Ambulatory Blood Pressure Characteristics And Msbp
At least two thirds of the blood pressure readings were successful for all participants, thus meeting the minimum requirements for ambulatory blood pressure recordings . None of the participants reported severely disrupted sleep. The mean number of blood pressure recordings over the 24 h period, during sleep and during wake were 61 ± 1 , 16 ± 1 , and 44 ± 1 , respectively. The average time of going to sleep was 23:43 h and the average time of rising was 07:28 h . The mean hours of sleep was 8.2 ± 2.2 h. Mean values for systolic BP, diastolic BP, MAP, and heart rate over 24 h and during sleep and times of wakefulness are displayed in Table 1. All cardiovascular variables were significantly lower during sleep than wakefulness . The mean MSBP values are displayed in Table 2. Linear regression analyses revealed no significant relationships between BRS and blood pressure averaged over the 24-h recording period, wakefulness or sleep .

Strokes And Coronary Artery Disease
In one study, high morning BP has been shown as a strong predictor of coronary artery disease and strokes. After researching over 20,000 people with high blood pressure, the number of strokes was significantly higher in people with morning systolic blood pressure equal to or over 145 mmHg when compared to people with less than 125 mmHg.
In addition, the same research found the amount of coronary artery disease was significantly higher in people with the higher systolic blood pressure in the morning 22.
What Happens If You Have Morning Hypertension
If you have hypertension, specifically morning hypertension, you have a stronger risk of stroke compared to others with hypertension but not in the morning.
is able to cause a stroke, or a sudden loss of brain function because of a lack of supply of blood to the brain. Morning hypertension can also raise your risk of other blood vessel and heart problems. Changes in your heartys size and rhythm have been associated with it, and this can lead to heart failure or a heart attack. Speak with your doctor right away if you go through any symptoms such as chest pain, severe headache or numbness in your arms or face.

Hypertensionblood Pressure Morning Surge
In Malaysia, 1 in 3 adults suffers from high blood pressure. Of every 5 high blood pressure patients, 3 are not aware that they are hypertensive patients.
Human blood pressure changes with activities. Normally, after waking up, blood pressure will rise rapidly to support our days activities. This is called blood pressure morning surge phenomenon. After the night falls, blood pressure will decline slowly due to reduced activity.
However, between 6:00 am and 12:00 noon, when blood pressure increases beyond 135/85 mmHg, it will increase the risk of cardiovascular disease such as stroke, heart attack, and even sudden death. To those hypertensive patients, this is undoubtedly being a ticking time bomb!
The public is quite familiar with the symptoms and consequences of hypertension. However, they might not familiar with blood pressure morning surge phenomenon. In fact, blood pressure morning surge is a normal physiological reaction. Between 6 am and 12:00 noon, blood pressure must rise, otherwise we will not able to wake up, work, etc.
However, to hypertensive patients, if the starting point of their blood pressures are already high at the outset, coupled with blood pressure surges, obviously their blood pressure can rise higher than the average person, which will increase the risks of heart attacks and strokes as well as sudden death in the morning.
Stroke Crisis Is As High As 51%
Many stroke cases occur in the morning, which is very likely due to the sudden increase of blood pressure after waking up.
According to studies, blood pressure morning surge phenomenon can well revealing stroke crisis. In Malaysia, up to 51% of stroke victims are suffering from high blood pressure, and the current stroke is also considered the second biggest killer in Malaysia.
Strokes may cause patients to become hemiplegia and lose their language abilities. Some patients may even commit suicides. The affected people are not only confined to patients themselves alone, the negative impacts also involving family members who must take care and help patients recovering from stroke complications.
Once patients have discovered their symptoms of stroke, they should not hesitate to go to hospitals and seek for treatments immediately. If patients conditions are not serious, medicines can help to reduce the damages of strokes, and maintain the patients ability to act independently in future.
At present, at least 970 million people in the world suffer from high blood pressure, and the annual deaths caused by high blood pressure is as high as 9.4 million, which is also identified as an important culprit of early deaths.
Hypertension is called an invisible killer because it usually does not show any obvious symptoms. Only when the systolic blood pressure reaching as high as 180 to 200 mmHg, hypertensive patients start feeling some discomforts.

Sleep And Morning Blood Pressure: What’s The Connection
Sleep and morning blood pressure may also be linked, says Vijay Nambi, MD, associate professor of medicine, Baylor College of Medicine, Houston.
“If you don’t get a good night’s sleep, your blood pressure will be higher,” Dr. Nambi says.
Getting better sleep starts with setting and sticking to wake and bedtime schedules, creating a cool and dark bedroom environment, and avoiding stressful activities before bed, according to the National Sleep Foundation. It’s also important to limit caffeine later in the day as that can keep you awake, and use your bed only for sleep and sex.
In addition, sleep apnea, which is marked by pauses in breathing while sleeping, can cause high blood pressure. When pauses in breathing occur, oxygen levels go down, which may lead to an increase in blood pressure. Treating underlying sleep apnea may improve fatigue and lower your blood pressure levels, Dr. Nambi says.
A continuous positive airway pressure device that administers air pressure through your nose while you’re asleep can treat sleep apnea. If you think you have sleep apnea or your partner constantly complains about your snoringa symptom of sleep apneatalk to your doctor about the next steps.
Latest High Blood Pressure News
If your blood pressure changes a lot overnight — either rising or falling — you may have an increased risk of heart disease and stroke, a new study from Japan reports.
When systolic blood pressure jumps up by 20 mm/Hg or more during the night, the risk of heart disease and stroke goes up by 18% and the risk of heart failure increases by 25%.
If people consistently had higher blood pressure readings at night, but normal readings during the day, the risk of heart failure more than doubled. The researchers, writing in the journal Circulation, dubbed this a “riser pattern.”
On the other hand, for people with a drop in blood pressure of more than 20%, the study team noted a more than twice the risk of stroke. They called this group “extreme dippers.”
“Nighttime blood pressure is increasingly being recognized as a predictor of cardiovascular risk,” study lead author Dr. Kazuomi Kario said in a journal news release. He’s chair of cardiovascular medicine at the Jichi Medical University in Tochigi, Japan.
Dr. Raymond Townsend, an expert volunteer for the American Heart Association, said blood pressure is typically higher in the morning and lower in the afternoon and evening.
Compared to the overall daytime blood pressure pattern, “blood pressure is generally about 10% to 20% lower during sleep. Sleep time offers a relatively pure look at blood pressure. Most factors that influence blood pressure are minimized during sleep,” he explained.

What Are The Consequences Of Morning Hypertension
Those with morning hypertension have a higher risk for heart attack, stroke and sudden death in the first few hours of the morning compared with those without morning hypertension.
If you experience symptoms such as severe headache, chest pain, and numbness or tingling in your face or arms, be sure to contact your doctor immediately.
How High Blood Pressure In The Morning Is Diagnosed
There are a few common ways a doctor will make a diagnosis. The first one is by checking your blood pressure. Your doctor will also examine any home blood pressure measurements you have taken and recorded. If you dont have a home monitor, or want to update the one you have to a better quality, check out this affordable one I recommend in my blog post by clicking here, Upper Arm Monitor. The manufacturer is used by most hospitals and medical centers and they make a great home monitor.
Next, your doctor may recommend 24-hour ambulatory blood pressure monitoring . ABPM involves being outfitted with a device that takes continuous blood pressure readings all day and evening 21. It can be set to measure your BP every 30 minutes or whatever the doctor prefers. ABPM will indicate your exact pressure during the morning hours.
In addition to a physical exam, the following tests may be performed:
- Blood test
- Ultrasound

Sympathetic Neural Control Of Blood Pressure In The Morning
There are some studies focusing on the circadian pattern of cardiovagal BRS. All of them demonstrated that a reduction of cardiovagal BRS occurred concomitant with BP increase in the morning, and it was suggested that cardiovagal BRS may be one of the determining factors for morning surge . Given the fact that a reduction of cardiovagal BRS and its correlation with morning BP was also observed in healthy normotensive subjects and that this relationship disappeared in hypertensive seniors in the current study, cardiovagal BRS may not be a predominant factor for morning BP increase in elderly hypertensive subjects. Indeed, multiple regression analysis showed that the lower cardiovagal BRS tended to be the factor for the higher morning surge in normotensive subjects, but not in elderly hypertensive subjects whose morning surge was significantly impacted by sympathetic BRS.
Central Pulse Wave Velocity
Central aorto-femoral PWV measurements were performed by the same two operators , in a quiet air-conditioned room after 10min of rest and with the subject lying supine. Continuous pulse pressure wave signals were recorded with hand-held tonometers positioned at the base of the right common carotid artery and over the right common femoral artery. Transit distance was defined as the measured distance from the sternal notch to femoral artery minus distance from sternal notch to carotid. The start of systole was defined by the local maximum of the first derivative of the pressure signal. Mean transit time between the feet of simultaneously recorded waves was determined from 10 consecutive cardiac cycles. Mean arterial pressure was estimated from an oscillometric blood pressure measurement taken immediately post recording of the arterial waveforms.

Irregular Blood Pressure Readings
If 120/80 mm Hg is a regular blood pressure, then it can be assumed that anything lower or higher is then irregular. Blood pressure at or above 120/80 and lower than 140/90 is considered normal to high blood pressure.
Hypertension
When your blood pressure is above 140/90, it means that your heart is working too hard and will stress itself out with all the work that it is doing. Hypertension simply means high blood pressure and it is when a lot of your blood is being pumped through slender arteries, causing a lot of pressure and unnecessary stress on your artery walls. This stress can result in health problems.
Hypotension
Hypotension, while maybe thought to be your blood pressure readings below 120/80, is actually your blood pressure readings of 90/60. This is shockingly low and can be shown through dizziness, fainting, and shock. Low blood pressure shows that not enough blood is pumping through to your arteries and that could result in a numerous amount of other problems.
Discover Why Morning Stress Can Be A Cause For High Blood Pressureand Raise Your Risk Of A Heart Attack
Recently, a reader wrote to say, Ive had high blood pressure for two years, but mostly in the morning when it is around 160/80, while at night it goes down to 100/50 sometimes. I am not taking any conventional medicine. My question is whether there is a cause for high blood pressure in the morningand why would it fluctuate so much within seven to eight hours from night to morning?
I know many of you experience high blood pressure in the morning, myself included. It’s normal to have slightly higher blood pressure numbers in the morning, and heres why it happens. Serum cortisol, which activates the autonomic nervous system and can be a cause for high blood pressure, peaks in the early morning hours. This could be why there is a higher risk of a heart attack in the morning. Ask your doctor to check your levels with a 24-hour salivary cortisol test .

Abstract
1. Introduction
Home blood pressure monitoring is well accepted among patients and has been recognized as superior to conventional blood pressure measurements in terms of refining hypertension diagnosis and control . It shows good reproducibility , ensured by blood pressure averages based on several readings performed over multiple days. In addition, it avoids white-coat effect, is free from observer dilution bias, and, compared to office BP, offers better prognostic value in predicting mortality and cardiovascular events .
There are diurnal variations in HBPM averages, and current guidelines recommend the BP measurements to be performed at least in the morning and in the evening . Up to this date these home-derived daytime BP fluctuations have been related to several factors such as male gender , older age, use of antihypertensive medications, regular alcohol drinking , sleep apnea , insomnia , pre- or postbathing time , pre- or postprandial time , smoking and tobacco exposure , and past history of cardiovascular disease .
In this study we attempted to clarify the determinants of home MEdiff in a standardized fashion in Argentine medicated patients referred to an institution for BP control.

Why Would My Blood Pressure Only Spike In The Evening From 7 To 12 Pm
howard90860
I Discovered I had a BP of 206/110 on Nov 27/2017. I have had borderline hypertension for the last 15 years which didn’t require any medication and my doctor couldn’t advise any lifestyle changes that I wasn’t already doing.
I’m 63, healthy, 6.1″ and 184lbs, at the gym 4 times a week, low sodium ovo/lacto vegetarian & daily Zen meditation practitioner for the last 44 years, drink plenty of water, non smoker, non drinker, good sleep regiment, now retired with a low stress lifestyle. My mom did had BP problems with many mini strokes so they think this is an inherited condition. Numerous blood and urine tests for me come back as all good.
My Doctor has now proscribed 4mg daily Coversyl since my high BP reading.. I have been measuring my own BP about 5 times a day since then. This medicine lowers my BP through most of my day to a good range but the systolic still rises by 30mg back to the hyper tension range from 7 – 12 pm every evening. Taking my medication at different times doesn’t change this. Taking a nap during the day makes no difference to it.
Does anyone have evening BP spikes or any possible explanations for why it consistently rises in the evening?
3 years ago
Hi Howard
It may be because we tend to eat more in the evening, not really sure though. Your BP is very high, yet you seem to have a healthy enough lifestyle. Are you aware that a vit D deficiency can cause high blood pressure? maybe you could ask your doc to test you for a deficiency.

Why Is Blood Pressure Important
That steady stream of blood delivers oxygen and other nutrients that all the different parts of your body need to survive.
“Blood pressure is critical,” says Michael Blaha, MD, MPH, professor of medicine and director of clinical research at Johns Hopkins University’s Ciccarone Center for the Prevention of Cardiovascular Disease, adding that blood pressure needs to be high enough to sustain your everyday functions. “There is a blood pressure below which you can’t live.”
On the other hand, uncontrolled high blood pressure also called hypertension can kill you over time by damaging your blood vessels and organs, according to the ACC.
Reasons Your Blood Pressure Fluctuates
If you are seeing regular fluctuations in your blood pressure readings, youre not alone. Some variation in your blood pressure throughout the day is normal. In fact, there are a number of reasons for this including small changes in daily life, such as stress, exercise or even how well you slept the night before.
According to the American Heart Association , there are more than 116 million adults in the U.S. with high blood pressure. Recently, the U.S. Surgeon General, VADM Jerome Adams, released a for hypertension control to make it a national public health priority. Experts have called for monitoring your blood pressure at home because it is a great way to gain a better understanding of your numbers.
Knowing and regularly measuring your can help you see irregularities that you want to call to your doctors attention. Keeping track of your numbers may help your doctor determine a course of action or treatment. If variances in your blood pressure readings exist, it is important to know that there are some factors you can controlbut some you cant. Lets look at some of the reasons that may cause your blood pressure to fluctuate.
