[The effect of ischemic preconditioning on early death in acute Q-wave myocardial infarction].
Ischaemic preconditioning is still a laboratory-based phenomenon, not conclusively documented in patients. In this study it was of interest whether there is any beneficial influence of ischemic preconditioning on 30-day in-hospital mortality in patients undergoing acute Q-wave myocardial infarction. All men and women admitted to our ward between December 1994 and July 1996 with their first acute Q-wave myocardial infarction were divided into two groups. I group--29 patients with prodromal angina, defined as chest pain episodes in the 24-hour period before myocardial infarction. II group--25 patients who showed no chest pain before infarction onset. Both groups did not differ statistically in view of age, sex, smoking habits and adjunctive therapy. The use of streptokinase in the I and II group was also similar--in 58.6% and 56% of patients respectively in the first and second group. In the I group there was no fatal outcome, all 5 death cases occurred in the II group. The results are statistically significant and suggest lower in-hospital mortality in Q-wave myocardial infarction patients with previous ischaemic preconditioning.
