  • shift of the aorta to the right- aorta overrides the interventricular septum, oxygen poor blood passes from the right ventricle to the aorta
  • hypertrophy of the right ventricle- myocardium works harder to pump blood through a narrowed pulmonary artery
106
Q

108
Q

systolic congestive heart failure (CHF)

A
  • left ventricular dysfunction results in a low ejection fraction (the amount of blood that leaves the left ventricle)
  • less blood is pumped from the heart
109
Q

diastolic congestive heart failure (CHF)

A
  • heart can contract normally but is stiff when relaxed or filling with blood
  • fluid backs up in the lungs and other parts of body
  • cause is hypertension
110
Q

angiotensin-converting enzyme (ACE) inhibitors (type 1), beta blockers, spironolactone, digoxin

A

increases excretion of water and sodium by the kidney

  • pumps blood out of the heart to the body
  • used while waiting for heart transplant or if it isnt an option
112
Q

coronary artery disease (CAD)

A

-disease of the arteries surrounding the heart
-coronary arteries arise from the aorta
-usually a results of atherosclerosis (fatty compound deposition on inner lining of coronary arteries)
-

113
Q

thrombotic occulsion

A

-blocking of the coronary artery by a clot

-

114
Q

ischemia

A

decreased blood flow

115
Q

infarct

A
  • area of dead myocardial tissue
  • replaced by scar tissue
  • caused by thrombotic occlusion -> ischemia -> necrosis
116
Q

myocardial infarction

A

-atherosclerosis (fatty compound on inner lining of artery) -> thrombotic occlusion (clot) -> ischemia (decreased blood flow) -> necrosis -> infarction

117
Q

acute coronary syndromes (ACSs)

A

conditions caused by myocardial ischemia

  • unstable angina (chest pain or chest pain of increasing frequency)
  • myocardial infarction
  • consequence of plaque rupture in coronary arteries
  • treat with stents, balloon catheter, anticoagulants, antiplatelet agents
118
Q

nitroglycerin

A
  • treats angina
  • taken sublingually (under tongue)
  • nitrate- vasodilator that increases coronary blood flow and lower BP
119

calcium into muscle cells lining vessels.

120
Q

statin
