MedicalResearch.com Interview with: [caption id="attachment_55030" align="alignleft" width="115"]Dr.  Clare Oliver-Williams PhD University of Cambridge Dr. Oliver-Williams[/caption] Dr.  Clare Oliver-Williams PhD University of Cambridge MedicalResearch.com: What is the background for this study? Response: Women with PCOS are known to be at greater risk of CVD, however the some symptoms (menstrual irregularity) of PCOS are specific to reproductive age women. This raises the question of whether CVD risk varies across by age, which was the focus of my research with colleagues at the University of Copenhagen. MedicalResearch.com: What should readers take away from your report? Response: Women with PCOS were at 19% higher CVD risk than women without CVD, however once the association was stratified by age, there was no  evidence for a higher CVD risk for women older than 50.

MedicalResearch.com Interview with: Amy Ferry Cardiology Research Nurse Centre for Cardiovascular Science The University of Edinburgh MedicalResearch.com: What is the background for this study? Response: The fourth universal definition of myocardial infarction now recommends the use of sex-specific diagnostic criteria. This approach has revealed a population of patients with myocardial infarction (predominantly women) who were previously unrecognised. The impact of these diagnostic criteria on the presentation and clinical features of men and women with suspected acute coronary syndrome is unknown.

Response:  Coronary heart disease (CHD) is a leading cause of death and disability worldwide. Primary care has been shown to play an important role in the secondary prevention of cardiovascular disease. Yet, studies in Australia and elsewhere from as far back as two decades ago identified gaps in the management of CHD patients in primary care. We analysed records of 130,926 patients with a history of CHD from 438 general practices across Australia to determine whether sex disparities exist in the management of CHD according to current clinical guidelines.

MedicalResearch.com Interview with: [caption id="attachment_36295" align="alignleft" width="160"]Samar R. El Khoudary, PhD, MPH, BPharm, FAHA Associate Professor, Epidemiology PITT Public Health Epidemiology Data Center University of Pittsburgh Pittsburgh, PA 15260  Dr. El Khoudary[/caption] Samar R. El Khoudary, Ph.D., M.P.H. BPharm, FAHA Associate Professor Department of Epidemiology University of Pittsburgh Graduate School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: The background for this study is based on the current measurements used to determine cardiovascular disease risk in postmenopausal women. Higher levels of HDL “good cholesterol” as measured by the widely available clinical test, HDL-Cholesterol, may not always be indicative of a lower risk of cardiovascular disease in postmenopausal women. HDL is a family of particles found in the blood that vary in sizes, cholesterol contents and function. HDL particles can become dysfunctional under certain conditions such as chronic inflammation. HDL has traditionally been measured as the total cholesterol carried by the HDL particles, known as HDL cholesterol. HDL cholesterol, however, does not necessarily reflect the overall concentration, the uneven distribution, or the content and function of HDL particles. We looked at 1,138 women aged 45 through 84 enrolled across the U.S. in the Multi-Ethnic Study of Atherosclerosis (MESA), a medical research study sponsored by the National Heart, Lung and Blood Institute of the National Institutes of Health (NIH). MESA began in 1999 and is still following participants today. We assessed two specific measurements of HDL: the number and size of the HDL particles and total cholesterol carried by HDL particles. Our study also looked at how age when women transitioned into post menopause, and the amount of time since transitioning, may impact the expected cardio-protective associations of HDL measures. Our study points out that the traditional measure of the good cholesterol, HDL cholesterol, fails to portray an accurate depiction of heart disease risk for postmenopausal women. We reported a harmful association between higher HDL cholesterol and atherosclerosis risk that was most evident in women with older age at menopause and who were greater than, or equal to, 10 years into post menopause. In contrast to HDL cholesterol, a higher concentration of total HDL particles was associated with lower risk of atherosclerosis. Additionally, having a high number of small HDL particles was found beneficial for postmenopausal women. These findings persist irrespective of age and how long it has been since women became postmenopausal. On the other hand, large HDL particles are linked to an increased risk of cardiovascular disease close to menopause. Women are subject to a variety of physiological changes in their sex hormones, lipids, body fat deposition and vascular health as they transition through menopause. We are hypothesizing that the decrease of estrogen, a cardio-protective sex hormone, along with other metabolic changes, can trigger chronic inflammation over time, which may alter the quality of HDL particles. Future studies should test this hypothesis. The study findings indicate that measuring size and number of HDL particles can better reflect the well-known cardio-protective features of the good cholesterol in postmenopausal women.

Response: Cardiovascular disease (CVD) is the number 1 killer of women in the U.S.A., yet few younger women personalize awareness. CVD campaigns focus little attention on physicians and their role assessing risk. MedicalResearch.com: What are the main findings? Response: Overall, 45% of women were unaware that CVD is the #1 killer of women, only 11% knew a woman who has died from it.  Overall, 45% of women reported it is common to cancel or postpone a physician appointment until losing weight. Cardiovascular disease was a top concern for only 39% of PCPs, after weight and breast health. A minority of physicians (22% of PCPs and 42% of cardiologists) felt well prepared to assess women’s CVD risk, and infrequently use guidelines.

Assistant professor Department of Epidemiology University of Pittsburgh Graduate School of Public Health Dr. El Khoudary,[/caption] Samar R. El Khoudary, Ph.D., M.P.H. Assistant professor Department of Epidemiology University of Pittsburgh Graduate School of Public Health MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our study revealed a previously unknown, menopause-specific indicator of heart disease risk. For the first time, we’ve pinpointed the type of heart fat, linked it to a risk factor for heart disease and shown that menopausal status and estrogen levels are critical modifying factors of its associated risk in women. My team evaluated clinical data, including blood samples and heart CT scans, on 478 women from Pittsburgh and Chicago enrolled in the Study of Women’s Health Across the Nation (SWAN). The women were in varying stages of menopause, averaged 51 years old and were not on hormone replacement therapy. In a previous study, we showed that a greater volume of paracardial fat, but not epicardial fat, after menopause is associated with a decline in the sex hormone estradiol—the most potent estrogen—in women. The higher volume of epicardial fat was tied to other risk factors, such as obesity. In the new study, we built on those findings to discover that not only is a greater paracardial fat volume specific to menopause, but—in postmenopausal women and women with lower levels of estradiol—it’s also associated with a greater risk of coronary artery calcification, an early sign of heart disease that is measured with a heart CT scan.

MedicalResearch.com Interview with: Dr. Stefano Savonitto  Director, Division of Cardiology Manzoni Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Response: Over the last 15 years, there has been a shift from fibrinolytic therapy for STEMI to primary angioplasty, which required a re-organization of the whole STEMI treatment network. Besides the higher reperfusion efficiency of primary angioplasty, as compared to lytic therapy, it has been a global upgrade of the STEMI care system that has reduced the rate of no reperfusion. Elderly patients and women (who are, on average, also older than men) had theoretically the most to gain from this shift, but little data were available to assess this benefit. In the present paper, we have shown that “lack of reperfusion” was reduced dramatically across all age groups and in both sexes, with a progressive and uniform increase in primary angioplasty, and a significant reduction in mortality. Almost as expected, elderly women were the category with the most relevant mortality benefit. Nevertheless, after adjustment for age and other confounders, women continue to experience a higher mortality as compared to men. In the discussion of the paper, we propose some hypotheses for this persistently higher mortality in women.

MedicalResearch.com Interview with: Dr James Spratt Bsc, MD, FRCP, FESC, FACC Spire Edinburgh Hospitals and Spire Murrayfield Edinburgh Spire Shawfair Park Hospital MedicalResearch.com: What is the background for this study? Response: Gender differences exist between male and female patients following routine PCI but data regarding these differences in Chronic Total Occlusions (CTO) Percutaneous Coronary Intervention (PCI) is limited. We maintain a dedicated national (United Kingdom) prospective CTO database contributed to by dedicated CTO PCI operators (lifetime CTO PCI >300). We retrospectively analysed this database from 2011-2015 to compare outcomes and characteristics of male versus female patients undergoing CTO PCI. We attempted to limit the bias of this observational study by propensity matched analysis.

Response: Prior studies have shown that among patients with obstructive coronary artery disease (CAD), women have higher short- and long-term mortality rates as compared to men. Furthermore, a few studies have highlighted the existence of ethnic differences in the incidence of acute myocardial infarction (AMI) and outcomes following an AMI event. However, the joint contribution of sex and ethnicity on outcomes of patients with obstructive  coronary artery disease remains unknown. Our primary objective was to extend these findings by examining the joint impact of sex and ethnicity on long-term adverse outcomes of all patients with angiographic evidence of obstructive CAD presenting with myocardial ischemia. Our study included a population-based cohort of patients ≥ 20 years of age who underwent coronary angiography for acute coronary syndromes (ACS) or stable angina in British Columbia, Canada with angiographic evidence of ≥ 50% stenosis in any epicardial artery.

MedicalResearch.com Interview with: [caption id="attachment_21884" align="alignleft" width="133"]Dr. Kim Lavoie Dr.Kim Lavoie[/caption] Dr. Kim Lavoie, Ph.D. CIHR New Investigator, FRQS Chercheur-Boursier Co-Director, Montreal Behavioural Medicine Centre Professor, Dept. of Psychology University of Quebec at Montreal Director, Chronic Disease Research Division, Hôpital du Sacré-Coeur de Montreal Adjunct Professor, Faculty of Medicine, University of Montreal Associate Researcher, Montreal Heart Institute Chair, Health Psychology and Behavioral Medicine Section Canadian Psychological Association Medical Research: What is the background for this study? Dr. Lavoie: We were interested in looking at whether rates of ischemia in men and women were different as a function of whether or not you had pre-existing heart disease (we would expect those with existing heart disease to have more ischemia because it’s a major marker of disease) or a comorbid anxiety or mood disorder (we expected anx/mood disorders would be associated with higher rates of ischemia because they reflect clinical levels of chronic stress, which has been linked to higher rates of ischemia in previous studies). Medical Research: What are the main findings? Dr. Lavoie: Overall, we found that men have higher rates of ischemia than women, and that anxiety or mood disorders overall aren't associated with higher or lower risk of ischemia (in those with or without previously diagnosed heart disease). HOWEVER, what we did find that was interesting and perhaps new, was that if you looked within women, those without previously diagnosed heart disease AND anxiety disorders (which including things like panic disorder and generalized anxiety - panickers and worriers) had higher rates of ischemia compared to those without anxiety disorders. This suggests higher rates of ischemia among women without heart disease, which seems counter-intuitive because you would expect those WITH disease to have more ischemia. The fact that anxiety disorders were present in those without previously diagnosed heart disease - and they were the ones with more ischemia, suggests that these women likely HAD heart disease that just hadn't been diagnosed up yet, and that the reason might have been because of their anxiety disorder, which can mask many symptoms of heart disease because many of them overlap (e.g., fatigue, decreased energy, heart palpitations, sweating, chest discomfort, hyperventilation, and fear/worry). This could lead physicians to misinterpret symptoms of real heart disease as those of anxiety - but this only appears to be the case in women according to our study, suggesting a possible sex/gender bias here.

Vladutiu, PhD, MPH Research Assistant Professor, Department of Obstetrics & Gynecology Adjunct Assistant Professor, Department of Epidemiology Chapel Hill, NC Dr. Catherine Vladutiu[/caption] Catherine J. Vladutiu, PhD, MPH Research Assistant Professor, Department of Obstetrics & Gynecology Adjunct Assistant Professor, Department of Epidemiology Chapel Hill, NC Medical Research: What is the background for this study? Dr. Vladutiu: During pregnancy, women experience physiological changes and are at risk of pregnancy-related complications, some of which are associated with a higher risk of cardiovascular health outcomes in later life.  Physiologic adaptations occurring across successive pregnancies may be associated with an even higher risk of adverse cardiovascular outcomes. Previous studies have found an association between higher parity (i.e., number of live births) and the metabolic syndrome (MetS). However, no studies have examined this association in a Hispanic/Latina population. Hispanic women have a higher prevalence of the MetS than non-Hispanic women.  Latinos are also the fastest growing minority population in the U.S. and Hispanic/Latina women report higher fertility and birth rates than their non-Hispanic counterparts.

dr-shannon-dunlayMedicalResearch.com Interview with: Shannon M. Dunlay, M.D. M.S. Advanced Heart Failure and Cardiac Transplantation Assistant Professor of Medicine and Health Care Policy and Research Mayo Clinic Rochester MedicalResearch: What is the background for this study? Dr. Dunlay: Loss of mobility and independence can complicate the care of patients with chronic conditions such as heart failure, and can degrade their quality of life.  However, we have a very poor understanding of the burden of disability in patients with heart failure and how it impacts outcomes.  What are the main findings?  In this study, patients with heart failure were asked whether they had difficulty performing activities of daily living (ADLs)—these include normal activities that most people do in daily life such as eating, bathing, dressing, and walking.  Most patients with heart failure reported having difficulty with at least one ADL at the beginning of the study, and over 1/3 had moderate or severe difficulty with activities of daily living.  Patients who were older, female and had other chronic conditions such as diabetes, dementia and obesity had more difficulty with activities of daily living.  Patients that reported more difficulty with ADLs (worse mobility) were more likely to die and be hospitalized over time.  Some patients had a decline in function over time, and this was also predictive of worse outcomes.

Dawn Pedrotty, MD, PhD Cardiovascular Medicine Fellowship University of PennsylvaniaMedicalResearch.com Interview with: Dawn Pedrotty, MD, PhD Cardiovascular Medicine Fellowship University of Pennsylvania MedicalResearch: What is the background for this review? What are the main findings? Dr. Pedrotty: Heart failure (HF) is the most common cause for hospitalization among patients 65 years and older, affecting approximately 6 million Americans; at 40 years of age, American males and females have a one in five lifetime risk of developing heart failure. There are two distinct heart failure phenotypes: a syndrome with normal or near-normal left ventricular ejection fraction (LVEF) referred to as HF with preserved ejection fraction (HFpEF), and the phenotype associated with poor cardiac contractility or heart failure with reduced ejection fraction (HFrEF). Risk factors associated with HFpEF include female gender, especially women with diabetes, higher body mass index, smoking, hypertension, concentric left ventricular hypertrophy (LVH), and atrial fibrillation (AF). There has been a growing interest in the development of criteria for specific subsets of HFpEF, a syndromal disease where multiple cardiac and vascular abnormalities exist. One approach is to implement phenomapping, identifying phenotypically distinct HFpEF categories and developing a classification system to group together pathophysiologically similar individuals who may respond in a more homogeneous, predictable way to intervention. Another option would be to focus on a known physiologic differences which might shed light on pathologic mechanisms e.g. gender and the influences of obesity and atrial fibrillation.

MedicalResearch.com Interview with: Gregory YH Lip MD, FRCP (London, Edinburgh, Glasgow), DFM, FACC, FESC Professor of Cardiovascular Medicine, Adjunct Professor of Cardiovascular Sciences, Thrombosis Research Unit, Aalborg University, Denmark; Aston Centre for Cardiovascular Sciences City Hospital Birmingham England UK Medical Research: What is the background for this study? What are the main findings? Prof. Lip: Women with atrial fibrillation are at higher risk of stroke than men with atrial fibrillation. The reasons for this elevated risk remain unclear. The results from our worldwide study suggest that women are treated no differently to men in terms of anticoagulant therapy for stroke prevention. Thromboprophylaxis was, however, suboptimal in substantial proportions of men and women, with underuse in those at moderate-to-high risk of stroke and overuse in those at low risk.

Judith Lichtman, PhD, MPH Associate Professor (with tenure) Chair, Department of Chronic Disease Epidemiology Yale School of Public Health New Haven, CT 06520-803MedicalResearch.com Interview with: Judith Lichtman, PhD, MPH Associate Professor (with tenure) Chair, Department of Chronic Disease Epidemiology Yale School of Public Health New Haven, CT 06520-803 Medical Research: What is the background for this study? What are the main findings? Dr. Lichtman: Heart disease in younger women (18-55 years of age) is relatively rare, and represents less than 5% of all heart disease in women; however, young women who present with a heart attack are twice as likely to die in the hospital as compared with a similarly aged man, and this excess mortality risk continues beyond the index event. Delays in seeking prompt care has been suggested as one potential cause for the excess mortality in young women. We were interested in learning about the recognition of symptoms, perceived risk of heart disease, decision-making process to seek medical care, and interactions with the healthcare system among young women who recently had a heart attack. We found that even though the majority of young women presented with chest pain, they also experienced many other symptoms such as fatigue, nausea, muscle pain, and weakness. They commonly attributed symptoms to non-cardiac conditions because they felt they did not experience the “Hollywood Heart Attack” that is commonly portrayed in the media. Interestingly, despite reporting a strong family history of cardiac disease, and having multiple risk factors, many of the women we spoke with did not perceive they were at risk for heart disease, and many were not working with their physicians to manage their risk factors. They were also concerned about being seen as a hypochondriac if they reported their symptoms. Finally, women reported that the healthcare system was not consistently responsive when they reported their symptoms.

Jennifer L. Cook, MD FAHA Assistant Professor of Medicine | Heart Failure and Transplantation Medical Director Left Ventricular Assist Device Program Medical University of South Carolina Charleston, SC 29425MedicalResearch.com Interview with: Jennifer L. Cook, MD FAHA Assistant Professor of Medicine | Heart Failure and Transplantation Medical Director Left Ventricular Assist Device Program Medical University of South Carolina Charleston, SC 29425 Medical Research: What is the background for this study? What are the main findings? Dr. Cook: Although the incidence of heart failure is similar in men and women, women are more likely to die from it.  Despite this fact a common misperception persists that men are at greater risk.  Although advanced therapies such as mechanical support are as effective in women as in men, women are less likely to receive mechanical support.  In clinical trials investigating mechanical support as a bridge to transplant less than 30% of patients were women.  In trials investigating mechanical support for patients ineligible for heart transplant even fewer were women, less than 20%.  . Medical Research: What should clinicians and patients take away from your report? Dr. Cook: It has been shown that women with heart failure are more likely to remain under the care of a primary physician instead of being referred for specialized cardiovascular care.  The explanation for this pattern is not understood.  It is important to raise awareness and emphasize the high risk of heart failure mortality among women.
