The study found associations between SNPs and differential responses to different antihypertensive drugs, highlighting potential for tailored treatment regimens.
Studies have shown that hypertension awareness, treatment, and control are lower among Hispanics compared to non-Hispanics. However, a recent study found that Hispanic men and women responded as well or better than non-Hispanics when treated aggressively with medication. At four years, blood pressure was controlled in 72% of Hispanic w...
A new study published in Annals of Internal Medicine found that preventing or reducing left ventricular hypertrophy (LVH) decreases the risk of heart failure in high-blood-pressure patients. The study, led by Dr. Peter Okin, demonstrated a significant reduction in heart failure risk among patients with reduced LVH levels.

Despite this, researchers believe exercise still has potential benefits for reducing blood pressure. The study's findings highlight the complexity of understanding hypertension in African Americans.
The Lancet Editorial warns that hypertension's increasing burden will largely stem from poor lifestyles, with a staggering 90% risk of developing the condition in developed countries. Effective treatments exist, yet many patients misbelieve they can 'cure' hypertension and stop medication when their blood pressure falls.
Researchers identified EP1 as a key factor in blood pressure regulation and found that inhibiting it can reduce hypertension. Targeting this receptor subtype may be a viable approach to treating high blood pressure.
Researchers found that impaired energy production in heart muscle may underlie heart failure in some hypertensive patients. A protein called estrogen-related receptor alpha (ERR alpha) helps the heart keep up with energy-draining conditions like high blood pressure.
Researchers found genomic determinants underlying alcohol and tobacco use on chromosomes 1, 3, and 4. A common locus for both was discovered on chromosome 1, with a linked area for smoking also present. The study suggests sex-specific genetic factors may contribute to the observed sex differences in alcohol and tobacco use rates.
Researchers identified distinct genetic factors for blood pressure regulation in males and females, shedding light on gender-based disparities in cardiovascular health. The study's findings suggest that genetic diagnostic and therapeutic indices for hypertension must consider gender differences.
Researchers have found that grape seed polyphenols reduce salt-sensitive hypertension in young rats, while soy polyphenols protect against hypertension in estrogen-depleted/ovariectomized rats. Kudzu root extract also blunts blood pressure rise and improves glucose tolerance in animal models of insulin resistance.
Researchers found that less than a third of treatment guidelines are based on high-quality evidence, highlighting the need for transparent grading systems. The study concludes that clinicians should be aware of this limitation and apply guideline recommendations appropriately to individual patients.
The combination of aliskiren and valsartan significantly lowers blood pressure in patients with hypertension, with a mean drop of 12.2mm Hg compared to 9.0mm Hg for monotherapy. However, the treatment is limited by potential life-threatening side effects, including hyperkalemia.
A Norwegian regulation requiring doctors to prescribe thiazides as first-line treatment for hypertension has led to substantial savings in drug costs. The study found that the proportion of patients prescribed thiazides increased from one in ten to one in four, and blood pressure goals were met by a slightly higher percentage.
Researchers found that a nutritionally balanced diet high in omega-3 fatty acid reduced prostate tumor growth and increased survival in genetically predisposed mice. Omega-6 fatty acids had the opposite effects. The study suggests a beneficial effect of omega-3 polyunsaturated fatty acids on delaying human prostate cancer.
The new guidelines provide up-to-date information on best practices and practical recommendations for diagnosing, assessing, and treating arterial hypertension. The update is based on a thorough review of scientific data from large clinical trials and observational studies.

People with moderate to severe RLS are at increased risk for developing hypertension, with the likelihood of hypertension increasing by 50 percent in those who experienced over 30 PLMs per hour of sleep.
Researchers found a strong association between high arterial pulse pressure and high-tension open-angle glaucoma. Individuals with high pulse pressure were more likely to develop the condition, possibly due to increased carotid arterial stiffness.
Substituting soy nuts for protein sources improves blood pressure and cholesterol levels in postmenopausal women. The study found significant reductions in systolic and diastolic blood pressure, as well as decreased 'bad' cholesterol levels, in women with high blood pressure.
A new international study involving over 10,700 people with high blood pressure found that single-tablet combinations of drugs can bring blood pressure under control for up to 80% of US patients. The six-month treatment period saw a near-doubling of the proportion of patients achieving controlled blood pressure.
A meta-analysis of over 32,000 women and their babies found that taking aspirin or other antiplatelet drugs during pregnancy reduces the risk of pre-eclampsia by 10%. The treatment also has no significant effect on fetal or baby health outcomes.
A new study shows Pycnogenol supplementation can prevent damage to the heart caused by high blood pressure and hypertension. The natural pine bark extract enhanced collagen connective tissues in cardiac tissue, resulting in stronger cardiac chambers.
A study published in Neurology found that people with migraines are 1.3-1.5 times more likely to develop retinopathy than those without headaches. The association was strongest among those with migraine headaches and other headaches with aura, even after controlling for diabetes, glucose levels, and blood pressure.
Researchers found that a single-tablet combination of atorvastatin and amlodipine is less costly and at least as effective in preventing cardiovascular events. The study suggests this approach may be beneficial for patients with high blood pressure, potentially improving treatment outcomes and reducing medical costs.
Research suggests that chunky adolescents are headed in the wrong direction regarding cardiovascular health, with increased blood pressure and sodium intake found across all weight categories.
The review of six large-scale clinical trials found that aliskiren was not more effective than existing antihypertensive drugs in controlling blood pressure. The drug's inability to effectively lower blood pressure was attributed to its stimulation of kidney renin secretion, which can counteract its antihypertensive capabilities.
A study found that new immigrant women had lower risks of maternal placental syndrome and related complications during pregnancy compared to those who had lived in the country for longer. The risk increased with length of residence in Ontario.
Researchers found a link between taking centrally active ACE inhibitors and lower rates of mental decline, with a 50% lower decline in test results compared to other high blood pressure pills. The study suggests that these drugs may slow cognitive decline by reducing inflammation in the brain.
The study found that females have higher levels of nitric oxide synthase, which may contribute to their lower risk of kidney disease. In contrast, males have more AT1 receptors that enable angiotensin 2 to cause damage, leading to a greater risk of hypertension and kidney injury.
Eight South African plant extracts have been found to inhibit angiotensin-converting enzyme (ACE) activity, a potential treatment for high blood pressure. The study identified Tulbaghia violacea, commonly known as wild garlic, as the most promising plant with over 50% ACE inhibition in both extract forms.
