【Abstract】 Objective To evaluat the clinical efficacy of urgent percutaneous coronary intervention(PCI) on the elderly acute myocardial infarction(AMI) patients. Methods A total of 66 patients were identified for analysis: mean 68.3±10.2 years old(from 60 to 88 years), 57 men and 9 women, 18 patients over 75 years. All AMI patients were diagnosed by ECG as WHO diagnosis standard in 1979. Results Directly PTCA was performed on 62 patients and secondly on 4 patients after the treatment of dissolving thrombus were failed as observing for 90 minutes in hospitalizing. The distributes of infarction-elated arteries(IRA):24 for anterior descending branch, 11 for circumflex branch, 21 for right coronary artery. 73 stents(importation or home-made ) were implanted into 63 infarction-associated coronary vessels in 63 patients and the success rate were 100%, simplify PTCA was performed in 3 patients, remaining narrow rang 0～20%. The TIMI 3 for coronary circulation of 60 patients vs TIMI 2 for 5 patients, one patient no blood flowing. 2 patients died of cardiogenic shock after operation 24 hours. 52 discharged patients were follow up for (26.1±13.3) months(from 1 to 78 months),2 patients death occurred, 5 patients had chest pain again, 2 patients had AMI again. Conclusion The urgent percutaneous coronary intervention(PCI) on elderly AMI patients is an effective and safety method of restoring coronary circulation with few complications and high success rate of operation. It is special applicable to the patients who have heart source shock and contraindication of dissolving thrombus.更多还原
