Abstract:
Background: Continuous positive airway pressure (CPAP) can improve left and right ventricular (LV and RV) func¬tion in patients with congestive heart failure (CHF).
Material and Methods: We have chosen 30 patients with CHF who were treated in Department of Cardiology, Shastin’s Central hospital. CHF etiology was ischemic and dilatation cardiomyopathy. Baseline respiratory rate, SpO2, heart rate, systolic and diastolic blood pressure, cardiac output, ejection fraction and Tricuspid Annular Plane Systolic Excursion (TAPSE) values were noted. All the measurements were repeated at the end of CPAP.
Statistical analysis: Statistical analysis performed by SPSS 17.0 program and we compared pre and post CPAP findings. P<0.05 was considered to be significant.
Results: After CPAP patients respiratory rate decreased from 23.63±4.72 to 20±3.74 per minute (р=0.01), SpO2 increased from 91.25±4.1% to 98.25±1.16%, heart rate decreased from 86.75±8.28 to 77.38±7.35 per minute (p=0.05), systolic blood pressure decreased from 107.88±17.94 mmHg to 97.75±14.78 mmHg (p=0.01), diastolic blood pressure decreased from 81.13±17.16 mmHg to 73.38±15.89 mmHg (p=0.01), cardiac output increased from 5.57±1.55 l/min to 5.76±1.86 l/min (p=0.01), ejection fraction increased from 27.81±7.66% to 31.7±7.97% (p=0.05), TAPSE increased from 1.49±0.25 mm to 1.69±0.23 mm (p=0.01) respectively. Pearson’s coefficient between dia¬stolic blood pressure and cardiac output is -0.282, between diastolic blood pressure and ejection fraction is -0,493, between diastolic blood pressure and TAPSE is -0.581 respectively.
Conclusion: CPAP improves LV, RV function and some respiratory parameters in patients with CHF
