher when you are exerting yourself, such as during physical exercise. It is only a concern if your blood pressure is high when you are at rest, because this means your heart is overworked and your arteries have extra stress in their walls.Blood pressure readings are a combination of two measurements. These are:
- Systolic is the highest pressure against the arteries as the heart pumps. The normal systolic pressure is usually between 110 and 130mmHg.
- Diastolic is the pressure against the arteries as the heart relaxes and fills with blood. The normal diastolic pressure is usually between 70 and 80mmHg.
Other Types Of Medication
Beta-blockers work by making your heart beat more slowly and with less force, which reduces your blood pressure. They are usually only recommended if other treatments havent worked, because they are less effective than other treatments on their own.
It is important that you do not suddenly stop taking this type of medication without seeking medical advice first.
Examples of beta-blockers include labetalol, atenolol, and bisoprolol.
Possible side effects include slowing of the heart rate, cold fingers and toes, nausea, diarrhoea, tiredness and sleep problems. It can make asthma worse, or affect your breathing if you have heart failure.
Other medication groups
Other medications that may be used to control blood pressure include doxazosin and terazosin , and clonidine and methyldopa . Another type of diuretic called spironolactone can also be used at low doses. These medications are only usually recommended if other treatments have not worked.

What Causes A Stroke
A stroke is caused when blood flow to your brain is stopped or disrupted.
There are 2 kinds of stroke: ischemic and hemorrhagic.
Ischemic stroke. This is the most common type of stroke. It happens when a major blood vessel in the brain is blocked. It may be blocked by a blood clot. Or it may be blocked by a buildup of fatty deposit and cholesterol. This buildup is called plaque.
Hemorrhagic stroke. This occurs when a blood vessel in your brain bursts, spilling blood into nearby tissues. With a hemorrhagic stroke, pressure builds up in the nearby brain tissue. This causes even more damage and irritation.

Prehypertension: A Little Too Much Pressure A Lot Of Trouble
Everyone needs some blood pressure so that blood can get to all of the bodys organs. But how much is enough? How much is too much?
High blood pressure is often called the silent killer, because it usually doesnt cause symptoms. High blood pressure is also known as hypertension. It points to a higher risk of having heart disease, kidney disease and stroke. Doctors have known for a long time that blood pressure that is too high can cause these problems. But now doctors know that if it is even a little too high, it should be noticed.
When you visit a doctor for your annual checkup, your blood pressure will be taken. Blood pressure is measured by a machine with a band wrapped around your arm. The measure will tell if the blood pressure is normal, low, high, or somewhere in between. It is considered prehypertension when it doesnt quite reach the level of high blood pressure, but it is higher than normal.
Prehypertension can serve as an early warning for patients and doctors. It is a sign of possible changes that could lead to heart disease. The pressure caused by constant prehypertension can change blood vessels and the heart in a damaging way. Prehypertension can also stress the kidneys.
A single blood pressure reading does not predict heart and blood vessel disease . You wont be diagnosed with hypertension or prehypertension until it is high on several occasions. A blood pressure reading higher than normal will need to be carefully monitored.

Lowering Systolic Blood Pressure More May Cut Health Risks
One major study found that lowering systolic blood pressure to well below the commonly recommended level also greatly lowered the number of cardiovascular events and deaths among people at least 50 years old with high blood pressure.
When study participants achieved a systolic blood pressure target of 120 mmHg compared to the higher target of 140 mmHg recommended for most people, and 150 for people over 60 issues such as heart attack, stroke and heart failure were reduced by almost one-third, and the risk of death by almost one-fourth.
“That’s important information, because more lives may be saved and more deaths may be prevented if we maintain lower blood pressure in certain patients,” says Lynne Braun, NP, PhD, a nurse practitioner at the Rush Heart Center for Women.
Braun cautions, however, that your personal blood pressure target depends on a variety of things, including your current blood pressure, lifestyle, risk factors, other medications you are taking and your age. “Every person has to be evaluated as an individual,” she says. “Realistically, we can’t get everybody down to 120, and trying to do so may create unintended problems.”
It can be dangerous, for instance, to keep an older person on medications that have unsafe side effects, such as diuretics , which can cause dehydration and dizziness in older adults.
And there can be other issues involved with taking multiple medications, such as cost and compliance.
Blood Pressure Management In Hypertensive Emergencies Involving Brain Damage
BP management in hypertensive emergencies involving brain damage should consider that the pathophysiology of brain damage is unique to each condition. Management should be tailored according to the disease and there is not a single recommendation that fits all. Consequently, the right diagnosis is crucial based upon clinical features, brain imaging, neurovascular evaluations and cardiac tests.

Salt Intake And Stroke
High salt intake, measured as 24-h urinary sodium excretion, increases the risk of cardiovascular disease, mainly stroke . The same can be seen in individuals with chronic kidney disease, for which the risk of stroke increases linearly when urinary sodium excretion increases . A majority of our participants, 61%, with stroke had impaired kidney function, defined as diabetic nephropathy. Yet, we did not find any associations with urinary sodium and potassium excretion and stroke. One possibility for this result could be the low number of individuals tested we only had information on urinary sodium and potassium excretion available for 115 participants with stroke. Many of these individuals also had micro- or macroalbuminuria, which in some part affect the urinary excretion. On the other hand, no trends towards any associations were seen in the analyses.
Bp Lowering In Previously Hypertensive Patients
As many patients who present with IS have already been on antihypertensive therapy yet have persistently elevated BP levels, an obvious question is whether to continue such treatment and/or introduce more aggressive BP lowering. However, observational data indicate that chronically hypertensive patients appear to have their cerebral autoregulation shifted to a higher level, which could potentially make rapid BP lowering more hazardous as cerebral perfusion is more directly related to systemic BP . However, the SITS-ISTR database suggests that withholding antihypertensive therapy in such patients is associated with higher risks of symptomatic ICH, death and dependency . Although terminated early due to poor recruitment, the Continue Or Stop post-Stroke Antihypertensives Collaborative randomised controlled Study in 763 patients gives us some guidance about whether to continue or stop usual antihypertensive therapy within 48 hours of suspected stroke . In this study, where the mean BP difference between the continue and stop randomised groups was 13/8 mmHg at 2 weeks, there were no beneficial effects.
