- W2010621423 abstract "Background: The use of metabolic drugs effective in addition to conventional therapy represents a significant challenge in patients with left ventricular dysfunction. Hypothesis: The aim of this double-blind, placebo-controlled study was to investigate the hemodynamic effects of acute intravenous (IV) administration of creatine phosphate (CP) and of short-term treatment in patients with congestive heart failure (CHF) from ischemic heart disease (IHD) or dilated cardiomyopathy in addition to conventional therapy. Methods: We compared the hemodynamic effects of exogenous creatine phosphate (CP) and placebo in a double-blind, crossover design study in 13 hospitalized patients (12 men, 1 woman, mean age 52 ± 8 years) with CHF. All patients were in New York Heart Association (NYHA) class II-III and received conventional pharmacologic therapy for CHF this was not changed during the study period. The study design consisted of two treatment periods (CP or placebo and placebo or CP, respectively) of 4 days each, separated by a 2-day washout interval. The intravenous infusion consisted of 6 g CP or placebo (acute treatment) or 6 g CP or placebo daily for 4 days (short-term treatment) diluted in 50 ml of NaCl 0.9%;infusion duration was about 10 min. Mono-bidimensional echocardiographic examination (Hewlett Packard So-nos 1000, with a 2.5 MHz transducer) was performed at baseline, after acute infusion, and 12 h after the end of short-term treatment. Data were analyzed by ANOVA and Student's t-test for paired data the results obtained after acute and short-term therapy were compared with the baseline values. Results: After placebo therapy, no significant change was observed. The results after treatment with CP showed a significant reduction of end-systolic diameter [baseline: 4.5 ± 0.6;acute: 4.2 ± 0.5, (p<0.001);short-term 4.3 ± 0.6 cm, (p<0.05)] and systemic vascular resistance (baseline: 1064.9 ± 483.7;acute: 947.5 ± 390.2 (p<0.05);short-term: 950.7 ± 394.3 dynescm-5 (p<0.05);moreover, a significant increase of percent ejection fraction [baseline:48 ± 12%;acute 53 ± 12% (p<0.01);short-term 52 ± 11 % (p<0.01)], and of percent fractional shortening [baseline: 25 ± 7;acute 28 ± 8 (p<0.05);short-term 28 ± 7% (p<0.05)] was observed. Conclusion: CP was shown to improve cardiac function, even in the presence of a conventional CHF pharmacologic therapy." @default.
