Association Of Lipid-Related Genetic Variants With The Incidence Of Atrial Fibrillation: The Afgen Consortium, 2016 University of Minnesota, Minneapolis
Association Of Lipid-Related Genetic Variants With The Incidence Of Atrial Fibrillation: The Afgen Consortium, Faye L. Norby, David D. Mcmanus
David D. McManus
BACKGROUND: Several studies have shown associations between blood lipid levels and the risk of atrial fibrillation (AF). To test the potential effect of blood lipids with AF risk, we assessed whether previously developed lipid gene scores, used as instrumental variables, are associated with the incidence of AF in 7 large cohorts.
METHODS: We analyzed 64,901 individuals of European ancestry without previous AF at baseline and with lipid gene scores. Lipid-specific gene scores, based on loci significantly associated with lipid levels, were calculated. Additionally, non-pleiotropic gene scores for high-density lipoprotein cholesterol (HDLc) and low-density lipoprotein cholesterol (LDLc) were calculated using ...

BACKGROUND: The epidemiology of atrial fibrillation (AF) without comorbidities, known as 'lone AF', is uncertain. Although it has been considered a benign condition, we hypothesized that it confers a worse prognosis compared with a matched sample without AF.
METHODS: We described the proportion of AF without comorbidities (clinical, subclinical cardiovascular disease and triggers) among the entire AF sample in Framingham Heart Study (FHS). We compared AF without comorbidities with typical AF, and age-, sex- and cohort-matched individuals without AF, using Cox proportional hazards analysis in relation to combined cardiovascular events (stroke, heart failure, myocardial infarction), and mortality.
RESULTS: Of 10 ...
The Effect Of A Square-Stepping Exercise Intervention On Heart Rate Variability In Older Individuals With Type 2 Diabetes And Subjective Cognitive Complaints, 2016 The University of Western Ontario
The Effect Of A Square-Stepping Exercise Intervention On Heart Rate Variability In Older Individuals With Type 2 Diabetes And Subjective Cognitive Complaints, Claire E. Riley
Electronic Thesis and Dissertation Repository
Aging is associated with increased onset of diseases such as type 2 diabetes (T2D) and cognitive impairment. Heart rate variability (HRV), a measure of autonomic function, is reduced in T2D and may have the potential to indicate cognitive decline in this population. Square-stepping exercise (SSE) is a novel cognitive exercise recently implemented in cognitive research, which may have the potential to improve global cognitive function in T2D individuals. Participants with T2D (N=25, aged ≥ 50y) and self-reported cognitive complaints were randomized into either an SSE intervention or a wait-list (WL) control group for 24-weeks. HRV parameters (time and frequency domain ...
Acute Appendicitis: A Potential Complication Of Continuous-Flow Left Ventricular Assist Device Support, 2016 University of North Carolina
Acute Appendicitis: A Potential Complication Of Continuous-Flow Left Ventricular Assist Device Support, Joshua S. Roark, Akinniran A. Abisogun, Jason N. Katz
The VAD Journal
Acute appendicitis, while common in younger patients, is an unusual cause for hospitalization among older adults. We report a case series of 3 individuals who had been previously implanted with a continuous-flow left ventricular assist device (CF-LVAD) for end-stage heart failure, and who subsequently developed acute appendicitis. Both axial-flow technology and nonpulsatile systemic blood flow have been implicated as potential causes for bleeding and thrombosis in contemporary LVAD populations(1-3). This case series represents the first report of acute appendicitis as an adverse event following LVAD implantation and represents a patient demographic that would historically be at very low-risk for ...
Suppression Of Ischemia In Arterial Occlusive Disease By Jnk-Promoted Native Collateral Artery Development, 2016 University of Massachusetts Medical School
Suppression Of Ischemia In Arterial Occlusive Disease By Jnk-Promoted Native Collateral Artery Development, Kasmir Ramo, Koichi Sugamura, Siobhan M. Craige, John F. Keaney Jr., Roger J. Davis
Arterial occlusive diseases are major causes of morbidity and mortality. Blood flow to the affected tissue must be restored quickly if viability and function are to be preserved. We report that disruption of the mixed-lineage protein kinase (MLK) - cJun NH2-terminal kinase (JNK) signaling pathway in endothelial cells causes severe blockade of blood flow and failure to recover in the murine femoral artery ligation model of hindlimb ischemia. We show that the MLK-JNK pathway is required for the formation of native collateral arteries that can restore circulation following arterial occlusion. Disruption of the MLK-JNK pathway causes decreased Dll4/Notch signaling, excessive ...
Pathway By Which Vagus Nerve Stimulation Of B Fibers Affects Heart Rate, 2016 Purdue University
Pathway By Which Vagus Nerve Stimulation Of B Fibers Affects Heart Rate, Kelsey Wasilczuk, Matthew Ward, Pedro Irazoqui
The Summer Undergraduate Research Fellowship (SURF) Symposium
Heart failure (HF) affects over 5 million adults in the United States. Many HF patients have a high resting heart rate, which is correlated with a high mortality rate. In recent years, vagus nerve stimulation (VNS) has become an increasingly researched therapy to reduce the resting heart rate of HF patients. However, current dosage given during VNS is increased incrementally at the doctor’s office until side effects present themselves in a patient. In addition, the means by which the therapy works is not completely understood. To better understand the therapy’s mechanisms, the right cervical vagus nerve of several ...

Age And Sex Differences In Long-Term Outcomes Following Implantable Cardioverter-Defibrillator Placement In Contemporary Clinical Practice: Findings From The Cardiovascular Research Network, Frederick A. Masoudi, Jerry H. Gurwitz, Robert J. Goldberg
Robert J. Goldberg
BACKGROUND: Patient sex and age may influence rates of death after receiving an implantable cardioverter-defibrillator for primary prevention. Differences in outcomes other than mortality and whether these differences vary by heart failure symptoms, etiology, and left ventricular ejection fraction are not well characterized.
METHODS AND RESULTS: We studied 2954 patients with left ventricular ejection fraction < /=0.35 undergoing first-time implantable cardioverter-defibrillator for primary prevention within the Cardiovascular Research Network; 769 patients (26%) were women, and 2827 (62%) were aged > 65 years. In a median follow-up of 2.4 years, outcome rates per 1000 patient-years were 109 for death, 438 for hospitalization, and 111 for heart failure hospitalizations. Procedure-related complications occurred in 8.36%. In multivariable models, women had significantly lower risks of death (hazard ...

Allison, Hoa L. Nguyen, Duc A. Ha, German A. Pihan, Ha N. Ly, Hanh T. Tran, Ngoc T. Phan, Nguyen C. Vu, Minjin Kim, Robert J. Goldberg
Jeroan J. Allison
BACKGROUND: Vietnam is experiencing an epidemiologic transition with an increased prevalence of non-communicable diseases. At present, the major risk factors for cardiovascular disease (CVD) are either on the rise or at alarming levels in Vietnam; inasmuch, the burden of CVD will continue to increase in this country unless effective prevention and control measures are put in place. A national survey in 2008 found that the prevalence of hypertension (HTN) was approximately 25 % among Vietnamese adults and it increased with advancing age. Therefore, novel, large-scale, and sustainable interventions for public health education to promote engagement in the process of detecting and ...

Efforts to reverse the pathologic consequences of vulnerable plaques are often stymied by the complex treatment resistant pro-inflammatory environment within the plaque. This suggests that pro-atherogenic stimuli, such as LDL cholesterol and high fat diets may impart longer lived signals on (innate) immune cells that persist even after reversing the pro-atherogenic stimuli. Recently, a series of studies challenged the traditional immunological paradigm that innate immune cells cannot display memory characteristics. Epigenetic reprogramming in these myeloid cell subsets, after exposure to certain stimuli, has been shown to alter the expression of genes upon re-exposure. This phenomenon has been termed trained innate ...

Air Pollution, Pulmonary Oxidative Stress, And The Endothelin System In The Development Of Cardiovascular Injury., Jordan B. Finch
Electronic Theses and Dissertations
The goal of this project was to examine the role of endothelin-1 (ET-1) as a mediator in the pathway between air pollution exposure and the development of vascular injury. A human cohort and male mice (C57BL/6 and ecSOD-Tg) were used to evaluate changes in the ET-1 system in response to exposures of fine particulate matter (PM2.5). Human ET-1 levels were significantly associated with environmental factors and markers of vascular change, but were decreased with increased PM2.5. No association was seen between ET-1 and endothelial progenitor cells (EPCs) except for EPC-4, possibly indicating a regulatory relationship with this ...

Ultrasound-Guided Intralesional Bleomycin Injection (Ibi) For Treatment Of Cutaneous Hemangiomas And Vascular Malformations, Yousuf Memon, Nuzhat I. Malik, Naveed Anjum, S. Kamran Ahmed, Sadaf Saeed
The Journal of Global Radiology
Purpose: To report the therapeutic outcome of ultrasound-guided intralesional injection of bleomycin in the treatment of cutaneous hemangiomas and vascular malformations.
Material & Methods: The medical records of patients with cutaneous hemangiomas and vascular malformations treated with the intralesional injection of bleomycin under ultrasound guidance between August 2009 and June 2013 at the Indus Hospital, Karachi were reviewed retrospectively using a computerized medical record information management system. Data were extracted using a pre-coded performa that included patient demographics, type and location of lesion, number of treatments, presenting/pre- and post-treatment clinical symptoms (pain, swelling, heaviness, size, discoloration), ultrasound appearance and vascularity, and post-treatment side effects. The dose range of bleomycin was 0.5-1.0 mg/kg, but not exceeding 15 mg in a single session. A maximum of four treatments were given in any given patient except for one, who presented with recurrence after a year of complete resolution. Therapeutic outcome was determined using review of ultrasound images and recorded clinical assessment. Treatment response was categorized as: (i) complete resolution [more than 90% reduction]; (ii) substantial reduction [more than 50% reduction]; (iii) mild reduction [25% reduction]; or, (iv) no improvement [ < 10% reduction].
Results: A total of 30 patients (16 female, 14 male), ranging in age from 8 months to 48 years (mean age 10.2 years), were treated from 2009 to 2013. There were 23 hemangiomas. Seven were vascular malformations, of which five were lymphatic malformations and two were venous malformations. Twenty-eight lesions were located in the head and neck region, and two were ...

Open Access Articles
BACKGROUND: Cross-sectional analyses suggest that total and low-density lipoprotein cholesterol (LDL-c) trends that had been declining are now reversing. We examined longitudinal data from the Coronary Artery Risk Development in Young Adults (CARDIA) study to examine secular trends in total cholesterol, LDL-c, high-density lipoprotein cholesterol (HDL-c), and triglycerides over 25 years. We also assessed whether modifiable lifestyle factors (body mass index, physical activity, alcohol consumption, smoking, and lipid-lowering medications) are associated with these trends.
METHODS AND RESULTS: CARDIA recruited 5115 black and white men and women ages 18 to 30 years from 4 US communities in 1985-1986, and re-examined them ...
