Cardiomyopathy is a group of primary diseases of the heart muscle. Early on there may be few or no symptoms. As the disease worsens, shortness of breath, feeling tired, and swelling of the legs may occur, due to the onset of heart failure. An irregular heart beat and fainting may occur. Those affected are at an increased risk of sudden cardiac death.
Cardiovascular disease (CVD) is any disease involving the heart or blood vessels. CVDs constitute a class of diseases that includes: coronary artery diseases, heart failure, hypertensive heart disease, rheumatic heart disease, cardiomyopathy, arrhythmia, congenital heart disease, valvular heart disease, carditis, aortic aneurysms, peripheral artery disease, thromboembolic disease, and venous thrombosis.
Quinidine is a class IA antiarrhythmic agent used to treat heart rhythm disturbances. It is a diastereomer of antimalarial agent quinine, originally derived from the bark of the cinchona tree. The drug causes increased action potential duration, as well as a prolonged QT interval. As of 2019, its IV formulation is no longer being manufactured for use in the United States.
Mitral stenosis is a valvular heart disease characterized by the narrowing of the opening of the mitral valve of the heart. It is almost always caused by rheumatic valvular heart disease. Normally, the mitral valve is about 5 cm2 during diastole. Any decrease in area below 2 cm2 causes mitral stenosis. Early diagnosis of mitral stenosis in pregnancy is very important as the heart cannot tolerate increased cardiac output demand as in the case of exercise and pregnancy. Atrial fibrillation is a common complication of resulting left atrial enlargement, which can lead to systemic thromboembolic complications such as stroke.
The QT interval is a measurement made on an electrocardiogram used to assess some of the electrical properties of the heart. It is calculated as the time from the start of the Q wave to the end of the T wave, and approximates to the time taken from when the cardiac ventricles start to contract to when they finish relaxing. An abnormally long or abnormally short QT interval is associated with an increased risk of developing abnormal heart rhythms and sudden cardiac death. Abnormalities in the QT interval can be caused by genetic conditions such as long QT syndrome, by certain medications such as sotalol or pitolisant, by disturbances in the concentrations of certain salts within the blood such as hypokalaemia, or by hormonal imbalances such as hypothyroidism.
Cardiomegaly is a medical condition in which the heart becomes enlarged. It is more commonly referred to simply as "having an enlarged heart". It is usually the result of underlying conditions that make the heart work harder, such as obesity, heart valve disease, high blood pressure (hypertension), and coronary artery disease. Cardiomyopathy is also associated with cardiomegaly.
Da Costa's syndrome is a psychiatric syndrome which presents a set of symptoms similar to those of heart disease. These include fatigue upon exertion, shortness of breath, palpitations, sweating, and chest pain.
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 liturature.
Left atrial enlargement (LAE) or left atrial dilation refers to enlargement of the left atrium (LA) of the heart, and is a form of cardiomegaly.
Annals of Cardiac Anaesthesia is a quarterly peer-reviewed open-access medical journal published by Medknow Publications on behalf of the Indian Association of Cardiovascular Thoracic Anaesthesiologists. It covers anaesthesia as related to cardiology and was established in 1998. The editor-in-chief is Prabhat Tewari, who succeeded Poonam Malhotra Kapoor in 2018. Kapoor caused controversy when she published an editorial touting the accomplishments of the journal. Although Kapoor published a correction, her successor accused her of having "glorified" her contributions, "undermining the efforts of the past editors" of the journal, and the editorial was subsequently retracted.
Himmatrao Saluba Bawaskar is an Indian physician from Mahad, Maharashtra. He is known for his research on treatment for scorpion stings. Much of his work has been published in the British medical journal The Lancet. He has also conducted research in the fields of snake bites, cardiovascular diseases, and hypothyroidism.
QRISK3 is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial fibrillation, diabetes mellitus, and antihypertensive treatment.
Walter Somerville CBE (1913–2005) was an Irish cardiologist who played a leading role in heart surgery at London's Middlesex and Harefield hospitals.
The British Cardiovascular Society (BCS) is a United Kingdom-wide health organisation based in London. It aims to represent all healthcare professionals working in the field of cardiology, set standards for prevention, diagnosis, and clinical care, and communicate those standards to the community and the patients through training, education and public outreach.
Sir William Errington Hume was a British physician and cardiologist.
John Crighton Bramwell (1889–1976) was a British cardiologist, professor of medicine, and one of the founders of cardiology as a specialist subject in the UK.
Brigadier Davis Evan Bedford (1898–1978) was a British physician and cardiologist.
John Maurice Hardman Campbell (1891–1973) was a British physician, cardiologist, and medical journal editor.
John Parsons Shillingford was a British physician and cardiologist, known as a pioneer of the introduction of coronary care units in the United Kingdom in the 1960s.
Riaz Haider is an American physician, cardiologist, author, and medical educator. He is best known for his work and research in the diagnostic cardiac ultrasound, heart pacemakers, exercise stress testing, and heart catheterization. He is the former President of the American Heart Association Nation's Capital Affiliate, and served as a Clinical Professor of Medicine at the George Washington University School of Medicine & Health Sciences from 1984 - 2011. He is an elected Fellow of the American College of Physicians, the American College of Cardiology, and the Royal College of Physicians. He retired in 2011 and currently resides in Potomac, Maryland.
