Filter by:Arterial calcification is very common in the incident hemodialysis population, ranging 71-83%.Given that cardiovascular disease is a major cause of mortality in the hemodialysis population, medial arterial calcification may contribute through increased risk of sudden death and congestive heart failure. Applanation tonometry is the method of choice to measure pulse wave velocity and pulse wave analysis. The primary objective will be to assess the effect of a 16 week exercise program on aortic pulse wave velocity as the vascular parameter and gait speed as the physical functioning parameter. The secondary objectives will assess the effect of the exercise program on ultrafiltration rates, weight, SBP, DBP, BNP, hsTroponin, serum calcium, phosphate, albumin, glucose, LDL, HDL, TG, glycated hemoglobin, hemoglobin, CRP, micro RNAs (21, 126, 133, 146a, 221/222 and 210) and hospitalizations.
The goal of this study was to identify the etiology of events and demographics of patients that experience complications requiring activation of the Rapid Response Team (RRT) during the first 24 h following anesthetic care.
The Silesian Cardiovascular Database is an observational study of all patients hospitalized due to cardiovascular diseases. The date include information on the clinical characteristics, treatment modalities and prognosis in this population. The data include information on all the applicable diagnostic and therapeutic procedures, prognosis and hospitalization costs. Likewise, data have been collected specialist care outpatient visits and primary health care patients were hospitalized.
The aim of Patient-Centred Innovations for Persons With Multimorbidity (PACE in MM) study is to reorient the health care system from a single disease focus to a multimorbidity focus; centre on not only disease but also the patient in context; and realign the health care system from separate silos to coordinated collaborations in care. PACE in MM will propose multifaceted innovations in Chronic Disease Prevention and Management (CDPM) that will be grounded in current realities (i.e. Chronic Care Models including Self-Management Programs), that are linked to Primary Care (PC) reform efforts. The study will build on this firm foundation, will design and test promising innovations and will achieve transformation by creating structures to sustain relationships among researchers, decision-makers, practitioners, and patients. The Team will conduct inter-jurisdictional comparisons and is mainly a Quebec (QC) - Ontario (ON) collaboration with participation from 4 other provinces: British Columbia (BC); Manitoba (MB); Nova Scotia (NS); and New Brunswick (NB). The Team's objectives are: 1) to identify factors responsible for success or failure of current CDPM programs linked to the PC reform, by conducting a realist synthesis of their quantitative and qualitative evaluations; 2) to transform consenting CDPM programs identified in Objective 1, by aligning them to promising interventions on patient-centred care for multimorbidity patients, and to test these new innovations' in at least two jurisdictions and compare among jurisdictions; and 3) to foster the scaling-up of innovations informed by Objective 1 and tested/proven in Objective 2, and to conduct research on different approaches to scaling-up. This registration for Clinical Trials only pertains to Objective 2 of the study.
Heart surgery procedures are still widely used worldwide for the treatment of patients with heart problems, and rates of complications in the postoperative period related to them remain high. In these patients, physical conditioning programs result in improved functional capacity, and reducing the heart rate and systolic blood pressure. The inspiratory muscle training is also emerging as a valuable strategy in the treatment of cardiac patients. The study of the interaction between cardiac rehabilitation and high intensity IMT about these changes is not yet understood in this population. The aim of this study is to assess the effects of inspiratory muscle training high intensity associated with cardiac rehabilitation exercise performance of patients in the postoperative period of CABG surgery.
Background: Coronary artery disease causes plaque in arteries. This can cause stroke or heart disease. Drugs called statins might shrink plaque. Researchers want to study how CT scanning can determine if an individuals arterial plaque has decreased while taking statins. Objectives: To measure the change in coronary artery plaque volume in people treated with high-intensity statin therapy using CT and MRI scans. To study the metabolic activity of plaque in arteries. To determine how well plaque measurements from heart CT scans can be replicated. Eligibility: Men ages 40-75 and women ages 40-75 who are good candidates for statin treatment Design: Visit 1: participants will be screened with: - Medical history - Blood tests - Heart MRI and CT scan: An IV inserted into an arm or hand vein removes blood and injects contrast, and medicine if needed. Participants lie on a table that slides into a machine that takes pictures of the body. For the CT scan, if their heart rate is too high, they get medicine to lower it. They breathe in a special way, holding their breath for 5 seconds. Participants will begin high-intensity statin treatment. Participants will have 7 more visits over 3 years. All visits include blood tests and medication review. Some may also include: - Statin treatment adjustment - CT scan - MRI scan - Physical exam Participants may join the PET Substudy. This includes 5 more visits during the study. These include: - Getting an IV in an arm vein - Blood tests - PET scans: They fast 12 hours before. Participants may join the Reproducibility Substudy if they had a slow heart rate during their first CT scan. This includes 1 additional heart CT scan 4 weeks later.
HIV-infected individuals treated with antiretroviral medications are living longer, but have an increased risk of heart disease when compared to non-HIV-infected individuals. A hormone called aldosterone, which regulates blood pressure and sodium balance, is elevated in the HIV population in association with with increased belly fat and altered glucose metabolism. Elevations in aldosterone hormone may also be associated with abnormal blood flow, inflammation, and coronary plaque in the heart. This study is being conducted to evaluate whether therapies to reduce the actions of aldosterone may decrease the burden and progression of heart disease in the HIV population.
Hypertension is a leading risk factor for cardiovascular disease (CVD) globally, accounting for 25-35% of the population-attributable fraction. Sodium (salt) intake is a key determinant of blood pressure, and reducing sodium intake has emerged as an important target for population-based interventions to prevent CVD. However, there is considerable uncertainty about the optimal level of sodium intake that is associated with lowest CV risk, and whether optimal levels differ for different populations and individuals. International and national guidelines recommend low sodium intake (<2.3g/day, or lower) in all persons, and advocate a population-wide approach to reducing sodium. Most of the world's population (~95%) consume between 3 and 6g/day of sodium (mean intake 4.0g/day), which means that most people will require a major change to their diet, to achieve the guideline target (<2g/day). While there is convincing evidence that high sodium intake (>5g/day) is associated with an increased risk of CVD, compared to low or moderate intake, the evidence that low sodium intake (<2.0g/day) is associated with a lower risk of CVD than moderate intake (2.0-5g/day) is inconsistent and inconclusive. The investigators plan to conduct a Phase IIb clinical trial to evaluate the role of low sodium intake (versus moderate) on cardiovascular biomarkers.
The primary aim of the study was to investigate the acute effect of ginger drink consumption on the risk markers of cardiovascular disease.
To collect information about treatment for severe aortic stenosis (AS), which affects the aortic valve in the heart. Aortic stenosis is a narrowing of the aortic valve opening, which decreases blood flow from the heart and causes symptoms such as chest pain, fainting and shortness of breath. The preferred treatment for severe aortic stenosis is aortic valve replacement surgery.
