Cardiorenal Syndrome, Type 3 (Acute Reno-Cardiac)

ICD-10 Code
I51.9_1

Acute primary worsening of kidney function (AKI, e.g., glomerulonephritis or contrast injury) leading to acute cardiac dysfunction (e.g., heart failure, arrhythmia, ischemia).

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with acute renal insult (AKI) characterized by rapid rise in serum creatinine and oliguria, temporally associated with the subsequent development of acute cardiac dysfunction. Symptoms include dyspnea, orthopnea, and peripheral edema, with clinical evidence of volume overload and electrolyte imbalance (e.g., hyperkalemia) secondary to primary renal failure.

Clinical Examination Findings

Patient appears in acute distress with signs of fluid overload. Vitals: Tachycardic, hypertensive or hypotensive depending on cardiac output, tachypneic. Physical exam reveals jugular venous distension (JVD), bibasilar crackles on lung auscultation, and significant pitting edema (1+ to 4+) in lower extremities.

Treatment Protocol

Management focuses on stabilization of renal function and cardiac support. Strategy includes: 1) Optimization of fluid status via judicious diuresis or RRT (CRRT/HD) if refractory. 2) Correction of electrolyte abnormalities (e.g., hyperkalemia). 3) Cardiac support with inotropes or vasodilators as indicated. 4) Avoidance of nephrotoxic agents.
