OBJECTIVETo investigate the impact of depression on clinical outcome of patients undergoing revascularization.
METHODSSelf-rating depression scale (SDS) assessment was made before and after coronary artery bypass grafting (CABG, n = 345) and percutaneous coronary intervention (PCI, n = 308) procedure. Patients were divided into depression and non-depression group. All patients were followed up for 12 months after procedure for the occurrence of rehospitalization and major adverse cardiovascular events (MACE) including all-cause mortality, nonfatal myocardial infarction or target lesion revascularization.
RESULTSDepression was present in 40.9% (n = 141) of patients after CABG, which was significantly higher than before procedure (24.3%, P < 0.01). The MACE rate was significantly higher in patients with post-procedure depression [8.5% (12/141)] than in patients without depression [2.9% (6/204), P < 0.05] and the incidences of target lesion revascularization and rehospitalization were also significantly higher in depression patients than in non-depression patients during the 12 months follow-up (all P < 0.05). Depression was present in 36.4% (n = 112) of patients after PCI, which was significantly higher than that before procedure (28.6%, P < 0.05). The MACE rate [8.0% (9/112) vs. 2.0% (4/196)] and rehospitalization rate [12.5% (14/112) vs. 4.6% (9/196)] were significantly higher in depression patients than in patients without depression during the 12 months follow-up (P < 0.05). There was no significant difference on SDS score between the PCI and CABG before the procedure. However, after the procedure, the SDS score for patients undergoing CABG was significantly higher than in patients undergoing PCI (48.9 ± 9.8 vs. 45.7 ± 10.5 P = 0.01). The level of serum IL-6 was significantly higher in depression patients than in patients without depression (P < 0.05).
CONCLUSIONPrevalence of depression is high in patients treated with revascularization procedures and is linked with poor post-procedure prognosis.

BACKGROUNDRandomized clinical trials have demonstrated equivalent safety to bare-metal stents after drug-eluting stents (DES) implantation. However, the DES thrombosis in randomized trials could not be comparable to those observed in clinical practice, frequently including off-label indications. This study sought to assess the incidence of DES thrombosis after implantation of DES in patients with real world coronary artery disease (CAD) in China.
METHODSFrom December 2001 to April 2007, 8190 consecutive patients received the treatment with DES, 5412 patients completed one year follow-up: 2210 with sirolimus-eluting stent Cypher, 1238 with paclitaxel-eluting stent Taxus and 1964 with Chinese sirolimus-eluting stent Firebird. After two years of follow-up, there were 2176 patients (1245 Cypher, 558 Taxus and 373 Firebird). All patients were treated with aspirin and clopidogrel over at least 9 months.
RESULTSAmong 8190 patients, 17 patients had acute stent thrombosis (0.24%): 7 in the Cypher group, 4 Taxus and 6 Firebird; 23 patients had subacute stent thrombosis: 8 Cypher, 6 Taxus and 9 Firebird. The incidence of acute and subacute thrombosis was 0.49%: 0.50% Cypher, 0.63% Taxus and 0.41% Firebird. The incidence of late thrombosis at one year followup was 0.63%: 0.63% Cypher, 0.88% Taxus and 0.46% Firebird; at two year follow-up the incidence was 0.74%: 0.72% Cypher, 0.90% Taxus and 0.54% Firebird. There was no significant difference among three groups at 1 year and 2 years follow-up.
CONCLUSIONThe first generation DES in the treatment of complex lesions are safe and effective if patients are aggressively treated with dual antiplatelet agents.

OBJECTIVETo observe the incidence rate of stent thrombosis after implantation of drug-eluting stents (DES) in patients with coronary artery disease (CAD) in the real world.
METHODSA total of 8190 consecutive CAD patients underwent implantation with Cypher or Cypher Select stents (Cordis, USA, n = 2986), TAXUS stents (Boston Scientific Corp., USA, n = 1587) and Chinese Rapamycin eluting stents (Firebird, Microport Medical Company, China, n = 3617) for enrolled in this single center registry study from Dec.2001 to April 2007. One-year follow-up was completed in 5412 patients (2210 Cypher or Cypher select stents, 1238 TAXUS stents and 1964 Firebird stents). Two-year follow-up was finished in 2176 patients (1245 Cypher or Cypher Select stents, 558 TAXUS stents and 373 Firebird stents). 80.1% of all the lesions were the type B2 and type C lesions. All patients were treated with aspirin plus clopidogrel for at least 9 months post DES.
RESULTSAmong 8190 patients, 17 patients had acute stent thrombosis (0.21%): 7 in the Cypher group, 4 in the TAXUS group, 6 in the Firebird group; 23 patients had subacute stent thrombosis (0.28%): 8 in Cypher group, 6 in TAXUS group and 9 in Firebird group. The incidence rate of acute and subacute thrombosis was 0.49% (40/8190) and incidence of thrombosis was similar among the three groups (0.50% in Cypher group, 0.63% in TAXUS group and 0.41% in Firebird group, P > 0.05). One-year follow-up showed that late thrombosis rate was 0.63 % (34/5412) and similar among the groups (0.63% in Cypher group, 0.89% in TAXUS group and 0.46% in Firebird group, P > 0.05). Two-year follow-up showed that late thrombosis rate was 0.74 % (16/2176) and was similar among the 3 groups (0.72% in Cypher group, 0.90% in TAXUS group and 0.54% in Firebird group, P > 0.05).
CONCLUSIONThis study indicates that using the first-generation DES to treat complex coronary lesions is safe and effective and the incidence of late thrombosis remains low (< 1%) under double antiplatelet treatment.

BACKGROUND/AIMS: Although complex bifurcation stenting in patients with non-left main (LM) bifurcation lesions has not yielded better clinical outcomes than simpler procedures, the utility of complex bifurcation stenting to treat LM bifurcation lesions has not yet been adequately explored. METHODS: In the present study, patients who underwent LM-to-left anterior descending (LAD) coronary artery simple crossover stenting to treat significant de novo distal LM or ostial LAD disease, in the absence of angiographically significant ostial left circumflex (LCX) coronary artery disease, were consecutively enrolled. The frequencies of 3-year major adverse cardiovascular events (MACEs; cardiac death, myocardial infarction, and target lesion revascularization), were analyzed. RESULTS: Of 105 eligible consecutive patients, only 12 (11.4%) required additional procedures to treat ostial LCX disease after main vessel stenting. The mean percentage diameter of ostial LCX stenosis increased from 22.5% +/- 15.2% to 32.3% +/- 16.3% (p < 0.001) after LM-to-LAD simple crossover stenting. The 3-year incidence of MACEs was 9.7% (cardiac death 2.2%; myocardial infarction 2.2%; target lesion revascularization 8.6%), and that of stent thrombosis 1.1%. Of seven cases (7.5%) requiring restenosis, pure ostial LCX-related repeat revascularization was required by only two. CONCLUSIONS: Simple crossover LM-to-LAD stenting without opening of a strut on the LCX ostium was associated with acceptable long-term clinical outcomes.

9.Optimization of Stent Deployment by Intravascular Ultrasound.
The Korean Journal of Internal Medicine 2012;27(1):30-38
Intravascular ultrasound (IVUS) is a useful diagnostic method that provides valuable information in addition to angiography regarding the coronary vessel lumen, dimensions, plaque burden, and characteristics. The major use of IVUS in coronary intervention is to guide interventional strategies and assess optimal stent deployment. Since the introduction of the drug-eluting stent (DES), concerns about restenosis have decreased. However, high-risk lesion subsets are being routinely treated with DESs, and the incidence of suboptimal results after stent deployment, such as stent underexpansion, incomplete stent apposition, edge dissection, geographic miss, and the risk of stent thrombosis, have correspondingly increased. Thus, optimization of stent deployment under IVUS guidance may be clinically important. In this review, we focus on the potential role of IVUS in stent optimization during percutaneous coronary intervention and its clinical benefits.

BACKGROUND/AIMS: In the bare-metal stent era, routine follow-up coronary angiography (RFU CAG) was used to ensure stent patency. With the advent of drug-eluting stents (DESs) with better safety and efficacy profiles, RFU CAG has been performed less often. There are few data on the clinical impact of RFU CAG after second- or third-generation DES implantation in clinically stable patients with coronary artery disease; the aim of this study was to examine this issue. METHODS: We analyzed clinical outcomes retrospectively of 259 patients who were event-free at 12-month after stent implantation and did not undergo RFU CAG (clinical follow-up group) and 364 patients who were event-free prior to RFU CAG (angiographic follow-up group). Baseline characteristics were compared between the groups. RESULTS: The Kaplan-Meier estimated total survival and major adverse cardiac event (MACE)-free survival did not differ between the groups (p = 0.100 and p = 0.461, respectively). The cumulative MACE rate was also not different between the groups (hazard ratio, 0.85; 95% confidence interval, 0.35 to 2.02). In the angiographic follow-up group, 8.8% revascularization was seen at RFU CAG. CONCLUSIONS: RFU CAG did not affect long-term clinical outcome after second- or third-generation DES implantation in clinically stable patients.
