Angina, also known as angina pectoris, is chest pain or pressure, usually caused by insufficient blood flow to the heart muscle (myocardium). It is most commonly a symptom of coronary artery disease.
Interventional cardiology is a branch of cardiology that deals specifically with the catheter based treatment of structural heart diseases. Andreas Gruentzig is considered the father of interventional cardiology after the development of angioplasty by interventional radiologist Charles Dotter.
Dressler syndrome is a secondary form of pericarditis that occurs in the setting of injury to the heart or the pericardium. It consists of fever, pleuritic pain, pericarditis and/or pericardial effusion.
Acute coronary syndrome (ACS) is a syndrome due to decreased blood flow in the coronary arteries such that part of the heart muscle is unable to function properly or dies. The most common symptom is centrally located pressure-like chest pain, often radiating to the left shoulder or angle of the jaw, and associated with nausea and sweating. Many people with acute coronary syndromes present with symptoms other than chest pain, particularly women, older people, and people with diabetes mellitus.
Unstable angina is a type of angina pectoris that is irregular or more easily provoked. It is classified as a type of acute coronary syndrome.
P2Y12 is a chemoreceptor for adenosine diphosphate (ADP) that belongs to the Gi class of a group of G protein-coupled (GPCR) purinergic receptors. This P2Y receptor family has several receptor subtypes with different pharmacological selectivity, which overlaps in some cases, for various adenosine and uridine nucleotides. The P2Y12 receptor is involved in platelet aggregation and is thus a biological target for the treatment of thromboembolisms and other clotting disorders. Two transcript variants encoding the same isoform have been identified for this gene.
Door-to-balloon is a time measurement in emergency cardiac care (ECC), specifically in the treatment of ST segment elevation myocardial infarction. The interval starts with the patient's arrival in the emergency department, and ends when a catheter guidewire crosses the culprit lesion in the cardiac cath lab. Because of the adage that "time is muscle", meaning that delays in treating a myocardial infarction increase the likelihood and amount of cardiac muscle damage due to localised hypoxia, ACC/AHA guidelines recommend a door-to-balloon interval of no more than 90 minutes. As of 2006 in the United States, fewer than half of STEMI patients received reperfusion with primary percutaneous coronary intervention (PCI) within the guideline-recommended timeframe. It has become a core quality measure for the Joint Commission on Accreditation of Healthcare Organizations (TJC).

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. Other symptoms may include shortness of breath, nausea, feeling faint, a cold sweat, feeling tired, and decreased level of consciousness. About 30% of people have atypical symptoms. Women more often present without chest pain and instead have neck pain, arm pain or feel tired. Among those over 75 years old, about 5% have had an MI with little or no history of symptoms. An MI may cause heart failure, an irregular heartbeat, cardiogenic shock or cardiac arrest.

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.
Management of acute coronary syndrome is targeted against the effects of reduced blood flow to the affected area of the heart muscle, usually because of a blood clot in one of the coronary arteries, the vessels that supply oxygenated blood to the myocardium. This is achieved with urgent hospitalization and medical therapy, including drugs that relieve chest pain and reduce the size of the infarct, and drugs that inhibit clot formation; for a subset of patients invasive measures are also employed. Basic principles of management are the same for all types of acute coronary syndrome. However, some important aspects of treatment depend on the presence or absence of elevation of the ST segment on the electrocardiogram, which classifies cases upon presentation to either ST segment elevation myocardial infarction (STEMI) or non-ST elevation acute coronary syndrome (NST-ACS); the latter includes unstable angina and non-ST elevation myocardial infarction (NSTEMI). Treatment is generally more aggressive for STEMI patients, and reperfusion therapy is more often reserved for them. Long-term therapy is necessary for prevention of recurrent events and complications.
Jean-Claude Tardif is the Director of the Research Center at the Montreal Heart Institute and Professor of Medicine at the University of Montreal. He received his medical degree (MD) in 1987 from the University of Montreal and specialized in cardiology and research in Montreal and Boston until 1994. Dr. Tardif holds the Canada Research Chair in personalized medicine and the University of Montreal endowed research chair in atherosclerosis. He is also the Scientific Director of the Montreal Health Innovations Coordinating Center (MHICC).
Kounis syndrome is defined as acute coronary syndrome caused by an allergic reaction or a strong immune reaction to a drug or other substance. It is a rare syndrome with authentic cases reported in 130 males and 45 females, as reviewed in 2017; however, the disorder is suspected of being commonly overlooked and therefore much more prevalent. Mast cell activation and release of inflammatory cytokines as well as other inflammatory agents from the reaction leads to spasm of the arteries leading to the heart muscle or a plaque breaking free and blocking one or more of those arteries.
Prof. Dr. Johann Bauersachs is a German internist, cardiologist, and full professor at the Hannover Medical School. He is widely recognized for his scholarly contributions to the domains of acute coronary syndrome, left ventricular repair and remodelling following ischemia, and acute and chronic heart failure.

George "Rick" Stouffer is an American cardiologist who is Chief of the Division of Cardiology at the University of North Carolina Medical Center, where he is a practicing interventional cardiologist. Stouffer was awarded the Ernest and Hazel Craige Distinguished Professorship of Medicine in 2018; prior to that he was the Henry A. Foscue Distinguished Professor of Medicine.

John A. Ambrose is an American physician who is an expert in coronary artery disease. He is one of the pioneers in acute coronary syndromes having published over 40 articles in the cardiology literature between 1985 and 2000 on their pathogenesis. He has also published on cigarette smoking and cardiovascular disease. Working with his PhD candidate, Rajat Barua, utilizing a novel in vitro model, they described the effects of cigarette smoking on nitric oxide biosynthesis, endothelial function, and endothelial-derived fibrinolytic and antithrombotic factors. Their 2004 update on cigarette smoking and cardiovascular disease published in the Journal of the American College of Cardiology has been referenced over 2,100 times as of 2020. Ambrose is a Professor of Clinical Medicine at the University of California, San Francisco. He was also a Director of the Cardiac Catheterization Laboratory at Mount Sinai Hospital and received a National Leadership Award from the National Republican Congressional Committee.
