Filter by:The purpose of this study is to make a cohort event monitoring to see whether and how Shenmai injection in hospital results in adverse events or adverse drug reactions.
This study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in October 2011. It was funded by China major scientific and technological specialized project for 'significant new formulation of new drugs'. Kudiezi is kind of Chinese Medicine injection used for treating coronary heart disease and angina pectoris in many Chinese hospitals. The purpose of this study is to determine adverse drug events or adverse drug reaction in large sample size 30,000 patients.

Cardiopulmonary bypass surgery is associated with extensive blood loss in upto 20% of patients. Tranexamic acid (TXA) is a routinely administered antifibrinolytic agent that reduces blood loss and blood transfusion requirement. However, standard dosing of TXA in patients suffering from renal dysfunction and undergoing cardiopulmonary bypass surgery may lead to higher blood concentration of TXA when compared to the patients with normal renal function. Solid phase microextraction (SPME) is a fast and simple method to measure TXA levels. This prospective study on cadiac surgical patients undergoing cardiopulmonary bypass aims to study the pharmacokinetics of TXA in patients with renal dysfunction. Two patient groups will be studied who will receive either TXA 50mg/kg bolus or BART regimen (30 mg/kg, 16 mg/kg/h + 2 mg/kg pump prime) depending on the type of cardiac surgical procedure and bleeding risk. Hypothesis: Standard dosing of TXA used in cardiac surgery result in higher blood concentration of TXA in patients with renal dysfunction when compared to patients with normal renal function.
The purpose of this study is to evaluate the safety and cholesterol lowering effects of MPSK3169A when given as subcutaneous (SC) injections over a 24-week period to patients with a high risk of cardiovascular events and LDL-c levels well above goal.
The study involves documenting the effects of inhaled nitric oxide upon ventricular-arterial coupling in patients with congenital heart disease and passive pulmonary blood flow. Consenting patients undergoing a clinically-indicated cardiac catheterization will be given inhaled nitric oxide for 10 minutes while intraventricular pressure-volume analysis will be make via conduction catheters.
The objective of this clinical trial is to evaluate whether a computerized depression treatment, delivered before the onset of heart disease, reduces the risk of heart disease in the future. Participants in this trial will be primary care patients who are depressed but do not have a history of heart disease. Half of these patients will receive a standard treatment (usual care), and the other half will receive eight weeks of an evidence-based psychological treatment called Beating the Blues®, which is a computerized, cognitive behavioral treatment program for depression. To evaluate change in heart disease risk, the investigators will measure the functioning of the arteries using ultrasound before and after the treatment. It is hypothesized that patients who receive Beating the Blues® will show greater improvements in both depression and artery function than patients who receive standard treatment.
B-type natriuretic Peptide (BNP) is a cardiac hormone secreted from the cardiac myocytes in response to volume load. Plasma levels of BNP, as measured by immunoassay methods, are elevated in patients with heart diseases. However, the biological effects of BNP are blunted in heart failure and other cardiac conditions. Moreover, the peptide levels are also elevated in non cardiac conditions such as the neonatal period, sepsis and renal failure. Recent investigations suggest alteration of the peptide molecular structure in heart failure. These alterations may explain, at least partially, the reduced biological activities of BNP in heart failure. Immunoreactive BNP and NT-proBNP have been identified in human urine. It has been suggested that urinary BNP correlates with plasma BNP, and may serve as a non-invasive measure for this cardiac marker. It is unclear what BNP fractions are cleared in the urine in health and disease. The aim of the proposed studies is to elucidate precisely the molecular form of BNP in various disease and specific physiological states in plasma and urine of infants and children.
The underlying hypothesis is that whole body cholesterol - including cholesterol present in tissues that cannot be measured by standard blood tests - is related to heart disease risk. Endogenous cholesterol will be labeled with an intravenous infusion of one type of cholesterol tracer and dietary cholesterol will be labeled with another. These tracers will be used to measure how fast cholesterol is synthesized and excreted using mass spectrometry to distinguish the tracers. Data will be related to circulating biomarkers (blood tests) and to the thickness of the lining of the carotid artery. The effect of the drug ezetimibe on these processes will also be determined. Successful completion of this study will give us more knowledge about cholesterol metabolism that may be useful in designing new drugs and treatments for patients with heart disease, especially those that are already receiving maximum amounts of current medications.
The goal of this study is to find out if there is any association between a mother's exposure to bacteria that normally causes "strep throat" and her baby's developing heart disease/heart defect.
