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
ABSTRACT
@#ObjectiveTo investigate the effects of low dose testosterone undecanonate (TU) and dehydroepiandrosterone (DHEA) on serum androgen levels in male adult rabbits postinfarction congestive heart failure (CHF) model.Methods48 male 4～5 months old New Zealand rabbits were randomly assigned to ligation of first branch of left coronary artery (n=40) or sham operation (n=8). 3 weeks later, 30 survived model rabbits were randomly treated with TU 3 mg/kg per 2 weeks intramuscular injection (TU group, n=10), DHEA 3 mg/kg/d oral (DHEA group, n=10) or placebo (placebo group, n=10) for 3 months. Serum androgen changes were recorded at 0th, 3rd and 15th week.ResultsAt 3rd week after peration, left ventricular ejection fraction of model animals was 47.6±4.5% lower than that of the sham group (66.7±5.8%) (P<0.05). Serum free testosterone level of model animals returned to normal ranges after low dose TU or DHEA treatment, otherwise DHEAS level was higher than the sham group (P<0.05).ConclusionThe doses used in this research reached physiological dosage to male adult rabbits in postinfarction CHF model.
ABSTRACT
Objective:To research the effect of Shengmai capsules on the matrix metalloproteinase(MMPs)& tissue inhibitor of metalloproteinase(TIMPs)in chronic congestive heart failure(CHF)rats.Methods:75 SD female rats weredivided randomly into 5 groups:sham-operation group(A),CHF model group(B),CHF model treated by Shengmai capsules group(Shengmai capsule group,C),CHF model treated by Captopril group(Captopril group,D),CHF model treated by Shengmai capsule and Captopril group(shengmai capsule&captopril group,E),15 rats each group.Suprarenal abdominal artery constriction was operated to prepare CHF rat models.After 7 week treating respectively,the contents of MMP-3&TIMP-1 of cardiac muscle in rats were detected.Results:The content of cardiac MMP-3 was higher in group B than in group A(P
