Pulse pressure (the difference between systolic and diastolic blood pressure) is frequently increased in older people with hypertension. This can mean that systolic pressure is abnormally high, but diastolic pressure may be normal or low a condition termed isolated systolic hypertension.[59] The high pulse pressure in elderly people with hypertension or isolated systolic hypertension is explained by increased arterial stiffness, which typically accompanies aging and may be exacerbated by high blood pressure.[60]
In hypertensive emergency, there is evidence of direct damage to one or more organs.[27][28] The most affected organs include the brain, kidney, heart and lungs, producing symptoms which may include confusion, drowsiness, chest pain and breathlessness.[26] In hypertensive emergency, the blood pressure must be reduced more rapidly to stop ongoing organ damage,[26] however, there is a lack of randomized controlled trial evidence for this approach.[28]
The pulse pressure is a consequence of the pulsatile nature of the cardiac output, i.e. the heartbeat. The magnitude of the pulse pressure is usually attributed to the interaction of the stroke volume of the heart, the compliance (ability to expand) of the arterial system—largely attributable to the aorta and large elastic arteries—and the resistance to flow in the arterial tree.[66]

Blood pressure is given as a reading of two numbers, such as 110/70. The higher number (systolic) is the pressure when the heart beats. The diastolic, or lower number shows the pressure between the heartbeats, while the relaxed heart is refilling with blood. Normal blood pressure readings are lower than 120/80. The cause of most hypertension is unknown. Occasionally, conditions of the kidney or adrenal gland are the cause of high blood pressure.
Various other factors, such as age and sex, also influence a person's blood pressure. Differences between left and right arm blood pressure measurements tend to be small. However, occasionally there is a consistent difference greater than 10 mmHg which may need further investigation, e.g. for peripheral arterial disease or obstructive arterial disease.[19][20][21]
There have been a significant number of studies on metformin’s risk of inducing lactic acidosis — a state in which lactic acid builds up in the body, which can be fatal. But the greater majority of studies concluded without any cases of lactic acidosis according to “The Phantom of Lactic Acidosis due to Metformin in Patients With Diabetes” in the American Diabetes Association’s (ADA) Diabetes Care journal.
Broad interest in metformin was not rekindled until the withdrawal of the other biguanides in the 1970s. Metformin was approved in Canada in 1972,[128] but did not receive approval by the U.S. Food and Drug Administration (FDA) for type 2 diabetes until 1994.[129] Produced under license by Bristol-Myers Squibb, Glucophage was the first branded formulation of metformin to be marketed in the U.S., beginning on March 3, 1995.[130] Generic formulations are now available in several countries, and metformin is believed to have become the world's most widely prescribed antidiabetic medication.[126]
Recognizing heart attack symptoms and signs can help save your life or that of someone you love. Some heart attack symptoms, including left arm pain and chest pain, are well known but other, more nonspecific symptoms may be associated with a heart attack. Nausea, vomiting, malaise, indigestion, sweating, shortness of breath, and fatigue may signal a heart attack. Heart attack symptoms and signs in women may differ from those in men.
But as many people know, diet and lifestyle change can often be very difficult. Medication is also an option for many people, sometimes because an individual has a difficult time achieving significant lifestyle change, and sometimes because hypertension is severe enough to mandate a combination of lifestyle change with medication. For many, treating their high blood pressure with medication can be a difficult subject-one that should always be considered under the guidance of your doctor.

The new guidelines note that blood pressure should be measured on a regular basis and encourage people to use home blood pressure monitors. Monitors can range from $40 to $100 on average, but your insurance may cover part or all of the cost. Measure your blood pressure a few times a week and see your doctor if you notice any significant changes. Here are some tips on how to choose and use a monitor.

Vitamin B12 is available in several forms. There’s much controversy surrounding which forms of Vitamin B12 are best absorbed by human beings. Manufacturers of each form claim support in the scientific literature for their form. But, something else seems to matter more.  If you have a clear deficiency (identified with an inexpensive blood test), you need upwards of 1000mcg to quickly shore up your Vitamin B12 levels.

First-line medications for hypertension include thiazide-diuretics, calcium channel blockers, angiotensin converting enzyme inhibitors (ACE inhibitors), and angiotensin receptor blockers (ARBs).[13] These medications may be used alone or in combination (ACE inhibitors and ARBs are not recommended for use in combination); the latter option may serve to minimize counter-regulatory mechanisms that act to restore blood pressure values to pre-treatment levels.[13][129] Most people require more than one medication to control their hypertension.[111] Medications for blood pressure control should be implemented by a stepped care approach when target levels are not reached.[128]
Blood pressure is expressed by two measurements, the systolic and diastolic pressures, which are the maximum and minimum pressures, respectively.[1] For most adults, normal blood pressure at rest is within the range of 100–130 millimeters mercury (mmHg) systolic and 60–80 mmHg diastolic.[7][12] For most adults, high blood pressure is present if the resting blood pressure is persistently at or above 130/80 or 140/90 mmHg.[5][7] Different numbers apply to children.[13] Ambulatory blood pressure monitoring over a 24-hour period appears more accurate than office-based blood pressure measurement.[5][10]
Resistant hypertension is defined as high blood pressure that remains above a target level, in spite of being prescribed three or more antihypertensive drugs simultaneously with different mechanisms of action.[131] Failing to take the prescribed drugs, is an important cause of resistant hypertension.[132] Resistant hypertension may also result from chronically high activity of the autonomic nervous system, an effect known as "neurogenic hypertension".[133] Electrical therapies that stimulate the baroreflex are being studied as an option for lowering blood pressure in people in this situation.[134]

For example, a 2015 study known as the SPRINT trial found that patients who lowered their systolic blood pressure to around 120 mm Hg were 27 percent less likely to die during the study period, compared with those whose treatment target was to lower their blood pressure to less than 140 mm Hg. (The SPRINT study made headlines in 2015 when the trial was abruptly cut short because the findings were so significant.)
It’s important to determine whether your low blood pressure is “a primary problem or secondary problem,” notes Lawrence. A primary problem means that the body’s reflexes are not working as they should. Secondary causes mean that the low blood pressure is a result of things like dehydration or the effects of certain medications. “Some anti-hypertensive [medications] are more likely to cause hypotension than others, and a lot of it is dose-dependent,” says Lawrence. “In most people, there will be some easily identifiable secondary cause, or some easy solution to what may even be a chronic problem that has no secondary cause, and that’s why it’s important to see your doctor, so they can make an appropriate assessment.”
Interest in metformin resumed at the end of the 1940s. In 1950, metformin, unlike some other similar compounds, was found not to decrease blood pressure and heart rate in animals.[120] That year, Filipino physician Eusebio Y. Garcia[121] used metformin (he named it Fluamine) to treat influenza; he noted the medication "lowered the blood sugar to minimum physiological limit" and was not toxic. Garcia believed metformin to have bacteriostatic, antiviral, antimalarial, antipyretic and analgesic actions.[122] In a series of articles in 1954, Polish pharmacologist Janusz Supniewski[123] was unable to confirm most of these effects, including lowered blood sugar. Instead he observed antiviral effects in humans.[124][125]
It is usually only when a person is in the midst of what is known as a hypertensive crisis — a period of extremely high blood pressure with a reading of 180/120 millimeters of mercury (mm Hg) or higher — that she or he will experience symptoms, such as a headache. This is considered a medical crisis, and if it occurs, you should call 911 and get emergency help.

It has been shown that meditation and other relaxation techniques can help lower blood pressure. Yoga, tai chi, and breathing exercises can also help reduce blood pressure. It's best when these are combined with changes in diet and exercise. Tell your doctor if you are taking any herbal remedies, since some of these preparations can actually raise blood pressure or interact with your blood pressure medications. The following are supplements that may lower blood pressure:
In type 2 diabetes the cells in the body, particularly muscle, fat and liver cells, become resistant to the action of insulin. Insulin is the main hormone responsible for controlling the level of sugar (glucose) in the blood. It makes cells in the body remove sugar from the blood. When the cells are resistant to insulin this makes blood sugar levels rise too high.

2. Take the right nutrients. Talk with your chiropractor or other healthcare professional about the wide range of well-studied nutrients that, along with dietary and lifestyle modifications, can help normalize your blood pressure. One meta-analysis found magnesium supplements could lower blood pressure. Likewise, researchers find a small but significant decline in blood pressure for people with hypertension who use fish oil. (You can get all of fish oil’s benefits combined with anti-inflammatory flax oil and GLA in our Optimal Omega.)

Echocardiogram is an ultrasound examination of the heart It is used to evaluate the anatomy and the function of the heart. A cardiologist is required to interpret this test and can evaluate the heart muscle and determine how thick it is, whether it moves appropriately, and how efficiently it can push blood out to the rest of the body. The echocardiogram can also assess heart valves, looking for narrowing (stenosis) and leaking (insufficiency or regurgitation). A chest X-ray may be used as a screening test to look for heart size, the shape of the aorta, and to assess the lungs.
As you get older, high blood pressure, especially isolated systolic hypertension, is more common and can increase your risk of serious health problems. Treatment, especially if you have other medical conditions, requires ongoing evaluation and discussions with your doctor to strike the best balance of reducing risks and maintaining a good quality of life.
Enlarged heart. High blood pressure increases the amount of work for your heart. Like any heavily exercised muscle in your body, your heart grows bigger (enlarges) to handle the extra workload. The bigger your heart is, the more it demands oxygen-rich blood but the less able it is to maintain proper blood flow. As a result, you feel weak and tired and are not able to exercise or perform physical activities. Without treatment, your heart failure will only get worse.
While high blood pressure doesn’t have any distinctive symptoms in itself, there can be many associated conditions and signs that high blood pressure may be affecting your body and causing damage. When left untreated, high blood pressure can cause the following symptoms in the body, which may worsen over time. If you are experiencing any of the following symptoms chances are your high blood pressure may be placing you at risk of developing further conditions and should be addressed immediately.
3. Fairly recently, the difference between Systolic and Diastolic pressure, named "Pulse Pressure", has been gaining interest in the research community. This Pulse Pressure has been found to correlate linearly with heart attack risk - the higher the number, the higher the risk. According to this theory, a BP of 140/ 90 (PP=50) is more desirable than a BP of 140/ 80 (PP=60).
