Advanced hemodynamics.
Bedside speed.
Earlier referral.

ML4HF™ synthesizes complex invasive hemodynamic data into clear classifications, predicted trajectories, and referral-ready clinical snapshots — so every clinician at the bedside or in the cath lab can act earlier, with confidence.

The problem

The data is there.
The synthesis isn't.

Modern cardiac catheterization produces dense, sophisticated hemodynamic data — pressure-volume mechanics, energetic reserve, ventricular-arterial coupling. Most of it goes unused because most clinicians don't have time to compute it by hand.

So patients get staged on what's quick: blood pressure, cardiac output, filling pressures. The nuance — and the earlier referral that nuance enables — gets lost.

ML4HF™ closes that gap. It does the hard math behind the scenes and returns the answer in the language clinicians already use, in time for it to change the decision.

How it changes the bedside

Four shifts.
One synthesis.

Advanced synthesis

Pressure-volume mechanics, energetic reserve, ventricular-arterial coupling — computed in the background, returned in the staging language clinicians already use.

Targets you can act on

From the values you already have at the bedside or in the cath lab. No new monitoring. No extra steps.

Trajectories that hold

Trained on thousands of advanced HF cases. Refined continuously with every de-identified case clinicians contribute.

Earlier referrals

Energetic indices move before classical staging catches decline. Refer when it still matters — with a snapshot the receiving team can act on.

The product

Bedside hemodynamics → clinical trajectory, in seconds.

Enter the values you already have. ML4HF™ reconstructs the patient-specific pressure-volume loop, computes the full panel of energetic indices, renders Stevenson, SCAI, and ACC/AHA staging — and pairs them with a phenotype-driven management pathway — in a single screen.

  • Simplified or Classical home — pick the interface that matches your workflow.
  • Shareable referral card — de-identified case summary for peer review or quick AirDrop to a colleague.
  • Two-page referral PDF — branded clinical letterhead with assessment, management considerations, and escalation triggers.
  • Simulated therapy — model the response to afterload reduction, diuresis, inotropes, or mechanical support before you commit.
  • Longitudinal trajectory — track the patient across episodes; see whether the energetic phenotype is improving or worsening.
The dataset

Built on the population that needs it most.

ML4HF™'s predictive engine is trained on a large cohort of patients with advanced and end-stage heart failure — the population in which accurate trajectory information is the difference between timely referral and a missed window. The model learns continuously from every de-identified case clinicians contribute, so accuracy refines in step with the field.

  • Trained on thousands of advanced HF / SCAI Stage C–E cases
  • Continuous learning loop with de-identified clinician contributions
  • Outcome endpoint: 1-year composite — death, LVAD, or transplant
  • Methodologically aligned with the Grinstein 2024 energetic-tipping-point framework
  • IRB-approved retrospective cohorts; no patient identifiers leave the device
The outcome that matters

The fastest win in advanced HF isn't a new drug.
It's an earlier referral.

Most cardiogenic shock and end-stage HF patients arrive at advanced HF programs later than the data supports — sometimes by days, sometimes by weeks. The cost is measurable in mortality, LVAD eligibility, and transplant candidacy.

Energetic indices — contractile reserve, ventricular-arterial coupling, pulmonary arterial pulsatility — move before classical staging captures decline. ML4HF™ surfaces those changes the moment your hemodynamic data is in.

And when it's time to refer, the receiving team gets a phenotype, a trajectory, and a management pathway — not a fax. Less back-and-forth, less time lost, more options preserved.

For programs

A shared layer for your HF, MCS, or CCM team.

When your fellows, attendings, and APPs all use ML4HF™, every case is computed the same way, attributed correctly, and surfaced to the team in a shared library. The phenotype-driven referral pathway makes intake faster and decision-making more consistent across the program.

  • Shared case library, scoped to your program
  • Admin dashboard with usage + per-clinician attribution
  • Role-based visibility for teaching, QA, and M&M
  • SSO via Google Workspace or Microsoft 365

Methodology

Transparent by design.

A two-stage pipeline: a patient-specific pressure-volume reconstruction that yields the energetic indices, then an ML predictor trained on annotated advanced-HF outcomes that returns a 1-year composite event-rate estimate with an uncertainty band. The receiving clinician sees both the synthesis and the underlying physiology — never a black box.

Built clinician-to-clinician

For the moments when earlier becomes everything.

ML4HF™ is built by the clinicians who work between bedside hemodynamics and the decisions that follow. The advanced cardiovascular physiology under the hood — pressure-volume mechanics, energetic reserve, trajectory modeling — exists because we needed it ourselves. Every feature serves a single goal: getting the right patient to the right program earlier, with better information in hand.
