#cardiovascular_disease  a disease of the heart or blood vessels
  supertype:  disorder.state__upset  condition in which there is a disturbance of normal functioning; "the doctor prescribed some medicine for the disorder"; "everyone gets stomach upsets from time to time"
  subtype:  heart_disease__heartdisease__heart_condition__heartcondition__cardiopathy  a disease of the heart
     subtype:  angina_pectoris__angina  a heart condition marked by paroxysms of chest pain due to reduced oxygen to the heart
     subtype:  cardiac_arrhythmia__cardiacarrhythmia__arrhythmia  an abnormal rate of muscle contractions in the heart
        subtype:  flutter  abnormally rapid beating of the auricles of the heart (especially in a regular rhythm); can result in heart block
        subtype:  gallop_rhythm__cantering_rhythm__canteringrhythm  cardiac rhythm characterized by the presence of an extra sound; can indicate a heart abnormality
        subtype:  atrial_fibrillation  fibrillation of the muscles of the atria of the heart
        subtype:  bradycardia  abnormally slow heartbeat
        subtype:  heart_block__Adams-Stokes_syndrome__Stokes-Adams_syndrome__atrioventricular_block  recurrent sudden attacks of unconsciousness caused by impaired conduction of the impulse that regulates the heartbeat
        subtype:  premature_ventricular_contraction__prematureventricularcontraction__pvc  irregularity of cardiac rhythm; recurrent occurrences can be a precursor of ventricular fibrillation
        subtype:  tachycardia  abnormally rapid heartbeat (over 100 beats per minute)
        subtype:  ventricular_fibrillation__ventricularfibrillation  fibrillation of heart muscles resulting in interference with rhythmic contractions of the ventricles and possibly leading to cardiac arrest
     subtype:  cardiomyopathy__myocardiopathy  a disorder (usually of unknown origin) of the heart muscle (myocardium)
        subtype:  hypertrophic_cardiomyopathy  a disorder in which the heart muscle is so strong that it does not relax enough to fill with the heart with blood and so has reduced pumping ability
     subtype:  heart_failure__heartfailure__coronary_failure  inability of the heart to pump enough blood to sustain normal bodily functions
        subtype:  congestive_heart_failure  inability to pump enough blood to avoid congestion in the tissues
        subtype:  heart_attack__heartattack  a sudden severe instance of abnormal heart function
     subtype:  valvular_heart_disease  heart disease caused by stenosis of the cardiac valves and obstructed blood flow or caused by degeneration and blood regurgitation
        subtype:  aortic_stenosis  abnormal narrowing of the aortic valve
        subtype:  mitral_valve_prolapse  cardiopathy resulting from the mitral valve not regulating the flow of blood between the left atrium and left ventricle of the heart
        subtype:  mitral_stenosis__mitral_valve_stenosis  obstruction or narrowing of the mitral valve (as by scarring from rheumatic fever)
     subtype:  rheumatic_heart_disease__rheumaticheartdisease  heart disease caused by recurrent episodes of rheumatic fever; characterized by changes in the myocardium or scarring of the heart valves that reduce the power of the heart to pump blood
  subtype:  high_blood_pressure__hypertension  a common disorder in which blood pressure remains abnormally high (a reading of 140/90 mm Hg or greater)
     subtype:  essential_hypertension__essentialhypertension__hyperpiesis  persistent and pathological high blood pressure for which no specific cause can be found
     subtype:  malignant_hypertension__malignanthypertension  severe hypertension that runs a rapid course and damages the inner linings of the blood vessels and the heart and spleen and kidneys and brain; "malignant hypertension is the most lethal form of hypertension"
        subtype:  portal_hypertension  increase in blood pressure in the veins of the portal system caused by obstruction in the liver (often associated with alcoholic cirrhosis), causing enlargement of the spleen and collateral veins
     subtype:  secondary_hypertension__secondaryhypertension  hypertension that is secondary to another disease
     subtype:  white-coat_hypertension  temporary rise in blood pressure in the doctor's office
  subtype:  hypotension  abnormally low blood pressure
     subtype:  orthostatic_hypotension__postural_hypotension  low blood pressure occurring in some people when they stand up
  subtype:  aneurysm  a sac-like widening of an artery
     subtype:  aortic_aneurysm  an aneurysm of the aorta
     subtype:  cerebral_aneurysm  an aneurysm of the carotid artery
     subtype:  intracranial_aneurysm  an aneurysm of a cranial artery
     subtype:  ventricular_aneurysm__ventricularaneurysm  a localized dilation or protrusion on the wall of the left ventricle of the heart (occurring after a myocardial infarction)
  subtype:  circulatory_failure__circulatoryfailure  failure of the cardiovascular system to supply adequate amounts of blood to body tissues
