Cardiac Flashcards
1
Q
Stable Angina
A
- Most common symptom: chest pain the occurs behind the breastbone or slightly to the left
- begins slowly and gets worse over a few minutes before going away
- usually occurs with exercise, walking up stairs
2
Q
Unstable Angina
A
- sudden chest pain that gets worse over time, lasts longer than 15-20 minutes
- associated with SOB drop in BP
- occurs without cause
- doesn’t respond well to nitroglycerine
3
Q
Variant (Prinzmetal’s angina)
A
- coronary artery spasm
- sudden narrowing of one of the coronary arteries.
- chest pain may occur at same time every day, usually between midnight and 8AM
- not usually with exercise
4
Q
Acute mitral valve prolapse (regurgitation)
A
- one or both mitral valve leaflets ruptures suddenly, blood rushes to the left ventricle
5
Q
Pericarditis
A
- inflammation of the pericardium caused by a virus, bacteria, uremia, lupus or neoplasm, which causes chest pain

10
Q
Pneumothorax
A
Air in pleural cavity collapses the lung
11
Q
Mediastinal emphysema
A
- free air in the mediastinum which makes chest tightness and dyspnea

24
Q
How to differentiate pulmonary v. cardiac dyspnea?
A
Pulmonary:
- dyspnea asso. with cough, sputum, COPD
- expectoration relieves dyspnea
- gradual onset: COPD
- abrupt onset: pulmonary emboli, pneumothorax
Cardiac:
- relief with sitting up
- develops over hours or days
25
Paroxysmal supraventricular tachycardia
Palpitations with an abrupt onset, atria rate is higher than the ventricles
- tx: ablation of cells with increased rate
26
Neurally mediated syncope (vasovagal)
- mediated by emotional stress, orthostatic stress
- situation due to coughing, sneeze, defecation, visceral pain, micturition (urination), post micturition, post exercise, post-parandial
27
Cardiovascular causes of syncope
- Arrhythmias, bradycardia, tachycardia
- cardiac outflow obstruction
- aortic stenosis
- mitral valve prolapse
- carotid sinus syncope: hypersensitivity from shaving or tight collar
- hypovolemia
28
Edema
- excess accumulation of fluid in connective tissue's interstitial space
- usually gradual, develops in legs/ankles, worse in evening
- can be pitting (1+, 2+, 3+)
- Most common cause: CHF
29
Hemoptysis
- coughing up blood
- often a sign of pulmonary disease
- if cause is mitral valve stenosis: increased venous congestion will cause ruptured blood vessels or pulmonary infarct
30
Central cyanosis
a drop in the pulmonary venous saturation, due to arterial unsaturation, the aortic blood carries reduced hemoglobin
31
Peripheral cyanosis
normal systemic arterial saturation, but decrease flow through capillaries from decreased cardiac output
