What is the typical hemodynamic profile for cardiogenic shock in terms of systemic vascular resistance?

• A. Decreased
• B. Increased
• C. Normal
• D. Variable

Answer: (B)

In cardiogenic shock, the typical hemodynamic profile is associated with increased systemic vascular resistance (SVR). This condition arises when the heart is unable to effectively pump blood due to various reasons such as myocardial infarction, severe heart failure, or other cardiac events. As a result, there is decreased cardiac output, which leads to inadequate perfusion of tissues. The body compensates for the decreased cardiac output by activating various neurohormonal mechanisms, including the sympathetic nervous system, which increases peripheral vascular resistance. Additionally, the renin-angiotensin-aldosterone system (RAAS) is activated, resulting in vasoconstriction and sodium retention. This effect raises systemic vascular resistance as the body attempts to maintain blood pressure and perfusion to vital organs despite the failing heart. In this context, the increased systemic vascular resistance is a compensatory mechanism in response to the reduced ability of the heart to pump effectively, highlighting an important feature of the hemodynamic profile in cardiogenic shock.
