Then inimitable @FiedlerAmy reminding us that cardiac surgeons have feelings too! 😂 And educating us on when to call the surgeon and consider a return to the OR in the middle of the night. Communication is key! @UCSFHospitals #critcarecards25 @SocietyOfCCC

Counterpoints!
🫀 End-organ hypoperfusion is seen with ‘normal’ macrohemodynamics
🫀CS mortality needs improvement
🫀Cap refill is easy & predictive
🫀Can augment microcirculation
🫀MORE personal, LESS protocol
#CritCareCards25 @SocietyOfCCC @CCCEnthusiasts @carlosalviar
#critcarecards25 @aaguirreMD the new gold standard for perfusion in cardiogenic shock… in my humble opinion of course
Congratulations to @DanbocMD on his pub! Food for thought in how we educate residents in thinking about heart failure and shock. doi.org/10.1016/j.cjco.2025.…

@ISHVnews @InovaHealth Heart Failure and Shock Symposium continues with an outstanding discussion on challenges in shock team activation and logistics - how do we do this with higher fidelity and less heterogeneity? @RanLeeMD @vbluml @ShashankSinhaMD

Last day of @HoustonShockHSS kicking off with discussions on the real world logistics of delivering shock care and the financial sustainability of shock programs - you can’t do shock well if you don’t review your outcomes and work towards iterative improvement.

Vigorous debate on how we staff the CICU. Dual boarded cardiologist/intensive care vs. Cardiology with ICU co management? @ShashankSinhaMD and @ElliottMillerMD engaging in some friendly fire @AndrewHigginsMD @jameshorowitzmd @RThachilMD @danielmarcosmd @SocietyOfCCC #hss25
