Hypertension sufferers may benefit from nighttime treatment

Saturday, October 29th, 2011

A new development in cardiac health could lead to a drastic improvement in your risk of heart attack and stroke, and all it takes is a little change in your daily routine.

According to MSNBC, Spanish researchers have discovered that instead of taking blood pressure medication in the morning, it may be best to do it before bed, as it allegedly cuts the risk of cardiovascular issues by more than 65 percent.

One reason for the timing is that statistically, most heart attacks occur in the morning. Blood pressure changes throughout the day as well, depending on who you ask. Many medical professionals and researchers’ opinions vary on the latter topic.

“Mother Nature had in mind that when we went to sleep at night our heart rate and blood pressure would decline” to help the body rest, Michael Smolensky, of the University of Texas at Austin’s biomedical engineering department, told the news provider.

While some experts, including study author Ramon Hermida, maintain that nighttime hypertension treatments are the “most effective, cost-free approach to obtain the goal of greater sleep blood pressure reduction,” Hermida and Smolensky both stress that every patient should be individually assessed by their care provider. It is important that each case is looked at separately, rather than generalizing treatments, because some patients may experience too much of a decline in their blood pressure if they take the medication before bed.

“Ours is just the very first trial ever testing the influence on cardiovascular morbidity and mortality of awakening vs. bedtime hypertension treatment,” Hermida told the source. “Further studies will be needed to corroborate our findings.”

Study links sleep quality to high blood pressure

Wednesday, August 31st, 2011

More than 31 percent of Americans suffer from high blood pressure, an asymptomatic condition that many people don’t even realize they have, according to the Centers for Disease Control. Because patients typically do not exhibit any signs of hypertension, it is important to get checked out regularly and, as researchers recently discovered, to get some quality shut-eye.

According to CNN, a study of more than 800 men over the age of 65 revealed that those who got the least amount of deep sleep were 80 percent more at risk for high blood pressure than men who had better quality sleep. For a three-year period, at-home sleep tests were used to measure participants’ non-rapid eye movement sleep (also referred to as slow-wave sleep and deep sleep).

“Our study shows for the first time that poor-quality sleep, reflected by reduced slow-wave sleep, puts individuals at significantly increased risk of developing high blood pressure and that this effect appears to be independent of the influence of breathing pauses during sleep,” Dr. Susan Redline, Professor of Sleep Medicine at Boston’s Brigham and Women’s Hospital and Beth Israel Deaconess Medical Center, told the news provider.

When one is in a state of deep sleep, breathing rate, blood pressure and heart rate all decrease in order to restore the body’s energy. Without this routine slowdown, blood vessels can become damaged and the part of the brain that regulates blood pressure may be impaired as well.

Although hypertension can be asymptomatic, simply paying attention to your sleeping habits can potentially help prevent heart disease and other conditions.

“If you don’t sleep properly, are tired during the day, you snore or your wife or husband says you don’t breathe well [while asleep], get it checked out to see if you have a sleep problem,” Dr. Donald LaVan, National Spokesman for the American Heart Association, told the news source.

UK sets new guidelines to curb hypertension misdiagnoses

There are new guidelines for diagnosing high blood pressure in the U.K., as the National Institute for Health and Clinical Excellence (NICE) has decided that 24-hour monitoring can be more accurate than a doctor’s visit, reports the Guardian.

According to the news source, more than 25 percent of patients in the U.K have may have been misdiagnosed with high blood pressure with the current method of wearing a cuff for two minutes at the hospital. Even if blood pressure is normal regularly, patients can be misdiagnosed thanks to what doctors refer to as “white-coat hypertension,” in which blood pressure is elevated while at the hospital.

To counteract this problem, NICE has altered its guidelines for diagnosis, suggesting that patients wear a monitor for 24 hours.

“Ambulatory blood pressure monitoring (ABPM) involves wearing a cuff and a box on a belt for a day,” said the news provider. “The patient then brings it back the following day for the recording to be downloaded on to a computer and an automatic report is generated.”

Also under the new guidelines, treatment for hypertension is recommended for individuals over the age of 80 as well.

“The number of people with high blood pressure in the U.K. is staggering,” Cathy Ross, senior cardiac nurse at the British Heart Foundation, told the Guardian. “It’s a major risk factor for heart disease and strokes so it’s crucial we do all we can to get people diagnosed and properly treated as soon as possible.”

With the ABPM leading the way for more accurate diagnoses, both patients and hospitals will save money. It is a cost-effective method for medical facilities and can also save people from being misdiagnosed and spending money on improper treatments.

Most common user conditions: Pulmonary hypertension

Wednesday, August 24th, 2011

This week in our most common conditions series, we highlight pulmonary hypertension (PH), which affects more than 215 Healthetreatment members.

This disease, also known as pulmonary arterial hypertension (PAH), is characterized by high blood pressure in the the pulmonary artery (the tube that connects the lungs and the heart). Raised pressure causes the right heart to become enlarged, which is potentially fatal if left untreated. Most of our members who suffer from this illness are female, at 88 percent.

Most symptoms of pulmonary hypertension were given a rating of 4/5 for severity, with the most common being shortness of breath. Nearly 70 percent of Healthetreatment users experienced this disruption in their breathing. More than half reported suffering from heart palpitations, while others also experienced chest pain, fainting, fatigue and malaise.

Some of the most popular treatments for PH are sildenafil (also known by brand names Viagra or Revatio), bosentan (Tracleer) and warfarin (Coumadin). Other treatments that our members have reported include oxygen supplementation, Remodulin, Lasix, Fiolan and tadalafil.

PAH is the most common form of this heart disease, while the idiopathic (IPAH) and familiar (FPAH) forms are not seen as often. The latter two can be difficult to catch in the early stages, as symptoms may resemble asthma and lead to a misdiagnosis, or the patient may not exhibit any symptoms to diagnose until much later. FPAH is the only form of pulmonary hypertension that is known to be caused by genetics. Other forms can be caused by scleroderma, pulmonary embolisms or blood clots in the lungs.

Certain drugs proved ineffective for the treatment of pulmonary hypertension

Thursday, May 26th, 2011

Pulmonary arterial hypertension (PAH) is a heart-related lung condition in which the pulmonary artery (providing the connection between the lungs and heart) experiences high pressure and thus, enlargement of the right ventricle. While treatments like aspirin or simvastatin are often used to relieve the symptoms of heart diseases, research has revealed that these remedies are ineffective for those suffering from PAH.

According to a study performed by the U.S. National Institutes of Health, participants with PAH were either given aspirin, simvastatin, both treatments or a placebo drug to determine whether the medications had any positive effect on the condition. Dr. Steven Kawut, a professor of medicine and epidemiology at the University of Pennsylvania’s School of Medicine, who authored the study, was not expecting the results that came about after six months.

“Surprisingly, we found no evidence that aspirin or simvastatin had beneficial clinical effects in this population,” he said. Ultimately, Kawut determined that patients could take these drugs for their FDA-approved uses, but should not be relied on primarily for the treatment of PAH.

The researcher also emphasized that studies like this are important, as certain “cardiovascular therapies and drugs which appear effective in the laboratory” may not always be effective for human use.

Kuwat and his team presented their findings last week in Denver, Colorado, at the American Thoracic Society conference.
