Extremely high blood pressure that leads to strokes, heart attacks and acute kidney damage, classified as hypertensive emergency, is five times higher in inner-city African-American patients than the national average, according to a recent study co-lead by a Rutgers researcher.
The study, which is the largest one of its kind to compare the development of hypertensive emergency in a United States inner city, appears in the journal Blood Pressure.
One in three adults have high blood pressure known as hypertension, with the highest rates among African-Americans. In addition to being very common, high blood pressure in African-Americans develops earlier in life but has lower control rates compared to other racial-ethnic groups. Higher than average blood pressure results in the development of serious health complications that come with it. The study sought to determine the prevalence and risk factors of high blood pressure escalating to severe cases among African-Americans.
MILWAUKEE – It isn’t easy to be patient when you can’t work and you’re in pain, as Christine Morgan knows all too well.
Her chronic pain comes from fibromyalgia. Morgan, 60, also has spinal stenosis, a narrowing of the spaces within the spine that pinches the nerves, most often in the lower back and neck. To top it off, she is diabetic, has kidney disease, high blood pressure and depression.
Yet Morgan has been turned down for Social Security Disability Insurance – twice. “They sent me a letter that said I wasn’t disabled,” she said.
There are marked gender differences in what drives blood pressure in middle-age in adulthood, suggesting the need for gender-specific treatments for high blood pressure, according to research presented today at the American Heart Association (AHA) Council on Hypertension, AHA Council on Kidney in Cardiovascular Disease, American Society of Hypertension Joint Scientific Sessions 2017, in San Francisco.
“Blood pressure is determined mainly by three factors: heart rate; stroke volume, which is the volume of blood pumped by the heart; and the resistance to blood flow through the vessels, called total peripheral resistance. An increase in any one of the three factors can lead to an increase in blood pressure,” said study author Catriona Syme, Ph.D., postdoctoral fellow at The Hospital for Sick Children (SickKids) in Toronto, Ontario, Canada. “The key takeaway from this study is that, for young and middle-aged women, stroke volume was the main determinant of blood pressure, while, in men, vascular resistance was the main determinant of blood pressure.”
Young adults, particularly men, lag behind middle-aged and older adults in awareness and treatment of high blood pressure, putting this population at an increased risk for heart attack and stroke, according to new research in the American Heart Association’s journal Hypertension.
High blood pressure is a leading risk factor for heart attack and stroke and is also a significant public health burden, costing the United States about $110 billion in direct and indirect costs in 2015, according to American Heart Association estimates. American Heart Association guidelines define blood pressure as normal at less than 120/80 and high blood pressure as 140/90 or above.
Is being born in states with high stroke mortality associated with dementia risk in a group of individuals who eventually all lived outside those states?
A new article published by JAMA Neurology reports the results of a study that examined that question in a group of 7,423 members of the integrated health care delivery system Kaiser Permanente Northern California.
A band of states in the southern United States is known as the Stroke Belt because living there has been associated with increased risk of a number of conditions, including high blood pressure, diabetes, stroke and cognitive impairment.
A large, long-term study suggests that middle aged Americans who have vascular health risk factors, including diabetes, high blood pressure and smoking, have a greater chance of suffering from dementia later in life. The study, published in JAMA Neurology, was funded by the National Institutes of Health (NIH).
“With an aging population, dementia is becoming a greater health concern. This study supports the importance of controlling vascular risk factors like high blood pressure early in life in an effort to prevent dementia as we age,” said Walter J. Koroshetz, M.D., director of NIH’s National Institute of Neurological Disorders and Stroke (NINDS), which partially funded the study and created the Mind Your Risks® public health campaign to make people more aware of the link between cardiovascular and brain health. “What’s good for the heart is good for the brain,” he added.
Americans of South Asian descent are twice as likely as whites to have risks for heart disease, stroke and diabetes, when their weight is in the normal range, according to a study headed by Emory University and UC San Francisco.
Similarly, Americans of Hispanic descent were 80 percent more likely than whites to suffer from so-called cardio-metabolic abnormalities that give rise to heart disease, stroke and diabetes, compared with 50 percent more likely for those who were Chinese and African-American.
These risks include high blood pressure (hypertension), elevated glucose, low HDL, the “good cholesterol,” and high triglycerides, a fat found in blood. In the study, participants who were aged between 45 and 84, were classified as having cardio-metabolic abnormalities if they had two or more of these four risk factors.
An analysis of the records of UK patients who had experienced a stroke has found that over half of those who should get drugs to prevent strokes were not prescribed them.
Across the UK, that amounts to 33% of all stroke and ‘mini-stroke’ (transient ischaemic attack, or TIA) patients having a ‘missed opportunity’ for preventative treatment.
Three types of patients are recommended to have drugs to prevent strokes; patients with high blood pressure, patients who are at high risk of a stroke, and patients with an irregular heartbeat — called atrial fibrillation.
High blood pressure in middle age can lead to impaired cognition and is a potential risk factor for Alzheimer’s disease, according to a statement from the American Heart Association co-authored by Loyola Medicine neurologist José Biller, MD.
Dr. Biller is a member of the multidisciplinary panel of experts that wrote the statement, published in the heart association journalHypertension. Dr. Biller is chair of the department of neurology of Loyola University Chicago Stritch School of Medicine. The panel is chaired by Constantino Iadecola, MD, of Weill Cornell Medicine and co-chaired by Kristine Yaffe, MD, of the University of California San Francisco.
Dementia affects an estimated 30 to 40 million people worldwide, and the number is expected to triple by 2050 due to an aging population and other factors.
