Relationship Between Serum Levels of Pancreatic Exocrine Enzymes on Admission and Long-Term Clinical Outcomes in Patients with Acute Decompensated Heart Failure.

: Heart failure (HF) can damage organs because of poor perfusion and/or congestion. The interactions between HF and other organs have recently been studied; however, data on the interaction between HF and pancreatic exocrine function, which may affect fat and protein absorption and malnutrition, are scarce. We previously showed that the serum levels of pancreatic exocrine enzymes, as suggestive of pancreatic exocrine function, were low and associated with malnutrition or congestion in hospitalized patients with acute decompensated HF (ADHF). This study investigated the relationship between the serum levels of pancreatic exocrine enzymes and long-term outcomes in patients with ADHF. : We collected serum levels of pancreatic exocrine enzymes (amylase and lipase) from patients who were admitted to the cardiac intensive care unit due to ADHF. Patients undergoing dialysis and those with neoplasms were excluded. Patients were categorized as having high or low pancreatic exocrine enzyme levels in the first quartile upon admission. The association between low serum pancreatic exocrine enzyme levels at admission and the composite of death and ADHF readmission was assessed. : Of the 146 patients, 37 (25.3%) and 36 (24.7%) had low amylase and lipase levels, respectively. Patients with low lipase levels showed worse cumulative event-free survival than those with high lipase levels ( < 0.001). A low lipase level was associated with worse outcomes (hazard ratio: 1.96; = 0.012). : These findings suggest that low serum lipase levels may be a predictor of long-term outcomes in patients with ADHF.
