Key result

Sodium dichloroacetate improves LV mechanical efficiency ~36% in CHF patients, whereas dobutamine shows no benefit.

P=0.03
n=10

Why the study?

Congestive heart failure involves impaired hemodynamics and reduced mechanical efficiency, and it was unknown whether sodium dichloroacetate improves these parameters by facilitating glucose and lactate consumption.

Does sodium dichloroacetate improve hemodynamic performance and mechanical efficiency in patients with NYHA class III-IV congestive heart failure compared to dobutamine?

Comparison

Implication

Hypothesis-generating for metabolic modulation in HF; does not support clinical use without randomized validation.

Key Points

This study aimed to assess whether sodium dichloroacetate enhances hemodynamic performance and mechanical efficiency in congestive heart failure.
Administered sodium dichloroacetate (50 mg/kg body weight) intravenously for 30 minutes to 10 patients with NYHA class III to IV heart failure.
Monitored hemodynamic variables, coronary sinus blood flow, and blood gas, glucose, and lactate levels for 2 hours.
Forward stroke volumes increased by 5.3 ml/beat (p < 0.02), and left ventricular mechanical efficiency improved from 15.2% to 20.6% (p = 0.03).
Myocardial oxygen consumption decreased from 19.3 to 16.5 ml/min (p = 0.06) with increased left ventricular minute work.

Population

10 patients with NYHA functional class III to IV congestive heart failure.

Intervention

Sodium dichloroacetate 50 mg/kg body weight administered intravenously for 30 minutes.

Comparator

Dobutamine 5 to 12.5 micrograms/kg per minute administered to the same patients for comparison.

Outcome

Hemodynamic variables, coronary sinus blood flow, blood gas, glucose and lactate levels, and left ventricular mechanical efficiency measured over 2 hours.surrogate

Main Result

Absolute Event Rate: 20.6% vs 15.8%

p-value: p=0.03

Intravenous sodium dichloroacetate improves left ventricular mechanical efficiency and stroke volume while reducing myocardial oxygen consumption in patients with severe congestive heart failure.

Bersin et al. (1994) studied Congestive heart failure (n=10). Sodium dichloroacetate vs. Dobutamine was evaluated on Left ventricular mechanical efficiency (p=0.03). Sodium dichloroacetate improved left ventricular mechanical efficiency from 15.2% to 20.6% (p=0.03) in patients with congestive heart failure, whereas dobutamine showed no significant change.
