Long-term outcome of percutaneous coronary intervention: the significance of native coronary artery disease progression

The extensive use of stents during percutaneous coronary intervention (PCI) is associated with concerns about their potential adverse effects. In-stent restenosis and stent thrombosis definitely significantly affect the PCI outcome. However, review of recent relevant studies suggests that stent-related problems may have been somewhat overestimated when compared to coronary artery disease (CAD) progression at nonstented coronary segments as causative factors of adverse cardiac clinical events late (>30 days) post-PCI. Both stent-related problems and native CAD progression have to be equally addressed to optimize the PCI clinical benefit.

Four‐year clinical outcome of sirolimus‐ and paclitaxel‐eluting stents compared to bare‐metal stents for the percutaneous treatment of stable coronary artery disease

Background : There are limited data on the long‐term safety and efficacy profile of coronary stent implantation in patients with stable coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI). Objective : We aimed to assess the 4‐year clinical outcome in patients who received a bare‐metal stent (BMS), sirolimus‐eluting stent (SES), or a paclitaxel‐eluting stent (PES) for the percutaneous treatment of stable angina in our center during 2000–2005. Methods : In the study period, a total of 2,449 consecutive patients (BMS = 1,005; SES = 373; and PES = 1071) underwent a PCI as part of three historical PCI‐cohorts for stable angina and were routinely followed for the occurrence of major adverse cardiac events (MACE). Results : At 4 years follow‐up, 264 BMS patients (26.8%) had a MACE, compared to 75 SES patients (20.9%) and 199 PES patients (23.9%). Multivariate analysis showed that SES and PES were superior to BMS with respect to MACE [hazard ratio (HR) = 0.62, 95% confidence interval (CI): 0.47–0.81; HR = 0.67, 95% CI: 0.55–0.82, respectively]. The occurrence of MACE was significantly lower in the SES and PES population, primarily due to less target‐vessel revascularization (TVR) procedures (HR = 0.53, 95% CI: 0.37–0.75; HR = 0.71, 95% CI: 0.62–0.81, respectively). The occurrence of early, late, and very late stent thrombosis was equally rare with each stent type. There were no significant differences between SES and PES on death, myocardial infarction, TVR, and MACE. Conclusion : These findings suggest that SES and PES result in decreased TVR procedures and MACE compared to BMS at 4 years follow‐up. SES or PES implantation should be the preferred choice over BMS for patients with stable CAD undergoing PCI. © 2010 Wiley‐Liss, Inc.     

Comparison of sirolimus-, paclitaxel-, and everolimus-eluting stent in unprotected left main coronary artery percutaneous coronary intervention

ObjectivesThis retrospective study evaluated the outcomes of patients who underwent unprotected left main coronary artery (ULMCA) percutaneous coronary intervention (PCI) with different types of drug-eluting stents (DES).BackgroundThe standard of care for patients with ULMCA is coronary artery bypass surgery. However, current guidelines recommend PCI in clinical conditions where there is an increased risk of adverse surgical outcomes. Clinical outcomes of patients undergoing ULMCA PCI with different types of drug-eluting stents (DES) are unknown.MethodsData from a multicenter international registry, which included 239 consecutive patients from four institutions who ULMCA PCI with DES, were collected.ResultsThere were 42 patients receiving paclitaxel-eluting stent (PES), 158 patients receiving sirolimus-eluting stent (SES), and 39 patients receiving everolimus-eluting stent (EES). There was no statistical difference in major adverse cardiovascular events, cardiac death, myocardial infarction, target lesion revascularization, and stent thrombosis among PES, SES, and EES at 30 days and 1 year.ConclusionsThere are no differences in clinical events among patients receiving PES, SES, and EES for ULMCA disease.     

Comparison between sirolimus- and paclitaxel-eluting stents for the treatment of older patients affected by coronary artery disease: results from a single-center allcomers registry

The treatment of elderly patients with coronary artery disease (CAD) is challenging because this population is complex and greatly expanding. Drug-eluting stents (DES) generally improve the outcome in high-risk cases. We evaluated the clinical impact of different first-generation DES, i.e., sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES), in this context. A prospective, nonrandomized, single-center, allcomers registry consecutively enrolling all patients aged ≥75 years eligible for percutaneous coronary intervention (PCI) with DES was carried out. Only one type of DES was implanted per protocol for each patient. Two groups were identified according to the type of implanted stent, i.e., SES and PES. The primary end point encompassed major adverse cardiac events (MACE), including death, myocardial infarction, and target lesion revascularization (TLR). The secondary end point encompassed the rate of definite/probable stent thrombosis and target vessel revascularization (TVR). From June 2004 to May 2008, 151 patients were enrolled. Among them, 112 (74.2%) received SES and 39 (25.8%) received PES. Baseline clinical characteristics were similar, while few angiographic features (ostial location, stent diameter, proximal reference vessel diameter) showed minor differences. At the median follow-up of 22.6 months, primary and secondary end points did not significantly differ in terms of MACE (SES 12.5% vs PES 20.5%, P = 0.3), death (SES 5.4% vs PES 7.7%, P = 0.7), myocardial infarction (SES 4.5% vs PES 10.3%, P = 0.2), TLR (SES 2.7% vs PES 2.6%, P = 1.0), stent thrombosis (SES 1.8% vs PES 5.1%, P = 0.3), and TVR (SES 1.8% vs PES 0%, P = 0.6). In this real-world population of elderly patients treated by DES–PCI for CAD, the overall efficacy and safety have been excellent in both DES, and the choice between SES and PES did not influence the clinical outcome.

Stenting of unprotected left main coronary artery in patients with low preoperative risk of coronary artery bypass grafting

INTRODUCTION: Available data indicate that stenting of the left main coronary artery (LMN) is safe and effective. Restenosis remains the main factor limiting the effectiveness of percutaneous coronary intervention (PCI). AIM: To evaluate immediate and long-term results of treatment of patients with LMN disease and low preoperative risk of coronary artery bypass grafting. METHODS: Coronary stents were implanted into LMN in 64 patients. The following strategy was applied: drug eluting stent (DES) for LMN diameter < or =3.5 mm (28 subjects) and bare metal stent (BMS) for LMN diameter >3.5 mm (36 subjects). Patients enrolled in the study underwent clinical evaluation and coronary angiography. Immediate effect of the procedure and main adverse cardiac events were assessed: death, myocardial infarction and additional target lesion or non-target lesion revascularization. RESULTS: Angiographic and clinical effectiveness of the interventions was 100%. Full revascularisation of ischaemic regions of the myocardium was performed. Mean clinical follow-up period was 9.4+/-4.0 months. Neither death nor myocardial infarction occurred. Additional PCIs were performed in 11 (17.2%) patients; however, target vessel revascularisation (TVR) rate within LMN was 9.4% (i.e. 6 subjects with BMS), and non-TVR rate was 7.8% (5 subjects). CONCLUSIONS: LMN stenting is associated with high effectiveness of PCI in patients with low operative risk. Long-term follow-up revealed low incidence of major adverse cardiac events. Strategy of selective use of DESs in the study group produced good clinical outcome. Multivessel disease with LMN stenosis was associated with high rate of additional revascularisation of other vessels. Further improvement of treatment results may be obtained by more common use of DES for multivessel disease and LMN diameters larger than 4.0 mm.     

Long-term outcome of first-generation metallic coronary stent implantation in patients with coronary artery disease: observational study over a decade.

BACKGROUND: In the era of drug-eluting stents, percutaneous coronary intervention (PCI) has been considered an established therapeutic modality for patients with coronary artery disease (CAD). However, little is known about the long-term prognosis. METHODS AND RESULTS: Using data obtained from a single-center registry for cases of first-generation bare metallic stent (BMS) implantation, a 10-year follow-up study in patients with CAD was performed. Data for 125 serial patients (aged 62+/-9 years, 104 males) in whom a BMS was successfully implanted was analyzed. Cardiac death (n=16 [12.8%]), including sudden cardiac death (n=9 [7.2%]), non-cardiac death (n=17 [13.6%]) and non-fatal acute myocardial infarction (n=16 [12.8%]) were documented. At 10 years, cumulative probabilities of target and non-target lesion revascularization were 20.5% and 41.5%, respectively, and only 39.2% of the patients were free from cardiac events (cardiac death/myocardial infarction/unplanned revascularization). Age and left ventricular ejection fraction (LVEF) were significant predictors of total death, and LVEF and the use of diuretics were predictors of cardiac events. CONCLUSIONS: Stabilization of the initial stented site was relatively good and the majority of cardiac events might have originated in non-target lesions. Prevention of systemic arteriosclerosis progression is important for patients with CAD, even after successful PCI.
