摘要：Objectives To comparethe short and mid - term outcomes in cases of percuta-neous transluminal coronary angioplasty (PTCA) inpatients with unstable v stable angina. MethodsPatients selected for PTCA/stenting were divided into two groups, one with stable angina pectoris (SAgroup, n--92) and one with unstable angina pectoris(UA group, n = 112). The outcomes of coronary angiographies (CAG), initial (30-d) success of theprocedure, and follow- up status in the two groupswere compared. Results Baseline characteristicswere similar, although the patients with unstablesymptoms more females ( P＜ 0.05), and had a higheraverage CCS class ( P＜ 0.05) and a higher incidenceof postinfarction angina ( P＜ 0. 01 ). The frequency of"complex" stenosis in patients with unstable anginawas higher than that of patients with stable angina,33% v 20% (P＜0.01). A total of 309 vessels accepted the procedure; including 210 stents were successfully delivered to 156 patients. 143 and 67 stentswere implanted in the UA and SA group, respectively(P＜ 0.01 ). No major complication occurred in thetwo groups, except 12 patients experienced reoccurring chest pain initially, 9 in UA group v 3 in SAgroup ( P＜ 0.05). The averaged six - month follow -up status was compared too. Only 3 cases developedmyocardial infarction, including 2 patients with unstable angina. 12 and 16 reoccurring chest pains werefound in the two groups, respectively (13% in SAgroup vs 14% in UA group). There were no significant differences between groups in rates of clinicalrestenosis, follow- up angina class, or overall clinicalsuccess. Conclusions Patients with unstable anginareceiving PTCA/stenting have similar complication,restenosis, and initial and midterm success rate ascompared to patients with stable symptoms with strictcases select and careful preparation.
