Filter by:The Investigators will create a clinical database and a Biobank of stem cells derived from the blood of participants with cardiovascular disease. The Investigators will recruit participants from diverse racial and ethnic backgrounds with equal representation from both sexes. The Investigators expect to create stem cells and analyze the blood for protein biomarkers and genetic causes of cardiovascular disease. The stem cell biobank and clinical data will be a powerful tool for studying cardiovascular disease.
The goal of this observational study is to learn about the frequency of ATTR amyloid, cardiac involvement and associated features, in 150 patients aged 50 or more years, and operated for an idiopathic carpal tunnel syndrome, lumbar spine stenosis or total hip or knee arthroplasty for primary osteoarthritis. The main questions to be answered are: 1. What is the frequency of ATTR deposits in samples retrieved during surgery? 2. What is the frequency of cardiac involvement in ATTR positive patients? 3. What are the preoperative predictors of ATTR deposits? Participants will - have operative samples stained by Congo red in search of amyloid, which will be typed by immunochemistry in positive samples, - undergo a multimodal imaging search for cardiac involvement, if ATTR is identified, - undergo a preoperative complete clinical examination, including collection of medical history, ECG, biochemical tests, and imaging (ultrasound scans of rotator cuff and hip capsule in all participating patients, of the carpal tunnel in patients operated at this site, and MRI + standing profile radiography of the lumbar spine, in patients operated for lumbar stenosis) - ATTR positive patients will be proposed to be followed-up by a reference center, with the aim of an early diagnosis of cardiac involvement, allowing efficient mamagement. Researchers will assess the frequency of ATTR deposits at each operated site, the frequency or ATTR cardiopathy in ATTR + patients, and will compare demographic, clinical, biochemical, and imaging features in patients with and without ATTR deposits, to guide the indications of pathological examination during these frequent orthopedic surgeries
The purpose of this study is to test a culturally tailored, smartphone-delivered intervention designed to increase physical activity and reduce risk for heart disease and type 2 diabetes among African American women.
Heart failure (HF) is a global, public health issue that affects more than 63 million people worldwide; this burden is expected to increase substantially as the population ages. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality; there is also an immense impact on patients' health-related quality of life (HRQoL). Dapagliflozin was recently granted approval for heart failure by the European Commission, regardless of ejection fraction and whether the patient has diabetes. Real-world observational data are necessary to describe dapagliflozin use in real-world settings in order to assess treatment patterns, HF symptoms and their impact on physical limitation, HRQoL and work productivity, as well as health care utilization of patients treated with dapagliflozin in this setting under local treatment standard conditions in Germany.
Sudden cardiac death (SCD) is the final result of cardiac arrest (CA) , defined as an abrupt and unexpected loss of cardiovascular function resulting in circulatory collapse and death. Up to 50% of cardiac deaths in Europe are due to CA. The estimated mortality of CA is approximately 90%, and significant functional and/or cognitive disabilities often persist among those who survive. The advent of the implantable cardioverter-defibrillator (ICD) has revolutionized the prevention of SCD in high-risk patients with reduced left ventricular ejection fraction (LVEF<35%). However, the algorithm recommended by current guidelines based on LVEF, considered the only parameter to identify high-risk patients, cannot stratify the population and the spectrum of risk with high accuracy. Although the risk of CA is higher among patients with LVEF<35% and NYHA class>1, because of the enormity of the population size at risk (i.e., with organic heart disease and LVEF>35%), most SCD does occur in patients with LVEF>35%. Additionally, the majority of pts who receive the ICD for primary prevention of SCD will not benefit from the device (in the Sudden Cardiac Death in Heart Failure Trial published in 2005, the rate of appropriate ICD therapy was 21% at five years), and/or will experience some side effects of it. In the Israeli registry of patients who underwent ICD (n= 1729) or cardiac resynchronization therapy (n= 1326), the 12-year cumulative incidence of adverse events was 20% for inappropriate shock, 6% for device-related infection, and 17% for lead failure. Moreover, recent improvements in drug treatment for HF and myocardial revascularization have further reduced the incidence of SCD in pts with low LVEF. Finally, pts with advanced HF are unlikely to benefit from ICD therapy because of the high rates of non-arrhythmic deaths. Therefore, improved risk stratification approaches to guide the selection of pts for ICD implantation are needed, and only a multiparametric approach may aim to personalize the risk prediction of SCD across the broad spectrum of the phenotypes of HF patients. The RESPECT project has been designed to personalize the risk of SCD by integrating and interpreting information highly multidisciplinary: clinical and bio-humoral, genetics and electrocardiography, conventional and advanced cardiac imaging, and data science. The investigators hypothesized that machine learning models capable of dealing with non-linearities and complex interactions among predictors, including genetic, clinical, electrocardiographic, bio-humoral, echocardiographic, cardiac magnetic resonance (CMR), and nuclear cardiology data, would have superior accuracy in predicting the occurrence of SCD compared with the currently recommended metrics of NYHA class and LVEF by two-dimensional echocardiography and that the personalized risk prediction of SCD will translate in more cost-effective use of ICDs. In addition, the investigators will use the multiparametric predictive models to develop a cloud-computing app that will allow clinicians to predict the risk of occurrence of SCD based on specific covariate profiles of individual patients.
To investigate clinical and survival outcomes following transcatheter tricuspid valve repair or replacement.
To study the association between DISC1 RNA expression levels and cardiac function in patients with schizophrenia.
Currently, research on the effect of thiamine administration during transcatheter closure on the structure and function of the left ventricle by examining levels of matrix metalloproteinase-9 and tissue inhibitor of metalloproteinase-1 in children with left to right shunt congenital heart disease has never been carried out in Indonesia, so it is necessary carried out this research. This research was carried out by administering 100 mg of thiamine once per day to patients post transcatheter closure for 28 days. The parameters assessed were MMP-9, TIMP-1, and echocardiography to assess the structure and function of the left ventricle in CHD patients with left to right shunt lesions.
MANCAVA sets out fundamental methodologies for characterizing human fundamental physiological system interactions at a whole-body level, particularly focusing on the interplay among cortical brain activity, autonomic function, and cerebrovascular autoregulatory mechanisms. By investigating the complex, time-varying mechanisms underlying the multisystem dynamic interactions, novel methods linking various brain areas and reflex functions to target organs and districts such as heart and circulatory system are proposed with the clinical aim linked to the emerging topic of depression. In this scenario, proper new mathematical tools will allow a significant leap from the current state of the art, paving the way towards a new understanding of leading comorbid contributors to global diseases such as cardiac and cerebrovascular morbidity in mood disorders. In turn, this will provide an integration among physiological and psychological dimensions for a more holistic view on depression. Researchers, professionals, and patients will all benefit from a comprehensive assessment of brain-mind-body interplay, leading to the new extended definition of default mode/mood network, neurovascular-evoked responses to autonomic stimuli, brain-autonomic consequences of emotional responses, and physiological substrates of depressive states.
In cardiac surgeries performed with median sternotomy, mediastinal and thoracic tube placement sites are outside the area of effect of parasternal blocks, and sometimes the sternotomy incision extends below the T6 dermatome. Recto intercostal fascial plane block (RIFPB) has been defined as a complementary block for analgesia of this region. This study aims to evaluate the effectiveness of the combination of ultrasound-guided recto-intercostal fascial plane block and pectointercostal fascial block for postoperative analgesia management after open heart surgery (coronary artery bypass) with median sternotomy.
