Ventilation–Perfusion Scintigraphy Is More Sensitive than Multidetector CTPA in Detecting Chronic Thromboembolic Pulmonary Disease as a Treatable Cause of Pulmonary Hypertension
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).
Why Your Normal Blood Pressure Reading Could Be Lying
Medical experts explain how high blood pressure secretly damages your heart and what you can do about it
High blood pressure silently affects millions worldwide, often showing no symptoms until significant damage has occurred. Medical experts warn that this stealthy condition poses a grave threat to heart health, potentially leading to devastating complications if left unchecked. Understanding its impact could mean the difference between life and death.
Breaking down the pressureBlood pressure represents the force exerted against artery walls as blood circulates through the body. When this pressure consistently rises above normal levels, it begins a dangerous cycle of strain on the cardiovascular system. Doctors explain that this elevated pressure forces the heart to work harder with each beat, gradually wearing down this vital organ.
Hidden heart damageCardiologists reveal that chronic high blood pressure inflicts damage in multiple ways. The increased workload causes the heart muscle to thicken, making it less efficient at pumping blood. Additionally, the constant pressure damages blood vessel walls, creating ideal conditions for dangerous plaque buildup and potential blockages.
Risk factors unveiledMedical research identifies several factors contributing to high blood pressure, including genetics, age, and lifestyle choices. Modern living patterns, characterized by sedentary behavior, processed food consumption, and chronic stress, significantly increase hypertension risk. Understanding these factors helps individuals identify their personal risk level.
Early warning signsWhile high blood pressure often develops without obvious symptoms, doctors highlight subtle signs that shouldn't be ignored. These may include early morning headaches, irregular heartbeat, vision changes, or unexplained fatigue. However, regular blood pressure monitoring remains the most reliable detection method.
Cardiovascular complicationsLeft untreated, high blood pressure can lead to severe cardiovascular complications. Medical experts point to increased risks of heart attacks, strokes, and heart failure. The condition also contributes to kidney damage and cognitive decline, emphasizing the importance of early intervention.
Prevention strategiesHealthcare providers emphasize the significance of preventive measures in managing blood pressure. A heart-healthy diet, regular physical activity, and stress management form the foundation of prevention. Small lifestyle changes can yield significant improvements in blood pressure control.
Dietary impactNutritionists highlight the crucial role of diet in blood pressure management. Reducing sodium intake, increasing potassium-rich foods, and limiting processed foods can significantly impact blood pressure levels. The DASH diet, specifically designed for hypertension management, provides a structured approach to healthy eating.
Exercise benefitsPhysical activity proves essential in maintaining healthy blood pressure levels. Regular exercise strengthens the heart, improves blood vessel flexibility, and helps maintain a healthy weight. Medical experts recommend at least 150 minutes of moderate-intensity activity weekly for optimal benefits.
Stress managementChronic stress contributes significantly to high blood pressure. Healthcare providers emphasize the importance of stress reduction techniques, including meditation, deep breathing exercises, and adequate sleep. Managing stress effectively can help prevent blood pressure spikes and promote overall cardiovascular health.
Medical interventionsWhen lifestyle changes aren't sufficient, various medications can effectively control blood pressure. Healthcare providers carefully select appropriate medications based on individual patient factors, often combining different drug classes for optimal results.
Monitoring importanceRegular blood pressure monitoring plays a crucial role in management. Home monitoring devices provide valuable information about blood pressure patterns and treatment effectiveness. Healthcare providers recommend keeping detailed records to track progress and identify concerning trends.
Long-term outlookWith proper management, individuals with high blood pressure can lead healthy lives and reduce their risk of complications. However, consistent adherence to treatment plans and lifestyle modifications remains essential for long-term success.
Latest researchOngoing research continues to uncover new aspects of high blood pressure's impact on heart health. Scientists investigate innovative treatment approaches and prevention strategies, offering hope for improved management options in the future.
Taking actionHealthcare providers emphasize that knowledge alone isn't sufficient; taking action is crucial. Regular check-ups, medication adherence, and lifestyle modifications form the cornerstone of effective blood pressure management and heart health protection.
Pharmacist Warns Common Cold And Flu Medicine Can Cause Issues With Your Blood

A common medication taken to lessen flu symptoms may raise your blood pressure, a health expert has warned. Pharmica's Superintendent Pharmacist Carolina Goncalves told the Mirror that both the flu and flu medication can impact your blood pressure.
"When you're sick, your body is under stress as it fights off the infection, and that stress can cause a temporary increase in blood pressure. In particular, your immune system releases pro-inflammatory cytokines which promote inflammation and the release of stress hormones such as adrenaline," she explained.
"This is especially something to watch out for if you already have high blood pressure (hypertension), as the added strain could push your blood pressure levels higher than normal. Another important factor to consider is fever. When you have a fever, your body's metabolic rate increases as it works to fight off the infection.
"This heightened activity causes your heart to pump more vigorously to circulate blood faster, ensuring oxygen and immune cells reach affected tissues. This increase in cardiac output can elevate blood pressure by 10-20 points in some individuals, but everyone responds differently. "
At the same time, decongestants could raise your blood pressure. Goncalves warned: "If your blood pressure is within a healthy range and you have no heart-related concerns, short-term use of decongestants as directed is generally safe. However, for individuals with hypertension, heart disease or other cardiovascular risks, decongestants might not be advisable."

The same guidance applies if you're taking other medicines or you have diabetes, an enlarged prostate, increased pressure in the eye, an overactive thyroid gland or liver, kidney, heart or circulation problems.
While you should speak to your GP about any health concerns, you may wish to check your blood pressure at home if you have a digital monitor. Sharing advice, Goncalves said: "You can determine if your blood pressure is raised by checking the reading on a digital monitor.
"This measures blood pressure in millimetres of mercury (mmHg) and provides two numbers: the systolic pressure (the top number, indicating the pressure when your heart pumps blood) and the diastolic pressure (the bottom number, indicating the pressure when your heart rests between beats).
"A normal blood pressure reading is between 90/60mmHg and 120/80mmHg. Raised blood pressure is identified as 135/85mmHg or higher when measured at home, or 140/90mmHg or higher when taken at a GP surgery, pharmacy or clinic.
"The NHS advises seeking medical advice if your blood pressure consistently exceeds these thresholds, as this may indicate hypertension. Additionally, if your systolic pressure reaches 180mmHg or higher, or your diastolic pressure is 120mmHg or higher, you should seek immediate medical attention, as this could signal a hypertensive crisis requiring urgent care."
