Cardiac

Question 1

what is coronary artery disease

Answer 1

• Narrowing or blockage of coronary arteries

Question 2

what is angina

Answer 2

• Chest pain

Question 3

what is stable vs unstable angina

Answer 3

• predicatable
• unpredicatable, no pattern

Question 4

What is myocardial infarction

Answer 4

• narrowing of coronary arteries
  = myocardial ischemia
  = hypoxia
  = myocardial necrosis
  = breakdown of sarcolemma
  = leakage of intracellular proteins

Question 5

myocytes undergo 3 ways

Answer 5

1. stunning (temp loss of contraction)
2. hibernation (stop contracting to stay alive)
3. remodeling (permanent loss of contractibility)

Question 6

What is arrythmia

Answer 6

• alternations in cardiac conduction

Question 7

atrial fibrillation

Answer 7

atrial walls quiver
- blood pools in atria
- blood clots
-embolism

Question 8

ventricular tachy cardia

Answer 8

• rapid ventricular contractions = increase HR

Question 9

ventricular fibrillation

Answer 9

• ventricles quiver
• no c.o
• defibrillation asap

Question 10

asystole

Answer 10

• no electrical activity

Question 11

heart failure

Answer 11

• cardiac dysfunction
• systolic failure (pumping failure)
• Diastolic failure (filling failure)

Question 12

Left heart failure

Answer 12

• pulmonary congestion and decrease CO
  = tissue ischemia
  = hypertension
  = impair gas exchange

Question 13

right heart failure

Answer 13

• systemic venous hypertension and decrease pulmonary c.o
• peripheral oedema
  = liver failure

Question 14

Left heart failure S+S

Answer 14

• pulmonary complications

Question 15

Right heart S+S

Answer 15

• liver failure
• oedema
