MO131THE SHRUNKEN PORE SYNDROME IS ASSOCIATED WITH POOR PROGNOSIS AND LOWER QUALITY OF LIFE IN HEART FAILURE PATIENTS- THE HARVEST-MALMÖ STUDY

Background and Aims The cardiorenal syndrome was studied in heart failure (HF) patients with respect to the “Shrunken pore syndrome” (SPS) that is characterized by a difference in renal filtration between cystatin C and creatinine, resulting in a low eGFRcystatin C/eGFRcreatinine-ratio. Method 373 patients hospitalized for HF were retrieved from the HeARt and brain failure inVESTigation trial (HARVEST-Malmö). We used CKD-EPI formulas for estimated glomerular filtration rate (eGFR). Presence of SPS was defined as eGFRcystatinC ≤60% of eGFRcreatinine. In Cox regression multivariate models, associations between SPS, risk of death and risk of 30-day re-hospitalization were studied. Associations between SPS and impaired quality of life (QoL) were studied using multivariate logistic regressions. Results SPS was associated with all-cause mortality (124 events; hazard ratio (HR) 2.35; confidence interval (CI95%) 1.17-4.71; p=0.016 and with 30-day re-hospitalization (70 events; HR 1.82; CI95% 1.04-3.18; p=0.036). Analyses of QoL, based on a Kansas City Cardiomyopathy Questionnaire overall score <50, revealed that SPS was associated with increased risk of low health-related QoL (odds ratios (OR) 2.15 (CI95% 1.03-4.49; p=0.042). Conclusion The results of this observational study show for the first time an association between SPS and poor prognosis in HF. Further studies are needed to confirm the results in HF cohorts and experimental settings to identify pathophysiological mechanisms.
