Right Ventricular Function in Heart Failure
Right Ventricular Function in Heart Failure
Only a few studies evaluated the RV systolic function in the three categories of HF,
 regarding the importance of understanding changes in RV function on clinical presentation and
 outcome; it was essential to understand the prevalence and severity of RV dysfunction among
 the three groups and the degree of correlation between RV with LV systolic function.
Inclusion Criteria:

 -

 Adult patients of both gender who have the followiong criteria :

 (i) symptoms with or without signs of HF (ii) elevated natriuretic peptides (BNP ≥35pg/ mL
 or NT-proBNP≥125pg/mL) (iii) relevant structural heart disease: left ventricle hypertrophy
 (left ventricular mass index ≥115 g/m2 for males and ≥95 g/m2 for females) or left atrial
 enlargement (>34 mL/m2) or diastolic dysfunction (E/e'≥13 and a mean e' septal and lateral
 wall <9 cm/s) were included.

 Then patients were classified according to EF into HFpEF>50%, HFrEF<40% and HFmrEF >40% and
 <50%

 Exclusion Criteria:

 Patients with chronic obstructive pulmonary disease history of pulmonary embolism patients
 with respiratory failure
