PCI
Cardio 3
| Question | Answer |
|---|---|
| difference between unstable angina and MI | myonecrosis |
| site w/lowest risk of bleeding | radial A |
| most common PCI site | femoral A |
| used to define plaque morphology | IVUA |
| used to measure pressure difference | FFR |
| used to define vessel wall contours | OCT |
| method of restenosis common with bare metal stents | neointimal hyperplasia |
| need ASA for life and clopidogrel for at least 1 month | bare metal stents |
| need ASA for life and clopidogrel for at least 1 year | drug eluding stents |
| takes longer for scar to form over stent | drug eluding stents |
| local hematoma | direct pressure on hematoma and give IV fluids |
| indicated by bradycardia or tachycardia w/back pain and hypotension | retroperitoneal hematoma |
| retroperitoneal hematoma | manual compression of puncture site, stop anticoagulants, and give IV fluids/transfusion |
| not stopped w/retroperitoneal hematoma | antiplatelets |
| pseudoaneurysm | manual compression or thrombin injection |
| sicker pt, heart failure, poor renal function, more dye used | higher risk for acute renal failure |
| acute renal failure | HYRDATE |
| blue toe syndrome | aggressive ASA |
| no driving | within 48 hrs |
| monitor vitals, groin, renal function, and CBC | within 24 hrs |
| MI goals for PCI | alleviate sx, dec MI size, dec mortality |
| angina goals for PCI | alleviate sx |
| evaluated using PCI | CHF, valvular heart disease, congenital heart disease |
| type(s) of angina that indicates PCI | stable |
| type(s) of coronary syn's that indicate PCI | acute (STEMI and NSTEMI) |
| type(s) of chest pain that indicates PCI | nonspecific, with SOB |
