Filter by:This study will examine the context of making high quality dietary choices among Black adults with hypertension. Secondly, this study will also investigate what Black adults need or desire to participate in a digital intervention to improve dietary quality by adopting the DASH eating pattern.
Bicuspid aortic valve (BAV) is the most common congenital heart anomaly in the general population (1-2% of all individuals). In affected people, the aortic valve (the structure ensuring one way blood flow between the heart's left pumping chamber, the left ventricle and the main body artery, the aorta) consists of 2 rather than 3 leaflets. This arrangement can cause the affected valve to have restricted opening or cause it to leak. Both situations put strain on the heart and patients with BAV across the age range may require surgery to replace the affected valve. BAV is therefore a condition associated with significant ill health and early mortality. BAV is known to cluster in families and is likely to have a genetic cause. We don't fully understand the inheritance of BAV or the specific genes involved in its development. Learning more about this is the basis of the BRAVE study. We will ask patients with BAV and their relatives (who may or may not have BAV) to take part in the study. Blood samples obtained from the participants will be used for analyses of their genetic composition. This information, linked with the clinical data concerning who does and does not have BAV, will potentially enable the identification of the gene changes responsible for the disease. This, we hope, will give us a much better understanding of the mechanisms leading to this serious and common condition.
Sudden cardiac death (SCD) is the number one cause of on-duty firefighter death. It is most likely to occur in adults who are not physically fit that engage in sudden vigorous exercise. Cardiorespiratory physical fitness (also known as aerobic fitness) is a major heart disease risk factor. In FIT and FIRED UP, the study investigators looked at the influence of cardiorespiratory fitness on blood pressure, heart rate, and other heart markers taken from the blood before and after a vigorous exercise test to maximal effort among firefighters from a local fire department in Connecticut. In addition, the investigators also looked at how lifestyle habits including physical activity, nutrition, stress, and sleep may influence our findings. It was hypothesized that aerobically fit firefighters would show less stress on their heart than unfit firefighters.
The goal of this study is to verify whether electrical stimulation of the cervical spinal cord can activate muscles of the arm and hand in people with hemiplegia following stroke. Participants will undergo a surgical procedure to implant a system which provides epidural electrical stimulation (EES) of the cervical spinal cord. Researchers will quantify the ability of EES to recruit arm and hand muscles and produce distinct kinematic movements. The implant will be removed after less than 30 days. Results of this study will provide the foundation for future studies evaluating the efficacy of a minimally-invasive neuro-technology that can be used in clinical neurorehabilitation programs to restore upper limb motor function in people with subcortical strokes, thereby increasing independence and quality of life.
to assess the oral mucosal alterations and their prevalence secondary to use cardiovascular drugs in a sample of Egyptian population with cardiovascular diseases .
Coronavirus disease (COVID-19) related pneumonia significantly impact patients with underlying cardiovascular (CV) conditions. Animal studies suggest that drugs commonly used to treated CV diseases may increase the ability of COVID-19 to infect cells. The RAAS-COVID-19 trial aims to assess whether temporarily holding these CV drugs in patients who are admitted with COVID-19, versus continuing them, in patients admitted with COVID-19 can impact short term outcomes.
The design included 152 patients with confirmed heart failure (HF) evaluated in two different periods of time: a baseline before the outbreak, and other during the outbreak of which 76 patients were randomized in each group. A care and follow-up guide was used as an instrument through a face-to-face survey (baseline group) and telemedicine (group outbreak). The primary outcome was the comparison of functional class modification observed in patients
Preeclampsia is a multi-system vascular disease which affects 2-5% of pregnancies. It is also a risk factor for the development of cardiovascular disease later in life and a number of functional and structural cardiac changes have been found in this population of patients. In mouse models disruption of a group of immune cells, neutrophils, has led to alteration of the placenta and offspring consistent with those seen in preeclampsia. These mice also have an abnormal cardiac function and structure (Nadkarni et al 2016). The investigators hypothesis that this may also occur in humans. This study aims to intimately link the maternal immunological and vascular components of cardiac dysfunction in women preeclampsia. The investigators hypothesise that in preeclampsia activated neutrophils may affect maternal immune system thus leading to myocardial injury and altered cardiac function. The study intends to identify the mechanisms by which the maternal immune system (focusing on neutrophil and T-cell subsets) affects cardiac function in women with preeclampsia. Specific aims to be addressed are: Aim 1: To correlate specific neutrophil phenotype(s) and function to cardiac function in women with preeclampsia during pregnancy Aim 2: To test whether specific activated neutrophil phenotype persists postpartum and whether this neutrophil phenotype correlates with cardiac function in women with preeclampsia postpartum The study population will comprise of 3 groups: 1. Normotensive pregnant (~33 patients) 2. Pregnancy-induced hypertension (PIH; New-onset hypertension after 20 weeks without proteinuria; ~33 patients) 3. Preeclampsia (~34 patients) Cardiac function will be evaluated using cardiovascular magnetic resonance, echocardiography and cardiac markers in the blood. The participants immune system will be assessed from blood samples looking at the immune cells, hormone levels and inflammatory and non-inflammatory mediators. The secondary research objective is to investigate whether changes in the immune system and cardiac function in participants is persistent after delivery. Therefore participants will have scans and blood tests both antenatally and at 3 months postnatally. By identifying key changes in immune cell type and function with cardiac abnormalities in women with preeclampsia, data obtained from this study could provide novel insight into how the maternal immune system influences cardiac changes in normal and preeclamptic pregnancies. Identifying such links could pave the way for future therapeutic targets.
This cohort study will obtain electronic health record (EHR) data (limited data set) from 21 health systems affiliated with the Cancer Center Cessation Initiative (C3I) network or health systems with large numbers of COVID-19 patients to explore whether smoking status, cancer history, and other risk factors among patients diagnosed with COVID-19 are associated with mortality and/or COVID-19 disease severity/complications. Each site will provide data from their health system EHR on a regular basis that includes all patients identified as having COVID-19 at some point in the interval from February 1, 2020, through January 31, 2022.
MITIGATE is a prospective, open-label, parallel-group, randomized, pragmatic clinical trial. The MITIGATE Study has been designed to evaluate the real-world clinical effectiveness of pre-treatment with icosapent ethyl (IPE), also known as Vascepa®, compared to usual standard of care to prevent and reduce the sequelae of laboratory-confirmed viral upper respiratory infection (URI)-related (i.e., COVID-19, influenza, and other known viral respiratory pathogens) morbidity and mortality in a high-risk cohort of adults with established atherosclerotic cardiovascular disease (ASCVD).
