Table 3:

Frequency of unexplained tachycardia or peripartum cardiomyopathy and their relationship with IL3RA levels in parturitions complicated by preeclampsia with severe features (sPE) per ancestry (N=50). Comparison placental IL3RA levels were set to 2-fold greater than average of the levels in sPE patients per ancestry.

IL3RA	PPCM or unexplained tachycardia	No PPCM or unexplained tachycardia
IL3RA 2-fold greater than PE average for ancestry	African – 1	African – 0
	Asian – 1	Asian – 0
	European – 1	European – 0
	Total – 3	Total – 0
IL3RA less than 2-fold of PE average for ancestry	African – 0	African – 8
	Asian – 0	Asian – 17
	European – 2	European – 20
