Peripartum cardiomyopathy (PPCM) is a specific cardiomyopathy in which heart failure develops due to reduced myocardial contraction during pregnancy or in the postpartum period in women without a previous history of heart disease. The epidemiology of PPCM has been reported in various countries and areas, and the incidence of PPCM differed among these reports. The incidence was highest (1 in 102 deliveries) in Nigeria and lowest (1 in 15,533 births) in Japan. The incidence was higher in African-Americans than in other races in several reports from the United States, and was also high in African countries and Haiti, indicating that the risk for PPCM is highest in the black race. However, the study design and definition of PPCM differ among studies, and these differences may influence the incidence. Moreover, the incidence of PPCM and the maternal mortality rate were well correlated. Since maternal mortality reflects the level of perinatal health care and hygiene, this finding suggests that the extent of perinatal care is partly related to the incidence of PPCM, which reflects heart failure and cardiomyopathy of unknown cause in women.
