Filter by:The association between alcohol consumption and cardiovascular disease (CVD) has mostly been examined using broad endpoints or cause-specific mortality. The purpose of our study is to compare the effect of alcohol consumption in the aetiology of a range of cardiovascular disease phenotypes.
The purpose of this study is to compare the pharmacokinetic characteristics and safety of dilatrend SR capsule 32mg and Dilatrend tablet 25mg in healthy male subjects.
Cardiovascular disease (CVD) is an important public health problem that affects millions of people worldwide. Associations between risk factors, such as smoking, dyslipidaemia or hypertension, and prevalent CVD are well documented. However, few studies have investigated associations with onset of disease. The initial manifestation of CVD, for example an episode of unstable angina, is important because it influences the prognosis, the quality of life and the management of disease. Furthermore, the extent to which social deprivation, alcohol consumption or atrial fibrillation affects presentation of CVD is poorly understood and deserves further consideration. Most previous studies have considered CVD as a single entity. However, differences in aetiology between coronary phenotypes suggest that risk factors may not be shared across specific coronary phenotypes and their relative importance is likely to differ for each phenotype. Gaining knowledge of these differences could provide insights into the pathophysiology of specific forms of CVD and could eventually lead to modification of recommendations for patient management and disease prevention. We propose to use the linkage of the national registry of coronary events to general practice records in the Clinical Practice Research Database (CPRD), to investigate whether demographic, behavioral, and clinico-metabolic risk factors differentially influence the onset of specific types of CVD.
CTOs are common among patients with angina, and are detected in around 20% of patients undergoing coronary angiography. Treatment of CTO has been found to constitute only 7% of PCI practice on average. One of the reasons for the under-presentation of CTOs in PCI target lesions is the lack of evidence-based medical data on treatment indications, and the continued low level of accepted evidence for the treatment of CTOs by PCI in PCI guidelines. Patients with a CTO represent patients with stable coronary artery disease. The COURAGE trial comparing PCI with optimal medical therapy in stable coronary disease did not show a difference in mortality or myocardial infarction between the two treatment options. However, CTOs were not included in the COURAGE trial. But that trial did confirm the superiority of PCI over OMT in controlling symptoms of angina, with a high cross-over rate to PCI. Whether PCI for CTO is superior to OMT in reducing MACE in those patients with a large ischaemic burden has never been tested in a randomized controlled trial. While there is compelling evidence from registry studies of a clinical and prognostic benefit following successful PCI of CTO compared with PCI failure, there has been no randomized controlled trial of contemporary PCI using drug-eluting stents versus optimal medical therapy. The COURAGE trial nuclear sub-study confirms both that prognosis is closely related to the extent of residual ischaemia and that PCI is more effective in reducing residual ischaemia than optimal medical therapy alone. This confirms earlier retrospective data suggesting that the benefit of PCI is greatest in patients with moderate (10-20%) or severe (>20%) ischaemia. Study hypothesis: PCI with Biolimus eluting stent implantation plus OMT will be superior to OMT alone in improving health status at 12-month follow-up, and will be noninferior with respect to the composite of all cause death/ non fatal MI at 36-month follow up, in patients with a CTO in an epicardial coronary artery >2.5 mm diameter and chronic stable angina with evidence of ischemia and viability in the territory subtended by the CTO
The purpose of this study is to evaluate the effect of Danhong Injection on the relief of angina with the use of the Seattle Angina Questionnaire among patients with stable angina patients
Ranolazine is an effective and remarkably safe agent for the treatment of patients with chronic stable angina, but its inhibition of voltage gated potassium channels and electrocardiogram (EKG) corrected QT (QTc) prolongation properties have lead many to question its safety when combined with antiarrhythmic drugs. The investigators have proposed a study to determine the safety of ranolazine in patients with chronic stable angina who also take amiodarone. And are conducting a prospective single-center randomized single-blinded placebo controlled trial to run out of our large cardiology practice setting at Cardiovascular Consultants of Nevada. The hypothesis is that there will be no difference in the ventricular arrhythmia burden. The primary outcome will be the measurement of ventricular arrhythmia episodes on serial holter monitor and other serially acquired recordings (such as electrocardiogram, pacemaker or implantable defibrillator (ICD) data, and stress test data) over a three month trial period.
The objectives of this study are to evaluate the efficacy, pharmacological activities and safety of STA-2 in the treatment of chronic stable angina.
Allopurinol is a drug commonly used to treat gout. However recent studies have shown it has the potential to help improve oxygen supply to heart muscle. In this study the Investigators aim to find out if allopurinol slows down the onset of angina symptoms, as seen by a doctor on a tracing of the heart (ECG- electrocardiogram), for patients who have been diagnosed with heart disease, when exercising on a treadmill. The Investigators are also are trying to figure out the best dose of allopurinol to use and to see how quickly it begins working. To do this the investigators will recruit patients with angina, exercise them on a treadmill after giving different doses of allopurinol and see if there is an improvement in their time to bring on angina symptoms and signs. Patients recruited to this trial will receive three different treatment regimes over a six week period. Each treatment regime will last for one week with a one week rest period between each regime. This will involve up to eleven visits to Ninewells Medical School, Dundee for testing.
This study is to determine the anti-anginal and anti-ischemic effect of k-channel opener, nicorandil in patients of chronic stable angina.
This study is designed to evaluate dose-proportionality of Dilatrend SR 8mg, 16mg, 32mg, 64mg, 128mg in healthy male volunteers.
