Abstract
Aim:To explore the relationship between pre-infarction angina and coronary thrombolysis-reperfusion in patients with acute myocardial infarction(AMI).Methods: By comparing the condition of 27 patients who had unstable angina during one week before AMI with that of 25 patients who had no pre-infarction angina,we found that the two groups did not differ significantly in terms of clinical base-line characteristics.The size of infarction was estimated based on the level of cardiacenzyme and ECC measurements (∑R,NQ).The time of reopening was defined from the start of thrombolytic therapy to the time when ST-segment elevation abruptly decreased by 50%.Results:Reopening occurred within 30 min after the start of treatment in 33% of the patients with pre-infarction angina,but in none of those without pre-infarction angina(P<0.005).Reopening rates at 60 min were 59% and 36% in the two groups,respectively(P<0.005).The duration of reperfusion were (49±16) min and (69±19) min respectively(P<0.05).The cardiac enzymatic indexes which reflected infarction size were all significantly lower in patients with pre-infarction angina than in those without (P<0.05,respectively).The ECG showed a higher R waves and a smaller numnber of Q waves in the group with pre-infarction angina the in the group without (P<0.05,respectively).Conclusion:The thrombolytic therapy is more effective and the size of infarction is smaller in patients with pre-infarction angina.The preinfarction angina could be regarded as a sensitive predictor for applying coronary thrombolysis promptly to patients with AMI.关键词
