For Real, We May Be Taking Blood Pressure Readings All Wrong

For people who had high blood pressure readings only when sitting (normal readings while lying down), there was no statistically significant difference in risk of coronary heart disease, heart failure, or stroke compared to people with normal blood pressure. The only statistically significant differences were a 41 percent higher risk of fatal coronary heart disease (compared to the 78 percent seen in those with high readings lying down) and an 11 percent higher risk of all-cause mortality.

(In this study, high blood pressure readings were defined for both positions as those with systolic readings (the top number) of 130 mm Hg or greater or diastolic readings (the bottom number) of 80 mm Hg or greater.)

The people with the highest risks across the board were those who had high blood pressure readings while both sitting and lying down.

"These findings suggest that measuring supine [lying down] BP may be useful for identifying elevated BP and latent CVD risk," the researchers conclude.

For now, the findings should be considered preliminary. Such an analysis and finding should be repeated with a different group of people to confirm the link. And as to the bigger question of whether using medication to lower supine blood pressure (rather than seated blood pressure) is more effective at reducing risk, it's likely that clinical trials will be necessary.

Still, the analysis had some notable strengths that make the findings attention-worthy. The study's size and design are robust. Researchers tapped into data from the Atherosclerosis Risk in Communities (ARIC) study, a study established in 1987 with middle-aged people living in one of four US communities (Forsyth County, North Carolina; Jackson, Mississippi; suburban Minneapolis, Minnesota; and Washington County, Maryland).


The Hidden Dangers Of Untreated High Blood Pressure After 50

High blood pressure, also known as hypertension, is often called the "silent killer" because it can cause serious harm without obvious symptoms.

After the age of 50, the risks of untreated high blood pressure become even greater, as it can lead to life-threatening complications that impact the heart, brain, kidneys, and more.

Understanding these risks is crucial, as managing blood pressure can make a significant difference in long-term health and quality of life.

Research shows that high blood pressure is a leading cause of heart disease and stroke, especially in people over 50. When blood pressure is consistently high, it puts extra strain on the arteries, causing them to become stiff or narrow over time.

This process, known as atherosclerosis, can lead to heart attacks when blood flow to the heart is blocked. Studies indicate that people with untreated hypertension are up to three times more likely to experience a heart attack compared to those with normal blood pressure.

Strokes are another major risk associated with untreated high blood pressure. High blood pressure can weaken blood vessels in the brain, making them more likely to rupture or become blocked. Both scenarios can cause a stroke, which is a medical emergency that often leads to permanent damage or even death.

Research has found that nearly half of all strokes are linked to uncontrolled hypertension, highlighting the importance of managing blood pressure to protect brain health.

Kidney damage is another serious concern, as the kidneys rely on healthy blood vessels to filter waste from the blood. When blood pressure is too high, it can damage these vessels, reducing kidney function over time.

Chronic kidney disease is a common result of untreated hypertension, and in severe cases, it can lead to kidney failure requiring dialysis or a transplant. Studies suggest that high blood pressure is one of the leading causes of kidney disease in older adults.

Untreated high blood pressure also increases the risk of developing vascular dementia, a condition caused by reduced blood flow to the brain.

This type of dementia can lead to memory problems, confusion, and difficulty with daily tasks. Research has shown that people with uncontrolled hypertension are at a significantly higher risk of cognitive decline as they age.

For many people, high blood pressure can also strain the heart itself, leading to a condition called heart failure. This happens when the heart becomes too weak to pump blood effectively, causing symptoms like shortness of breath, fatigue, and swelling in the legs.

Studies reveal that untreated hypertension is a major contributor to heart failure, particularly in older adults.

One of the most concerning aspects of high blood pressure is that it often has no noticeable symptoms until severe damage has already occurred. T

his is why regular check-ups and blood pressure monitoring are so important, especially after the age of 50.

Simple lifestyle changes, such as eating a healthy diet, exercising regularly, reducing salt intake, and managing stress, can significantly lower blood pressure. In some cases, medications may be needed to control it effectively.

Ignoring high blood pressure can have devastating consequences, but the good news is that it's never too late to take action. Managing blood pressure can reduce the risk of heart attacks, strokes, and other complications, helping you live a healthier and longer life.

By being proactive about blood pressure, you can protect your health and enjoy the years ahead with peace of mind.

Understanding The Link Between Renovascular Disease And Hypertension

Hypertension is a common cause of renovascular disease. The disease can affect the way blood flows in your kidneys and worsen your blood pressure, leading to secondary hypertension.

Renovascular disease (RVD) is an umbrella term for conditions that affect the way your blood flows through your kidneys.

RVDs have several possible causes. One of the most common causes is high blood pressure (hypertension). Once hypertension affects your kidneys, it can decrease blood vessel function and subsequently worsen your blood pressure.

If you have RVD, it's important to consider its links with hypertension. Read on to learn more about the causes, symptoms, and treatment options of this serious condition.

While increased blood pressure can contribute to RVD, having renal (kidney) problems can also lead to hypertension. This is also known as renovascular hypertension (RVH). In fact, RVD is a common cause of secondary hypertension.

Hypertension develops when the amount of force from your blood against your blood vessels is too high. This can affect all areas of your body, including your kidneys.

Over time, hypertension weakens and narrows blood vessels, which can decrease blood flow.

When your kidneys are affected, they cannot perform normal functions such as waste and excess fluid removal through your urinary system. Waste and excess fluid can then build up in your kidneys and raise your blood pressure even further.

The cycle of hypertension and renovascular disease and subsequent increased blood pressure can eventually lead to permanent blood vessel damage and kidney failure.

If you have RVH, you may also be at risk of other complications related to elevated blood pressure, such as:

Also, while blood pressure-lowering medications may be used to treat renovascular disease, RAS is often resistant to antihypertensive drugs and may require multiple types to be successful.

Since RVD may not cause symptoms in its early stages and hypertension is asymptomatic, it's important to see a healthcare professional for regular blood tests for early detection, especially if you have any of the risk factors.

Renovascular disease (RVD) and hypertension can go hand in hand. While elevated blood pressure is one possible contributor to renovascular disease development, having RVD can also lead to secondary hypertension or RVH.

Like RVD, RVH is considered a serious condition. Treatment and lifestyle changes are required to help lower your blood pressure and prevent further kidney damage. Left untreated, kidney failure, heart disease, and stroke are all possible complications.

Talk with a doctor if you're concerned about your personal risk of developing RVH or if you're experiencing possible signs of advanced kidney disease. They can help determine the next appropriate steps to reduce further health consequences.

Roseola vs. measles rash: What is the difference? - Medical News Today

Image
Roseola and measles are two different diseases that present with a high fever and a rash. They are both most commonly seen in childhood, although measles can affect people of any age, and roseola in adults is very rare. While both diseases share similarities, there are distinguishing factors, such as how the symptoms present and the disease progression. Read on to find out the difference between roseola and measles rashes. Roseola, also known as roseola infantum, sixth disease, or exanthema subitum, is a viral infection that typically affects children. The human herpesvirus 6 (HHV-6) or human herpesvirus 7 (HHV-7) causes roseola. The disease is spread through tiny respiratory droplets that people either breathe in or pick up from surfaces they touch. This disease usually presents in children between the ages of 6–12 months . Children who have this disease experience a high fever, followed by a pink or red rash. Roseola is a self-limiting viral illness, meaning it will typically go awa...
