Medical Research: What are the main findings of the study?
Dr. Dregan: Our study showed that chronic inflammation was associated with increased risk of developing cardiovascular disease, specifically type II diabetes and coronary heart disease. The risk of cardiovascular disease increased with the severity of inflammatory disorders. In addition, inflammation also increased the risk of multiple morbidity (two or more cardiovascular diseases).
MedicalResearch.com Interview with: Jeff Trost, MD
Assistant Professor of Medicine
Johns Hopkins Medicine
Medical Research: What are the main findings of the study?
Dr. Trost: In our study, we reported the use of two relatively simple tactics to significantly reduce the number of unnecessary blood tests to assess symptoms of heart attack and chest pain and to achieve a large decrease in patient charges.
1) Provided information and education to physicians about proven testing guidelines and
2) Made changes to the computerized provider order entry system at the medical center, part of the Johns Hopkins Health System. The guidelines call for more limited use of blood tests for so-called cardiac biomarkers. A year after implementation, our intervention led to an estimated $1.25 million reduction in laboratory charges.

Medical Research: What are the main findings of the study?Dr. Pibarot: The optimal timing of aortic valve replacement (AVR) in asymptomatic patients with severe aortic stenosis (AS) remains a matter of debates. Both the American and European guidelines recommend AVR for patients with severe AS who present with symptoms or left ventricular (LV) systolic dysfunction. However, patients with aortic stenosis are often older, less physically active and have more comorbidities, which make the assessment of AS-related symptoms challenging and unreliable. In this study by Capoulade et al, plasma levels of brain natriuretic peptide (BNP) were obtained in 157 patients with severe asymptomatic aortic stenosis and preserved LV ejection fraction at peak of exercise-stress echocardiography. Patients in the upper (>95 pg/ml) and mid (>45 pg/ml) tertiles of exercise BNP respectively had a 5- and 3- fold increase in the risk of events (i.e. AVR or death) compared to those in the lower tertile. Similar results were obtained in the subset of patients with low resting BNP.

MedicalResearch: What are the main findings of the study?Answer: Although any medical test should be used to change management, the extent to which CCTA (Cardiac computed tomography angiography) findings are associated with medication changes (aspirin and lipid lowering) is not previously extensively studied.
Thus, we conducted the largest and one of the longest follow up studies of preventive cardiovascular medications before and after coronary computed tomography angiography (CCTA). We demonstrated that CCTA findings are associated with significant changes in preventive medications after CCTA.
MedicalResearch.com Interview with: David Strauss, M.D., Ph.D., Senior Author

U.S. Food and Drug Administration, Silver Spring, Md
MedicalResearch: What are the main findings of the study?Dr. Strauss:The underrepresentation of women in clinical trials for cardiac resynchronization therapy (CRT) devices, as with other devices, has made it difficult to assess differences in the safety and effectiveness of these devices for women vs. men. The FDA is exploring the potential of pooling and analyzing data from multiple trials to bridge the knowledge gap for certain subpopulations (such as women) often underrepresented in medical device clinical trials. By conducting one such meta-analysis, the FDA found that women benefit from cardiac resynchronization therapy (CRT) significantly more than men do.

Beijing , China
MedicalResearch: What are the main findings of the study?Professor Jiang: In this first representative nationwide assessment of quality of care in China, we studied 13,815 hospital admissions for STEMI in 162 hospitals across China over the past decade. We found that the incidence of hospital admission for STEMI quadrupled from 3.7 per 100,000 in 2001 to 15.8 per 100,000 in 2011.
There were substantial changes in testing and treatment patterns. Over the study period, the rate of testing for troponin increased from 21.4% in 2001 to 66.5% in 2011. Additionally, based at the ideal patients’ analysis, the use of several highly effective treatments for STEMI, including aspirin, clopidogrel and statins, improved over the study period. However, other therapies known to reduce mortality in STEMI patients – such as β-blockers and ACE inhibitors – were underused with only 57.7% of patients receiving beta-blockers and 66.1% ACE inhibitors respectively in 2011.
While the proportion of patients receiving reperfusion therapy remained constant, there was a notable shift away from fibrinolysis, which was the primary means of reperfusion in 2001, towards primary PCI. However, in 2011, only 27.6% of patients admitted to Chinese hospitals for STEMI received primary PCI, the gold standard of treatment, while 27.4% received fibrinolytic therapy in the ideal patients.
Despite increasing overall intensity of treatment, procedure use, and testing, no significant change in the rate of in-hospital death from STEMI was seen over the study period. (more…)

MedicalResearch: What are the main findings of the study?Dr. Shah:We discovered that in a group of patients who were undergoing heart evaluation with coronary angiography, symptoms of depression predicted increased risk of coronary artery disease and death in women aged 55 years or less. This relationship was stronger in these women than older women, as well as in men aged 55 years or less. Over 1 in 4 women aged 55 years or less had moderate to severe depression, which was higher than any other group; these women had over twice the risk of having heart disease or dying over the next 3 years compared to those with none or mild depression.

MedicalResearch: What are the main findings of the study?Dr. Huybrechts: In this cohort study including 949,504 pregnant women enrolled in Medicaid, we examined whether the use of selective serotonin reuptake inhibitors (SSRIs) and other antidepressants during the first trimester of pregnancy is associated with increased risks for congenital cardiac defects. In order to control for potential confounding by depression and associated factors, we restricted the cohort to women with a depression diagnosis and used propensity score adjustment to control for depression severity and other potential confounders. We found no substantial increased risk of cardiac malformations attributable to SSRIs. Relative risks for any cardiac defect were 1.25 (95%CI, 1.13-1.38) unadjusted, 1.12 (1.00-1.26) depression-restricted, and 1.06 (0.93-1.22) depression-restricted and fully-adjusted. We found no significant associations between the use of paroxetine and right ventricular outflow tract obstruction (1.07, 0.59-1.93), or the use of sertraline and ventricular septal defects (1.04, 0.76-1.41); two potential associations that had been of particular concern based on previous research findings.

MedicalResearch.com Interview withProf. Julia I. Newton:
Dean of Clinical Medicine & Professor of Ageing and Medicine
Clinical Academic Office
The Medical School
MedicalResearch: What are the main findings of the study?Prof. Newton: In this study we have explored for the first time the characteristics of patients with Postural tachycardia in the UK
Postural Tachycardia Syndrome patients are predominantly female, young, well educated and have significant and debilitating symptoms that impact significantly upon their quality of life.
Despite this, there is no consistent treatment, high levels of disability and associated comorbidity.
Although individuals presented with symptoms at the same age, those attending a specialist clinic received a diagnosis quicker.
Symptom burden for those with Postural tachycardia is high and comparable to that seen in Chronic Fatigue Syndrome.
Chronic Fatigue Syndrome is recognized by the WHO as a neurological disorder and by the Disability Discrimination Act 2005 as a disability. At the current time those with Postural Tachycardia Syndrome suffer to the same extent as those with Chronic Fatigue Syndrome but do not receive the same protection from the law.
It is important that more work is done to understand the underlying autonomic abnormality in those with Postural Tachycardia Syndrome in order to allow us to develop targeted treatments that are effective and go beyond the currently available simply symptomatic management.
MedicalResearch.com Interview with: Evan Thacker PhD
Brigham Young University
MedicalResearch: What are the main findings of the study?Dr. Thacker:In this study of over 17,000 American adults aged 45 and above, we first measured people’s cardiovascular health based on their smoking habits, diet, physical activity, body weight, blood pressure, blood cholesterol, and blood sugar. We then tracked these people for several years with cognitive function tests which measure memory and thinking abilities. The main finding of our study was that people who had the lowest levels of cardiovascular health at the beginning of the study were more likely to experience cognitive impairment – poor performance on the cognitive function tests – at the end of the study. People who had medium to high levels of cardiovascular health were less likely to experience cognitive impairment.

MedicalResearch.com Interview with: Laurie Lambert, PhD
Unité d'évaluation en cardiologie
Institut national d'excellence en santé
et en services sociaux (INESSS)
MedicalResearch: What are the main findings of the study?Dr. Lambert: Patients with ST-elevation myocardial infarction (STEMI) are frequently transferred for percutaneous coronary reperfusion from a hospital without this capability. Favourable outcomes depend on minimizing delays to treatment. A major component of delay is the time from the patient’s arrival at the first hospital’s emergency department to departure to the hospital where percutaneous reperfusion will be performed, the ‘door-in-door-out’ time or DIDO. We characterized this component of delay in a systematic field evaluation of STEMI treatment over a large and populous geographic area.
The major contributors to DIDO time were the delays
(1) from the initial in-hospital ECG acquisition to transfer activation by the emergency physician and
(2) from arrival of the transfer ambulance at the first hospital to departure of the ambulance for the primary percutaneous coronary intervention center. When the DIDO interval was timely (30 minutes or less as recommended by guidelines), reperfusion treatment was far more frequently within guideline-recommended delays (90 minutes or less). In fact, this benchmark of DIDO time was met in only 14% of cases. We identified a number of factors associated with untimely DIDO, an important one being an ambiguous presenting ECG. DIDO times were faster when patients arrived at the first hospital by ambulance particularly when retransfer to the second hospital was with the same ambulance that had remained on standby.

Nashville TN 37212
MedicalResearch: What are the main findings of the study?Dr. Roumie:This retrospective cohort study compared time to acute myocardial infarction (AMI), stroke, or death among Veterans with diabetes that were initially treated with metformin, and subsequently added either insulin or sulfonylurea. Among 178,341 Veterans on metformin monotherapy, 2,948 and 39,990 added insulin or sulfonylurea, respectively. Patients were about 60 years old, about 35% had history of heart disease or stroke, had been on metformin for an average of 14 months and their hemoglobin A1c was 8.1% at the time of addition of the second medication. Compared to those who added a sulfonylurea, those who added insulin to metformin had a 30% higher risk of the combined outcome of heart attack, stroke, and all-cause mortality. Although new heart attacks and strokes occurred at similar rates in both groups, mortality was higher in patients who added insulin.

Associate Professor of Medicine - Geriatrics
Director, School of Geriatrics

University of Florence and Azienda Ospedaliero-Universitaria Careggi
MedicalResearch: What are the main findings of the study?Professor Di Bari: This study is based on the AMI-Florence 2 registry, which recorded all acute coronary syndromes (ACS) occurring in one year in the metropolitan area of Florence, Italy. This area has one of the top prevalence figures in the country for application of percutaneous coronary intervention (PCI) to treat ACS, at least in cases with ST-segment elevation myocardial infarction (STEMI). Nevertheless, in our study the procedure turned out to be largely underused in older, complex patients, who mostly had NSTEMI: the greater the background risk (as expressed by the Silver Code, a simple, validated prognostic tool based of administrative data), the lower the chances for application of PCI, independent of possible contraindications to PCI, such as anaemia or renal insufficiency.
At the same time, the long-term survival advantage offered by PCI increased with increasing background risk: when comparing patients receiving and not receiving PCI across strata identified on the basis of the Silver Code, one-year survival was only marginally greater in patients treated with PCI when their Silver Code score suggested low background risk, whereas the mortality gradient increased progressively along with Silver Code score, to reach its maximum in patients with the greatest values of Silver Code score. Within the limits of an observational study, cardiac and non-cardiac comorbidities, contraindications to PCI, clinical characteristics of the ACS and hospital of admission could not justify these findings.

Assistant Professor of Medicine
Interventional Cardiac and Endovascular Laboratory
Greenberg Division of Cardiology, Department of Medicine
Weill Cornell Medical College/The New York Presbyterian Hospital
MedicalResearch: What are the main findings of this study?Dr. Kim:The main findings of the study include:
From 2007-2011, there was no significant change in the rate of acute MI in both male and female cohorts in U.S. . Although there was a decline in the rate of ST-elevation (STEMI) in those ≥55 years old, the rate remains steady in patients < 55 years old, especially in the female cohort after 2009.
Female patients <55 years old with MI were sicker at baseline than the male counterparts with more likelihood of having diabetes, hypertension, chronic renal insufficiency, peripheral vascular disease, congestive heart failure and obesity.
Female patients were more likely to present with non– STEMI vs. STEMI and more likely to develop shock complicating their MIs.
Female patients are less likely to undergo coronary artery revascularization including percutaneous coronary intervention and coronary artery bypass surgery.
Unadjusted risk of death was higher in female vs male (5.2% vs. 3.7%, p<0.001) along with higher incidence of stroke (0.5% vs. 0.3%, p<0.001), bleeding (4.9% vs. 3.0%, p<0.001), vascular complication (0.6% vs. 0.4%, p<0.001) and ARF (11.6% vs. 9.6%, p<0.001). After adjustment, death (OR 1.10 CI 1.04-1.17), stroke (OR 1.31 CI 1.10-1.55), bleeding (OR 1.30 CI 1.22-1.37), and vascular complications (OR 1.33 CI 1.15-1.55) were all significantly higher for female cohort.

MedicalResearch.com Interview with: Eleni Rapsomaniki, PhD
The Farr Institute of Health Informatics Research
Department of Epidemiology & Public Health
University College London London
MedicalResearch: What are the main findings of the study?
Dr. Rapsomaniki: Our data shows that hypertension is associated with considerable reduction in CVD-free life expectancy. Based on our estimates a 30-year old with hypertension suffered from CVD 5 years earlier compared to a similarly aged individual with normal blood pressure.
We noted substantial heterogeneity in the associations of blood pressure with specific cardiovascular outcomes. For example a 20 mmHg increase in systolic blood pressure was associated with ~40% higher risk of stable angina, and intracerebral or subarachnoid haemorrhage but less than 10% increase in risk of abdominal aortic aneurysm.
In all age groups from 30 to over 80 people with a systolic blood pressure 90–114 mm Hg and a diastolic blood pressure of 60–74 mm Hg had the lowest risk of all cardiovascular diseases, and we found no J-shape associations.

Associate Professor of Medicine (Geriatrics), Baylor College Medicine
Medicalresearch: What are the main findings of the study?Dr. Tan:Our findings¹ are similar to that of an early study by Shores et al ² and other studies on endogenous testosterone that found testosterone lowered mortality. In the analysis of 39,937 patients at the Low T Centers up to 5 years, the rate ratios of new MI and strokes on testosterone as compared to general community based data sets (3,4) was 0.12 (C.I. 0.08-0.18, p<0.0001) and 0.05 (C.I 0.02-0.13, p<0.0001) respectively. Thus, there appears to be a lower risk of heart attacks and strokes with patients on testosterone. While the compared population sets are not identical or real controls; our study does suggest that rates of MI and strokes in real life practice with testosterone treated patients are even lower than the general population registries (which may include older patients).
