Four questions instead of one vague category

Heart health can feel like a pile of unrelated facts. A blood-pressure number lives in one portal, an echocardiogram in another, and the fact that stairs suddenly cost more may never enter the chart at all.

FLOW, BEAT, PUMP, and POWER give those facts a home. FLOW asks about delivery through blood vessels. BEAT asks about rhythm. PUMP asks about structure and mechanical function. POWER asks what the entire oxygen-delivery system can do when life raises the demand.

The parts overlap without becoming the same

Blood pressure can affect arteries and the heart muscle. Rhythm can affect output and exercise tolerance. Sleep, metabolism, lungs, blood, and muscle can influence capacity. The framework does not build walls between specialties; it prevents one answer from being mistaken for all answers.

That distinction matters when a woman is reassured about one part of the system but still has a changing story. It also matters when everything is reassuring and the right next step is simply to keep building capacity.

Use the map to choose one priority

The goal is not to create four simultaneous projects. Gather the baseline, choose the priority that matters now, decide what action fits, and name the evidence that would show whether it worked.

Risk is probability. Plaque is anatomy. Fitness is capacity. Knowing which one you are discussing makes the next conversation clearer.
