MedicalResearch.com Interview with: Peter Ganz, MD Chief, Division of Cardiology Director, Center of Excellence in Vascular Research Zuckerberg San Francisco General Hospital Maurice Eliaser Distinguished Professor of Medicine University of California, San Francisco MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Ganz:  The research described in the JAMA paper involved measuring 1,130 different proteins in nearly 2000 individuals with apparently stable coronary heart disease, who were followed up to 11 years. Initially, two hundred different proteins were identified whose blood levels could be related to the risk of heart attacks, strokes, heart failure and death, and ultimately a combination of nine proteins was selected for a risk prediction model, based on their combined accuracy and sensitivity. Application of these findings to samples of patients with stable coronary heart disease demonstrated that some of those who were deemed clinically stable instead had a high risk of adverse cardiovascular outcomes, while other patients with the same clinical diagnosis had a very low risk. Thus, individuals who all carried the same clinical diagnosis of stable coronary heart disease had a risk of an adverse cardiovascular event that varied by as much as 10-fold, as revealed by analysis of the levels of the nine proteins in their blood. Given such large differences in risk and outcomes, patients could reasonably opt to be treated differently, depending on their level of risk. We hope that in the future, management of patients with stable angina will at least in part rely on risk assessment based on levels of blood proteins. (more…)

MedicalResearch.com Interview with: Mikhail Kolonin, PhD, Associate Professor Director, Center for Metabolic and Degenerative Diseases Harry E. Bovay, Jr. Distinguished University Chair in Metabolic Disease Research The Brown Foundation Institute of Molecular Medicine University of Texas Health Science Center at Houston Houston, TX 77030 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Epidemiology studies have indicated that in obese patients progression of prostate, breast, colorectal, and other cancers is more aggressive. Adipose (fat) tissue, expanding and undergoing inflammation in obesity, directly fuels tumor growth. Adipose tissue is composed by adipocytes and stromal/vascular cells, which secrete tumor-trophic factors. Previous studies by our group have demonstrated that adipose stromal cells, which support blood vessels and serve as adipocyte progenitors, are recruited by tumors and contribute to cancer progression. Mechanisms underlying stromal cell trafficking from fat tissue to tumors have remained obscure. We discovered that in obesity a chemokine CXCL1, expressed by cancer cells, attracts adipose stromal cells to tumors. (more…)

MedicalResearch.com Interview with: Fu Guosheng MD Professor and Chairman, Department of Cardiology Sir Run Run Shaw Hospital, College of Medicine Zhejiang University Hangzhou, China MedicalResearch.com: What is the background for this study? Response: Acute myocardial infarction (AMI) remains a major cause of long term morbidity and mortality worldwide. Although we can re-vascularize the occluded vessels by cardiac intervention or coronary artery bypass graft (CABG), it is not helpful for the damaged myocardium, which urges us to find a new therapeutic method. An increasing body of evidence from a wide range of experimental animal studies and clinical trials suggests that endothelial progenitor cell (EPC) transplantation can repair “broken” heart by involving direct angiogenesis and secreting protective paracrine factors, which has a bright prospect for clinical application. However, transplantation of autologous EPC has numerous limitations, including the limited supply of expanded EPC, the impaired function and activity of the transplanted cells, and so on. Therefore, it is desirable to develop novel proangiogenic strategies that improve the efficacy of EPC transplantation. (more…)

MedicalResearch.com Interview with: Dr. James V. Freeman MD Assistant professor of cardiology and Assistant Clinical Professor of Nursing Internal Medicine Yale School of Medicine MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Freeman: Randomized trials of left atrial appendage (LAA) closure with the Watchman device have shown varying results, and its cost-effectiveness compared to anticoagulation has not been evaluated using all available contemporary trial data. We used a Markov decision model to estimate lifetime quality-adjusted survival, costs, and cost-effectiveness of LAA closure with Watchman, compared directly with warfarin and indirectly with dabigatran, using data from the long-term (mean 3.8 year) follow-up of PROTECT AF and PREVAIL randomized trials. Using data from PROTECT AF, the incremental cost-effectiveness ratios (ICER) compared to warfarin and dabigatran were $20,486 and $23,422 per quality adjusted life year (QALY), respectively. Using data from PREVAIL, LAA closure was dominated by warfarin and dabigatran, meaning that it was less effective (8.44, 8.54, and 8.59 QALYs, respectively) and more costly. (more…)

MedicalResearch.com Interview with: Sahil Agrawal MD, MD Heart and Vascular Center St. Luke’s University Health Network Bethlehem, PA 18015 MedicalResearch.com: What is the background for this study? Dr. Agrawal: Patients admitted on a weekend have previously been known to have poorer outcomes compared to patients admitted on weekdays for various acute illnesses. With the advent of early fibrinolytic therapy and subsequently, emergent primary percutaneous coronary interventions (PCI), such discrepancies in outcomes have been largely resolved for ST-segment elevation myocardial infarctions (STEMI). In contrast, treatment of non-ST segment elevation myocardial infarction (NSTEMI) has remained less stringent such that invasive coronary angiography and potential intervention is often delayed for those presenting on a weekend rather than a week day. According to current ACC/AHA guidelines for NSTEMI, an early invasive strategy (EIS) is the preferred method of management unless barred by presence of contraindications (comorbid conditions) or patients’ preference. We were interested in investigating differences in utilization of EIS between patients admitted on a weekend versus those admitted on a weekday for an NSTEMI, and to evaluate the impact of such differences on in-hospital mortality in such patients.

MedicalResearch.com Interview with: Ian Kronish, MD, MPH Florence Irving Assistant Professor of Medicine Center for Behavioral Cardiovascular Health Columbia University Medical Center MedicalResearch.com: What is the background for this study? Dr. Kronish: Prior studies have shown that adherence to statins is suboptimal both in patients prescribed statins for primary prevention and in high-risk patients who are prescribed statins to prevent recurrent events. But, to our knowledge, prior studies had not examined the impact of a hospitalization for a myocardial infarction (MI) on subsequent adherence to statins. We wondered whether the hospitalization would serve as a wake-up call that led patients to become more adherent after the MI. At the same time, we were concerned that the physical and psychological distress that arises after a hospitalization for an MI may lead to a decline in statin adherence. (more…)
AHA Journals, Author Interviews, CT Scanning, Diabetes, Heart Disease / 17.06.2016

MedicalResearch.com Interview with: Prof. David A. Halon MB ChB, FACC, FESC Associate Professor of Clinical Medicine Technion, Israel Institute of Technology. Director, Interventional Cardiology Lady Davis Carmel Medical Center Haifa, Israel MedicalResearch.com: What is the background for this study? Prof. Halon: Type 2 diabetics are well known to have more cardiovascular events than non-diabetics but even among diabetics this risk is heterogeneous and some remain at very low risk. It remains uncertain if additional diagnostic modalities over and above clinical risk scores may be helpful in defining which diabetics are at high risk for an adverse event. We performed a study using cardiac CT angiography (CCTA) in 630 type 2 diabetics 55-74 years of age with no history of coronary artery disease to examine if CTA findings would have additional prognostic value over traditional risk scores for cardiovascular or microvascular based events over 7.5 years of follow-up.

Author Interviews, Heart Disease, Kidney Disease / 15.06.2016

MedicalResearch.com Interview with: Burns C. Blaxall, PhD, FAHA, FACC, FAPS Director of Translational Science, Heart Institute Co-Director, Heart Institute Research Core & Biorepository Professor, UC Department of Pediatrics MedicalResearch.com: What is the background for this study? Dr. Blaxall: The development of kidney disease subsequent to chronic heart failure is known clinically as cardiorenal syndrome 2, and is associated with dual organ failure and reduced survival. Furthermore, patients undergoing invasive cardiac procedures that require heart-lung bypass are at significant risk for developing kidney injury. According to the National Kidney Foundation, cardiorenal syndrome 2 presents a considerable economic burden of around $30 billion annually. Previous work has demonstrated the role of G protein-coupled receptor (GPCR) signaling and the activation of G protein βγ (Gβγ) subunits in the development and progression of heart failure, however little is known regarding the role of this signaling pathway in kidney disease.

MedicalResearch.com Interview with: Torsten Dahlén MD Centre for Hematology Karolinska University Hospital Solna Stockholm Sweden MedicalResearch.com: What is the background for this study?  Dr. Dahlén: Patients diagnosed with CML have had a dramatic increase in life-expectancy since the widespread introduction of tyrosine kinase inhibitors (TKI) in 2001. However, treatment is today regarded as life-long. We thus need to observe for late-effects of continuous TKI exposure. Recent reports have demonstrated a linkage between TKI treatment, especially more potent 2nd and 3rd generation drugs, and to the occurrence of peripheral arterial occlusive disease (PAOD). This study aimed to use real-world data utilizing Swedish population based registries together with the dedicated Swedish CML registry which contains data and follow-up on more than 98% of all CML patients diagnosed in Sweden since 2002.

Author Interviews, Blood Pressure - Hypertension, Heart Disease, JACC / 14.06.2016

MedicalResearch.com Interview with: Duk-Woo Park, MD, PhD Division of Cardiology, Asan Medical Center University of Ulsan College of Medicine and National Evidence-based Healthcare Collaborating Agency Seoul, Republic of Korea MedicalResearch.com: What is the background for this study? What are the main findings? Response: Currently, less restrictive blood pressure (BP) target by the 2014 hypertension guidelines (JNC-8) and more intensive BP target of the SPRINT is now conflicting, which causes uncertainty and confusion among clinicians. In our study, the proportion of persons who would meet the SPRINT BP goals is substantially less than those who would meet the 2014 guideline blood pressure goals. There is a positive association between the risk of major cardiovascular events and increasing levels of BP control status under different 2014 guideline and SPRINT criteria. Our study reconfirmed the findings of the SPRINT trials in real-world population. (more…)

MedicalResearch.com Interview with: Marko Mornar Jelavic, MD, PhD Department for Internal Medicine and Dialysis Health Center Zagreb Zagreb, Croatia MedicalResearch.com: What is the background for this study? Response: Zagreb is the capital and the largest city of the Republic of Croatia which is placed in South-Eastern Europe. The wider Zagreb metropolitan area has the total population of up to 1.2 million (20% of the total Croatia’s population). The climate of Zagreb is classified as a humid continental. The average daily mean temperature in winter is around +1 °C (from December to February) and the average temperature in summer is 22.0 °C. For the first time, we wanted to investigate whether particles of dimensions ≤10 micrometers (PM10) nitrogen dioxide (NO2) and ozone (O3), as well as certain meteorological conditions (air temperature, humidity and pressure) have any impact on appearance of myocardial infarction (MI) in the region with a humid continental climate.

MedicalResearch.com Interview with: Joshua J. Joseph, MD Christopher D. Saudek M.D. Fellow in Diabetes Research Division of Endocrinology, Diabetes and Metabolism Johns Hopkins University School of Medicine MedicalResearch.com: What does your study explore? Response: Our study explores two basic questions: (a) Are multi-ethnic people with higher levels of cardiovascular health less likely to develop diabetes based on the AHA ideal cardiovascular health metric? (b) Do these associations vary by race/ethnicity (non-Hispanic white, Chinese American, African American, and Hispanic American)? MedicalResearch.com: Why did you choose this topic to explore? Response: The literature has shown a strong association between lifestyle factors and elevated risk of diabetes in majority non-Hispanic white studies. One study of American Indians showed that meeting a greater number of ideal cardiovascular health goals was associated with a reduced risk of diabetes. We aimed to assess the association of baseline ideal cardiovascular health with incident diabetes within a multi-ethnic population, due to variation of ideal cardiovascular health by race/ethnicity.

MedicalResearch.com Interview with: Alexander Egeberg, MD PhD Gentofte Hospital Department of Dermatology and Allergy Denmark MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Egeberg: While psoriasis has been associated with an increased risk of cardiovascular disease (CVD), studies have generally neglected to adjust for family history of CVD which is a well-established cardiovascular risk factor. In a population-based study of young patients with psoriasis, we found an increased risk of CVD only in patients with a positive family history of CVD but not in those patients that did not have a positive family history.

MedicalResearch.com Interview with: Dr Ramon Estruch, MD PhD Senior Consultant in the Internal Medicine Department of the Hospital Clinic Barcelona MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Estruch: Although weight stability requires a balance between calories consumed and calories expended, it seems that calories from vegetable fats have different effects that calories from animals on adiposity. Thus, an increase of dietary fat intake (mainly extra virgin olive oil or nuts) achieved naturally in the setting of Mediterranean diet does not promote weight gain or increase in adiposity parameters such as waist circumference.

MedicalResearch.com Interview with: Giovanni Esposito MD, PhD Associate Professor of Cardiology Department of Advanced Biomedical Sciences Federico II University, Naples Napoli - Italy and Giuseppe Gargiulo, MD PhD Student Federico II University of Naples, Italy
MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Esposito: Aortic stenosis (AS) is the most frequent type of valvular heart disease in Europe and North America. As soon as symptoms occur, the prognosis of severe AS is poor, with majority of patients dying within 2 to 5 years. Unfortunately medical therapy of AS has no significant effects on patient survival, therefore the only treatment able to improve patient prognosis is valve replacement. Until 2002, the only treatment strategy was the surgical aortic valve replacement (SAVR). SAVR requires an open-heart procedure and cannot be offered to all patients with AS due to their advanced age and presence of comorbidities that make them inoperable or at high-risk for surgery. In the last decade, the less invasive percutaneous approach called transcatheter aortic valve implantation (TAVI) has demonstrated to be a valid alternative to SAVR for those patients deemed inoperable or at high risk for SAVR. After the first percutaneous intervention performed by Alain Cribier in 2002, TAVI has rapidly accumulated growing interest and enthusiasm that led to the first PARTNER trial guiding current guideline recommendations. Both American and European guidelines recommend to perform TAVI in all patients judged inoperable, and to consider TAVI as an alternative in high-risk patients, but with a Class IIb and a preference to SAVR. However, scientific evidence on TAVI exploded in the last few years, the guidelines cited are outdated (2014 and 2012 respectively), we have today 5 randomized trials and many other observational studies including patients with different pre-procedural risk (i.e lo-to-intermediate and high-risk), as well as long-term results of prior studies (i.e. 5-year follow-up of the PARTNER trial and 3-year of the US CoreValve trial), therefore we conducted a systematic review and meta-analysis comparing clinical outcomes, including short- and mid-term mortality, of adult patients with severe aortic stenosis undergoing either TAVI or SAVR with the aim to update this comparison and offer new perspectives.

MedicalResearch.com Interview with: Jeffrey M. Schussler, MD, FACC, FSCAI, FSCCT, FACP Baylor Scott & White Health Care System Cardiology: Baylor University Medical Center, Dallas, Tx Medical Director: CVICU Hamilton Heart and Vascular Hospital Professor of Medicine: Texas A&M School of Medicine MedicalResearch.com: What is the background for this study? Dr. Schussler: For the past few years, there has been an increased interest in performing coronary catheterization through the wrist. This is a technique that has been done (with great success and low complication rate) in other countries for years, with adoption rates >90% in some places. The US has been slower to adopt performing catheterization from the wrist, but the rate of using this approach has grown tremendously in the last 5 years. While less than 5% of all interventions were done using radial access previously, it now appraches 30% nationally. This increased rate of adoption been spurred on by studies which have shown lower incidences of complications, as well as some mortality benefit, and in particular in those patients who are highest risk for complications.

MedicalResearch.com Interview with: Dr. W.H. Wilson Tang M.D. Department of Cellular and Molecular Medicine (NC10) Cleveland Clinic Lerner Research Institute Cleveland, Ohio 44195 MedicalResearch.com: What is the background for this study? What are the main findings? Response: Our group has recently described the mechanistic link between intestinal microbe-generated phosphatidylcholine metabolite, trimethylamine N-oxide (TMAO), and the pathogenesis of atherosclerotic coronary artery disease (CAD) and its adverse clinical outcomes. Here in a separate, independent, contemporary cohort of patients undergoing coronary angiography, we demonstrated the association between elevated fasting TMAO levels and quantitative atherosclerotic burden (as measured by SYNTAX and SYNTAX II scores) in stable cardiac patients and is an independent predictor for the presence of diffuse (but not focal) lesion characteristics.

MedicalResearch.com Interview with: Dr. med. Johannes Neumann Resident physician University Heart Center Hamburg Department of General and Interventional Cardiology Universitätsklinikum Hamburg-Eppendorf Hamburg MedicalResearch.com: What is the background for this study? What are the main findings? Response: The early decision making in patients with suspected acute myocardial infarction is important. Current guidelines recommend measurement of cardiac troponin at admission and after 3 hours. In our study we evaluated the performance of a high-sensitivity troponin I assay with a rapid measurement after only 1 hour. We included 1040 patients with new onset chest pain and could show, that a low cutoff concentration of 6 ng/L after 1 hour allows safe rule-out of acute myocardial infarction. The results were comparable to the recommended 3-hour approach and were validated in 2 external cohorts. When using the 99th percentile to rule-out myocardial infarction, as recommended by current guidelines, the negative predictive value was much lower. Furthermore, a troponin I concentration above 6 ng/L in combination with an absolute change of 12 ng/L after 1 hour showed a high positive predictive value for the final diagnosis of myocardial infarction. This allows early decision making after only 1 hour. (more…)

MedicalResearch.com Interview with: Nicole Pratt PhD Senior Research Fellow Quality Use of Medicines and Pharmacy Research Centre Sansom Institute, School of Pharmacy and Medical Sciences University of South Australia Adelaide South Australia MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Pratt: The cardiac safety of methylphenidate has been debated. This study aimed to measure the risk of cardiac events in a large population of children treated with these medicines. We found that there was a significantly raised risk of arrhythmia in time periods when children were treated with methylphenidate compared to time periods when they were not. While the relative risk of cardiac events was significant the absolute risk is likely to be low as cardiac events are rare in children. (more…)

MedicalResearch.com Interview with: Dr. Nina Berentzen PhD National Institute for Public Health and the Environment Bilthoven, the Netherlands MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Berentzen: Cardiovascular disease and type 2 diabetes often occur together and share risk factors including an unhealthy diet, a lack of physical activity, and being overweight or obese. This study is the first to investigate the occurrence of both diabetes and CVD across two generations of parents and grandparents, and relate it to measurable risk factors in children. We found that one third of the 12-year-olds studied had a strong family history of one or both of cardiovascular disease (myocardial infarction and stroke) and type 2 diabetes. Children had a ‘strong family history’ if they had one affected parent, or at least one grandparent with early disease onset, or 3–4 grandparents with late disease onset. These children had higher levels of total cholesterol, and a higher ratio of total/HDL cholesterol than children with no family history of disease. (more…)

El Khoudary, Ph.D., M.P.H., Assistant professor 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: We studied 252 middle-aged women with no known cardiovascular disease from the Study of Women’s Health Across the Nation [SWAN] Heart Study to determine if 5 blood biomarkers associated with abnormal inflammation/hemostasis were associated with increasing amounts of calcium detected in coronary arteries on computed tomography scans, or coronary artery calcium progression. Only higher blood levels of plasminogen activator inhibitor-1 was associated with coronary artery calcium progression. (more…)

MedicalResearch.com Interview with: Steven Grinspoon, MD Professor of Medicine, Harvard Medical School MGH Endowed Chair in Neuroendocrinology and Metabolism Director, MGH Program in Nutritional Metabolism and Nutrition Obesity Research Center at Harvard MGH Boston, MA 02114 MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Grinspoon: Numerous epidemiologic studies have shown that people living with HIV face a 1.5 to 2-fold increased risk of heart attack, or myocardial infarction, as compared to individuals without the virus. Mechanisms underlying the increased risk of myocardial infarction in HIV are incompletely understood. It is possible that among people living with HIV, increased systemic immune activation fuels arterial inflammation. Arterial inflammation may, in turn, promote the development of high-risk morphology coronary atherosclerotic plaque, which is liable to rupture and result in myocardial infarction. For people diagnosed with HIV, the overall health benefits of immediate antiretroviral therapy (ART) are clear. However, the effects of newly-initiated antiretroviral therapy on arterial inflammation have not previously been studied. In this study, we set out to assess among a cohort of treatment-naive HIV-infected subjects, the effects of newly-initiated ART with a contemporary regimen on both immune function and arterial inflammation. We found that among treatment-naive HIV-infected individuals without clinical cardiovascular disease, newly initiated combined antiretroviral therapy has discordant effects to restore immune function without reducing the degree of arterial inflammation.

MedicalResearch.com Interview with: Norman C. Wang, M.D., M.S., Assistant professor University of Pittsburgh School of Medicine Samar R. El Khoudary, Ph.D., M.P.H., Assistant professor 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: We examined medical records, blood samples and heart CT scans for 372 black and white women from Pittsburgh and Chicago enrolled in the Study of Women’s Health Across the Nation (SWAN). The women averaged just over 51 years old, were not on hormone replacement therapy and had no known heart disease when enrolled. We then looked at blood levels of five biomarkers linked to inflammation. All of the biomarkers were associated with coronary artery calcification, a predictor of heart disease that is measured with a heart CT scan. Taking into account the participants’ body mass index (BMI), a measure of overall body fat, we found that obesity was a key factor linking most of the elevated inflammation biomarkers and coronary artery calcification. Regardless of BMI, black women with higher levels of one particular biomarker, C-reactive protein, were more likely to have coronary artery calcification than whites. In fact, black women with coronary artery calcification had an average level of C-reactive protein in their blood that was almost double that of their white counterparts. (more…)

MedicalResearch.com Interview with: Robert W. Levenson, Ph.D. Professor, Department of Psychology Director, Institute of Personality and Social Research (IPSR) University of California Berkeley, CA MedicalResearch.com: What is the background for this study? Dr. Levenson: This study comes from a 20-year longitudinal study of Bay Area married couples that we began in the late 1980s. The main purpose of the study was to understand the emotional qualities of successful marriages. Couples came to our laboratory every five years so that we could get a snapshot of the way they interacted with each. We also measured their psychological and physical health. This new paper connects the emotional behaviors we observed when couples discussed a problem in their marriage at the start of the study with the kinds of illnesses they developed over the ensuing decades.

MedicalResearch.com Interview with: Ingrid Elisabeth Christophersen MD PhD Postdoctoral research fellow Cardiovascular Research Center (CVRC) Massachusetts General Hospital MedicalResearch.com: What is the background for this study? What are the main findings? Dr. Christophersen: Several recent studies have utilized the CHA2DS2-VASc risk score to predict risk of atrial fibrillation (AF). However, the CHA2DS2-VASc was developed for prediction of stroke risk in patients with AF and has not been validated for prediction of AF risk. We have evaluated how well the CHA2DS2-VASc performed at predicting risk of AF compared with the most validated clinical risk score for AF - the CHARGE-AF risk score - in the Framingham Heart Study. We showed that the CHARGE-AF risk score performed better at predicting risk of AF than the CHA2DS2-VASc. (more…)
