If structure should beat improvisation in heart failure care, repost.

[Marc Atzenhoefer, MD @AtzenhoeferM]

Heart failure patients have had pressure sensors in their lungs for a decade. Nothing was ever wrong with the device.

The problem is utilization - what the clinic does what the number varies wildly by provider, day, and institution.

SMART-HF fixes that. 👨‍🔧

[Marc Atzenhoefer, MD @AtzenhoeferM]

Those targets aren't arbitrary. Two large analyzes independently tie them to survival - reaching target = HR 0.72; a greater than 2 mmHg drop ~ 15% lower 2-yr mortality.

SMART-HF is the missing instruction manual for a tool thousands of clinics already deploy.

[Marc Atzenhoefer, MD @AtzenhoeferM]

The comparison that matters: among patients who started with high pressures, SMART-HF got roughly twice as many to a survival-linked target as real-world Medicare management -- 47% vs 24%.

Mean drop -3.3 mmHg ~double real-world care.

[Marc Atzenhoefer, MD @AtzenhoeferM]

37-patient community cohort.

Mean PA diastolic pressure fell 18.3 -> 16.1 mmHg at 90 days and 18.8 -> 15.5 mmHg at 6 months (both p< 0.001).

And the effect got bigger at 6-months, not smaller. The structure keeps working past the early post implant window.

In a recent @Cardiacwire interview, general #Cardiologist Dr. @AtzenhoeferM shares how our CardioMEMS HF System helps him proactively monitor PA pressures for his patients.

Traditional #HeartFailure management reacts to symptoms – #CardioMEMS helps change that.

Some things are worth waiting for...like my #1st #Indycar event where patience allowed me to enjoy it with 2/4 #loves of my life (the #Z stayed home)

Do NOT wait for #modern #cardiac #care. #Precision #heartfailure #management guided by #hemodynamics is here, and my 4th love

I have learned so much from Dr Tajik - thrilled to share our editorial on cardiac amyloidosis. @AJamilTajik @AllaqabanSuhail @renujain19 @PatrycjaGalazka @fuadfehmi

Entrenched practice patterns. Beware usual heart failure metrics in this population. Incorporating weights, symptoms, and exam findings into decision making complicates management, increases hospitalizations, and blunts the advantages afforded by implantable PA pressure sensors.

Heart failure patients transmitting remote pulmonary artery pressures fare better when strictly managed by hemodynamic algorithm. Routine care guided by algorithm ensures hemodynamic triggers for intervention while simultaneously curbing
