The management of conditioned nutritional requirements in heart failure.
Patients suffering from congestive heart failure exhibit impaired myocardial energy production, myocyte calcium overload and increased oxidative stress. Nutritional factors known to be important for myocardial energy production, calcium homeostasis and the reduction of oxidative stress, such as thiamine, riboflavin, pyridoxine, L-carnitine, coenzyme Q10, creatine and taurine are reduced in this patient population. Furthermore, deficiencies of taurine, carnitine, and thiamine are established primary causes of dilated cardiomyopathy. Studies in animals and limited trials in humans have shown that dietary replacement of some of these compounds in heart failure can significantly restore depleted levels and may result in improvement in myocardial structure and function as well as exercise capacity. Larger scale studies examining micronutrient depletion in heart failure patients, and the benefits of dietary replacement need to be performed. At the present time, it is our belief that these conditioned nutritional requirements, if unsatisfied, contribute to myocyte dysfunction and loss; thus, restoration of nutritional deficiencies should be part of the overall therapeutic strategy for patients with congestive heart failure.

Statin precipitated lactic acidosis?
An 82 year old woman was admitted with worsening dyspnoea. Arterial blood gases were taken on air and revealed a pH of 7.39, with a partial pressure of CO2 (pCO2) of 1.2 kPa, pO2 of 19.3 kPa, HCO3 of 13.8 mmol/litre, and base excess of -16.3 mmol/litre: a compensated metabolic acidosis with hyperventilation induced hypocapnia, which is known to be a feature of lactic acidosis. There was also an increased anion gap ((Na140 + K4.0) - (Cl 106 + HCO3 13.8) = 24.2 mEq/litre (reference range, 7-16)), consistent with unmeasured cation. Lactate was measured and found to be raised at 3.33 mmol/litre (reference range, 0.9-1.7). After exclusion of common causes of lactic acidosis Atorvastatin was stopped and her acid-base balance returned to normal. Subsequently, thiamine was also shown to be deficient. The acidosis was thought to have been the result of a mitochondrial defect caused by a deficiency of two cofactors, namely: ubiquinone (as a result of inhibition by statin) and thiamine (as a result of dietary deficiency).
