Medical Research: What are the main findings of the study?Dr. Bangalore: We found that while CABG was associated with mortality benefit when compared with bare metal stents or first generation drug eluting stent, the gap between CABG and PCI was smaller and non significant when PCI was with newer generation DES. The same was true for repeat revascularization with the magnitude of benefit with CABG descending considerable from comparison with balloon angioplasty to newer generation DES.

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: 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.

Newcastle University
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

Provo, Utah
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.

Unité d'évaluation en cardiologie

Montréal, Québec
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.

Florence Italy
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

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.

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).

MedicalResearch: What are the main findings of the study?Dr. Labos:A higher genetic risk score (GRS) composed of a set of recently discovered genetic markers strongly linked to cardiovascular disease is associated with an earlier age of first acute coronary syndromes (ACS). We also found that other traditional risk factors such as smoking, obesity and male sex were also associated with an earlier ACS. Two medication classes were also associated with age of first ACS: hormone replacement therapy was associated with earlier ACS while aspirin was associated with ACS occuring at a later age.

MedicalResearch: What are the main findings of the study?Dr. Demant:Our study shows that increasing severity of heart failure is associated with an increased risk of developing diabetes. Increasing loop-diuretic dosage was used as a proxy for heart failure severity. Patients with the most severe heart failure were three times more likely to develop diabetes than those with the least severe. Patients who were also being treated with ACE inhibitors (angiotensin-converting-enzyme inhibitors) had a less pronounced increase in diabetes risk.
Patients who developed diabetes were 16% more likely to die than those who did not develop diabetes.

MedicalResearch: What are the main findings of the study?Answer: We analyzed data from almost 4 million hospitalizations for atrial fibrillation (AF) from more than 1,200 hospitals across 45 states in last decade, and found that
- Hospitalization rates for atrial fibrillation have increased exponentially among US adults during the past 10 years, particularly in those 65 years or older.
- The most frequent coexisting conditions were hypertension (59.99%), diabetes (21.47%) and chronic pulmonary disease (20.01%).
- In terms of geographic distribution of admissions, the hospitals in the South constitute (38.5%) the highest percentage of atrial fibrillation hospitalizations, followed by Midwest (24.9%), Northeast (22.2%) and West (14.4%).
- Overall in-hospital mortality was 1%. The mortality rate was highest in >80 years age group (1.93%) and patients with concomitant heart failure (8.2%).
- The percentage of patients discharged to nursing facility increased from 8.1% in 2000 to 11.5% in 2010 and need for home health care increased from 6.7% to 13.1%. Approximately one fourth of the patients (25.83%) were discharged to long-term care institution if atrial fibrillation hospitalization was complicated by acute ischemic stroke.
- Mean cost of AF hospitalization increased significantly from $6,410 in 2001 to $8,439 in 2010 (24.04% increase, p <0.001) even after adjusting for inflation. This represents an absolute increment in annual national cost from approximate 2.15 billion dollars in 2001 to 3.46 billion dollars in 2010. The mean cost of care was highest if AF hospitalization was associated with heart failure ($33,161) and valvular disorders ($28,030).

University of Colorado, Division of Cardiology
Section of Advanced Heart Failure and Transplantation
MedicalResearch: What are the main findings of the study?Answer: We interviewed 22 patients who were offered destination therapy left ventricular assist devices (DT LVAD), 15 with DT LVADs and 7 who declined. We found a strong dichotomy between decision processes with some patients (11 accepters) being automatic and others (3 accepters, 7 decliners) being reflective in their approach to decision making. The automatic group was characterized by a fear of dying and an overriding desire to live as long as possible: [LVAD] was the only option I had…that or push up daisies…so I automatically took this. In contrast, the reflective group went through a reasoned process of weighing risks, benefits, and burdens: There are worse things than death. Irrespective of approach, most patients experienced the DT LVAD decision as a highly emotional process and many sought support from their families or spiritually.
