Cardiovascular System Flashcards
Congenital heart defects
Structural abnormalities caused by the failure of the heart to develop normally before birth
Congenital
Present at birth
Atherosclerosis
Hardening and narrowing of the arteries from the builup of cholesterol plaque on the interior walls of the arteries
Coronary artery disease (CAD)
Condition where the arterise that supply blood to the heart become narrowed or blocked
Ischemia
Condition where there is an insufficient supply of oxygen in the tissues due to restricted blood flow to a part of the body
Angina (angina pectoris)
Secere episodes of chest pain due to inadequate blood flow to the myocardium, or heart muscle
Myocardial Infarction
Heart attack caused by occlusion or blockage of one or more coronary arteries caused by plaque builup
Congestive heart failure (CHF)
Chronic condition in which the heart cannot pump out all of the blood it receives causing congestion of blood
Left-sided heart failure
Causes an accumulation of fluid in the lungs, called pulmonary edema
Right-sided heart failure
Causes fluid to build up throughout the rest of the body causing edema first in the feet and legs and then worsening to other parts of the body
Cardiomegaly
Abnormal enlargement of the heart as it tries to compensate for its decreased pumping ability
Carditis
Inflammation of the heart
Endocarditis
Inflammation of the endocardium, or inner lining of the heart. If the inflammation is causing by a bacteria, bacterial _____
Pericarditis
Inflammation of the pericardiual. Causes a fluid buildup in the pericardial sac which restricts movement of the heart and its abililty to pump blood to the body
Myocarditis
Inflammation of the heart muscle itself, or myocardium
Dilated cardiomyopathy
Disease of the heart muscle that causes the heart to become enlarged and to pump in a wealer fashion. Disease progression is slow and is often discovered only when the disease is advanced
Hypertrophic cardiomyopathy
Disease involves abnormal thickening of the heart muscle making it harder for the to pump
Restricitive cardiomyopathy
Type refers to the heart muscle bacoming stiff and less flexible, preventing expansion and filling with blood between heart contractions
Arrhythmia
Loss of normal rhythm of the heartbest. Can be a fatal event or it can be temporary
Asystole
Called flat line. Refers to a complete lack of electrical activity in the heart indicating no heart contraction and no blood pumping through the body
Cardiac arrest
Ebent in which the heart abruptly stops beating, preventing blood from being pumped through the body
Sudden cardiac death
Results when treatment of cardiac arrest is not provided within a few minutes
Heart block
Arrhythmia caused by
Bradycardia
Abnormally slow resting heart rate
