Disorders & Pathologies of the Cardiovascular System Flashcards
What is Sickle Cell Disease?
This is a Genetic defect in the hemoglobin.
The RBC can break easier causing Anemia and blood clots.
What is Angina Pectoris?
This is pain related to MI.
The pain is local to Sternum, down the left arm and in to the neck.
What is MI?
This is also referred to as a “Heart attack”, they occur after arteries to the heart wall have been blocked for a long enough time for tissue death of the heart muscle to occur.
What is Hemophilia?
Inherited deficiency of clotting factors
bleeding spontaneously (nosebleeds, blood in urine, articular bleeding) or after minor trauma
subcutaneous & intramuscular hemorrhaging
pain
• Hemophilia A lacks factor VIII (males only) - most common
• Hemophilia B lacks factor IX (males only)
• Hemophilia C (males & females) - less severe because alternate clotting activator exists
• Treatment is transfusions of fresh plasma or concentrates of the missing clotting factor
What is Anemia?
It is reduced o2 carrying capacity and because of low RBC’s count.
What is Leukemia?
Red bone marrow cancers in which white blood cells multiply uncontrollably (affecting normal production on WBC, RBC, and platelets reducing the oxygen carrying capacity
Makes person more susceptible to infection and leads to abnormal clotting
Causes WBCs to spread to lymph nodes, spleen, and liver enlarging them
What is Atherosclerosis?
This is a condition of a hardening of the Arteries.
It occurs when fat, cholesterol and other substances build up in the arteries and form hard structures called plaques.
What are Cerebrovascular Diseases?
This refers to a group of conditions that affect the circulation of blood to the Brain.
What are Symptoms of Anemia
Includes:
Fatigue, cold intolerance & paleness.
What are the Symptoms of Leukemia?
Symptoms include: fatigue, intolerance to cold, pale skin, weight loss, fever, night sweats, excessive bleeding and recurrent infections
What are the charectoristics of Leukemia?
Acute – rapid onset
Chronic – symptoms take years to develop
Lymphoblastic –cells form lymphoid stem cells or lymphocytes
Myelogenous – myeloid stem cells or myeloblasts
What are the Symptoms of Atherocclerosis?
Does not show symptoms until blood flow slows or is blocked
If the arteries to the heart become narrow, blood flow to the heart can slow down or stop. This can cause chest pain (stable angina), shortness of breath, and other symptoms.
Narrowed or blocked arteries may also cause problems and symptoms in your intestines, kidneys, legs, and brain
What are the symptoms of Sickle cell disease?
This include:
Animea, shortness of breath, fatigue, paleness, fever, inflammation of the hands & feet, Frequent urination.
What are the types of Anemia?
All the types are:
Iron deficiency, Metabolic Anemia, Pernicious, Hemorrhagic, hemolytic, thalassemia, Aplastic.
How is Iron deficiency Anemia Caused?
lack of absorption or loss of iron, this is the most common type.
How is metabolic Anemia caused?
Inadequate B12or folic acid intake.
How is Pernicious Anemia Caused?
Insufficient hemopoiesis.
