SD D2 Flashcards
Formula of ABI
LE SBP/UE SBP
Special Test to determine the latency of the radial and ulnar arteries.
Allen Test
Test wherein you examine color changes in skin during elevation followed by dependency (seated hanging position).
Rubor of Dependency
Exercise induced pain in the leg which is absent at rest.
Intermittent Claudication
This test determines the competence of the greater saphenous vein.
Percussion Test
This test checks the competence of the communication veins and saphenous vein.
Trendelenburg test or Retrograde filling test
LE is elevated and a tourniquet is placed on the thigh, leave for 1 min. Then check for venous distention before removing the tourniquet.
What is this special test and + sign
Trendelenburg test or Retrograde filling test
10 sec - valvular valve incompetence
This is a controversial special test because it promotes thrombus dislodgment.
Homans Sign
Disease wherein there is narrowing of the lumen of the coronary artery.
CAD - coronary artery disease
Main cause of CAD
Atherosclerosis
Three main cause of atherosclerosis.
- Plaque Formation - fats, calcium and fibrous scar
2, Thrombus - blood clot - Spasm - sudden constriction of the arteries (Reynauds Dse)
Two component of hyperlipidemia.
Hypercholeterolemia + hyepertriglyceridemia
with decreased HDL
Meds for hyperlipidemia
Statin drugs
Examples of Statin drugs
Lipitor, Zocor, Mevacor
Severe side-effect of statin drugs
Rhabdomyolysis
SSx of rhabdomyolysis
Dark Urine and mm weakness
Give the 6 modifiable risk factors of CAD
- Hyperlipidemia
- Hypertension
- Smoking
- Diet
- Physical Inactivity
- Stress
Give the 5 Non-Modifiable risk factors of CAD
- Age
- Sex (Male>Female)
- Race (African)
- Family History
- Post Menopause (decreased estrogen)
Other name of resting angina
angina decubitus
Other name of unstable angina
Crescendo angina
Preinfarction angina
Progressive angina
Angina caused by dreams
Nocturnal Angina
Common condition with nocturnal angina
CHF
Other name of Prinzmetal Angina
Variant Angina
What time does Prinzmetal angina often occur.
Morning, due to increase in blood clot mechanism.
Referred pain areas in angina pectoris (5)
- L upper rib cage
- L jaw
- L upper cervical area
- L ulnar nerve distribution
- L shoulder
Most common cause of Myocardial Infarction
Thrombosis
This is caused by sudden coronary perfusion or sudden decrease in blood to the heart
Myocardial infarction
Ssx of MI
- Sudden loss of responsiveness
- No Normal breathing
- No signs of circulation
What time is MI most common
Morning
Earliest Enzyme present in an MI
CKMB
This is the sole marker for MI, this enzyme stays elevated the longest in MI.
Cardiac Troponin
Give the three zones of infarction in Mi.
- Zone of Ischemia
- Zone of Injury
- Zone of Infarction
Zone of MI: Intact function deprived O2, T wave inversion with ST depression.
Zone of Ischemia
Zones of MI: Reversible with treatment, ST segment elevation
Zone of Injury
Zones of MI: Total deprevation of O2, necrosis, 75% dead (transmural MI) 25% still alive, ST segment elevation with Shrap Q wave
Zone of Infarction
ECG Changes: ST segment depression and T wave inversion
Zone of Ischemia
