3 Cardiogenic Shock Free Online FlashCards

What defines cardiogenic shock?

Cardiogenic shock is a critical reduction in the heart’s pumping ability that leads to inadequate tissue perfusion.

Does low blood pressure alone establish cardiogenic shock?

No. Hypotension is common, but shock requires evidence of organ hypoperfusion; blood pressure alone does not establish the diagnosis.

Which findings can signal congestion in cardiogenic shock?

Pulmonary edema, jugular venous distension, and peripheral edema can signal congestion.

What does a “cold and wet” hemodynamic pattern suggest?

A low cardiac index indicates reduced forward flow, while an elevated wedge pressure suggests increased left-sided filling pressure. Together, they fit a “cold and wet” pattern.

What is the immediate general approach to suspected cardiogenic shock?

Use rapid cardiac monitoring and IV access, assess oxygenation and perfusion, and urgently evaluate the cause while stabilizing the patient.

What tests commonly help evaluate cardiogenic shock?

Evaluation commonly includes a 12-lead ECG, laboratory tests such as lactate and cardiac biomarkers, chest imaging, and bedside echocardiography or point-of-care ultrasound when available.

What intervention is time-critical when acute myocardial infarction causes cardiogenic shock?

When acute myocardial infarction drives cardiogenic shock, urgent assessment for coronary revascularization is a time-critical, cause-directed intervention.

Which vasopressor is a reasonable preferred initial choice?

Norepinephrine is a reasonable preferred initial vasopressor when blood pressure support is needed.

How should IV fluids be approached in cardiogenic shock?

Avoid reflexive large-volume boluses. Assess volume status and the shock pattern, and give fluid only when clinically indicated with close reassessment.

What should be repeatedly reassessed during treatment?

Repeatedly reassess perfusion, congestion, adverse effects, and response to treatment; worsening findings call for prompt reassessment.

What is appropriate when perfusion worsens despite initial support?

Worsening perfusion warrants urgent multidisciplinary shock-team reassessment and consideration of advanced support or transfer to an appropriate center.

Which findings can signal organ hypoperfusion?

Confusion, cool or mottled skin, weak pulses, low urine output, rising lactate, and worsening kidney or liver function can indicate hypoperfusion.
