Impact of the time-to-target rate of urine volume concept on the outcome of acute decompensated heart failure.

BACKGROUND: Early decongestion with diuretics could improve clinical outcomes. This study aimed to examine the impact of the time-to-target rate of urine volume (T2TUV) concept on the outcome of acute decompensated heart failure (ADHF). METHODS: This multicenter retrospective study included 1670 patients with ADHF who received diuretics within 24 h of admission. T2TUV was defined as the time from admission to the rate of urine volume of 100 ml/h. The primary outcomes were in-hospital death, mortality, and re-hospitalization for 1 year. RESULTS: A total of 789 patients met the inclusion criteria (T2TUV on day 1, n = 248; day 2-3, n = 172; no target rate UV, n = 369). In-hospital mortality in the day 1 group was significantly lower (2.7% vs. 5.9% vs. 11.1%; p < 0.001) than that of other groups. The mortality and re-hospitalization for 1 year in the day 1 group was significantly lower (event-free rate: 67.7% vs. 54.1% vs. 56.9%; log-lank p = 0.004) than that of other groups. In multivariate analysis, predictors of T2TUV at day 1 were age (odds ratio [OR]: 1.02, 95% confidence interval [CI]: 1.01-1.04, p = 0.007), previous hospitalized heart failure (OR: 1.47, 95% CI: [1.03-2.12], p = 0.03), N-terminal-pro B type natriuretic peptide per 1000 pg/ml (OR: 1.02, 95% CI: 1.01-1.04, p = 0.007), carperitide (OR: 0.69, 95% CI: 0.48-0.99, p = 0.05), and early administration of tolvaptan (OR: 0.6, 95% CI: 0.42-0.85, p = 0.004). CONCLUSIONS: T2TUV of less than day 1 was associated with lower in-hospital mortality and decreased mortality and re-hospitalization at 1 year.

Predictors of Poor Very Early Diuretic Response and Effectiveness of Early Tolvaptan in Symptomatic Acute Heart Failure.

BACKGROUND: Diuretic response (DR) in patients with symptomatic acute decompensated heart failure (ADHF) has an impact on prognosis. This study aimed to identify predictive factors influencing acute 6 h poor DR and to assess DR after early administration of tolvaptan (TLV). METHODS: This multicenter retrospective study included 1670 patients who were admitted for ADHF and received intravenous furosemide within 1 h of presentation in clinical scenario 1 or 2 defined based on initial systolic blood pressure ≥100 mmHg with severe symptoms (New York Heart Association class III or IV (n = 830). The score for the poor DR factors in the very acute phase was calculated in patients treated with furosemide-only diuretics (n = 439). The DR to TLV administration was also assessed in patients who received an additional dose of TLV within 6 h (n = 391). RESULTS: The time since discharge from the hospital for a previous heart failure < 3 months (odds ratio [OR] 2.78, 95% confidence interval [CI] 1.34-5.83; p = 0.006), loop diuretics at admission (OR 3.05, 95% CI 1.74-5.36; p < 0.0001), and estimated glomerular filtration rate (eGFR) < 45 mL/min/1.73 m2 (OR 2.99, 95% CI 1.58-5.74; p = 0.0007) were independent determinants of poor DR. The frequency of poor DR according to the risk stratification group was low risk (no risk factor), 18.9%; middle risk (one risk factor), 33.1%; and high risk (two to three risk factors), 58.0% (p < 0.0001). All risk groups demonstrated a significantly lower incidence of poor DR with early TLV administration: 10.7% in the early TLV group versus 18.9% in the loop diuretics group (p = 0.09) of the low-risk group; 18.4% versus 33.1% (p = 0.01) in the middle-risk group, and 20.2% versus 58.0% (p < 0.0001) in the high-risk group. CONCLUSION: Early administration of TLV in patients with predicted poor DR contributed to a significant diuretic effect and suppression of worsening renal function.

Differences in Intravascular Ultrasound Measurement Values Between Treatment Modalities for Restenosis in Femoropopliteal Lesions.

BACKGROUND: The risk of restenosis after intervention is higher in femoropopliteal than in aortoiliac lesions. However, the appropriate endovascular therapy (EVT) for preventing restenosis after intervention for femoropopliteal lesions remains unknown. This study aimed to elucidate the relationship between lesion characteristics and patency after EVT using intravascular ultrasound (IVUS) measurement and to determine the predictors of restenosis on IVUS.Methods and Results:This prospective observational study was performed at 18 Japanese centers. We evaluated the lesion characteristics before and after EVT for femoropopliteal lesion using IVUS. Angiographic or duplex ultrasound follow-up was performed at 1 year after EVT. A total of 263 lesions underwent EVT between December 2016 and December 2017. In total, 20 lesions (8 cases of isolated common femoral artery lesion and 12 cases of restenosis lesion) were excluded, and 243 lesions were enrolled in this study. A total of 181 lesions were treated with stent placement, and 62 lesions were treated only with balloon angioplasty. In the case of stent use, a larger distal plaque burden was associated with restenosis, while a lower calcification angle was associated with higher patency in the case of balloon angioplasty alone. CONCLUSIONS: The factors related to patency differed depending on the treating modality. The findings suggest that IVUS is a useful tool for predicting patency because it can provide a more accurate evaluation after EVT for femoropopliteal lesions.

The impact of percutaneous coronary intervention using the novel dynamic coronary roadmap system.

The dynamic coronary roadmap (DCR) is a novel technology that creates a dynamic, motion-compensated, real-time overlay of the coronary arteries on a fluoroscopic image. Whether the DCR reduces contrast volume and enables safe and effective treatment was examined. A total of 146 patients undergoing percutaneous coronary intervention (PCI) from June 2017 to September 2017 in our hospital were retrospectively evaluated. Chronic total occlusion lesions, acute coronary syndrome, and hemodialysis patients were excluded. Patients were divided into the control group (PCI without DCR, 92 patients, 103 lesions) and the DCR group (38 patients, 43 lesions). The primary endpoint was contrast medium volume, and secondary endpoints were radiation dose, fluoroscopy time, and clinical success rate. There was no significant difference in the success rate (100% vs. 100%, P = 1.000) between the groups. Fluoroscopy time (16.3 ± 11.2 min. vs. 11.4 ± 5.5 min, P = 0.007) and contrast medium volume (152.1 ± 73.0 ml vs. 118.8 ± 49.7 ml, P = 0.006) were significantly lower in the DCR group than in the control group. DCR use during PCI was associated with a significant reduction in contrast volume and fluoroscopy time compared to a control group despite similar clinical, lesion, and procedural characteristics.

Utility of indigo carmine angiography in patients with critical limb ischemia: Prospective multi-center intervention study (DIESEL-study).

OBJECTIVES: To assess the efficacy of indigo carmine angiography for wound healing after successful below-the-knee intervention in patients with critical limb ischemia (CLI). METHODS: A multi-center prospective intervention study was conducted. Fifty-four limbs of 53 patients in Rutherford categories 5 and 6 underwent endovascular therapy (EVT). After successful EVT, 5 mL of indigo carmine was injected through a catheter at the distal popliteal artery and color changes in the foot were evaluated. The results of indigo carmine angiography were divided into three groups: In type I, the color change of the wound was deeper than the surrounding tissue; in type II, the change in wound color was similar to the surrounding tissue; and in type III, no discoloration of the wound was observed by the indigo carmine. RESULTS: The wound healing rates at 3 months were 78% (25/32) for type I, 70% (7/10) for type II, and 42% (5/12) for type III (P for trend = 0.025). Indigo carmine angiography-related complications were not seen. CONCLUSION: Indigo carmine angiography was found to be a safe and useful procedure to provide visual information on foot perfusion. This dye coloring method demonstrated that after successful angioplasty, the perfused area was made visible at the microcirculation level. Indigo carmine angiography can thus be considered an important predictor for wound healing by EVT in patients with CLI.

Construction of a Heart Failure Database Collating Administrative Claims Data and Electronic Medical Record Data to Evaluate Risk Factors for In-Hospital Death and Prolonged Hospitalization.

Background: Clinical studies on heart failure (HF) using diagnosis procedure combination (DPC) databases have attracted attention recently, but data obtained from such databases may lack important information essential for determining the severity of HF. Methods and Results: Using a HF database that collates DPC data and electronic medical records from 3 hospitals in Japan, we investigated factors contributing to prolonged hospitalization and in-hospital death, based on clinical characteristics and data obtained early during hospitalization in 2,750 Japanese patients with HF hospitalized between 2011 and 2015. Mean age was 77.0±13.0 years; 55.3% (n=1,520) were men, and 39.1% (n=759) had left ventricular ejection fraction <40%. In-hospital mortality was 6.0% (n=164) and mean length of stay for patients who were discharged alive was 18.2±13.7 days (median, 15 days). Factors contributing to in-hospital death were advanced age, higher New York Heart Association (NYHA) class, low albumin and sodium, and high creatinine and C-reactive protein (CRP). Factors contributing to prolonged hospitalization were higher NYHA class, low Barthel index, low albumin, and high B-type natriuretic peptide, lactate dehydrogenase, and CRP. Conclusions: We have constructed a database of HF hospitalized patients in acute care hospitals in Japan. This approach may be helpful to address clinical parameters of HF patients in any acute care hospital in Japan.

A novel validated method for predicting the risk of re-hospitalization for worsening heart failure and the effectiveness of the diuretic upgrading therapy with tolvaptan.

Increased re-hospitalization due to acute decompensated heart failure (ADHF) is a modern issue in cardiology. The aim of this study was to investigate risk factors for re-hospitalization due to worsening heart failure, and the effect of tolvaptan (TLV) on decreasing the number of re-hospitalizations. This was a multicenter, retrospective study. The re-hospitalization factors for 1191 patients with ADHF were investigated; patients receiving continuous administration of TLV when they were discharged from the hospital (n = 194) were analyzed separately. Patients were classified into 5 risk groups based on their calculated Preventing Re-hospitalization with TOLvaptan (Pretol) score. The total number of patients re-hospitalized due to worsening heart failure up to one year after discharge from the hospital was 285 (23.9%). Age ≥80 years, duration since discharge from the hospital after previous heart failure <6 months, diabetes mellitus, hemoglobin <10 g/dl, uric acid >7.2 mg/dl, left ventricular ejection fraction (LVEF) <40%, left atrial volume index (LAVI) >44.7 ml/m2, loop diuretic dose ≥20 mg/day, hematocrit <31.6%, and estimated glomerular filtration rate (eGFR) <50 ml/min/1.73m2 were independent risk factors for re-hospitalization for worsening heart failure. There was a significant reduction in the re-hospitalization rate among TLV treated patients in the Risk 3 group and above. In conclusions, age, duration since previous heart failure, diabetes mellitus, hemoglobin, uric acid, LVEF, LAVI, loop diuretic dose, hematocrit, and eGFR were all independent risk factors for re-hospitalization for worsening heart failure. Long-term administration of TLV significantly decreases the rate of re-hospitalization for worsening heart failure in patients with a Pretol score of 7.

Efficacy and safety of a coagulated thrombus injection for peripheral artery perforation: The coagulated thrombus hemostasis method.

BACKGROUND: This retrospective study assesses the safety and efficacy of using a thrombus injection for treatment a peripheral artery perforation. METHODS AND RESULTS: From March 2013 to April 2016, we performed 1,152 endovascular treatment (EVT) at our hospital. Of these, 28 peripheral artery perforations occurred during the EVT procedure and 20 were treated with a thrombus, which we artificially created. The thrombus comprised the patient's blood and thrombin. It was injected into the perforation site from the tip of an over-the-wire balloon using ballooning method. The perforated arteries occurred in below-the-knee artery (45%), superficial femoral artery (35%), deep femoral artery (10%), popliteal artery (5%), and external iliac artery (5%). Thrombus injection was successful in 19 of the 20 perforations (95%). One patient required coil embolization. There were no complications during or after admission. CONCLUSIONS: Thrombus injection is a safety method and might be considered as one of the approaches for stopping peripheral artery perforation.

Total thoracoscopic left ventricular lead implantation for hybrid cardiac resynchronization therapy in pacemaker-mediated cardiomyopathy.

Cardiac resynchronization therapy (CRT) has been increasingly performed in patients having heart failure with dyssynchrony. We report a successful case of total thoracoscopic left ventricular (LV) lead implantation in CRT. A 77-year-old man with marked dyssynchrony of the LV wall motion and a low ejection fraction (EF17%) due to pacemaker-mediated cardiomyopathy was referred to us. CRT was planned, but percutaneous LV lead implantation proved difficult owing to anatomical variations. The LV lead was placed in the post-lateral wall of the LV base using a total thoracoscopic procedure. Preoperative dyspnea and dyssynchrony were clearly improved. In CRT, the LV wall stimulation site is important. The LV lead should be implanted in the latest activation area, which can be detected using speckle tracking echocardiography. Surgical lead implantation can be performed in the ideal area, and this procedure may play a new role as a hybrid CRT.

Clinical effects of single or double tibial artery revascularization in critical limb ischemia patients with tissue loss.

OBJECTIVE: The achievement of single vessel inflow to the wound is an acceptable end point of peripheral vascular intervention for patients with critical limb ischemia (CLI) with tissue loss. However, CLI patients often have multitibial artery lesions. We evaluated the clinical effects of single or double tibial artery revascularization for CLI patients. METHODS: This study was conducted retrospectively in a single center. Between April 2007 and January 2015, we treated 123 CLI patients (137 limbs) who had lesions in both the anterior tibial artery and the posterior tibial artery. Of these, single tibial artery (anterior or posterior tibial artery) revascularization was performed in 84 limbs (group S) and double tibial artery (both anterior and posterior tibial arteries) revascularization was performed in 53 limbs (group D). RESULTS: The wound healing rate was significantly higher (87% vs 79%; P = .003), the time to wound healing was shorter (median, 83 vs 142 days; P = .01), and the repeat peripheral vascular intervention rate was lower (15% vs 35%; P = .03) in group D than in group S. The wound healing rate was nearly similar between the 2 groups in patients with a low clinical stage as assessed by Society for Vascular Surgery Wound, Ischemia, and foot Infection (90% in group D vs 93% in group S; P = .20); however, the wound healing rate was significantly higher in group D in patients with a high clinical stage (85% vs 72%; P = .007). CONCLUSIONS: The achievement of double vessel inflows to the wound by double tibial artery revascularization positively affects wound healing, particularly in severe CLI patients.

Clinical Outcomes of the Intraluminal Approach for Long Occlusive Femoropopliteal Lesions Assessed by Intravascular Ultrasound.

AIM: To investigate the relationship between intravascular ultrasound (IVUS) findings and restenosis after stent implantation for long occlusive femoropopliteal (FP) lesions using the intraluminal approach. METHODS: This was a single-center retrospective study of 45 patients (49 lesions) with de novo long occlusive FP lesions treated with bare metal stents implanted using the intraluminal approach under IVUS guidance from April 2007 to December 2014. All patients were followed up at least 12 months. The preprocedural and postprocedural IVUS findings were compared for patients with and without restenosis, which was defined as a peak systolic velocity ratio of ＞2.4 on duplex ultrasonography or ＞50% diameter stenosis on angiography. RESULTS: Within 12 months, 13 patients (14 lesions) developed restenosis, whereas 32 patients (35 lesions) did not (restenosis rate=29%). The male: female ratio and the prevalence of diabetes mellitus, hemodialysis, and critical limb ischemia were similar between the two groups. No significant differences were observed in lesion length, chronic total occlusion (CTO) length, and the percentage of involving popliteal lesion between the two groups. A whole intraplaque route was gained in 15 lesions (31%). Multivariate analysis revealed that the within-CTO intramedial route proportion and the distal lumen cross-sectional area (CSA) were independent predictors of restenosis. Receiver operating characteristic analysis showed that the best cutoff values of these parameters were 14.4% and 17.7 mm2, respectively. CONCLUSIONS: In patients with long occlusive FP lesions undergoing stent placement using the intraluminal approach, a whole intraplaque route was gained in 31%. Restenosis is more likely if IVUS shows a within-CTO intramedial route proportion of ＞14.4% or distal lumen CSA of ＜17.7 mm2.

Incidence and clinical outcomes of the slow-flow phenomenon after infrapopliteal balloon angioplasty.

OBJECTIVE: This study investigated the incidence and clinical relevance of the slow-flow phenomenon after infrapopliteal balloon angioplasty. METHODS: This retrospective, single-center study included 161 consecutive patients with critical limb ischemia (173 limbs) who underwent endovascular treatment for infrapopliteal lesions between January 2012 and May 2015. The overall technical success rate was 88%. Of these lesions, 30 limbs presented with slow flow after angioplasty. RESULTS: Total occlusion (90% vs 63%; P < .01) and severe calcification (43% vs 8%; P < .01) were more common in the slow-flow group. Kaplan-Meier curve analysis revealed that freedom from major amputation (60% vs 86%; log-rank, P < .01) and wound healing at 2 years (77% vs 91%; log-rank, P = .03) were significantly less common in the slow-flow group. Univariate Cox proportional hazard analysis identified Rutherford class 6 (hazard ratio [HR], 6.4; 95% confidence interval [CI], 2.8-15.8; P < .01), the slow-flow phenomenon (HR, 3.9; 95% CI, 1.6-8.9; P < .01), and hemodialysis (HR, 3.2; 95% CI, 1.2-11.1; P = .02) as independent predictors of major amputation and Rutherford class 6 (HR, 0.3; 95% CI, 0.2-0.6; P < .01), the slow-flow phenomenon (HR, 0.5; 95% CI, 0.3-0.9; P = .02), and pedal arch (HR, 1.6; 95% CI, 1.0-2.5; P = .04) as predictors of wound healing. CONCLUSIONS: The slow-flow phenomenon after infrapopliteal balloon angioplasty occurred in 18.6% of limbs. This phenomenon may result in poor outcomes.

Wound healing of critical limb ischemia with tissue loss in patients on hemodialysis.

We assessed wound healing in patients on hemodialysis (HD) with critical limb ischemia (CLI). This study enrolled 267 patients (including 120 patients on HD and 147 patients not on HD) who underwent endovascular therapy (EVT) for CLI. The primary endpoint was wound-healing rate at two years. Secondary endpoints were time to wound healing, wound recurrence rate, and limb salvage at two years. The percentage of male and young patients was higher in the HD patients ( p < 0.01). A lower patency of the pedal arch after EVT was observed frequently in HD patients ( p < 0.01). The wound-healing rate was significantly lower in HD patients (79.5% vs. 92.4%, p < 0.001). Time to wound healing was significantly longer in HD patients (median 132 days vs. 82 days, p = 0.005). Wound recurrence was observed more frequently in HD patients (25.0% vs. 10.2%, p = 0.007). Limb salvage (72.8% vs. 86.4%, p = 0.002) was significantly lower in HD patients. In a cox proportional hazard model, HD was an independent predictor of wound healing (risk ratio (RR), 0.46; 95% confidence interval (CI), 0.33-0.62; p < 0.001) and wound recurrence (RR, 1.58; 95% CI, 1.11-2.22; p = 0.01). HD was independently associated with lower and delayed wound healing, and wound recurrence.

Frequency and predictors of bleeding events after 2nd generation drug-eluting stent implantation differ depending on time after implantation.

BACKGROUND: Antiplatelet therapy is required after drug-eluting stent (DES) implantation, but bleeding events occur unexpectedly. We aimed to assess whether bleeding event predictors after 2nd generation DES (2nd DES) implantation differed by time after implantation. METHODS: We studied 1912 consecutive patients who underwent successful 2nd DES implantation (70±10 years, 72% male). Bleeding events were recorded as early (≤1 year) and late (>1 year). Major bleeding events were defined as a composite of type 5, 3, and 2 bleeding in the Bleeding Academic Research Consortium criteria. Predictors were assessed using a Cox proportional hazard model. RESULTS: Bleeding event rates were 3.3%, 5.1%, and 6.7% at 1, 2, and 3 years, respectively, with the highest 1-year rate in year 1 (p<0.001). Cause and severity of bleeding events were similar between early and late bleeding events. Prior history of gastrointestinal bleeding, non-steroidal anti-inflammatory drug use, and triple antithrombotic therapy [adjusted risk ratio (RR): 3.68, 3.21, 4.57, respectively; p<0.01] were independent predictors of early bleeding events. Age >80 years and severe renal dysfunction (adjusted RR: 2.27, 2.02, respectively; p<0.01) were independent predictors of late bleeding events. Survival rate was significantly lower in patients with bleeding events compared with patients without bleeding events (82.4% vs 90.1%; p<0.001). CONCLUSION: Frequency and predictors of bleeding events after 2nd DES implantation differ by time after implantation. Treatment strategies corresponding to individual patients are required.

Ability of Fractional Flow Reserve to Predict Restenosis After Superficial Femoral Artery Stenting.

PURPOSE: To evaluate the clinical efficacy of poststenting fractional flow reserve (FFR) in terms of predicting restenosis in superficial femoral artery (SFA) disease. METHODS: This prospective, single-center, nonrandomized study enrolled 48 patients (mean age 76±9 years; 38 men) with 51 SFA lesions from July 2013 to June 2014. Mean FFR (distal mean pressure/proximal mean pressure) and systolic FFR (distal systolic pressure/proximal systolic pressure) were calculated, and the relationship between these FFR values and restenosis at 12 months was investigated using receiver operating characteristic (ROC) curve analysis. RESULTS: Poststenting FFR was significantly lower in the restenosis group (poststenting mean FFR 0.85±0.07 vs 0.93±0.05, p=0.001; poststenting systolic FFR 0.76±0.14 vs 0.87±0.08, p=0.015). The area under the ROC curve for restenosis in poststenting mean FFR was higher, but not statistically significant, than that in poststenting systolic FFR (0.84 vs 0.74, p=0.08). The best poststenting mean FFR cutoff value for predicting restenosis was 0.92 (sensitivity 0.64, specificity 0.91). The 4.5% restenosis rate at 12 months in the high (>0.92) poststenting mean FFR group was significantly lower (35.7%, p=0.008) than in the low (≤0.92) poststenting mean FFR group. CONCLUSION: Poststenting mean FFR is useful for predicting restenosis in SFA disease.

A new scoring system (DAIGA) for predicting bleeding complications in atrial fibrillation patients after drug-eluting stent implantation with triple antithrombotic therapy.

BACKGROUND: No scoring system for evaluating the bleeding risk of atrial fibrillation (AF) patients after drug-eluting stent (DES) implantation with triple antithrombotic therapy (TAT) is available. We aimed to develop a new scoring system for predicting bleeding complications in AF patients after DES implantation with TAT. METHODS AND RESULTS: Between April 2007 and April 2014, 227 AF patients undergoing DES implantation with TAT were enrolled. Bleeding incidence defined as Bleeding Academic Research Consortium criteria≥2 was investigated and predictors of bleeding complications were evaluated using multivariate analysis. Bleeding complications occurred in 58 patients (25.6%) during follow-up. Multivariate analysis revealed dual antiplatelet therapy (DAPT) continuation (OR 3.33, P=0.01), age>75 (OR 2.14, P=0.037), international normalized ratio>2.2 (OR 5.82, P<0.001), gastrointestinal ulcer history (OR 3.06, P=0.037), and anemia (OR 2.15, P=0.042) as predictors of major bleeding complications. A score was created using the weighted points proportional to the beta regression coefficient of each variable. The DAIGA score showed better predictive ability for bleeding complications than the HAS-BLED score (AUC: 0.79 vs. 0.62, P=0.0003). Bleeding incidence was well stratified: 17.8% in low-risk (scores 0-1), 55.5% in moderate-risk (2-3), and 83.0% in high-risk (4-7) patients (P<0.001). CONCLUSIONS: This scoring system is useful for predicting bleeding complications and risk stratification of AF patients after DES implantation with TAT.

Comparison of first- and second-generation drug-eluting stent efficacies for treating left main and/or three-vessel disease: a propensity matched study.

The efficacy of second-generation drug-eluting stent (DES) for the treatment of left main disease (LM) and/or three vessel disease (3VD) remains unclear. We compared 2-year outcomes of second- versus first -generation DES implantation among patients with LM and/or 3VD and to assess the differential of risk by complexity of coronary artery disease using synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) scores. Between April 2007 and December 2012, 341 patients with LM and/or 3VD were treated by percutaneous coronary intervention; 154 with first-generation DES and 137 with second-generation DES. After propensity matching, 101 patients remained in each group. The rate of target lesion revascularization (TLR) and major adverse cardiac event (MACE) were compared. TLR and MACE at 2 years were more common in the first- compared with second-generation DES group (TLR 19.8 vs. 8.9 %; p = 0.016, MACE 24.8 vs. 10.9 %; p = 0.008). In patients with low (0-22) and intermediate (23-32) SYNTAX scores, TLR and MACE tended to occur more often with first-generation DES group. In patients with high SYNTAX scores (≧33), TLR and MACE were significantly more common with first-generation DES group (TLR 29.0 vs. 11.1 %; p = 0.035, MACE 35.5 vs. 13.9 %; p = 0.034). Compared with first-generation DES, second-generation DES proved beneficial in reducing risk of TLR and MACE in patients with LM and/or 3VD, particularly among those with high SYNTAX scores (≧33).
