The primary aim of this study is to increase our understanding of care-seeking behavior surrounding heart attacks or acute coronary syndromes [ACS]. This study uses an internet based survey to ask individuals how they obtained medical care in the midst of a heart attack. At present, care-seeking delay among individuals stricken with a heart attack prevents them from obtaining the full therapeutic benefit of hospital based medical care in a timely manner to reduce the long term health consequences of a heart attack. By using a self-tailoring survey instrument the study attempts to take into consideration the complex social processes by which the individual and their family make decisions to seek medical care for symptoms of a heart attack. The study is designed to obtain a national sample of ACS care-seeking behavior in the United States.
Fondaparinux, a synthetic and specific factor Xa inhibitor, was granted an ACS indication by Health Canada in March 2007 and by the EMEA in September 2007. Among ACS patients, fondaparinux is indicated for the treatment of UA/NSTEMI in patients for whom urgent PCI (within 2 hours) is not indicated, and for the treatment of STEMI in patients who are managed with thrombolytics or who are initially to receive no other form of reperfusion therapy. The approved prescribing information for fondaparinux in ACS provides recommendations for use in patients undergoing PCI. The purpose of this study is to evaluate physician adherence to this prescribing information in ACS patients treated with fondaparinux and who undergo PCI. The primary endpoint is the proportion of patients with ACS treated with fondaparinux, for whom the prescribing information during PCI was followed (i.e., adjunctive anticoagulant therapy administered at the time of PCI). Measurement of the effectiveness or safety of fondaparinux use in ACS patients is not within the scope of this study. ARIXTRA® is a trademark of the GlaxoSmithKline group of companies.
OBJECTIVE It is the objective of the REMEDEE OCT study to assess vascular healing after deployment of the Abluminal Sirolimus Coated Bio-Engineered Stent (Combo Bio-Engineered Sirolimus Eluting Stent) in patients with Acute Coronary Syndrome (ACS) with single de novo native coronary artery lesions ranging in diameter from ≥2.5 mm to ≤3.5 mm and ≤ 20 mm in length. STUDY DESIGN The REMEDEE OCT study is a prospective, multicenter, randomized study designed to enroll 60 patients with ACS who will be randomized 1:1 to be treated with the Combo stent versus the commercially available everolimus eluting stent (Xience V or Promus). Patients will receive Optical Coherence Tomography (OCT) and Quatitative Coronary Angiography (QCA) follow-up imaging at 60 days post procedure. Clinical follow-up is scheduled at 30, 60, 180, 360 and 540 days. Furthermore, QCA and OCT will also be performed at baseline in all participants of the study.
Various elements of patient history are checked and entered in the admission Case Recor Form (CRF). Three risk scores are calculated out of these elements, combined with physical examination, laboratory values and ECG-findings. The primary aim is to assess the positive and negative predictive values for a cardiovascular event of the three risk scores for chest pain patients. Secondary aim is to assess the sensitivity and specificity of various elements in the patient history for an acute coronary syndrome.
The burden of chronic, non-communicable disease, of which cardiovascular disease comprises a significant component, has increased rapidly and substantially in China over recent years. Over the coming decades China is predicted to experience a 69% increase in acute coronary disease(ACS), amounting to nearly 8 million additional events. A recent randomized trial of more than 15,000 patients with acute coronary syndromes, the second phase of Clinical Pathway for acute coronary syndromes in China (CPACS-2) study, showed that a quality improvement initiative could improve aspects of hospital care, including the proportion of patients discharged on appropriate medication. The study also identified a number of barriers to improved care including out of pocket costs and administration systems. However, the study was not able to determine the impact on clinical outcomes or the cost-effectiveness of the intervention. The aim of the third phase of the Clinical Pathway for acute coronary syndromes in China (CPACS-3) study is to determine whether a complex intervention comprising a clinical pathway for ACS management in combination with a number of physician and patient-oriented education tools can improve the quality of care and health outcomes among ACS patient admitted to resource-limited (provincial) hospitals. The effectiveness of the intervention will be evaluated using a cluster randomized trial (stepped wedge design) of ACS patients admitted to 104 hospitals in China. The study will incorporate two additional components (1) a qualitative substudy to identify the barriers and enablers to improved care and (2) a study comparing the cost-effectiveness of the intervention compared to usual care, from the perspective of the health care provider. The study will be conducted in conjunction with the Chinese Ministry of Health and the Chinese Society of Cardiology. The findings from CPACS3 will be able to inform health policy-makers about the extent to which quality improvement initiatives can reduce the risk of death and disability among the millions of ACS patients admitted to hospitals in China each year.
The objective is to investigate whether in acute coronary syndrome patients the cardiac risk profile will improve with 2 new extended cardiac rehabilitation interventions and if these patients maintain healthier life style habits and a more active life style compared to patients randomized to standard cardiac rehabilitation.
The purpose of this study is to compare vascular healing of the stented segment after deployment of new PRO-Kinetic drug eluting stent and Endeavor Resolute zotarolimus-eluting stent in patients with acute coronary syndromes requiring percutaneous coronary intervention.
To demonstrate that a strategy of fast genetic testing performed in outpatient clinic allows to select adequately one of the 2 antiplatelet treatments approved in the same indication (ACS with PCI - prasugrel 10mg MD or clopidogrel 75mg MD). Patients will reach similar levels of platelet inhibition with the 2 different thienopyridines suggesting optimal risk/benefit ratio in most patients with individualized therapy.
Patients undergoing multivessel off-pump coronary bypass surgery (OPCAB) inevitably experience cumulative ischemia-reperfusion injury at myocardium. Glucose-insulin-potassium (GIK) is a potentially useful adjunct to myocardial protection. This study was designed to evaluate the effects of GIK infusion on myocardium in patients undergoing OPCAB. Patients undergoing OPCAB with acute coronary syndrome are randomly assigned to GIK or Control group. The trial is double-blind and conducted at a single center.
