MedicalResearch.com Interview with: Xing Gao, MPH, lead author and doctoral candidate in Dr. Mujahid's research group Mahasin Mujahid, MS, PhD, FAHA Lillian E. I. and Dudley J. Aldous Chair in the School of Public Health Associate Professor of Epidemiology Director, Epidemiology & Biostatistics Master of Public Health Program UC Berkeley, School of Public Health MedicalResearch.com:  What is the background for this study?  What are the main findings?
  • ​​Hypertension is a major risk factor for cardiovascular diseases, and persistent racial and ethnic inequities in hypertension remain an urgent public health challenge.
  • Public health researchers need a more nuanced understanding of how structural factors contribute to these inequities, which has a direct application to improving the cardiovascular health of marginalized populations.
  • This study examined associations between racial residential segregation, a product of historical and contemporary racially discriminatory policies, and hypertension in a multi-racial cohort of middle-aged and older adults.

AHA Journals, Author Interviews, Obstructive Sleep Apnea, UCSF / 21.06.2021

MedicalResearch.com Interview with: Yerem Yeghiazarians, MD Professor of Medicine Leone-Perkins Family Endowed Chair in Cardiology San Francisco Board Past-President, American Heart Association Co-Director, Adult Cardiac Catheterization Laboratory Director, Peripheral Interventional Cardiology Program Director, Translational Cardiac Stem Cell Program Cardiovascular Research Institute Eli and Edythe Broad Center of Regeneration Medicine and Stem Cell Research Associate Member in Experimental Therapeutics, UCSF Helen Diller Cancer Center University of California, San Francisco MedicalResearch.com: What is the background for this study? Response: Obstructive sleep apnea is very common, undiagnosed and undertreated. The AHA Scientific Statement was prepared to increase awareness amongst physicians and patients about this condition and to encourage more screening and therapy as appropriate. Obesity is certainly one of the significant risk factors for sleep apnea and we highlight this in the Scientific Statement: “The risk of OSA correlates with body mass index, and obesity remains the one major modifiable risk factor for OSA. In a population-based cohort study of 690 subjects, a 10% weight gain was associated with nearly 32% increase in the apnea-hypopnea index (AHI), and even modest weight control was effective in reducing the new occurrence of sleep-disordered breathing. An even stronger correlation exists between OSA and increased waist circumference and neck size. Neck sizes predisposing to OSA are usually >17 and 16 in for men and women, respectively.” (more…)
AHA Journals, Author Interviews, Blood Pressure - Hypertension, Cognitive Issues, Memory / 21.06.2021

MedicalResearch.com Interview with: Daniel A. Nation, Ph.D., Associate Professor of Psychological Science Institute for Memory Impairments and Neurological Disorders University of California, Irvin MedicalResearch.com: What is the background for this study? Response: Hypertension is a risk factor for cognitive decline and dementia, and treatment of hypertension has been linked to decreased risk for cognitive impairment. Prior studies have attempted to identify which specific type of antihypertensive treatment conveys the most benefit for cognition, but findings have been mixed regarding this question.  We hypothesized that antihypertensive drugs acting on the brain angiotensin system may convey the greatest benefit since they affect the brain angiotensin system that has been implicated in memory function.

MedicalResearch.com Interview with: Dorothy Sears Ph.D. Professor of Nutrition College of Health Solutions Arizona State University MedicalResearch.com: What is the background for this study? Response: Historically, heart disease among women has been understudied despite this being the number one cause of death in women. One in three women will die from heart disease.  Older women are the fasting growing population in the US and after menopause experience a dramatic increase in risk for cardiometabolic diseases such as cardiovascular disease and type 2 diabetes. For these reasons, it is critical to understand the impact of modifiable behaviors on this risk.  Accumulating evidence shows that prolonged sitting is a highly prevalent behavior, associated with cardiometabolic and mortality risk, and greatest in older adults. Thus, overweight or obese postmenopausal women who partake in prolonged sitting time likely have highly compounded cardiometabolic risk. (more…)
AHA Journals, Author Interviews, Blood Pressure - Hypertension, University of Pennsylvania / 09.09.2019

MedicalResearch.com Interview with: Jordana Cohen, MD, MSCE Assistant Professor of Medicine and Epidemiology Renal-Electrolyte and Hypertension Division Center for Clinical Epidemiology and Biostatistics Perelman School of Medicine University of Pennsylvania MedicalResearch.com: What is the background for this study? Response: In the June 18, 2019 issue of Annals of Internal Medicine, we published a systematic review and meta-analysis evaluating the cardiovascular risks of white coat hypertension (WCH; i.e. elevated office blood pressure and normal out-of-office blood pressure). The goal of the meta-analysis was to clarify previous mixed results regarding the risks of untreated WCH and treated WCH. The meta-analysis examined 27 studies – including 64,273 patients – and demonstrated that untreated WCH is associated with an increased risk of cardiovascular events (36%), all-cause mortality (33%), and cardiovascular mortality (109%) compared to normotension. This risk was strongest in studies with a mean age ≥55 years or that included participants with cardiac risk factors, such as diabetes and chronic kidney disease. We found no increased cardiovascular risk associated with treated white coat hypertension. (more…)

MedicalResearch.com Interview with: Dermot Phelan, MD, PhD Director of the Sports Cardiology Center Cleveland Clinic in Cleveland, Ohio MedicalResearch.com: What is the background for this study? Response: It is well recognized that long-term elite endurance athletes are at higher risk of atrial fibrillation.  We wished to evaluate whether this held true for primarily strength-type athletes. We had the opportunity to screen almost 500 former NFL athletes.  It became clear that we were seeing more atrial fibrillation than one would expect during the screenings. (more…)
AHA Journals, Author Interviews, Blood Pressure - Hypertension, Emory, Obstructive Sleep Apnea, Race/Ethnic Diversity, Sleep Disorders / 26.12.2018

MedicalResearch.com Interview with: Dayna A. Johnson PhD Department of Epidemiology Emory University Atlanta, GA MedicalResearch.com: What is the background for this study? What are the main findings? Response: There are several studies that have determined that African Americans have the highest prevalence of hypertension and are the most likely to have uncontrolled hypertension compared to other racial/ethnic groups. We were interested in studying whether sleep apnea contributed to hypertension control among African Americans. We found that participants with sleep apnea were more likely to have resistant hypertension than those without sleep apnea. In particular, individuals with severe sleep apnea had the highest risk of resistant hypertension. Most of the participants with measured sleep apnea were undiagnosed (96%).  (more…)

MedicalResearch.com Interview with: Dr. Sarah Perman MD, M.S.C.E. Assistant professor of Emergency Medicine University of Colorado School of Medicine Denver  MedicalResearch.com: What is the background for this study? Response: Women who suffer an out-of-hospital cardiac arrest have been observed to receive less bystander cardiopulmonary resuscitation (B-CPR) than men, and the potential reasons were largely unknown. We asked 54 people online to explain – with no word limit – why women might be less likely to get CPR when they collapse in public. (more…)

MedicalResearch.com Interview with: Dr. Srikanth Yandrapalli New York Medical College NYMC · Cardiology MedicalResearch.com: What is the background for this study? What are the main findings? Response: Selection of coronary artery bypass grafting over percutaneous coronary intervention during an acute myocardial infarction is influenced by the extent of coronary artery disease and patient comorbidities. Prior studies have shown sex and racial differences in coronary artery diseaseburden. We sought to identify if there are any sex and racial differences in the utilization of  coronary artery bypass grafting over percutaneous coronary intervention during a revascularized first  acute myocardial infarction in the US. We found that males had a higher coronary artery bypass grafting rate than women, and compared to Whites, Blacks had lower coronary artery bypass grafting rate and Asians had higher coronary artery bypass grafting at the time of a first myocardial infarction.
