The Food and Drug Administration publishes on its website information on blood pressure medicines recalled for carcinogenic substances. Here's what to watch out for.

Approximately 103 million Americans have high blood pressure and need to change their lifestyle or take medication to maintain cardiovascular and heart disease.

This number, almost a third of the country, is based on clinical guidelines adopted in 2017 by the American College of Cardiology, the American Heart Association and other groups

About 46% of adults have hypertension according to guidelines, which are more aggressive than those that were previously. They set the threshold for high blood pressure at stage 130/80, compared to the previous 140/90 benchmark.

However, primary care physicians' groups are critical of those standards that they think can provide for over-diagnosis and over-treatment – potential problems when patients do not need them.

American College of Physicians and the American Academy of Family Physicians recommend medications for adults aged 60 or over with blood pressure above 150. People with a history of stroke or heart problems should take medication to keep their blood pressure below 140. 19659005] Different guidelines could confuse patients for the most commonly diagnosed condition during ambulatory medical visits

High blood pressure may contribute to heart failure, heart attack, stroke and chronic kidney but a disease. This causes or contributes to 360,000 deaths in 2013, according to the US Department of Health and Human Resources.

Paul Muntner, a Dean of the University of Alabama, is part of a research team that estimates the number of Americans with high blood pressure based on guidelines from the American College of Cardiology and the American Heart Association.

"Many Americans have blood pressure levels that are unhealthy and are associated with an increased risk of cardiovascular disease," he said. Muntner said it was too early to say whether the 2017 guidelines made a significant difference for patients in limiting stroke or heart attack, or whether patients were more likely to receive blood pressure medications or non-drug therapies.

He estimates that 82 million Americans should have blood pressure lowering drugs, an increase of about 4 million from previous guidelines.

Here are the most commonly prescribed blood pressure lowering drugs, including diuretics, calcium channel blockers, angiotensin converting enzyme (ACE) inhibitors, or blockers of angiotensin II receptors such as valsartan and losartan many of valsartan, losartan and irbesartan either alone or in combination with other drugs have found traces of carcinogens .

Several versions of these drugs were not affected by the seizure. Patients can consult their doctor, pharmacist or the seizure list of the Food and Drug Administration to check if their medicines are part of the seizure.

Most Americans with mild hypertension should be able to lower their blood pressure by lowering their weight, training and eating less salt and more fruits, vegetables and whole grains.

– Physicians who have studied and developed the less aggressive treatment target for older people with blood pressure over 150 say they have tried to balance the benefits of treating high blood pressure with potential harm. – says Devan Kansagaras, associate professor of medicine at the Oregon University of Health and Sciences, and vice chair of the ACP / AFAC Clinical Guidelines Committee. Kansagara said primary care physicians' guidance is aimed at preventing heart attack, stroke, even death, while minimizing the side effects of treatment. "If you ask any patient who has been treated aggressively for blood pressure – we see this in practice all the time – there are many complaints of dizziness, malaise, and a sense of discomfort," Kansagara said.

Kansagara said that more aggressive guidelines can increase the burden of replenishing multiple prescriptions and managing multiple drugs for minimal benefit

He said that doctors and patients should ultimately discuss the benefits and risks of starting treatment based on their overall health.

"Primary care physicians and their patients are healthy and able to cope with this sometimes confusing discussion about controversial issues."
