Filter by:The overall objective of the proposed cluster randomized trial is to test whether implementation of protocol-based integrated care will improve CVD risk factors (glycated hemoglobin [HbA1C], systolic blood pressure [SBP], and LDL-cholesterol) over 18 months and reduce major CVD events (non-fatal stroke, non-fatal myocardial infarction, hospitalized heart failure, and CVD mortality) over 3 years among patients with type 2 diabetes and additional CVD risk factors or clinical CVD compared to usual team-based care in community clinics in Xiamen, China.
Hypertensive heart disease (HHD) is a heart condition that is caused by chronic exposure to high blood pressure. In patients with HHD, abnormalities in the way heart muscle relaxes and how heart chambers passively fill with blood (diastolic dysfunction) can occur that may be detected on echocardiography (echo), which is a standard clinical method to examine heart structure and function using reflected sound waves. Investigators propose to develop a digital auscultation system or electronic stethoscope based on wireless sensor node technique. Investigators hypothesize that the heart sounds measurements detected by electronic stethoscope can be used to detect heart diastolic dysfunction in HHD .
The existing scientific evidence from both in vitro and clinical trials supports the notion that polyphenols can modulate platelet function. Beyond being central players in haemostasis and thrombosis, platelets have crucial roles in the development of atherosclerosis, mediated through their interactions with monocytes and endothelial cells. Disturbed platelet function correlates with other risk factors, including hypertension and obesity, and the progression of cardiovascular diseases (CVD), postulating platelets as rational targets in CVD prevention. Thus, the effects of polyphenols on disturbed platelet function would contribute to their pleiotropic beneficial effects of on cardiovascular health. Aronia juice is a rich source of polyphenols including anthocyanins, procyanidins, phenolic acids and flavonols. However, there is no clinical evidence on the effects of aronia juice consumption on platelet function and related CVD factors. The purpose of this study is to investigate the effects of Aronia juice polyphenols on platelet function and other CVD risk factors in subjects with moderate CVD risk.
This study will evaluate a complex intervention based on a patient management tool (PMT), combined with educational outreach to primary care doctors, nurses and other health workers, in the Brazilian city of Florianopolis. The intervention is aimed at improving the quality of primary health care and health outcomes, in adults with diabetes and cardiovascular disease (CVD). The effectiveness of the intervention will be assessed by randomly allocating 48 primary care clinics to receive the intervention or not, and comparing patient and clinic level endpoints that reflect the health and quality of care provided over the following year. About 11000 patients known to have been diagnosed with diabetes mellitus and 32000 with CVD (defined as having a diagnosis of hypertension, ischemic heart disease, heart failure or cerebrovascular disease) in participating clinics will be included in the study. About 7800 of them have diagnoses of both CVD and stroke. The primary endpoints will be 1. Number of participants in whom at least one of the following tests was recorded: body mass index, plasma glucose, serum cholesterol, electrocardiogram, and 2. in participants with a diagnosis of hypertension recorded previously, average systolic blood pressure recorded. Secondary endpoints will include the individual components of the composite scores, health measures (hospital admissions and deaths), and indicators of appropriate diagnosis of comorbid conditions such as depression. Eligible patients will be identified and outcomes measured using electronic medical records.
This study is to compare the pharmacodynamics of a Fixed Dose Combination Pill AAR (acetylsalicylic acid 100 mg, atorvastatin 40 mg and ramipril 10 mg) and the respective reference products, atorvastatin (Lipitor®) 40 mg and ramipril (Altace®) 10 mg.
First, the aim of the study was to evaluate the usefulness of echocardiographic parameters for detecting pulmonary hypertension (PH) in patients with advanced lung disease referred for lung transplantation. Second, to assess the prevalence of PH and to identify which hemodynamic, echocardiographic, pulmonary functional test, exercise capacity and biochemical parameters (especially NT-proBNP) have an impact on survival in a cohort of patients with severe lung diseases referred for lung transplantation.
The purpose of this study is to evaluate whether a new model of health care for chronic patients, based on Case Management and guided by a nurse which targets the patient´s risk, is more effective than usual care at Primary Health care in Chile. Additionally, this intervention would provide a better quality of care and a more efficient health provision.
To evaluate the safety and efficacy of targeted renal sympathetic denervation using SyMapCath I® and SYMPIONEER S1® Stimulator/ Generator in patients with essential hypertension for at least 6 months of the disease history and pharmacotherapy, however, their blood pressure still cannot be controlled, then after standardized antihypertensive drug therapy (at least two drugs) for at least 28 days, office systolic blood pressure is still ≥ 150mmHg, ≤180mmHg.
This trial evaluates the effect of providing primary care patients with free and convenient access to a set of essential medicines. Half of the participants will receive free and convenient access to these essential medicines, while the other half will have usual access to medicines.
The purpose of this study is to learn more about the regulation of the veins of the abdomen by the autonomic (involuntary) nervous system, and how this may affect high blood pressure. Normally, the autonomic nervous system controls how much blood flows in the veins. In people with high blood pressure, however, the autonomic nervous system is changed. This change may affect the way blood flows in the veins of the abdomen which may play a role in their high blood pressure. About 32 participants will be screened for the study. The investigators estimate 16 will be eligible to participate in all of the study days.
