Keywords

💡Blood Pressure

Blood pressure is the force exerted by circulating blood on the walls of blood vessels. It is a vital sign that indicates the efficiency of a person's circulatory system. In the video, it is crucial as it discusses the importance of monitoring blood pressure, especially at night, to prevent cardiovascular events. The story of Mike, who had a heart attack despite having normal blood pressure readings during the day, underscores the significance of this keyword.

💡Nocturnal Hypertension

Nocturnal hypertension refers to the condition where blood pressure remains high or increases during sleep. The video emphasizes that this condition can silently strain the heart and blood vessels, leading to serious health risks. Mike's case exemplifies nocturnal hypertension, where his blood pressure was dangerously high at night, contributing to his heart attack.

💡Cardiovascular Disease

Cardiovascular disease encompasses a range of conditions affecting the heart and blood vessels, including heart attacks, strokes, and heart failure. The video highlights that untreated or undertreated high blood pressure is a significant risk factor for cardiovascular disease, which can lead to life-threatening events like Mike's heart attack.

💡Ambulatory Blood Pressure Monitor

An ambulatory blood pressure monitor is a device that measures blood pressure at regular intervals throughout the day and night while a person goes about their normal activities. The video suggests using such a device to get a comprehensive understanding of blood pressure patterns, including nocturnal hypertension, which is critical for managing heart health.

💡Left Ventricular Hypertrophy

Left ventricular hypertrophy is a condition where the heart's left ventricle wall thickens, making it harder for the heart to pump blood effectively. In the video, Mike's ultrasound revealed this condition, which was a result of his nocturnal hypertension, highlighting the importance of monitoring and managing blood pressure to prevent such complications.

💡Atherosclerotic Plaques

Atherosclerotic plaques are fatty deposits that can build up in the arteries, narrowing them and restricting blood flow. The video mentions that Mike had significant atherosclerotic plaques in his coronary arteries, which increased his risk of a heart attack, illustrating the connection between blood pressure control and arterial health.

💡Circadian Rhythm

Circadian rhythm refers to the body's internal clock that regulates the sleep-wake cycle and repeats roughly every 24 hours. The video explains that blood pressure also follows a circadian rhythm, typically dipping during sleep to allow the body to rest. However, in some individuals, this rhythm is disrupted, leading to high nighttime blood pressure.

💡Systolic Blood Pressure

Systolic blood pressure is the pressure in the arteries when the heart beats and is the first, higher number in a blood pressure reading. The video cites a study that found nighttime systolic blood pressure to be a more informative measure for predicting mortality and cardiovascular death than daytime readings.

💡Cardiovascular Death

Cardiovascular death refers to fatalities resulting from diseases of the heart and blood vessels. The video discusses the importance of monitoring blood pressure, particularly at night, to reduce the risk of cardiovascular death, as high nighttime blood pressure is associated with a higher risk of such events.

when is the best time to check your

blood pressure in the morning or at

night does it even matter recent studies

suggest that yes not only does it matter

when you check your blood pressure but

it also matters when you take your blood

pressure medications hey everyone Dr

Jeff paying here I'd like to share a

story that might make you rethink

everything you know about your health

meet Mike Mike was in his early 40s

living what most of us would consider an

ideal healthy life he exercised

regularly maintained a balanced diet and

made sure to visit his doctor every year

for his routine checkups his blood tests

always came back normal and his blood

pressure readings at the doctor's office

were consistently within the healthy

range Mike was the picture of Health no

symptoms no warnings just smooth sailing

or so it seemed one day out of nowhere

Mike had a heart attack no one saw it

coming not his family not his friends

and certainly not Mike himself he didn't

fit the profile of someone at risk for a

heart attack there were no signs no red

flags it was a complete shock Mike was

lucky he survived but as he recovered

the questions began to pile up how could

this happen what went wrong Mike had an

extensive workup an ultrasound of his

heart showed left ventricular

hypertrophy this is a condition where

the walls of the left ventricle in the

heart get get thicker making it harder

for the heart to pump blood effectively

he also had significant atherosclerotic

plaques in his coronary arteries this

means that fatty deposits were naring

the arteries that Supply blood to the

heart restricting blood flow and

increasing the risk of a heart attack

but why did this happen as his doctors

examined the data they discovered

something that left Mike stunned at

night when Mike was supposed to be

resting his blood pressure was dangerous

ly high this nocturnal hypertension

slowly and quietly put immense strain on

his heart without him even knowing it

the most frightening part Mike had

absolutely no symptoms during the day

his blood pressure was normal giving him

a false sense of security but at night

his heart was fighting a silent battle a

battle he never even knew was happening

so when is the best time to check your

blood pressure in the morning or at

night does it even matter as Mike

discovered it absolutely does

understanding and controlling your blood

pressure especially at night can be the

difference between life and death you

can feel perfectly fine but your heart

could be silently struggling putting you

at much higher risk for cardiovascular

disease untreated or undertreated high

blood pressure is one of the most common

and significant risk factors for heart

disease and death what's even more

alarming is that many people like Mike

have high blood pressure at night and

don't even know it because they feel

fine during the day our blood pressure

will naturally fluctuate throughout the

day as part of a normal physiological

process these fluctuations are

influenced by various factors including

physical activity stress diet and the

body circadium Rhythm during the day it

rises to help us stay active and at

night it should ideally drop to give our

heart and blood vessels a chance to rest

but for some people

this doesn't happen and recent studies

confirm this hidden danger one study

analyzed data from nearly 60,000

patients over the course of almost 10

years they found that nighttime systolic

blood pressure was the most informative

measure for predicting all cause

mortality and cardiovascular death they

report that nighttime systolic blood

pressure was about six times more

informative for mortality risk than

blood pressure measured during the day

at a doctor's clinic nighttime systolic

blood pressure was also twice as

informative as daytime blood pressures

taken at home so what does this mean

studies show nighttime blood pressure is

one of the most important indicators of

heart health if your blood pressure

stays high or increases at night it

could mean a higher risk of heart

disease stroke or even early death the

scariest part is that you might not even

know it's happening just like Mike so

for regular blood pressure monitoring I

recommend checking blood pressure at

consistent times each day ideally in the

morning as well as in the evening prior

to bed but to really understand your

blood pressure patterns particularly

nighttime blood pressure the best way to

do this is to get an ambulatory or

automatic blood pressure monitor these

are available for purchase online and I

have linked a sample device in the video

description this is not an endorsement

of the device but just a starting point

where you can begin your research these

small devices can be worn for 24 hours

and will automatically take your blood

pressure throughout the day and at night

the readings will give you and your

doctor a detailed picture of your blood

pressure patterns including while you

sleep all of this results in a much more

accurate understanding of your blood

pressure and heart health potentially

catching a hidden risk before it becomes

a life-threatening problem and what

about when to take your blood pressure

medications studies on optimal timing

for taking blood pressure medications

have also highlighted the importance of

managing nighttime blood pressure one

study followed 19,000 people with high

blood pressure and divided them into two

groups one group who took all of their

blood pressure medications at bedtime

and another group that took all of their

blood pressure medications after waking

up in the morning after 6 years of

followup researchers found that those

who took their medication patients at

bedtime had significantly better control

of their blood pressure and a much lower

risk of developing major cardiovascular

events such as heart attacks Strokes

heart failure and even cardiovascular

death we're not 100% sure how to explain

these findings but there are a few

hypotheses first just like how we have a

normal wake and sleep cycle our blood

pressure also has its own circadium

Rhythm our blood pressures dip about 10

to 20% during sleep and is crucial for

reducing cardiovascular strain and

allowing the body to rest and repair in

some individuals this dip is either

absent or Worse blood pressure increases

at night persistent high blood pressure

at night increases the workload on the

heart and blood vessels and this leads

to structural changes such as left

ventricular hypertrophy and arterial

stiffness chronic high nighttime blood

pressure can also damage the endothelial

lining of blood vessels promoting

inflammation oxidative stress and

contributing to

atherosclerosis all of these changes

increase the risk of cardiovascular

events such as heart attacks Strokes

heart failure and arhythmia or irregular

heart beats so by taking your blood

pressure medications at night you

ensuring the medications are doing their

best to keep your blood pressure

controlled when it matters most it helps

lower your blood pressure and protects

your heart when your body should be

resting now I want to quickly point out

that all of this information is just

based on what studies say the true best

time to measure blood pressure or take

your blood pressure medication is

whenever you best remember and that's

because the most important factor in

determining what kind of results you

will get with your medications is how

often you miss a dose or how often you

forget to take your medications before

making any changes to your routine be

sure to consult with your health care

provider to find the best strategy for

you lastly we know medications are only

one of many treatments to lower blood

pressure daily exercise is also

critically important and just like with

timing of blood pressure the type of

exercise you choose will have a varying

impact on lowering your blood pressure

studies suggest one particular type of

exercise is far more effective than

others in controlling blood pressure

check out this next video where I will

reveal what it is and how easy it is to

incorporate it into your daily life
