[Comparative analysis of enteral feeding practices for prevention of gastrointestinal complications in infants with ductus-dependent congenital heart diseases].

Mesenterial hypoperfusion is one of the main pathogenetic factors of necrotizing enterocolitis (NEC) in infants with ductus-dependent congenital heart diseases. NEC in infants undergoing congenital heart surgery increases mortality and length of hospital stay. NEC is also associated with adverse neurodevelopmental outcome.

[Chronic renal disease and atrial fibrillation in patients with chronic heart failure].

Aim: To specify an association between reduced renal function and atrial fibrillation (AF) in patients with chronic heart failure (CHF).

Subjects And Methods: Three hundred and forty patients (200 males and 140 females, mean age 58 +/- 13 years) with CHF were examined. The causes of CHF were arterial hypertension in 44 (13%) patients, coronary heart disease (CHD) in 112 (33%), and their concomitance in 184 (54%).

[Renal dysfunction and mitral regurgitation in patients with chronic heart failure].

The objective of this study was to elucidate the relationship between mitral regurgitation (MR) and the glomerular filtration rate (GFR) in patients with chronic heart failure (CHF). A total of 340 patients with CHF (200 men and 140 women, mean age 58.0 +/- 12.
