  "overview": [
    "Cardiogenic shock occurs when the heart's pumping function fails so severely that it cannot deliver adequate blood flow to meet the body's metabolic demands, most commonly following a large myocardial infarction but also from severe heart failure, myocarditis, or valve rupture. Unlike other shock states where fluids typically help, the failing heart in cardiogenic shock often cannot tolerate volume, making management fundamentally different and requiring careful hemodynamic titration.",
    "The pathophysiology is a vicious cycle: reduced cardiac output lowers coronary perfusion, which further impairs myocardial contractility, which further reduces cardiac output. Compensatory catecholamine release increases heart rate and vascular resistance, raising myocardial oxygen demand at the very moment supply is falling, accelerating the downward spiral unless interrupted.",
    "Nursing care requires continuous, often invasive, hemodynamic monitoring; precise titration of inotropes and vasopressors; and readiness to support mechanical circulatory assistance (intra-aortic balloon pump, ventricular assist devices) when pharmacologic support is insufficient. Mortality remains high, so early recognition and rapid, coordinated escalation of care are critical to any chance of survival."
