Transcript Etiology

Diseases and Disorders of the
Cardiovascular System
Endocarditis
Etiology
 Inflammatory process
or infection
Congestive Heart Failure
Etiology
 Pulmonary hypertension,
high blood pressure,
polycythemia, increased
work of the heart, MI,
valvular disease, cardiac
infections
Murmur
Etiology
 A result of blood
leaking backward due
to a faulty heart valve
or a narrowed valve
opening
Aneurysm
Etiology
 Genetic
predisposition,
hypertension,
trauma,
atherosclerosis,
tertiary syphilis
Angina
Etiology
 Ischemia of the
myocardium, as a
result of poor blood
perfusion of heart
tissue
Arteriosclerosis
Etiology
 “Hardening of the
arteries” due to age,
materials deposited in
the inner walls of the
arteries, or other
degenerative
conditions
Atherosclerosis
Etiology
 The most common form
of arteriosclerosis -caused
by the buildup of a yellow,
fat-like substance called
plaque. Caused by
heredity, improper diet,
smoking, sedentary life
style, stress
Hypertension
Etiology
 Heredity, diet (high fat and
salt intake), age (increases
the older you are), obesity,
smoking, stress, decreasing
flexibility of the blood
vessels
Myocardial Infarction
Etiology
 Conditions / situations that
lead to a decreased blood
flow to the heart tissue that
leads to ischemia and
necrosis
 Myocardial Infarction-

Peripheral Vascular Disease
Etiology
 Atherosclerosis,
plaque buildup, in
arteries with a
progressive narrowing
of the lumen, diabetes
Fibrillation
Etiology
 Acute MI, electrolyte
imbalances,
hypertrophy,
electrical shock
 Atrial Fibrillation Me Being
Cardioverted YouTube
Heart Block
Etiology
 Scar tissue in heart
muscle may affect the
smooth flow of the
electrical impulse
Palpitation
Etiology
 Structural abnormalities,
irritation /inflammation /
trauma to heart tissue,
drugs, stress, various
diseases of other body
systems
Anemia
 Cancer, radiation, or
chemotherapy which alters
bone marrow; too little
amino acids, folic acid,
iron, or vitamins B6 or
B12; production of
defective erythrocytes;
excessive blood loss
Hyperlipidemia
Etiology
 An increasing problem in
which there is an
excessive amount of fatty
substances in the blood
which include
cholesterol, triglycerides
and fatty acids
Leukemia
Etiology
 Unknown; possibly,
inherited factors,
radiation,viral causes
