Chest Pain Flashcards
(35 cards)
immediate life-threatening causes of chest pain include
acute MI/acute CAS pulmonary embolism aortic dissection tension pneumothorax pericardial tamponade esophageal rupture
tearing pain
pain radiating between scapula from chest wall
aortic dissection
no symptoms or acute SOB, hyperesonnant areas over pneumothorax
tension pneumothorax
what sort of pt will have spontaneous pnemothorax?
vomitting or vomitting blood
what can mimick an MI
esophageal spasm
leading cause of death in US
Acute coronary syndrome/MI
angina pectoris
discomfort induced by exercise and relived by rest and or nitroglycerin
- due to ischemia of heart muscles
unstable angina
occurs with more frequent occurence of anginal episodes, longer lived episodes or more easily provoked angina.
Atypical or Prinzmetal angina
angina that occurs at rest
what is the main cause of angina pectoris?
ischemia of heart muscle and
atherosclerosis of coronary arteries feeding heart
what is the cardinal sign of decreased blood flow to the heart?
chest pain experienced as tightness around the chest and radiationg to the left arm and left angle of jaw
- diaphoresis, nausea, vomitting, SOB, anxiety, impending doom
ischemic heart disease includes
MI
angina pectoris
heart failure
high risk characteristics for ACS
pressure or squeezing
pain similar to prior AMI or angina
radiation to neck/shoulders, or left arm
associated dyspnea
MI in what areas of the heart could cause pulse to drop?
posterior aspect of L ventricle
anywhere in R ventricle
anywhere near apex
* all these areas can cause stimulation of vagus nerve which causes pulse to drop
unequal pulses
pain radiating to back
new murmur or aortic insufficiency
aortic dissection
Beck’s triad
cardiac tamponade
decreased breath sounds
pneumothorax
ST elevation MI 30%
STEMI
non-ST elevation MI 25%
Non-STEMI
unstable angina causes what % of MI
38%
plaque rupt\ptre and obstructrion occur when?
when lipid core is exposed to blood as it causes platelet aggregation
what is most sensitive test to rule out MI?
troponin
what does aspirin do?
platelet aggregation inhibitor
how is acute MI treated
oxygen
aspirin
sublingual nitroglycerin
