What hemodynamic pattern is typical of advanced left-sided heart failure?

• A. Elevated left-sided filling pressures with preserved or reduced cardiac output depending on compensation
• B. Decreased LVEDP with low pulmonary pressures
• C. Elevated right atrial pressure only
• D. Elevated left-sided filling pressures and reduced cardiac output

Answer: (D)

Advanced left-sided heart failure typically shows high pressures on the left side of the heart with reduced forward flow. When the left ventricle struggles to fill and eject blood, the filling pressures rise—left atrial pressure and LV end-diastolic pressure (reflected clinically as elevated pulmonary capillary wedge pressure). This backward pressure causes pulmonary congestion and edema. At the same time, the failing ventricle loses its ability to generate adequate stroke volume, so cardiac output falls. So the hallmark pattern is elevated left-sided filling pressures together with reduced cardiac output, which matches the decompensated state of the left heart.
