What Now?
Treat for CHF?
Biopsy heart muscle?
Anticoagulate?
Anticoagulate and take to the cath lab?
Send home?

You get some labs and an echo

Admit for CHF management?
Take to the cath lab?
Something else?

LHC
LM: No significant disease LAD: 100% occluded proximally D1-large caliber with 100% occlusion proximally RCA: 100% distally with large amounts of thrombus. RCA supplies collaterals to the LAD. LCx: mid 50-60% lesion
PCI:
L sided Intraaortic balloon pump was done. Aspiration thrombectomy and 2.75x18mm Integrity BMS was done in distal RCA LAD PCI with 2.5x26 Integrity BMS

Killip classification- acute myocardial infarction
First published in 1967, this system focuses on physical examination and the development of heart failure to predict risk as described below:
Class I: No evidence of heart failure (mortality 6%)
Class II: Findings of mild to moderate heart failure (S3 gallop, rales < half-way up lung fields or elevated jugular venous pressure (mortality 17%)
Class III: Pulmonary edema (mortality 38%)
Class IV: Cardiogenic shock defined as systolic blood pressure < 90 and signs of hypoperfusion such as oliguria, cyanosis, and sweating. (mortality 67%)

Learning points - Cardiooncology
Cardiotoxicity from both: Radiation + chemotherapy.
Types
Type I: Irreversible injury (eg. Anthracyclines)
Type II: reversible dysfunction (eg. Herceptin)
Radiation-induced cardiotoxicity potentiates any damage caused by chemotherapy.
