ABSTRACT
BACKGROUND:
Although peripartum cardiomyopathy (PPCM) is a fatal disease affecting young patients and fetuses, little is known about its recent prognosis and risk factors. This study investigated temporal trends in clinical characteristics and outcomes for PPCM in a nationwide multicenter registry. METHODS ANDRESULTS:
The study population comprised 340 patients (mean age, 33 years) who were diagnosed with PPCM between January 2000 and September 2022 in 26 tertiary hospitals in South Korea. PPCM was defined as heart failure with left ventricular ejection fraction ≤45% and no previously known cardiac disease. The main study outcomes included time to the first occurrence of all-cause death, heart transplantation, and cardiovascular hospitalization. The diagnosis of PPCM cases increased notably during the study period (P<0.001). However, clinical outcomes showed no significant improvement (all-cause death for 10 years 0.9% [2000-2010] versus 2.3% [2011-2022], P=0.450; all-cause death and heart transplantation for 10 years 3.6% [2000-2010] versus 3.0% [2011-2022] P=0.520; all-cause death, heart transplantation, and cardiovascular hospitalization for 10 years 11.7% [2000-2010] versus 19.8% [2011-2022], P=0.240). High body mass index (hazard ratio [HR], 1.106 [95% CI, 1.024-1.196]; P=0.011), the presence of gestational diabetes (HR, 5.346 [95% CI, 1.778-16.07]; P=0.002), and increased baseline left ventricular end-diastolic dimension (HR, 1.078 [95% CI, 1.002-1.159]; P=0.044) were significant risk factors for poor prognosis.CONCLUSIONS:
While the incidence of PPCM has increased over the past 20 years, the prognosis has not improved significantly. Timely management and close follow-up are necessary for high-risk patients with PPCM with high body mass index, gestational diabetes, or large left ventricular end-diastolic dimension.Mots clés
