Abstract:
Objective To evaluate the clinical efficacy of primary intracoronary stenting in the infarct related artery in elderly patients after acute myocardial infarction(AMI). Methods Percutaneous transluminal coronary angioplasty(PTCA) plus primary coronary stenting was performed for 41 AMI patients(≥70 years) within 12 hours from the onset of chest pain. Infarct related arteries were left anterior descending artery in 21 patients(51 2%), left circumflex in 7(17 1%), right coronary artery in 13(31 7%). Thrombolysis in myocardial infarction (TIMI) showed that blood flow was grade 0 in 29 patients, grade 1 in 7, grade 2 in 5. Results Forty eight stents were implanted in the infarct related artery for 41 patients. One patient died of cardiac shock during the procedure, and the success rate was 97 6%(40/41). Grade 3 of blood flow after TIMI was gained in 37 patients(90 2%). One patient died of renal failure while hospitalizing. The clinical successful rate was 95 1%(39/41). Thirty six patients were followed up, 1 patient with restenosis of infarct related artery was performed cutting balloon angioplasty, and 1 patient with congestive heart failure was rehospitalized. Other 34 patients did not manifested angina pectoris. Conclusions Primary coronary stenting for the infarct related artery in elderly patients after AMI is safe and effective with a high successful rate and less complications.
