Studies Addressing Whether Low Dbp Related To Worse Prognosis In Sh Is A High
As early as 1978, Anderson noted that, in the Framingham Heart Study data, when treating HTN, the benefit of sBP decrease was linear and continuous . Indeed, this is a motivation to further decrease sBP to lower values. In contrast, no importance was placed on diminishing dBP below approximately 90 mm Hg . This absence of an additional benefit of progressive dBP decrease explains, at least in part, a very important fact, i.e., why sBP has a more significant prognostic influence than dBP does. Subsequently, in 1979, Stewart demonstrated a > 5-fold increased mortality rate from MI associated with an excessive dBP decrease induced by drug treatment . The BP J-shaped curve debate started 40 years ago, and there is no indication that it will end in the near future. The J-shaped/U-shaped curve means that, for example, mortality is lower at the nadir and that both higher and lower values are associated with higher mortality.
In the vast majority of studies, the univariate association of low dBP with worse prognosis has been proved. In many studies, multivariate analysis is missing in others, results are conflicting regarding this J-curve relationship. Here, we analyze several important studies.
Heart Attack And Heart Disease
High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause:
- Chest pain, also called angina.
- Heart attack, which happens when the blood supply to your heart is blocked and heart muscle begins to die without enough oxygen. The longer the blood flow is blocked, the greater the damage to the heart.
- Heart failure, a condition that means your heart cant pump enough blood and oxygen to your other organs.
This Daily Breathing Exercise Works As Well As Medicine To Reduce High Blood Pressure
Did you know daily breath exercise can work as well as medicine to reduce high blood pressure?
There is mounting evidence that suggests that strengthening the muscles used in breathing can be just as beneficial and vital.
New studies show that daily training for the diaphragm and other breathing muscles can help support heart health.
It can also help lower high blood pressure.
Blood pressure, pulse, respiration rate, and temperature are considered the 4 main vital signs. These simple measurements can tell us a lot about how healthy we are.
Blood pressure, in particular, can be a strong indicator of wellness. BP readings can even indicate whether or not were likely to have a heart attack or stroke.
For this reason, researchers are constantly on the hunt for ways to decrease high blood pressure in patients.
Recently, a group developed a product called PowerBreathe.
PowerBreathe is a small, roughly inhaler-sized product that provides resistance to the patients breath.
Interestingly, regular training with this device has been associated with a decrease in blood pressure.
In this article, well take a look at how breath training with devices such as PowerBreathe can be effective in reducing blood pressure.

Why Your Blood Pressure Matters
When the heart beats, blood pulses through the arteries to travel throughout the body. However, it is not a steady stream like you might see from a garden hose.
The pulse of the blood flow and the pressure it exerts change from moment to moment. It’s highest during the heartbeat and lowest between heartbeats .
Providers measure blood pressure using these numbers because it is a standard way of describing the force of the pulsing blood.
Your systolic and diastolic blood pressures are both important. If the readings are too high, you could have high blood pressure. If the readings are too low, there may not be enough blood flowing to your brain and other organs.
Furthermore, if there are changes in the difference between the two numbers, it’s a clue that there could be a heart condition or other health problem.

Do I Have High Blood Pressure
Anyone can have high blood pressure. Some medical conditions, such as metabolic syndrome, kidney disease, and thyroid problems, can cause high blood pressure. Some people have a greater chance of having it because of things they can’t change. These include:
- Age. The chance of having high blood pressure increases as you get older, especially isolated systolic hypertension.
- Gender. Before age 55, men have a greater chance of having high blood pressure. Women are more likely to have high blood pressure after menopause.
- Family history. High blood pressure runs in some families.
- Race. African Americans are at increased risk for high blood pressure.
High blood pressure often has no signs or symptoms, but routine checks of your blood pressure will help detect increasing levels. If your blood pressure reading is high at two or more check-ups, the doctor may also ask you to measure your blood pressure at home.
There are important considerations for older adults in deciding whether to start treatment for high blood pressure, including other health conditions and overall fitness. Your doctor will work with you to find a blood pressure target that is best for your well-being and may suggest exercise, changes in your diet, and medications.
When Should You See A Doctor
Early high blood pressure detection is essential. This silent killer often shows no warning signs and therefore puts people at a higher risk of conditions such as:
Over 360,000 high-blood-pressure deaths occurred in 2016 in the US, whether hypertension was a contributing cause or the main cause.¹²
The only way to identify if you have high blood pressure is to measure it. You can visit your healthcare provider for regular blood pressure monitoring, or you can purchase a sphygmomanometer to measure your blood pressure at home.
If you’re at risk of high blood pressure, you need to schedule routine healthcare visits to monitor your blood pressure. You should also see your healthcare provider if you have high blood pressure and your efforts to reduce your blood pressure have been ineffective.

Different Types Of Blood Pressure Medications
There are many types of blood pressure medications, each with its own set of benefits and drawbacks. Some of the most common types include:Angiotensin-converting enzyme inhibitors : These medications block the activity of angiotensin II, a hormone that raises blood pressure. ACE inhibitors are typically the first choice for people with hypertension who dont respond well to other drugs. Theyre also a good option for people who have heart disease due to their ability to improve heart function and reduce the risk of stroke. Side effects include dry mouth, dizziness, and headache.Angiotensin receptor blockers : Like ACE inhibitors, ARBs block the activity of angiotensin II. But they work in a different way: by preventing the receptor from being able to activate other hormones that increase blood pressure. ARBs are generally less powerful than ACE inhibitors, but they have fewer side effects and are sometimes preferred by people who cant take ACE inhibitors because they have heart disease or diabetes.Calcium channel blockers : CCBs help keeps blood vessels flexible by blocking calcium channels in the cells that line them.
What Does It Mean If My Diastolic Blood Pressure Is High
When your diastolic blood pressure is over 90mm Hg, it’s often called diastolic hypertension. The diastolic pressure of an adult should typically be 6080mm Hg, and if the number goes above this, it’s considered hypertension.
However, if your blood pressure goes over 180/120mm Hg, this is dangerous, and you should seek medical attention immediately.
High diastolic blood pressure has been associated with a few conditions, including:
Abdominal aortic aneurysm
High diastolic blood pressure has been associated with a higher risk of conditions that involve the aorta that carries oxygen and blood from your heart to your chest and abdomen.
For instance, individuals with an elevated diastolic blood pressure reading were more susceptible to developing an abdominal aortic aneurysm. This is an abnormal enlargement of your aorta and can result in rupture and risk of death.
Several studies show that elevated diastolic blood pressure seems to be linked with memory deficits or cognitive impairment in individuals aged 45 or older. For every 10-point increase above 90mm Hg, it increases the risk of cognition issues by 7%.¹
While there isn’t an established causal relationship, treating or preventing high blood pressure may prevent cognitive impairment.
Stroke and brain issues
A diastolic blood pressure of 100mm Hg or above is linked with a substantial rate of strokes.¹ High blood pressure can lead to your arteries becoming blocked or bursting, causing a stroke.

Diastolic Blood Pressure: How Low Is Too Low
Blood pressure consists of two numbers. Systolic pressure, the force exerted on blood vessels when the heart beats, is the upper number. Diastolic pressure, the force exerted when the heart is at rest, is on the bottom in more ways than one. Systolic pressure attracts the lions share of attention from physicians and patients, says UAB cardiologist Jason Guichard, M.D., Ph.D.
Physicians are busy people, and like it or not they often focus on a single number, Guichard said. Systolic blood pressure is the focus, and diastolic pressure is almost completely ignored. That is a mistake, he argues. The majority of your arteries feed your organs during systole. But your coronary arteries are different they are surrounding the aortic valve, so they get blood only when the aortic valve closes and that happens in diastole.
Diastolic pressure has been getting more attention lately, however, thanks in part to an influential paper in Hypertension, written in 2011 by Guichard and Ali Ahmed, M.D., then a professor of medicine in UABs Division of Gerontology, Geriatrics and Palliative Care and now the associate chief of staff for Health and Aging at the Veterans Affairs Medical Center in Washington, D.C.
Most people are trying to lower their blood pressure. What would you define as too low, and why is that a problem?
Disease Prevention Through Breath Training
Not only can breathing exercise reduce the severity of hypertension, it might also prevent it from ever occurring.
Some researchers postulate that breath training can have similar physiologic effects as aerobic exercise.
At this time, the data does not currently provide strong support for this claim. However, it stands to reason that strengthening these muscles can be a preventative step for the development of hypertension.
It should be said, however, that aerobic exercise has many other benefits. For example, walking or biking can also improve muscular endurance and strength throughout the body.
So, we dont want to imply that breath training should replace aerobic exercise. Rather, it could be used in conjunction with this type of workout.

What Are The Treatments For High Blood Pressure
You will work with your provider to come up with a treatment plan. It may include only the lifestyle changes. These changes, such as heart-healthy eating and exercise, can be very effective. But sometimes the changes do not control or lower your high blood pressure. Then you may need to take medicine. There are different types of blood pressure medicines. Some people need to take more than one type.
If your high blood pressure is caused by another medical condition or medicine, treating that condition or stopping the medicine may lower your blood pressure.

How Is It Treated
If your systolic blood pressure is too high, your doctor may prescribe medicine to help bring it down. Drugs used to control blood pressure include:
- Diuretics to help your kidneys flush water and sodium from your body
- Beta-blockers to make your heart beat slower and less forcefully
- Angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers , or calcium channel blockers to relax your blood vessels
- Renin inhibitors to keep your kidneys from making a chemical that can lead to higher blood pressure
Your doctor also may recommend you do a few other things:
- If you smoke, stop. There are lots of good reasons for this, but nicotine in cigarette smoke can raise your blood pressure.
- Lower the amount of salt in your diet.
- Cut back on alcohol if you drink.
- Get to or stay at a healthy weight.

Prevention And Management Of Low Diastolic Blood Pressure
There are some things you can do to help prevent and manage low diastolic pressure:
- Try to keep your salt intake to between 1.5 and 4 grams per day. An ideal number is about 3.5 grams. Read food labels to avoid added salt in your diet.
- Eat a heart-healthy diet. This diet includes plenty of fruits, vegetables, and whole grains. For protein, stick to lean meats and fish. Avoid fatty foods.
- Drink enough fluids and avoid alcohol, which can increase your risk of dehydration.
- Stay physically active and start an exercise program. Ask your doctor what type and amount of exercise is safe for you.
- Maintain a moderate weight. If youre overweight, your doctor can help you create a safe weight loss plan.
- If you smoke, quit. Quitting can be difficult, so consider reaching out for support.
Causes Of Diastolic Hypotension By Itself
There are three known causes of isolated diastolic hypotension:
- Alpha-blocker medications. These blood pressure medications work by causing your blood vessels to open up . Because they lower diastolic pressure more than systolic pressure, they may cause isolated diastolic hypotension. Common brand names include Minipress and Cardura.
- Aging. As we age, we lose the elasticity of our arteries. For some older adults, arteries may become too stiff to spring back between heartbeats, causing diastolic blood pressure to be low.

What Is Diastolic Blood Pressure
Your blood pressure reading has two numbers. The top one is systolic pressure the force your heart uses to pump blood out to your body. The bottom, lower number is diastolic pressure the pressure in your blood vessels between beats.
Typically, people are more interested in the top number, systolic blood pressure. Isolated systolic hypertension when the top number is elevated and the bottom one is normal is actually the most common type of high blood pressure in people aged 65 and over. It also carries a greater risk of stroke and heart disease than elevated diastolic blood pressure, especially in people over 50.
However, we now know that both numbers are important, and either an elevated systolic or diastolic blood pressure reading may be used to diagnose high blood pressure.
Heres how to understand your diastolic blood pressure number:

Can You Prevent It
Surely, you dont want to experience any of the conditions abovementioned. That is why the saying, Prevention is better than cure holds true for this kind of condition.
Fortunately, you can prevent high systolic low diastolic readings with the help of the following tips and tricks:
Regularly monitor your blood pressure to help you check whether both systolic and diastolic are within the normal range.
Avoid smoking and drinking alcohol
Maintain a healthy weight
Minimize your salt intake
Treat blood pressure-related conditions on the onset before it gets worse
The bottom line is to get treatment as soon as you can and dont wait for your condition to get worse. If you suspect that something is wrong with your body, it is best to consult a doctor for proper diagnosis. Consequently, he could prescribe medications and advice you to do certain things to normalize your blood pressure levels.
Dont self-diagnose. Blood pressure issues are no laughing matter. If you are not too careful, the worst that could happen is death.
