title: [Changes in hydroxybutyrate dehydrogenase and lactate dehydrogenase ratio after urologic operations].
abstract: In 58 patients subjected to urological surgery a statistically significant correlation was found between the repolarization disorder of ischaemic origin on the ECG and the changes in the alpha-HBDH/LDH ratio. After extensive interventions and particularly in aged subjects, the level of the LDH iso-enzyme of myocardial origin may rise without myocardial infarction. The rise is due to myocardial ischaemia, as proved by the ECG.
