To detect diaphragmatic dysfunction in patients with chronic heart failure (CHF) via assessment of structural and functional state of external respiration.
The study was conducted at the Almazov National Medical Research Center and included 58 subjects. There were 40 patients with CHF and 18 ones without CHF (control group). Inclusion criterion for the main group was CHF NYHA class II—IV. Exclusion criteria for both groups were pulmonary diseases, morbid obesity, abdominal diseases and anemia. We performed ultrasonic assessment of structural (thickness) and functional (thickening fraction and excursion) state of diaphragm under calm and deep inhalation/exhalation. External respiration was assessed using spirometry functions of a ventilator.
Patients with CHF had a thicker diaphragm on both sides and smaller volume of deep inhalation. Diaphragm thickening index was significantly less under deep inhalation on the right. Patients with CHF had a larger excursion of the right and left domes of the diaphragm under calm breathing, whereas no significant differences were found under deep breathing. We found a moderate positive linear correlation between CHF and diaphragm thickness on both sides under calm inhalation.
Structural and functional diaphragmatic dysfunction makes a contribution to respiratory failure in patients with CHF.
