Dr Amitava Banerjee NIHR Clinical Lecturer in Cardiovascular Medicine University of Birmingham UK MedicalResearch.com Interview with: Dr Amitava Banerjee NIHR Clinical Lecturer in Cardiovascular Medicine University of Birmingham UK MedicalResearch.com: What are the main findings of the study? This was the first long-term study in individuals with atrial fibrillation to consider the impact of renal function, as measured by eGFR, on stroke/thromboembolism, mortality and bleeding in the same population concurrently. Answer: There were three main findings of our study.
  • First, patients with worsening renal function had more severe risk factor profiles and had higher rates of stroke/thromboembolism, mortality and bleeding.
  • Second, individuals receiving oral anticoagulation had lower rates of stroke/thromboembolism and mortality than those not receiving anticoagulation at all levels of renal function measured by eGFR, suggesting that anticoagulation has benefit in even patients with low eGFR.
  • Third, renal function was not an independent predictor of stroke/thromboembolism at 1 year after adjustment for baseline characteristics.

MedicalResearch.com Interview with: M Mushfiqur Rahman, MSc. PhD candidate School of Population and Public Health University of British Columbia, Statistical Analyst Arthritis Research Centre of Canada 5591 No. 3 Road, Richmond BC, Canada, V6X 2C7; MedicalResearch.com:  What are the main findings of the study? Author’s response: Using 18 years of administrative health records from British Columbia, Canada, our aim was to determine whether osteoarthritis increases the risk of cardiovascular disease in a longitudinal study. We also examined the risks of specific cardiovascular conditions such as, myocardial infarction, ischemic heart disease, congestive heart failure, and stroke after adjusting for age, sex, socio-economic status, diabetes, hypertension, hyperlipidemia, chronic obstructive pulmonary disease, and a co-morbidity score. We observed a significant increase in the risk of cardiovascular disease, ischemic heart disease, and congestive heart failure among individuals with osteoarthritis compared with age-sex matched non-osteoarthritis individuals. Our data suggests that adult women and men aged 65 years and older with osteoarthritis had higher risks of developing these conditions. The risks were also higher among severe osteoarthritis patients who had undergone total joint replacement surgeries. Men aged between 20-64 years with osteoarthritis did not show higher risks of developing these conditions.

MedicalResearch.com Interview with: Masato Tsutsui, MD, PhD, FAHA Professor and Chairman Department of Pharmacology Graduate School of Medicine University of the Ryukyus Okinawa 903-0215, Japan MedicalResearch.com: What are the main findings of the study? Dr. Tsutsui: A recent large prospective study reported that coffee consumption is associated with reduced mortality for cardiovascular disease (NEJM 2012).  However, its precise mechanisms remain to be clarified.  Our double-blind, placebo-controlled, crossover study demonstrated, for the first time, that caffeine contained in a cup of coffee ameliorates microvascular endothelial function in healthy individuals.  These findings may explain, at least in part, the association of coffee consumption with reduced mortality for cardiovascular disease.

Carlos Lorenzo, MD Department of Medicine, University of Texas Health Science Center 7703 Floyd Curl Drive San Antonio, Texas 78229MedicalResearch.com Interview with: Carlos Lorenzo, MD Department of Medicine, University of Texas Health Science Center 7703 Floyd Curl Drive San Antonio, Texas 78229 MedicalResearch.com: What are the main findings of the study? Dr. Lorenzo: Metabolically healthy obese individuals are at increased risk of developing of diabetes and cardiovascular disease. These findings were demonstrated in men and women and in Mexican Americans and non-Hispanic whites. Management of excess weight and any metabolic abnormality appears to be important for all individuals. Our study is also in agreement with previous studies that indicate that metabolically unhealthy normal weight individuals are at increased risk of developing of diabetes and cardiovascular disease.

MedicalResearch.com Interview with: Prof. Prashanthan SandersMedicalResearch.com Interview with: Prof. Prashanthan Sanders Director, Centre for Heart Rhythm Disorders University of Adelaide | Royal Adelaide Hospital | SAHMRI NHMRC Practitioner Fellow Centre for Heart Rhythm Disorders Department of Cardiology | Royal Adelaide Hospital Adelaide 5000 | Australia MedicalResearch.com: What are the main findings of the study? Answer: Aggressive treatment of risk factors and weight reduced the symptom burden associated with atrial fibrillation. It is therefore important that in a similar manner to how we treat coronary artery disease, in atrial fibrillation there should be management directed at the reasons why these individuals got AF in the first place.

MedicalResearch.com Interview with: Nina Berentzen Centre for Nutrition, Prevention and Health Services National Institute for Public Health and the Environment Bilthoven The Netherlands MedicalResearch.com: What are the main findings of the study? Answer: This study in 11-12 year old children shows that self-reported characteristics of sleep quality were not associated with blood pressure and HbA1c; and that in girls, but not in boys, some sleep characteristics were associated with anthropometric outcomes (BMI, waist circumference) and cholesterol levels. More specifically, in girls, longer time in bed was associated with lower BMI and waist circumference; having night-time awakenings with higher total cholesterol, going late to bed while rising early with higher total and HDL cholesterol; and feeling sleepy/tired during daytime with lower HDL cholesterol and with higher total-to-HDL cholesterol ratio. We report new findings for daytime outcomes of sleep quality that were not studied before in relation to cardiometabolic risk; e.g. difficulty with getting up in the morning, feeling rested after waking, and feeling sleepy or tired during the day. Our study therefore offers insight not only in characteristics of sleep at night, but also in consequences of sleep during the day.

MedicalResearch.com interview with: Martha Mullett, MD MPH Neonatology West Virginia Universty Ped&Neo 1 Medical Center Dr Morgantown, WV 26506Martha Mullett, MD MPH Neonatology West Virginia Universty Ped&Neo 1 Medical Center Dr Morgantown, WV 26506   MedicalResearch.com: What are the main findings of the study? Dr. Mullett: The unique findings in this study relate to differences in triglycerides (TG) in premature infants and small for gestational age (SGA) infants when in 5th grade, at which time the children are approximately 11 years old.  Premature infants have higher triglyceride levels in 5th grade than term infants.(p<.05)  This difference appears in those premature infants who become overweight/obese by this age, but this reaches only a trend level. (p=.058) SGA infants who become overweight/obese by 5th grade (BMI ≥ 85th percentile) have TG that are significantly higher than all other 5th grade groups.

Joshua Lewis, Ph.D Raine Foundation / Alan Robson Fellow Bone and Vascular Research Group School of Medicine and Pharmacology University of Western Australia Department of Endocrinology and Diabetes Sir Charles Gairdner Hospital Hospital Avenue, Nedlands 6009MedicalResearch.com Interview with: Joshua Lewis, Ph.D Raine Foundation / Alan Robson Fellow Bone and Vascular Research Group School of Medicine and Pharmacology University of Western Australia Department of Endocrinology and Diabetes Sir Charles Gairdner Hospital Hospital Avenue, Nedlands 6009 www.boneandvascularresearch.org.au MedicalResearch.com: What are the main findings of the study? Dr. Lewis: The paper reports the findings from an ancillary study of the effects of 1200 mg per day of calcium supplementation on a major predictor of heart disease risk, carotid artery intima-medial thickness and atherosclerosis. The principle study was a large five-year double blind randomized controlled trial of calcium supplements or a placebo. After 3 years of calcium supplementation or placebo measures of carotid artery intima-medial thickness were identical in the placebo and calcium treated patients.  Atherosclerotic plaque was reduced in calcium treated patients when analysed as total calcium intake. These findings argue strongly against an adverse effect of high dose calcium tablets on cardiovascular risk.

Elsayed Z Soliman MD, MSc, MS, FAHA, FACC Director, Epidemiological Cardiology Research Center (EPICARE) Wake Forest School of Medicine Medical Center Blvs, Winston Salem, NC 27157MedicalResearch.com Interview with: Elsayed Z Soliman MD, MSc, MS, FAHA, FACC Director, Epidemiological Cardiology Research Center (EPICARE) Wake Forest School of Medicine Medical Center Blvs, Winston Salem, NC 27157 Atrial Fibrillation and the Risk of Myocardial Infarction MedicalResearch.com: What are the main findings of the study? Dr. Soliman: Using data from the REGARDS study, one of the largest US cohorts, we examined the risk of incident myocardial infarction (MI) associated with atrial fibrillation (AF). Overall, AF was associated with almost double the risk of MI. When we adjusted for common cardiovascular risk factors and potential confounders, the risk remained significantly high; about 70% increased risk. When we looked at women, men, blacks, and whites separately,  we found significant differences between races and sex.  AF in women and blacks was associated with more than double the risk of MI. This compares to less than 50% increased risk of heart attack associated with AF in men and whites . So AF is basically bad for all, but the risk of MI associated with AF is more pronounced in women and blacks.

MedicalResearch.com Interview with: Lotta Ljung, MD, PhD Umeå University, Umeå and Karolinska  Institute Stockholm, Sweden MedicalResearch.com: What are the main findings of the study? Dr. Ljung:  In this observational study we observed a lower risk of acute coronary syndromes in a cohort of patients with rheumatoid arthritis (RA) exposed to tumor necrosis factor inhibitors (TNFi) compared with the risk among patients without this exposure. The adjusted relative risk (HR) was 0.73-0.82  among TNFi exposed patients compared with the biologics-naive RA cohort, depending on the time frame evaluated, which can be concluded as a moderately lower risk. Compared with the risk in the general population, the risk in RA patients was higher, whether exposed to TNFi or not.

MedicalResearch.com Interview with: Marcin Sadowski Świętokrzyskie Cardiology Center, Kielce, Poland MedicalResearch.com: What are the main findings of the study? Dr. Sadowski: In multivariable analysis, diabetes was an independent risk factor of in-hospital and 1-year mortality in women treated for STEMI. In women with STEMI and diabetes one-year mortality was significantly lower in those treated with primary percutaneous coronary intervention than in those on optimal medical therapy. Early and long-term prognoses after STEMI were the worst in diabetic women, compared with non-diabetic women and diabetic men.

MedicalResearch.com Interview wit: Elin Strand

Researcher, Department of Clinical Science University of Bergen, Norway MedicalResearch.com: What are the main findings of this study? Answer: The main findings in this prospective observational cohort study among patients with established coronary artery disease were that a very high intake of omega-3 fatty acids was associated with a reduced risk of acute myocardial infarction in patients with diabetes, but with an increased risk of fatal acute myocardial infarction and with lower glycosylated hemoglobin in those without impaired glucose metabolism.

Jelena Kornej Department of Electrophysiology, Heart Center, University of Leipzig, Leipzig, Germany & University of Birmingham Centre for Cardiovascular Sciences, City Hospital, Birmingham, United Kingdom MedicalResearch.com: What are the main findings of the study? Answer: The main finding of our analysis was that thromboembolic events after atrial fibrillation (AF) catheter ablation are rare, but all three stroke risk stratification scores, i.e. CHADS2, CHA2DS2-VASc, and R2CHADS2 were associated with thromboembolic risk in anticoagulated population. Furthermore, patients with AF recurrences had increased risk for thromboembolic complications.

Saul Blecker, MD, MHS Department of Population Health, NYU School of Medicine, New York, NY Department of Medicine, NYU School of Medicine, New York, NYMedicalResearch.com Interview with: Saul Blecker, MD, MHS Department of Population Health, NYU School of Medicine Department of Medicine, NYU School of Medicine, New York, NY   MedicalResearch.com: What are the main findings of the study? Dr. Blecker: Inpatient quality of care has focused primarily on patients with acute heart failure, commonly identified by principal discharge diagnosis code. However, patients with heart failure are commonly hospitalized for other causes and should benefit from many of the same treatments. We found that in our sample, as compared to patients with a principal diagnosis of heart failure, heart failure patients hospitalized with a non–heart failure diagnosis had lower rates of guideline-concordant care, including assessment of left ventricular function and prescription for an ACE inhibitor or ARB, at time of discharge. This is important as our study suggests that these therapies were associated with reduced mortality for patients hospitalized with heart failure, regardless of the reason for hospitalization.

Prof. Dr. Gunnar Brix Division of Medical and Occupational Radiation Protection Federal Office for Radiation Protection Institut für Med. Strahlenhygiene 85764 NeuherbergMedicalResearch.com: Prof. Dr. Gunnar Brix Division of Medical and Occupational Radiation Protection Federal Office for Radiation Protection Institut für Med. Strahlenhygiene 85764 Neuherberg MedicalResearch.com:  What are the main findings of the study? Answer: We investigated the cumulative radiation exposure and cancer risk of more than 1200 patients with ischemic heart diseases (IHD) from diagnostic and therapeutic imaging procedures performed 3 month before and 12 month after the date of diagnosis. The major findings were:
  • ­    87% of patient exposure resulted from heart catheter procedures.
  • ­    The average cumulative effective dose was 13.3 mSv in males and 10.3 mSv in females. The highest dose was nearly 100 mSv.
  • ­    The estimated average attributable life-time risk of male and female patients to develop a radiation-induced cancer in their remaining life was 0.09 % and  0.07 %, respectively. This correspond to 1 excess cancer in about 1100 male and 1400 female IHD patients. The highest risk was 0.9 %.
  • ­ The effective dose is inadequate to characterize individual radiation risks, since neither the age nor the sex of the patient is taken into account. According to our results, cancer risks can vary by a factor of more than 10 for comparable values of the effective dose.

MedicalResearch.com Interview with: Christian K. Roberts Exercise and Metabolic Disease Research Laboratory, Translational Sciences Section, School of Nursing University of California, Los Angeles, CA MedicalResearch.com: How would you best summarize the main findings/results of this study? Answer: Our main finding was that HDL functioned better in its antioxidant role in subjects who participated in resistance exercise training (i.e. weight training) a minimum of 4 days a week, regardless of their weight—one group was lean (BMI <25) and the other overweight/obese (BMI >27) —than those who didn’t exercise (overweight, BMI >27, and untrained). In addition, HDL had similar effectiveness as an antioxidant in the overweight-trained group as in the as lean-trained group. Although indices of weight were associated with dysfunctional HDL, differences in fitness may be a better measure of who has healthier functioning HDL.

Ankur Pandya PhD Assistant Professor of Public Health in the Division of Health Policy Department of Public Health at Weill Cornell Medical CollegeMedicalResearch.com Interview with: Ankur Pandya PhD Assistant Professor of Public Health in the Division of Health Policy Department of Public Health at Weill Cornell Medical College MedicalResearch.com: What are the main findings of the study? Dr. Pandya: Our study looked at the impact of some of the future risk factors for cardiovascular disease in the United States.  Using nine National Health and Nutrition Examination Survey waves from 1973 to 2010 we forecasted disease risk and prevalence from 2015 to 2030. We found that despite continued improvements in the disease’s treatment and declining smoking rates, increasing obesity rates, the aging population, and declining mortality from the disease should cause a rise in health care costs, disability, and reductions in the quality of life associated with increased disease prevalence.

Anil K. Sood MD Department of Gynecologic Oncology The University of Texas MD Anderson Cancer Center Unit 1362, PO Box 301439, Houston, TX, 77030MedicalResearch.com Interview with: Anil K. Sood MD Department of Gynecologic Oncology The University of Texas MD Anderson Cancer Center Unit 1362, PO Box 301439, Houston, TX, 77030 MedicalResearch.com: What are the main findings of the study? Dr. Sood: For women with newly diagnosed ovarian cancer, high heart rate at diagnosis (tachycardia), venous thromboembolism (VTE) occurring after diagnosis and pulmonary hypertension post-diagnosis are independently related to reduced survival after controlling for tumor stage, grade, and extent of cytoreduction.  Women with tachycardia lived an average of 4.0 years after diagnosis compared with 5.9 years for women without tachycardia, a 32% reduction in duration of survival.  Patients who experienced VTE lived a median 4.1 years after diagnosis, compared with 6.4 yrs for patients who did not experience VTE.

Answer: Our main findings from this nationwide study are that during a 10-year period where several national initiatives were taken to increase bystander CPR and improve advanced care, bystander CPR increased more than a two-fold from 21 % in 2001 to 45% in 2010. In the same period survival on arrival at the hospital increased more than a two-fold from 8% in 2001 to 22% in 2010, and 30-day survival more than a three-fold from 3.5% in 2001 to 11% in 2010.

Dr. Afshin Farzaneh-Far, M.D. University of Illinois at ChicagoMedicalResearch.com Interview with: Dr. Afshin Farzaneh-Far, M.D. University of Illinois at Chicago MedicalResearch.com: What are the main findings of the study? Answer: Traditionally SPECT MPI has been performed with adenosine which has a significant body of published prognostic data. Regadenoson is a selective A2A receptor agonist and is now the stress agent most widely used in the United States. Unlike adenosine, regadenoson is given as a bolus rather than as an infusion, simplifying the testing protocol and is better-tolerated. However, despite increasing use of regadenoson, there is very limited data on risk prediction using this agent. This study showed that the ability of SPECT MPI to predict heart attacks and death is the same for the new stress agent Regadenoson as it is for the old agent Adenosine.

Dr. Satyam Sarma MD Assistant Instructor, Cardiology University of Texas, Southwestern Medical Center Inst. for Exercise and Environmental Medicine 7232 Greenville Ave. Dallas TX 75231MedicalResearch.com Interview with: Dr. Satyam Sarma MD Assistant Instructor, Cardiology University of Texas, Southwestern Medical Center Inst. for Exercise and Environmental Medicine 7232 Greenville Ave. Dallas TX 75231 MedicalResearch.com: What are the main findings of the study? Dr. Sarma: The main findings of our study were that as we age or live a sedentary lifestyle, fat tends to accumulate in the muscle of the heart. The accumulation of myocardial lipids were linked to abnormalities in diastolic function. With increasing levels of fat, the left ventricle became less distensible and had impaired tissue relaxation.

MedicalResearch.com Interview with: Mackram Eleid, MD Division of Cardiovascular Diseases and Internal Medicine MedicalResearch.com: What are the main findings of the study? Dr. Eleid: Our study investigated the characteristics, outcomes and impact of aortic valve replacement in a large series of 1704 patients with severe aortic stenosis (aortic valve area < 1 cm2) and preserved ejection fraction (EF > 50%) according to the flow-gradient classification that incorporates both stroke volume index and mean aortic valve gradient.  The primary findings were that patients with low flow, low gradient AS have lower survival than other flow-gradient patterns (a 3.2-fold increase risk of mortality compared to normal flow, low gradient), and their survival is improved with aortic valve replacement.  Conversely, patients with normal flow and low gradient had a favorable survival with medical management, suggesting a less advanced stage of disease compared to the other groups.  Additionally, a novel observation from this study is that patients with low flow had a higher prevalence of atrial fibrillation and previous heart failure events compared to other groups.

MedicalResearch.com Interview with: Dr Anoop Shah MBChB Cardiology Research fellow Centre of Cardiovascular sciences Chancellors Building University Of Edinburgh Little France Edinburgh MedicalResearch.com: What are the main findings of the study? Answer: Many studies have shown the effect of air pollution on cardiac mortality and myocardial infarction. Less studies have shown a similar effect on patients with heart failure. We therefore systemically reviewed and pooled data across 12 countries involving over 4 million patients with heart failure. We showed that air pollution has a close temporal association with either being hospitalized or dying from heart failure. Most of the effects of air pollution on patients with heart failure were acute. Most of the data that we analyzed came from developed countries across Europe and the USA. There was a  significant paucity of data from rapidly urbanizing nations such as India and China.

DeBakey Department of Surgery, Baylor College of Medicine, Houston, TexasThe Michael E. DeBakey Veterans Affairs Medical Center, Houston, Texas Department of Cardiovascular Surgery, The Texas Heart Institute at St. Luke’s Episcopal Hospital, Houston, Texas   MedicalResearch.com: What are the main findings of the study? Dr. Bakaeen:  The relative use of off-pump CABG peaked at 24% in 2003, followed by a slow decline after that to about 19%. In addition, the conversion rate from off- to on-pump decreased with time and has stayed below 3.5% in recent years. Perioperative mortality rates decreased over time for both on- and off-pump CABG and have stayed below 2% since 2006. The mortality associated with converted cases was high regardless of the surgery year.

MedicalResearch.com Interview with: Elisa Ebrille, MD Department of Cardiology, School of Medicine Fiorenzo Gaita, M.D. Director Division of Cardiology Department of Medical Sciences University of Turin, Turin, Italy MedicalResearch.com What are the main findings of the study? Answer: We evaluated 33 patients with long-standing atrial fibrillation and valvular heart disease who underwent valve surgery and concomitant cryoablation (pulmonary veins isolation, mitral isthmus and roof line lesions) from 2000 to 2002. The surgically created ablation lesion was validated with electroanatomic mapping. Percutaneous radiofrequency ablation was performed in cases with lesion incompleteness and these patients were followed for over 10 years.
  • A hybrid approach, combining surgical ablation procedure consisting of pulmonary veins isolation and creation of left atrial linear lesions (mitral isthmus and roof lines), along with endocardial ablation, when necessary, led to a significant clinical improvement in patients with long-standing atrial fibrillation and valvular heart disease during a long-term follow-up (> 10 years).
  • With the hybrid approach, pulmonary veins isolation and transmural left atrial linear lesions were obtained in a high percentage of patients (79%). When achieved and electrophysiologically demonstrated, the complete ablation scheme was effective in more than 80% of patients in maintaining sinus rhythm throughout follow-up.
