RESUMEN
BACKGROUND: Peri-partum cardiomyopathy (PPCM) is a clinical heart failure that usually develops during the final stage of pregnancy or the first months following delivery. High maternal serum uric acid concentrations have been previous associated with heart failure and preeclampsia. OBJECTIVES: 1) To explored the clinical characteristics of PPCM patients; and 2) to determine the association between maternal serum uric acid concentrations and PPCM. METHODS: This is a retrospective population based case control study. Cases and controls were matched 1:4 (for gestational age, medical history of cardiac conditions and creatinine); conditional logistic regression was used to identify clinical parameters that were associated with PPCM. RESULTS: The prevalence of peripartum cardiomyopathy at our institution was 1-3832 deliveries (42/160,964). In a matched multivariate analysis high maternal serum uric acid concentrations were associated with PPCM (O.R 1.336, 95% C.I 1.003-1.778). Uric acid concentrations were higher within the Non-Jewish patients and mothers of male infant with PPCM in compare to those without PPCM (p value 0.003 and 0.01 respectively). CONCLUSION: PPCM patients had increased maternal serum uric acid concentrations. This observation aligns with previous report regarding the increased uric acid concentration in women with preeclampsia and congestive heart failure, suggestive of a common underlying mechanism that mediates the myocardial damage.
