Congratulations to @LeilaHaghighat on her insightful analysis!!!

[Jason N. Katz @JasonKatzMD]

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 @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. https://t.co/9jx1Fx1TMg

[Andrew Higgins @AndrewHigginsMD]

@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

[Andrew Higgins @AndrewHigginsMD]

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.

[Ran Lee, MD, FACC @RanLeeMD]

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

[Ann Gage @AnnGageMD]

Captivating discussion on Training the Critical Care Cardiologist! Extra enjoyable to watch @RanLeeMD debate his Program Director @NealChaisson. @SocietyOfCCC @CCFcards @CCF_PCCM @AndrewHigginsMD @ACCinTouch @carlosalviar @AmandaGarfinkel @seanvandiepen @APCCMPD
