**3. Epidemiology**

PPCM constitutes less than 1% of all cardiovascular events related to pregnancy. It is more common in Africa, 1:300 pregnancies. This may be due to the consumption of kanwa, a tradition, for 40 postpartum days. Kanwa is a dry salt and causes hypervolemia and hypertension. Ninety percent of PPCM occurs within 2 months of delivery [3]. In a recently concluded study about the incidence of PPCM from 43 countries, affecting females from all ethnicity and all continents, the incidence widely differs depending on geographic location. PPCM was common in Nigeria (1100), Haiti (1300), South Africa (11,000), Canada (12,400), and Denmark (110,149) and was lowest in Japan (1,20,000 live births). There are case reports from other countries [4]. Hence the information is not complete as many countries are not having a registry. The higher incidence in Nigeria may be related to abovementioned postpartum high salt intake or may be a genetic factor superimposing the geographic and dietary variabilities [5].
