  • • Inadequate tissue perfusion due to heart pump failure

Epidemiology

+

  • • Arrhythmia

    • Bradycardia (< 50 bpm) or tachycardia (> (230 - age)×0.8)

    • Ischemia-induced myocardial failure

    • Valvular or septal defects

    • Systemic or pulmonary hypertension

    • Myocarditis

    • Myocardiopathies

+

  • • Elevated right heart/central venous and jugular venous pressure

    • Decreased cardiac output

    • Peripheral hypoperfusion

    • Peripheral edema/pulmonary edema

+

  • • Intrinsic cardiac dysfunction

    • Myocardial ischemia

    • Arrhythmia

+

  • • Physical exam

    • ECG

    • Echocardiogram

+

  • • Aimed at underlying medical condition and optimizing cardiac output

    Opioids relieve pain, provide sedation, block adrenergic discharge, decrease right ventricular filling, and lessen stress on heart

    Diuretics decrease vascular volume, decrease right and left atrial pressures, and alleviate peripheral and pulmonary edema

    Chronotropes rarely indicated, should be used to raise heart rate only to tolerable levels

    Inotropes increase blood flow in the cardiovascular system

    Vasodilators in patients with elevated systemic vascular resistance

    • β-Blockers in those with ischemia and a rapid heart rate

    Vasoconstrictors are occasionally useful to increase coronary perfusion pressure

    • Transaortic balloon pump is effective in resuscitating selected patients with severe reversible LV dysfunction
