The Scandinavian Simvastatin Survival Study, was a multicentre, randomized, double-blind, placebo-controlled clinical trial, which provided the initial data that supported the use of the cholesterol-lowering drug, simvastatin, in people with a moderately raised cholesterol and coronary heart disease (CHD); that is people who had previously had a heart attack or angina. The study was sponsored by the pharmaceutical company Merck and enrolled 4,444 people from 94 centres in Scandinavia.
Rosiglitazone is an antidiabetic drug in the thiazolidinedione class. It works as an insulin sensitizer, by binding to the PPAR in fat cells and making the cells more responsive to insulin. It is marketed by the pharmaceutical company GlaxoSmithKline (GSK) as a stand-alone drug or for use in combination with metformin or with glimepiride. First released in 1999, annual sales peaked at approximately $2.5-billion in 2006; however, following a meta-analysis in 2007 that linked the drug's use to an increased risk of heart attack, sales plummeted to just $9.5-million in 2012. The drug's patent expired in 2012.
Coronary thrombosis is defined as the formation of a blood clot inside a blood vessel of the heart. This blood clot may then restrict blood flow within the heart, leading to heart tissue damage, or a myocardial infarction, also known as a heart attack.
The British Doctors' Study was a prospective cohort study which ran from 1951 to 2001, and in 1956 provided convincing statistical evidence that tobacco smoking increases risk of lung cancer.
The University of Ottawa Heart Institute (UOHI) (French: Institut de cardiologie de l'Université d'Ottawa ) is Canada's largest cardiovascular health centre. It is located in Ottawa, Ontario, Canada. It began as a department in The Ottawa Hospital, and since has evolved into Canada's only complete cardiac centre, encompassing prevention, diagnosis, treatment, rehabilitation, research, and education.
Bivalirudin (Bivalitroban), sold under the brand names Angiomax and Angiox and manufactured by The Medicines Company, is a specific and reversible direct thrombin inhibitor (DTI).
Troponin I is a cardiac and skeletal muscle protein family. It is a part of the troponin protein complex, where it binds to actin in thin myofilaments to hold the actin-tropomyosin complex in place. Troponin I prevents myosin from binding to actin in relaxed muscle. When calcium binds to the troponin C, it causes conformational changes which lead to dislocation of troponin I. Afterwards, tropomyosin leaves the binding site for myosin on actin leading to contraction of muscle. The letter I is given due to its inhibitory character. It is a useful marker in the laboratory diagnosis of heart attack. It occurs in different plasma concentration but the same circumstances as troponin T - either test can be performed for confirmation of cardiac muscle damage and laboratories usually offer one test or the other.
Medical statistics deals with applications of statistics to medicine and the health sciences, including epidemiology, public health, forensic medicine, and clinical research. Medical statistics has been a recognized branch of statistics in the United Kingdom for more than 40 years, but the term has not come into general use in North America, where the wider term 'biostatistics' is more commonly used. However, "biostatistics" more commonly connotes all applications of statistics to biology. Medical statistics is a subdiscipline of statistics.
It is the science of summarizing, collecting, presenting and interpreting data in medical practice, and using them to estimate the magnitude of associations and test hypotheses. It has a central role in medical investigations. It not only provides a way of organizing information on a wider and more formal basis than relying on the exchange of anecdotes and personal experience, but also takes into account the intrinsic variation inherent in most biological processes.
The Thrombolysis In Myocardial Infarction (TIMI) Study Group, is an academic research organization (ARO) affiliated with Brigham and Women's Hospital and Harvard Medical School with a focus in the field of cardiovascular disease. The group has its headquarters in Boston, Massachusetts.
The Glasgow Clinical Research Facility is a research centre at the Queen Elizabeth University Hospital in Govan, Glasgow, Scotland.
The Glasgow Clinical Trials Unit (CTU) is a collaborative research establishment in Glasgow, Scotland. It comprises the Glasgow Clinical Research Facility, the Robertson Centre for Biostatistics and Greater Glasgow and Clyde NHS R&D division.
The Epidemiology Data Center (EDC) is recognized as an official University Center at the University of Pittsburgh; and is part of the Department of Epidemiology at the University of Pittsburgh Graduate School of Public Health. The EDC was formed in 1980 by Katherine M. Detre, M.D., Dr.P.H., and is currently under the co-direction of Maria Mori Brooks, Ph.D., Steven H. Belle, Ph.D. and Stephen R. Wisniewski, Ph.D.
Sir Rory Edwards Collins FMedSci FRS is a British physician who is Professor of Medicine and Epidemiology at the Clinical Trial Service Unit within the University of Oxford, the head of the Nuffield Department of Population Health and a Fellow of Green Templeton College, Oxford. His work has been in the establishment of large-scale epidemiological studies of the causes, prevention and treatment of heart attacks, other vascular disease, and cancer, while also being closely involved in developing approaches to the combination of results from related studies ("meta-analyses"). Since September 2005, he has been the Principal Investigator and Chief Executive of the UK Biobank, a prospective study of 500,000 British people aged 40–69 at recruitment.
A myocardial infarction (MI), commonly known as a heart attack, occurs when blood flow decreases or stops in one of the coronary arteries of the heart, causing infarction to the heart muscle. The most common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck or jaw. Often such pain occurs in the center or left side of the chest and lasts for more than a few minutes. The discomfort may occasionally feel like heartburn.
Electrocardiography in suspected myocardial infarction has the main purpose of detecting ischemia or acute coronary injury in emergency department populations coming for symptoms of myocardial infarction (MI). Also, it can distinguish clinically different types of myocardial infarction.
Ian Ford [ FRSE FRCP(Glas) FSCT ] is a professor of biostatistics and a director of the Robertson Centre for Biostatistics, and a former Dean of Faculty of Information and Mathematical Sciences, at the University of Glasgow.
Cariporide is a selective Na+/H+ exchange inhibitor. Cariporide has been shown to actively suppress the cell death caused by oxidative stress.
The Cardiac Arrhythmia Suppression Trial (CAST) was a double-blind, randomized, controlled study designed to test the hypothesis that suppression of premature ventricular complexes (PVC) with class I antiarrhythmic agents after a myocardial infarction (MI) would reduce mortality. It was conducted between 1986 and 1989 and included over 1700 patients in 27 centres. The study found that the tested drugs increased mortality instead of lowering it as was expected. The publication of these results in 1991/92, in combination with large follow-up studies for drugs that had not been tested in CAST, led to a paradigm shift in the treatment of MI patients. Class I and III antiarrhythmics are now only used with extreme caution after MI, or they are contraindicated completely. Heart Rhythm Society Distinguished Scientist D. George Wyse was a member of the CAST trial's steering and executive committees.
Sheila Macdonald Bird OBE FRSE FMedSci is a Scottish biostatistician whose assessment of misuse of statistics in the British Medical Journal (BMJ) and BMJ series ‘Statistics in Question’ led to statistical guidelines for contributors to medical journals. Bird's doctoral work on non-proportional hazards in breast cancer found application in organ transplantation where beneficial matching was the basis for UK's allocation of cadaveric kidneys for a decade. Bird led the Medical Research Council (MRC) Biostatistical Initiative in support of AIDS/HIV studies in Scotland, as part of which Dr A. Graham Bird and she pioneered Willing Anonymous HIV Surveillance (WASH) studies in prisons. Her work with Cooper on UK dietary bovine spongiform encephalopathy (BSE) exposure revealed that the 1940–69 birth cohort was the most exposed and implied age-dependency in susceptibility to clinical vCJD progression from dietary BSE exposure since most vCJD cases were younger, born in 1970–89. Bird also designed the European Union's robust surveillance for transmissible spongiform encephalopathies in sheep which revolutionised the understanding of scrapie.
Major adverse cardiovascular events is a composite endpoint frequently used in cardiovascular research. Despite widespread use of the term in clinical trials, the definitions of MACE can differ, which makes comparison of similar studies difficult.
