Supply, pump, and rhythm

Coronary blood supply and ischemia

Conditions where the heart muscle does not receive enough oxygen-rich blood.

Coronary heart disease and ischemiaCoronary heart disease and ischemiaPlaque-narrowed coronary arteries can limit oxygen-rich blood reaching heart muscle.

Coronary blood flowAtherosclerotic plaqueLDL cholesterolTroponinECG / EKG

Pump reserve and pressure load

Conditions where the heart cannot pump enough, fill well, or faces sustained pressure load.

CHFHeart failure and pump reserveThe heart cannot pump enough oxygen-rich blood for the body’s needs, even though it has not stopped.

Rhythm and electrical control

Conditions where heartbeat timing or conduction becomes the main problem.

AFibAtrial fibrillation and rhythm lossAtrial fibrillation is a common treated arrhythmia where irregular upper-chamber rhythm changes clot and stroke context.

Structure and vascular load

Vascular and metabolic load

Blood pressure, cholesterol, vascular disease, and metabolic context that change cardiac risk.

High blood pressure and heart loadHigh blood pressure and heart loadSustained high blood pressure makes the heart work harder and can contribute to heart, stroke, kidney, and vessel problems.

Valves, structure, and heart muscle

Valve flow, chamber shape, and heart-muscle disorders that change cardiac function.

Cardiomyopathy and heart-muscle diseaseCardiomyopathy and heart-muscle diseaseHeart muscle can become thicker, stiffer, enlarged, or weak, changing pump and rhythm stability.
