ARGEN SHOCK: Mortality related to the use of Swan Ganz and to the hemodynamic pattern found in patients with AMICS

The Swan Ganz Catheter (SGC) allows us to diagnose different types of cardiogenic shock (CS). 1) Determine the frequency of use of SGC, 2) Analyze the clinical characteristics and mortality according to its use and 3) Analyze the prevalence, clinical characteristics and mortality according to the type of Shock. The 114 patients (p) from the ARGEN SHOCK registry were analyzed. A “classic” pattern was defined as PCP > 15 mm Hg, CI 1,200 dynes × sec × cm-5. A “vasoplegic/mixed” pattern was defined when p did not meet the classic definition. CS due to right ventricle (RV) was excluded. : SGC was used in 35 % (n:37). There were no differences in clinical characteristics according to SGC use, but those with SGC were more likely to receive dobutamine, levosimendan, and intra aortic balloon pump (IABP). Mortality was similar (59.4 % vs 61.3 %). The pattern was “classic” in 70.2 %. There were no differences in clinical characteristics according to the type of pattern or the drugs used. Mortality was 54 % in patients with the classic pattern and 73 % with the mixed/vasoplegic pattern, but the difference did not reach statistical significance (p:0.23). SGC is used in one third of patients with CS. Its use does not imply differences in the drugs used or in mortality. Most patients have a classic hemodynamic pattern. There are no differences in mortality or in the type of vasoactive agents used according to the CS pattern found.
