Cardiac Output
|
D002302 |
[The volume of BLOOD passing through the HEART per unit of time. It is usually expressed as liters (volume) per minute so as not to be confused with STROKE VOLUME (volume per beat).
] |
|
Cardiac Output, High
|
D016534 |
[A state of elevated cardiac output due to conditions of either increased hemodynamic demand or reduced cardiac oxygen output. These conditions may include ANEMIA; ARTERIOVENOUS FISTULA; THYROTOXICOSIS; PREGNANCY; EXERCISE; FEVER; and HYPOXIA. In time, compensatory changes of the heart can lead to pathological form of high cardiac output and eventual HEART FAILURE.

|
Cardiac Output, Low
|
D002303 |
[A state of subnormal or depressed cardiac output at rest or during stress. It is a characteristic of CARDIOVASCULAR DISEASES, including congenital, valvular, rheumatic, hypertensive, coronary, and cardiomyopathic. The serious form of low cardiac output is characterized by marked reduction in STROKE VOLUME, and systemic vasoconstriction resulting in cold, pale, and sometimes cyanotic extremities.

|
Cardiac Pacing, Artificial
|
D002304 |
[Regulation of the rate of contraction of the heart muscles by an artificial pacemaker.
] |
|
Cardiac Papillary Fibroelastoma
|
D000084122 |
[Primary tumors, predominantly of the CARDIAC VALVES, characterized by multiple papillary frond structures. Although histologically benign, they may result in complications (e.g., valve dysfunction, EMBOLISM; STROKE; and SUDDEN DEATH).
] |
|
Cardiac Rehabilitation
|
D000072038 |
[Restoration of functions to the maximum degree possible in a person or persons suffering from a CARDIOVASCULAR DISEASE. It also includes cardiac conditioning and SECONDARY PREVENTION in patients with elevated cardiovascular risk profile.
] |
|
Cardiac Resynchronization Therapy
|
D058406 |
[The restoration of the sequential order of contraction and relaxation of the HEART ATRIA and HEART VENTRICLES by atrio-biventricular pacing.
, Electrical stimulation of the heart by artificial pacemaker leads placed at sites in the RIGHT ATRIUM and both HEART VENTRICLES to treat various cardiac conduction disturbances which interfere with the timing of contraction of the ventricles.
] |
|
Cardiac Resynchronization Therapy Devices
|
D058409 |
[Artificial pacemakers with implantable leads to be placed in the RIGHT ATRIUM and both HEART VENTRICLES. They are used to treat various cardiac conduction disturbances which interfere with the timing of contraction of the ventricles.
, Types of artificial pacemakers with implantable leads to be placed at multiple intracardial sites. They are used to treat various cardiac conduction disturbances which interfere with the timing of contraction of the ventricles. They may or may not include defibrillating electrodes (IMPLANTABLE DEFIBRILLATORS) as well.

|
Cardiac Surgical Procedures
|
D006348 |
[Surgery performed on the heart.
] |
|
Cardiac Tamponade
|
D002305 |
[Compression of the heart by accumulated fluid (PERICARDIAL EFFUSION) or blood (HEMOPERICARDIUM) in the PERICARDIUM surrounding the heart. The affected cardiac functions and CARDIAC OUTPUT can range from minimal to total hemodynamic collapse.
] |
|
Cardiac Valve Annuloplasty
|
D058385 |
[A type of heart valve surgery that involves the repair, replacement, or reconstruction of the annuli of HEART VALVES. It includes shortening the circumference of the annulus to improve valve closing capacity and reinforcing the annulus as a step in more complex valve repairs.
] |
|
Cardiac Volume
|
D002306 |
[The volume of the HEART, usually relating to the volume of BLOOD contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is STROKE VOLUME.
] |
|
Cardiac-Gated Imaging Techniques
|
D055424 |
[Timing the acquisition of imaging data to specific points in the cardiac cycle to minimize image blurring and other motion artifacts.
] |
|
Cardiac-Gated Single-Photon Emission Computer-Assisted Tomography
|
D055426 |
[Tomography using single-photon emitting RADIONUCLIDES to create images that are captured in times corresponding to various points in the cardiac cycle.
] |
|
Cardiidae
|
D049873 |
[A family of bivalve MOLLUSKS with heart-shaped shells, commonly known as cockles. Unlike most BIVALVES, cockles are hermaphroditic.
] |
|
Cardio Ankle Vascular Index
|
D000080308 |
[An index of ARTERIAL STIFFNESS obtained from PULSE WAVE VELOCITY measurements between the heart and the ankle.
] |
|
Cardio-Renal Syndrome
|
D059347 |
[Condition where a primary dysfunction of either heart or kidney results in failure of the other organ (e.g., HEART FAILURE with worsening RENAL INSUFFICIENCY).
] |
|
Cardiobacteriaceae
|
D044065 |
[A family of gram-negative, mostly aerobic bacteria, in the order Cardiobacteriales. There are three genera: CARDIOBACTERIUM; DICHELOBACTER; and Suttonella.
] |
|
Cardiobacterium
|
D044066 |
[A genus of gram-negative, facultatively anaerobic bacteria in the family CARDIOBACTERIACEAE. It is found in the nasal flora of humans and causes ENDOCARDITIS.
] |
|
Cardiography, Impedance
|
D002307 |
[A type of impedance plethysmography in which bioelectrical impedance is measured between electrodes positioned around the neck and around the lower thorax. It is used principally to calculate stroke volume and cardiac volume, but it is also related to myocardial contractility, thoracic fluid content, and circulation to the extremities.
