Cardiology is the study of the heart. Cardiology is a branch of medicine that deals with disorders of the heart and the cardiovascular system. The field includes medical diagnosis and treatment of congenital heart defects, coronary artery disease, heart failure, valvular heart disease, and electrophysiology. Physicians who specialize in this field of medicine are called cardiologists, a sub-specialty of internal medicine. Pediatric cardiologists are pediatricians who specialize in cardiology. Physicians who specialize in cardiac surgery are called cardiothoracic surgeons or cardiac surgeons, a specialty of general surgery.
Echocardiography, also known as cardiac ultrasound, is the use of ultrasound to examine the heart. It is a type of medical imaging, using standard ultrasound or Doppler ultrasound. The visual image formed using this technique is called an echocardiogram, a cardiac echo, or simply an echo.
Alfred Blalock was an American surgeon most noted for his work on the medical condition of shock as well as tetralogy of Fallot – commonly known as blue baby syndrome. He created, with assistance from his research and laboratory assistant Vivien Thomas and pediatric cardiologist Helen Taussig, the Blalock–Thomas–Taussig shunt, a surgical procedure to relieve the cyanosis from tetralogy of Fallot. This operation ushered in the modern era of cardiac surgery. He worked at both Vanderbilt University and Johns Hopkins University, where he studied medicine and later served as chief of surgery. He is known as a medical pioneer who won various awards, including Albert Lasker Clinical Medical Research Award. Blalock was also nominated several times for the Nobel Prize in Medicine.
A cardiac stress test is a cardiological examination that evaluates the cardiovascular system's response to external stress within a controlled clinical setting. This stress response can be induced through physical exercise or intravenous pharmacological stimulation of heart rate.
In cardiology, an Austin Flint murmur is a low-pitched rumbling heart murmur which is best heard at the cardiac apex. It can be a mid-diastolic or presystolic murmur. It is associated with severe aortic regurgitation, although the role of this sign in clinical practice has been questioned.
Helen Brooke Taussig was an American cardiologist, working in Baltimore and Boston, who founded the field of pediatric cardiology. She is credited with developing the concept for a procedure that would extend the lives of children born with Tetralogy of Fallot. This concept was applied in practice as a procedure known as the Blalock-Thomas-Taussig shunt. The procedure was developed by Alfred Blalock and Vivien Thomas, who were Taussig's colleagues at the Johns Hopkins Hospital.
Uhl anomaly is a rare cardiac malformation that was first identified by Dr. Henry Uhl in 1952. It is characterized by the absence of the right ventricle (RV) myocardium, either entirely or partially, and the replacement of the RV myocardium by nonfunctional fibroelastic tissue that resembles parchment. As of 2010 less than 100 cases have been reported in literature.
The cardiac index (CI) is a hemodynamic measure that represents the cardiac output (CO) of an individual divided by their body surface area (BSA), expressed in liters per minute per square meter (L/min/m²). This parameter provides a more accurate assessment of heart function relative to the size of the individual, as opposed to absolute cardiac output alone. Cardiac index is crucial in assessing patients with heart failure and other cardiovascular conditions, providing insight into the adequacy of cardiac function in relation to the individual's metabolic needs.
Avijit Lahiri is a researcher in cardiology in the UK.
Cardiac magnetic resonance imaging, also known as cardiovascular MRI, is a magnetic resonance imaging (MRI) technology used for non-invasive assessment of the function and structure of the cardiovascular system. Conditions in which it is performed include congenital heart disease, cardiomyopathies and valvular heart disease, diseases of the aorta such as dissection, aneurysm and coarctation, coronary heart disease. It can also be used to look at pulmonary veins.
Howard Apfel is an American-Israeli rabbi and cardiologist practicing medicine at Columbia University Medical Center.
Multan Institute of Cardiology (MIC), is a hospital located in Multan city in Pakistan. It was established by Chaudhry Pervaiz Elahi, the former chief minister of Punjab province, in 2005.
Cardiac imaging refers to minimally invasive imaging of the heart using ultrasound, magnetic resonance imaging (MRI), computed tomography (CT), or nuclear medicine (NM) imaging with PET or SPECT. These cardiac techniques are otherwise referred to as echocardiography, Cardiac MRI, Cardiac CT, Cardiac PET and Cardiac SPECT including myocardial perfusion imaging.
Richard Starr Ross was an American cardiologist and served as Dean of Johns Hopkins University's School of Medicine from 1975 to 1990. He examined Richard M. Nixon for the Watergate investigation.
Raad Hashem Mohiaddin is professor of cardiovascular imaging at the National Heart and Lung Institute at Imperial College, London, and Royal Brompton Hospital. He is twice winner of the William S. Moore award of the International Society of Magnetic Resonance in Medicine the society's highest honor for medical investigators.
Alexander Sandor Nadas was a Hungarian-American pediatric cardiologist and Professor of Pediatrics at Harvard Medical School. He founded the cardiology program at Boston Children's Hospital, which was one of the early training programs in pediatric cardiology. Nadas authored an influential textbook, now known as Nadas' Pediatric Cardiology.
Catherine Annie Neill was a British pediatric cardiologist who spent the majority of her career at the Johns Hopkins Children's Center in Baltimore, where she worked alongside Helen B. Taussig. Her primary interest was congenital heart defects; she discovered one type of defect, scimitar syndrome, in 1960.
Johns Hopkins Children's Center (JHCC) is a nationally ranked, pediatric acute care children's teaching hospital located in Baltimore, Maryland, United States, adjacent to Johns Hopkins Hospital. The hospital has 196 pediatric beds and is affiliated with the Johns Hopkins School of Medicine. The hospital is the flagship pediatric member of Johns Hopkins Medicine and is one of two children's hospitals in the network. The hospital provides comprehensive pediatric specialties and subspecialties to infants, children, teens, and young adults aged 0–21 throughout Baltimore and the wider United States. Johns Hopkins Children's Center also sometimes treats adults who require pediatric care. Johns Hopkins Children's Center also features the only ACS verified Level 1 Pediatric Trauma Center in the state. The hospital is directly attached to Johns Hopkins Hospital and is situated near the Ronald McDonald House of Maryland.
Stella Van Praagh was a pediatric cardiologist and pathologist at Children's Hospital Boston. She was internationally known for her contributions to the pathology of congenital heart disease.
Harvey Feigenbaum is an American cardiologist known for his life-long work in the field of echocardiography. He wrote the first textbook on the subject in 1972, which is currently in its 8th edition, and has published over 300 articles. He has trained generations of cardiologists including many of the world's pioneers in the field through his numerous visitors, frequent workshops, annual courses in Indianapolis, Indiana beginning in 1968, the year when he started formal fellowship training He founded the field of cardiac sonography in 1965 and the American Society of Echocardiography in 1975. His seminal article on the diagnosis of pericardial effusions published in 1965 with his technique "brought echocardiography to the attention of thousands of practitioners".
