Endocardium is the thin inner lining of the heart chambers and heart valves. It is the surface that directly touches circulating blood. Clinicians refer to Endocardium when discussing heart valve disease, clots, infection, and certain rhythm problems. It is commonly evaluated with cardiac imaging such as echocardiography.

Myocardium is the muscular middle layer of the heart wall. It contracts to pump blood to the lungs and the rest of the body. Clinicians use the term when discussing heart function, damage, and healing. It is commonly referenced in imaging, ECG interpretation, and cardiac diagnoses.

A Syncope Clinic is a specialized outpatient service focused on evaluating fainting and near-fainting episodes. It brings structured, step-by-step assessment to symptoms that can have cardiac, vascular, neurologic, or reflex causes. It is commonly used in cardiology and electrophysiology practices, often in collaboration with emergency and primary care. Its goal is to clarify the cause of syncope and identify who may need closer monitoring or targeted testing.

A Pulmonary Hypertension Clinic is a specialized clinic focused on diagnosing and treating pulmonary hypertension (PH), a condition involving high blood pressure in the blood vessels of the lungs. It is commonly based in cardiology, pulmonology, or multidisciplinary heart–lung programs. People are usually referred when symptoms or tests suggest elevated pressure on the right side of the heart or within the pulmonary arteries.

Cardio-Oncology is a medical specialty focused on heart and blood vessel care in people with cancer. It helps prevent, detect, and manage cardiovascular problems related to cancer therapies and the cancer itself. It is commonly used in oncology clinics, cardiology clinics, and hospital settings where cancer treatment is delivered. It brings cardiology and oncology teams together to coordinate care.

Geriatric Cardiology is the part of cardiovascular medicine focused on heart and blood vessel care in older adults. It combines cardiology with principles of geriatrics, such as frailty, function, cognition, and medication safety. It is commonly used in outpatient clinics, hospital consultations, and pre-procedure planning for seniors. The goal is clear, individualized cardiovascular assessment and treatment planning that fits an older person’s overall health.

Sports Cardiology is a focused area of cardiovascular care for people who exercise regularly or compete in sports. It looks at how training and competition affect the heart and blood vessels. It also evaluates symptoms that happen with exercise, such as chest discomfort, shortness of breath, fainting, or palpitations. It is commonly used in athlete screening, “return-to-play” decisions, and performance-related cardiovascular testing.

Adult Congenital Heart Disease refers to heart and great-vessel conditions that are present from birth and persist into adulthood. It includes people with repaired, partially repaired, or unrepaired congenital (from birth) heart defects. It is commonly used as a clinical diagnosis category and as a specialized area of cardiology care. It helps clinicians describe anatomy, predict risks over time, and plan monitoring and interventions across adult life.

Pediatric Cardiology is the medical specialty focused on heart and blood vessel conditions in fetuses, infants, children, and adolescents. It includes diagnosing symptoms like murmurs, chest pain, palpitations, fainting, and shortness of breath. It also covers congenital (present at birth) heart disease, acquired heart disease, and heart rhythm problems. Pediatric Cardiology is commonly used in outpatient clinics, hospitals, cardiac imaging labs, and intensive care settings.

Cardiovascular Surgery is a medical specialty focused on operations on the heart and blood vessels. It is used to treat structural problems such as blocked arteries, diseased valves, and aortic disorders. It is commonly performed in hospitals with dedicated cardiac operating rooms and intensive care units. It often involves a team that includes cardiothoracic surgeons, anesthesiologists, cardiologists, and critical care clinicians.

Cardiac Surgery is a branch of medicine that treats diseases of the heart and nearby great vessels using operations. It can restore blood flow, repair or replace heart valves, correct structural problems, or support a failing heart. It is commonly used when symptoms, risk, or anatomy suggest that medicines or catheter-based procedures may not be enough. It is planned and performed by cardiothoracic surgeons in collaboration with cardiologists and anesthesia teams.

Cardiothoracic Surgery is the surgical care of diseases of the heart and the organs inside the chest. It most commonly includes heart surgery (cardiac surgery) and chest surgery (general thoracic surgery). It is used when a structural problem cannot be managed well with medicines alone. It is performed in hospitals with specialized operating rooms, intensive care units, and multidisciplinary teams.

Emergency Cardiology is the part of cardiovascular medicine focused on urgent heart and blood vessel problems. It covers time-sensitive evaluation and treatment when symptoms could reflect a dangerous cardiovascular condition. It is commonly used in emergency departments, ambulances, cardiac catheterization labs, and intensive care units. It often involves rapid testing, monitoring, and coordinated team-based care.

A Chest Pain Unit is a dedicated care pathway or location for evaluating chest pain that might be heart-related. It is most commonly used in emergency departments and hospital observation areas. It focuses on rapid testing, short-term monitoring, and structured decision-making. Its goal is to identify serious causes early while avoiding unnecessary hospitalization when appropriate.

Cardiac Critical Care is specialized hospital care for people with life-threatening or rapidly changing heart and blood vessel problems. It is typically delivered in a cardiac intensive care unit (CICU) or a cardiothoracic ICU (CTICU). The focus is close monitoring and rapid treatment when the heart, circulation, or rhythm becomes unstable. It often involves cardiologists, intensivists, nurses, pharmacists, respiratory therapists, and other specialists working as a team.

A Cardiac ICU is a hospital intensive care unit focused on life-threatening heart and circulation problems. It provides continuous monitoring and rapid treatment when a patient’s condition can change quickly. A Cardiac ICU is commonly found in hospitals that offer advanced cardiology and heart surgery care. It is also used after certain cardiac procedures when close observation is needed.

A Coronary Care Unit is a specialized hospital unit for people with serious heart conditions. It provides continuous heart monitoring and rapid treatment when the heart rhythm or circulation becomes unstable. It is commonly used in hospitals for emergencies such as heart attacks and dangerous arrhythmias. Care is delivered by a team trained in cardiac critical care.

Cardiac Rehabilitation is a structured program that helps people recover and regain function after a heart or vascular event. It typically combines supervised exercise, education, and risk-factor management. It is commonly used after heart attacks, heart procedures, or diagnosis of certain heart conditions. It is delivered by a multidisciplinary healthcare team in hospital, outpatient, or home-based settings.

A **Structural Heart Program** is a coordinated clinical service focused on diseases of the heart’s valves and other “structural” parts of the heart. It brings multiple specialists together to evaluate patients and plan procedures when needed. It is commonly used in hospitals and heart centers that offer advanced imaging and catheter-based or surgical heart procedures. It is designed to streamline evaluation, treatment selection, and follow-up for complex heart conditions.

A Heart Failure Program is a coordinated clinical service that evaluates and manages people with heart failure. It combines cardiology care with nursing, pharmacy, rehabilitation, and other support to improve follow-up and treatment consistency. It is commonly offered in hospitals, outpatient cardiology clinics, and specialized heart centers. It may also include remote monitoring and structured education for patients and caregivers.
