HOSA Pathophysiology: Heart, Blood
Vessels, and Lymphatic Questions and
Answers.
Coronary Artery Disease - Answer is a condition involving the arteries supplying the
mycardium (heart muscle). The arteries become narrowed by atherosclerotic deposits over time
causing ischemia (holding back blood flow) and eventually MI or heart attack.
Tachycardia - Answer Heartbeat is abnormally fast
Bradycardia - Answer Heartbeat that is abnormally slow
Angina Pectoris - Answer chest pain due to blood flow block ( ischemia ) during or shortly
after exertion, is the result of reduced oxygen supply to the myocardium ( muscle tissue of the
heart )
Myocardial infarction - Answer MI is the death of myocardial tissue that is caused by the
development of ischemia ( blood flow block ).
Cardiac arrest - Answer the sudden, unexpected cessation of cardiac activity.
Hypertensive heart disease - Answer is the result of chronically elevated pressure
throughout the vascular system.
Essential hypertension - Answer Essential or primary hypertension, or a condition of
abnormally high blood pressure in the arterial system, has an insidious onset, with the patient
exhibiting few, if any, symptoms until permanent damage has occurred.
Malignant Hypertension - Answer a life threatening condition, is a severe form of
hypertension
Congestive heart failure - Answer is an acute, or chronic inability of the heart to pump
enough blood throughout the body to meet the demands of homeostasis.
Cor Pulmonale - Answer aka right sided heart disease, results in enlargement of the right
ventricle as a sequela to primary lung disease.
