Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with progressive dyspnea on exertion, fatigue, and peripheral edema in the setting of known hyperdynamic state (e.g., anemia, thyrotoxicosis, AV fistula, or obesity hypoventilation). Symptoms are characterized by high cardiac output requirements exceeding systemic delivery capacity. Denies orthopnea or PND.
Clinical Examination Findings
Vitals reveal tachycardia, wide pulse pressure, and warm extremities. Cardiac exam demonstrates hyperdynamic precordium, loud S1, and flow murmurs. Peripheral exam shows bounding pulses, flushed skin, and pitting edema. JVP may be elevated, but often less prominent than in low-output failure.
Treatment Protocol
Primary management focuses on treating the underlying etiology (e.g., correction of anemia, management of thyrotoxicosis, or surgical closure of AV fistula). Diuretic therapy should be used with caution as patients are often preload-dependent. Avoid excessive afterload reduction unless hypertension is present.
