Aim Assessment of long-term cardiac complications in the regional cohort of extremely low birth weight (ELBW) children born in 2002–2004. Material and Methods The study group comprising 81 children born as ELBW infants with the median birthweight of 890g (25th–75th percentile: 760–950) were evaluated at the mean age of 7 years. The control group included 40 children born full term. Echocardiography and 24-hour ambulatory blood pressure measurements were performed.

Moreover, the former ELBW children have higher blood pressure comparing to their peers.
