Welcome to critcard

Critical care cardiology lives at a peculiar seam. The pace is acute, the margins are tight, and the half-life of useful information at 3 a.m. is short. Most reference material is either too long to read on rounds or too thin to trust in a high-stakes call. critcard is an attempt to land somewhere useful in between.

What this is

A small, opinionated reference site with two surfaces:

• Notes — concise writeups on diagnosis, monitoring, hemodynamics, and management. Cited where it matters, brief by default.
• Apps — interactive calculators and decision aids built for the bedside. Risk scores, hemodynamic math, dosing helpers, and a few flowcharts.

If a topic can be communicated in three paragraphs and a table, it should be. If it needs a calculator, the calculator should fit on a phone screen and return an answer in fewer than five inputs.

Who it's for

Residents and fellows on cardiac critical care service. Hospitalists covering the unit overnight. Pharmacists and nurse practitioners triangulating a dose. Anyone who needs a cited answer faster than a textbook delivers one.

What to expect

The early releases will be intentionally narrow:

1. A small handful of high-yield risk calculators.
2. A few short writeups on common acute presentations — AHF, NSTEMI, cardiogenic shock.
3. A reference card or two for hemodynamic interpretation.

If you want something specific, the right move is to send a request. The site grows in the direction of what's actually used at the bedside.

A note on style

You'll notice the visual language leans toward bedside monitor more than consumer blog. That's deliberate. The aim is calm density: enough information on screen to be useful, none of the noise that makes you scroll through ads to find a number you needed twenty seconds ago.

Welcome aboard. More soon.
