MedicalResearch.com Interview with: Evan A Stein MD PhD FACC COO/CSO LIB Therapeutics Cincinnati. OH USA 45227 MedicalResearch.com: What is the background for this study? Response: Cardiovascular disease (CVD) remains the main cause of morbidity and mortality worldwide and is increasing in rapidly industrializing countries and is projected to cause more than >20 million deaths annually over the next 15 years. Low-density lipoprotein cholesterol (LDL-C) is well established as a major, easily modifiable, risk factor for CVD. Reductions with statins and, more recently, PCSK9 inhibitors, all agents which directly or indirectly upregulate the LDL receptor and enhance LDL-C clearance, have demonstrated CVD event reductions in cardiovascular outcome trials. Extensive data from these trials, provide a rough estimate that every 40 mg/dL reduction in LDL-C will reduce the risk of major CV cardiovascular events by 22% to 24%. Furthermore, trials with PCSK9 inhibitors added to statins which achieve substantial additional LDL-C reduction show and CVD event reduction remains linear to very low LDL-C levels without signals of adverse events. Based on this body of evidence, recent revisions to national and international guidelines, now advocate for greater LDL-C reductions and lower LDL-C treatment goals, for patients not achieving these goals on statins alone. The current consensus target goal for LDL-C in patients with CVD, or who are at very-high risk for of CVD, is now less than <55 mg/dL, and <70 mg/dL for those at high risk. This global trial of over 900 patients with CVD, or at very or high risk for CVD, on maximally tolerated statins assessed the 52-week efficacy and safety of monthly lerodalcibep. (more…)

MedicalResearch.com Interview with: Dr. Heather Tulloch, C. Psych Clinical, Health, and Rehabilitation Psychologist Division of Cardiac Prevention and Rehabilitation Associate Professor, Faculty of Medicine University of Ottawa Heart Institute MedicalResearch.com: What is the background for this study? Response: It is well established that many caregivers experience distress when caring for a loved one with cardiovascular disease. For example, over 40% of caregivers in Ontario, Canada, report high psychological, emotional, physical, social, and emotional stresses imposed by the caregiving role. Ironically, caregivers are vulnerable to developing their own poor cardiovascular health. For example, chronic stress brought on by a caregiving role increases caregivers’ cardiovascular reactivity (i.e., blood pressure, heart rate) and impaired endothelial function. Many caregivers also report poor preventative health behaviours and low quality of life scores. (more…)

MedicalResearch.com Interview with: Ambry GeneticsNancy Niguidula, MS, DPH Doctorate in Public Health in Toxicology Ambry Genetics   MedicalResearch.com: What is the background for this study? Response: The clinical presentations of many inherited cardiovascular conditions overlap; thus, genetic testing may clarify diagnoses, help with risk stratification, facilitate appropriate clinical management decisions, and aid in identifying asymptomatic, at-risk relatives. A large number of professional societies have developed practice guidelines and recommendations for genetic testing of cardiovascular diseases. These include international and collaborative expert panels that establish genetic screening and treatment recommendations by drawing on evidence-based medicine. To further strengthen the clinical utility of cardiovascular genetic testing, the American College of Medical Genetics and Genomics (ACMG) published a guideline for 59 genes with clinical actionability that should be reported if found on whole exome sequencing, even when unrelated to the testing indication.

MedicalResearch.com Interview with: Huan Song, PhD Center of Public Health Sciences, Faculty of Medicine, University of Iceland, Reykjavík, Iceland Department of Medical Epidemiology and Biostatistics Karolinska Institutet, Stockholm, Sweden MedicalResearch.com: What is the background for this study?   Response: Cardiovascular disease (CVD) presents a group of diseases that are common and sometimes fatal in general population. The possible role of stress-related disorders in the development of CVD has been reported. However, the main body of the preceding evidence was derived from male samples (veterans or active-duty military personnel) focusing mainly on posttraumatic stress disorder (PTSD) or self-reported PTSD symptoms. Data on the role of stress-related disorders in CVD in women were, until now, limited. Although incomplete control for familial factors and co-occurring psychiatric disorder, as well as the sample size restriction, limit the solid inference on this association, especially for subtypes of CVD.

MedicalResearch.com Interview with: Dr Vanessa Selak, MBChB, MPH, PhD, FAFPHM, FNZCPHM Senior Lecturer, Section of Epidemiology & Biostatistics School of Population Health Faculty of Medical and Health Sciences University of Auckland MedicalResearch.com: What is the background for this study? Response: In order to determine the balance of benefits and harms of aspirin in primary prevention there’s a need to know an individual’s risk of CVD and their risk of a major bleed without aspirin. We have lots of equations that can be used to determine, among people considering aspirin for primary prevention, an individual’s risk of CVD, but few bleeding risk equations that can be used to determine their risk of a major bleed. We sought to develop a bleeding risk equation that can be used to determine the risk of a major bleed among people in whom aspirin is being considered for the primary prevention of CVD. (more…)

MedicalResearch.com Interview with: Dr. Michael Barry MD Director of the Informed Medical Decisions Program Health Decision Sciences Center at Massachusetts General Hospital Physician at Massachusetts General Hospit Professor of Medicine,Harvard Medical School MedicalResearch.com: What is the background for this study? What are the main findings? Response: Cardiovascular disease (CVD), which can lead to heart attack and stroke, causes 1 in 3 deaths among adults in the United States. The Task Force reviewed the latest research on whether adding an electrocardiogram—or ECG, which is a test that records a person's heart activity—to the standard ways we measure CVD risk can help prevent heart attack and stroke in people who do not have symptoms and are generally healthy, as well as people who are already at risk for these conditions. The evidence shows that adding screening with ECG to the ways we already measure CVD risk is unlikely to help prevent heart attack or stroke in people at low risk. It can also cause harms—such as those from follow-on procedures like angiography and angioplasty, which can lead to heart attack, kidney failure, and even death. As a result, the Task Force recommends against screening with ECG for this group. For those who might benefit the most—people who are already at medium or high risk of CVD—there is not enough evidence to say whether or not adding screening with an ECG to standard care helps prevent heart attack and stroke. This is an area where we need more research.  (more…)

MedicalResearch.com Interview with: Nathalie Eckel, MSc German Diabetes Center Düsseldorf, Germany  MedicalResearch.com: What is the background for this study?  Response: Obesity is associated with metabolic disorders such as diabetes, high blood pressure and hypercholesterolemia, and with a higher risk of cardiovacular disease compared to normal weight. However, there is also the phenomenon of the so-called "metabolically healthy obesity" and "metabolically unhealthy normal-weight". So far it has been unclear how metabolic risk factors change over time in metabolically healthy people depending on body weight and what cardiovascular disease risk results from this. (more…)

MedicalResearch.com Interview with: “Pills Vitamins Macro April 22, 2012 4” by Steven Depolo is licensed under CC BY 2.0David J.A. Jenkins, MD, PhD, DSc Professor and Canada Research Chair in Nutrition and Metabolism Department of Nutritional Sciences University of Toronto  MedicalResearch.com: What is the background for this study? Response: The study was requested by the editor of JACC (Dr. Valentin Fuster) due to the widespread use of vitamin and mineral supplementation by the public and the requirement to know if there were any benefits or harms for cardiovascular disease. Our study was a follow-up to the US Preventive Services Task Force 2013 recommendations. (more…)

MedicalResearch.com Interview with: “Vegetarian Skewers” by Geoff Peters is licensed under CC BY 2.0Hana Kahleova, M.D., Ph.D. Director of clinical research Physicians Committee for Responsible Medicine Washington, DC 20016  MedicalResearch.com: What is the background for this study? What are the main findings?  Response: In this study, my research team and I reviewed multiple clinical trials and observational studies to determine the links between diet and cardiovascular disease (CVD) risk. We found that a healthy diet can reduce the risk of heart attack by more than 80 percent—something no drug has ever accomplished. We also found strong and consistent evidence that plant-based dietary patterns (with few or no animal products and rich in fruits, vegetables, grains, and legumes) can prevent and even reverse atherosclerosis and decrease other markers of CVD risk, including blood pressure, cholesterol, and weight. We found that a plant-based diet can reduce the risk of death from cardiovascular disease by about 40 percent overall.  (more…)

MedicalResearch.com Interview with: Dr Søren Skøtt Andersen and Dr Michelle Schmiegelow Study done in collaboration between Roskilde University Hospital and Gentofte University Hospital in Denmark. MedicalResearch.com: What are the main findings of the study? Answer: The main finding of this study of young women was that a body mass index above or equal to 25 kg/m2 in metabolically healthy women was not associated with an increased risk of cardiovascular events (myocardial infarction or ischemic stroke) within 5 years of follow-up. A BMI >= 25 kg/m2 in women with any metabolic disorder was associated with a 4-fold significant increased risk of the end-point. As increasing BMI is strongly associated with risk of developing metabolic disorders, the key message of this study is to stress the importance of preventing the development of metabolic disorders in overweight/obese women during this possible "window of opportunity".
