Endovascular therapy is strongly recommended for acute cerebral large vessel occlusion (LVO) with an Alberta stroke program early computed tomography score (ASPECTS) ≥6 due to occlusion of the internal carotid artery or M1 segment of the middle cerebral artery. However, the effect of endovascular therapy for patients with a large ischemic core with an ASPECTS ≤5 (0–5) was not established. A multicenter, randomized, open-label, parallel-group trial was conducted to investigate the superiority of endovascular therapy over medical therapy without endovascular therapy for a large ischemic core with ASPECTS (3–5). Patients were randomly assigned to receive endovascular therapy or without endovascular therapy at a ratio of 1:1. The primary outcome was a moderate functional outcome, defined as a modified Rankin scale (mRS; scores ranging from 0 [no symptoms] to 6 [death]) ≤3 after 90 days. The secondary outcomes were defined as ordinal mRS, good functional outcome (mRS ≤2), excellent functional outcome (mRS ≤1), mRS shift analysis after 90 days, and early improvement of neurological findings at 48 hours. A total sample size of 200 was estimated to provide a power of 0.9 with a two-sided alpha of 0.05, for the primary outcome, considering a 15% dropout rate. This randomized clinical trial reported the applicability of endovascular therapy in patients with acute cerebral LVO with a large ischemic core.

Background: There is a paucity of data on the effect of optimal intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) compared with standard PCI or coronary artery bypass grafting (CABG) in patients with multivessel disease.Methods and Results: The OPTIVUS-Complex PCI study multivessel cohort was a prospective multicenter single-arm study enrolling 1,021 patients undergoing multivessel PCI including the left anterior descending coronary artery using IVUS aiming to meet the prespecified criteria for optimal stent expansion. We conducted propensity score matching analyses between the OPTIVUS group and historical PCI or CABG control groups from the CREDO-Kyoto registry cohort-3 (1,565 and 899 patients) fulfilling the inclusion criteria for this study. The primary endpoint was a composite of death, myocardial infarction, stroke, or any coronary revascularization. In the propensity score-matched cohort (OPTIVUS vs. historical PCI control: 926 patients in each group; OPTIVUS vs. historical CABG control: 436 patients in each group), the cumulative 1-year incidence of the primary endpoint was significantly lower in the OPTIVUS group than in the historical PCI control group (10.4% vs. 23.3%; log-rank P<0.001) or the historical CABG control group (11.8% vs. 16.5%; log-rank P=0.02).Conclusions: IVUS-guided PCI targeting the OPTIVUS criteria combined with contemporary clinical practice was associated with superior clinical outcomes at 1 year compared with not only the historical PCI control, but also the historical CABG control.

Background:There is a paucity of data on the management and prognosis of cancer-associated venous thromboembolism (VTE), leading to uncertainty about optimal management strategies.Methods and Results:The COMMAND VTE Registry is a multicenter registry enrolling 3,027 consecutive acute symptomatic VTE patients in Japan between 2010 and 2014. We divided the entire cohort into 3 groups: active cancer (n=695, 23%), history of cancer (n=243, 8%), and no history of cancer (n=2089, 69%). The rate of anticoagulation discontinuation was higher in patients with active cancer (43.5%, 27.0%, and 27.0%, respectively, at 1 year, P<0.001). The cumulative 5-year incidences of recurrent VTE, major bleeding, and all-cause death were higher in patients with active cancer (recurrent VTE: 17.7%, 10.2%, and 8.6%, P<0.001; major bleeding: 26.6%, 8.8%, and 9.3%, P<0.001; all-cause death: 73.1%, 28.6%, 14.6%, P<0.001). Among the 4 groups classified according to active cancer status, the cumulative 1-year incidence of recurrent VTE was higher in the metastasis group (terminal stage group: 6.4%, metastasis group: 22.1%, under chemotherapy group: 10.8%, and other group: 5.8%, P<0.001).Conclusions:In a current real-world VTE registry, patients with active cancer had higher risk for VTE recurrence, bleeding, and death, with variations according to cancer status, than patients without active cancer. Anticoagulation therapy was frequently discontinued prematurely in patients with active cancer in discordance with current guideline recommendations.

Background: The REAL-CAD trial, reported in 2017, demonstrated a significant reduction in cardiovascular events with high-intensity statins in patients with chronic coronary syndrome. However, data are scarce on the use of high-intensity statins in Japanese patients with acute coronary syndrome (ACS).Methods and Results: In STOPDAPT-2 ACS, which exclusively enrolled ACS patients between March 2018 and June 2020, 1,321 (44.2%) patients received high-intensity statins at discharge, whereas of the remaining 1,667 patients, 96.0% were treated with low-dose statins. High-intensity statins were defined as the maximum approved doses of strong statins in Japan. The incidence of the cardiovascular composite endpoint (cardiovascular death, myocardial infarction, definite stent thrombosis, stroke) was significantly lower in patients with than without high-intensity statins (1.44% vs. 2.69% [log-rank P=0.025]; adjusted hazard ratio [aHR] 0.48, 95% confidence interval [CI] 0.24–0.94, P=0.03) and the effect was evident beyond 60 days after the index percutaneous coronary intervention (log-rank P=0.01; aHR 0.38, 95% CI 0.17–0.86, P=0.02). As for the bleeding endpoint, there was no significant difference between the 2 groups (0.99% vs. 0.73% [log-rank P=0.43]; aHR 0.96, 95% CI 0.35–2.60, P=0.93).Conclusions: The prevalence of high-intensity statins has increased substantially in Japan. The use of the higher doses of statins in ACS patients recommended in the guidelines was associated with a significantly lower risk of the primary cardiovascular composite endpoint compared with lower-dose statins.

Background:We sought to explore the effects of previous heart failure (HF) hospitalization on mortality in patients hospitalized for acute decompensated HF (ADHF) in a large Japanese contemporary observational database.Methods and Results:We prospectively enrolled consecutive patients with ADHF in 19 participating hospitals between October 2014 and March 2016. Of 4,056 patients, 1,442 patients (35.4%) had at least 1 previous HF hospitalization (previous hospitalization group), while 2,614 patients (64.5%) did not have a history of HF hospitalization (de novo hospitalization group). Patients with previous hospitalization were older and more often had comorbidities such as anemia, and renal failure than those without. The cumulative 1-year incidence of all-cause death was significantly higher in the previous hospitalization group than in the de novo hospitalization group (28% vs. 19%, P<0.001). After adjusting confounders, the excess risk of the previous hospitalization group relative to the de novo hospitalization group for all-cause death remained significant (HR, 1.28; 95% CI: 1.10–1.50, P=0.001). The excess risk was significant in patients without advanced age, anemia, or renal failure, but not significant in patients with these comorbidities, with significant interaction. Increase in the number of hospitalizations was associated with an increased risk for mortality.Conclusions:In a contemporary ADHF cohort in Japan, repeated hospitalization was associated with an increasing, higher risk for 1-year mortality.

Background: Catheter ablation (CA) for atrial fibrillation (AF) in patients on hemodialysis (HD) is reported to have a high risk of late recurrence (LR). However, the relationship between early recurrence (ER) within a 90-day blanking period after CA in AF patients and LR in HD patients remains unclear.Methods and Results: Of the 5,010 patients in the Kansai Plus Atrial Fibrillation Registry, 5,009 were included in the present study. Of these patients, 4,942 were not on HD (non-HD group) and 67 were on HD (HD group). HD was an independent risk factor for LR after the initial CA (adjusted hazard ratio 1.6; 95% confidence interval 1.1–2.2; P=0.01). In patients with ER, the rate of sinus rhythm maintenance at 3 years after the initial CA was significantly lower in the HD than non-HD group (11.4% vs. 35.4%, respectively; log-rank P=0.004). However, in patients without ER, there was no significant difference in the rate of sinus rhythm maintenance at 3 years between the HD and non-HD groups (67.7% vs. 74.5%, respectively; log-rank P=0.62).Conclusions: ER in HD patients was a strong risk factor for LR. However, even HD patients could expect a good outcome without ER after the initial CA.

Background: Previous studies have reported that high-dose strong statin therapy reduces the incidence of contrast-induced nephropathy (CIN) in statin naïve patients; however, the efficacy of high-dose strong statins for preventing CIN in real-world clinical practice remains unclear. The aim of this study was to evaluate the efficacy of strong statin therapy in addition to fluid hydration for preventing CIN after cardiovascular catheterization.Methods and Results: This prospective, multicenter, randomized controlled trial included 420 patients with chronic kidney disease who underwent cardiovascular catheterization. They were assigned to receive high-dose pitavastatin (4 mg/day × 4 days) on the day before and of the procedure and 2 days after the procedure (Statin group, n=213) or no pitavastatin (Control group, n=207). Isotonic saline hydration combined with a single bolus of sodium bicarbonate (20 mEq) was scheduled for administration to all patients. In the control group, statin therapy was continued at the same dose as that before randomization. CIN was defined as a ≥0.5 mg/dL increase in serum creatinine or ≥25% above baseline at 48 h after contrast exposure. Before randomization, 83% of study participants were receiving statin treatment. The statin group had a higher incidence of CIN than the control group (3.0% vs. 0%, P=0.01). The 12-month rate of major adverse cardiovascular events was similar between the 2 groups.Conclusions: High-dose pitavastatin increases the incidence of CIN in this study population.

Background: There is scarce data evaluating the current practice pattern and clinical outcomes for patients with severe aortic stenosis (AS), including both those who underwent surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) and those who were managed conservatively in the TAVI era.Methods and Results: The Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis (CURRENT AS) Registry-2 is a prospective, physician-initiated, multicenter registry enrolling consecutive patients who were diagnosed with severe AS between April 2018 and December 2020 among 21 centers in Japan. The rationale for the prospective enrollment was to standardize the assessment of symptomatic status, echocardiographic evaluation, and other recommended diagnostic examinations such as computed tomography and measurement of B-type natriuretic peptide. Moreover, the schedule of clinical and echocardiographic follow up was prospectively defined and strongly recommended for patients who were managed conservatively. The entire study population consisted of 3,394 patients (mean age: 81.6 years and women: 60%). Etiology of AS was degenerative in 90% of patients. AS-related symptoms were present in 60% of patients; these were most often heart failure symptoms. The prevalence of high- and low-gradient AS was 58% and 42%, respectively, with classical and paradoxical low-flow low-gradient AS in 4.5% and 6.7%, respectively.Conclusions: The CURRENT AS Registry-2 might be large and meticulous enough to determine the appropriate timing of intervention for patients with severe AS in contemporary clinical practice.

Background:The effect of diabetes mellitus (DM) status on the long-term risk for heart failure (HF) in patients undergoing coronary revascularization has not been adequately evaluated.Methods and Results:In this study, 15,231 patients who underwent coronary revascularization in the CREDO-Kyoto Registry Cohort-2 were divided into 2 groups according to DM status (DM group: n=5,999; Non-DM group: n=9,232). The DM group was further divided into 2 groups according to insulin treatment (insulin-treated DM [ITDM]: n=1,353; non-insulin-treated DM [NITDM]: n=4,646). The primary outcome measure was HF hospitalization. The cumulative 5-year incidence of HF hospitalization was significantly higher in the DM than non-DM group (11.0% vs. 6.6%, respectively; log-rank P<0.0001), and in the ITDM than NITDM group (14.6% vs. 10.0%, respectively; log-rank P<0.0001). After adjusting for confounders, the increased risk of HF hospitalization with DM relative to non-DM remained significant (hazard ratio [HR] 1.47, 95% confidence interval [CI] 1.30–1.67, P<0.0001), whereas the risk associated with ITDM relative to NITDM was not significant (HR 1.17, 95% CI 0.96–1.43, P=0.12).Conclusions:The adjusted long-term risk for HF hospitalization after coronary revascularization was significantly higher in DM than non-DM patients, regardless of revascularization strategy, but did not differ between ITDM and NITDM patients.

Background:Exercise loading is contraindicated for patients with severe aortic stenosis (AS); however, everyday activities mandate the inclusion of a light load. The aim of this study was to investigate the efficacy and safety of exercise training for patients with severe AS who were admitted to a rehabilitation ward because of physical disability.Methods and Results:This historical cohort study was conducted at a single rehabilitation center in Japan. Patients admitted for rehabilitation of physical disability and those who met the definition of severe AS were analyzed. An exercise training program was implemented for patients with disability and severe AS. Cardiovascular symptoms during hospitalization were evaluated. Improvements in the performance of activities of daily living were assessed using the Functional Independence Measure (FIM). Eighteen patients undertook an exercise training program. The median patient age was 87 years (range 76–95 years). Of these patients, 3 died and another 3 were transferred to another hospital due to causes other than the exercise training program. None of the other patients experienced cardiovascular symptoms, and the FIM scores of 12 patients were significantly improved (median [range] scores at admission and discharge of 63 [32–88] and 87 [51–104], respectively; P<0.001).Conclusions:An exercise training program could be applied to patients with severe AS who were admitted for convalescent rehabilitation, because it can improve FIM scores.

Background:Patients with cancer-associated venous thromboembolism (VTE) are at high risk for recurrent VTE and are recommended to receive prolonged anticoagulation therapy if they are at a low risk for bleeding. However, there are no established risk factors for bleeding during anticoagulation therapy.Methods and Results:The COMMAND VTE Registry is a multicenter retrospective registry enrolling 3,027 consecutive patients with acute symptomatic VTE among 29 Japanese centers. The present study population consisted of 592 cancer-associated VTE patients with anticoagulation therapy. We constructed a multivariable Cox proportional hazard model to estimate the hazard ratio (HR) and 95% confidence interval (CI) of the potential risk factors for major bleeding. During a median follow-up period of 199 days, major bleeding occurred in 72 patients. The cumulative incidence of major bleeding was 5.8% at 3 months, 13.8% at 1 year, 17.5% at 2 years, and 28.1% at 5 years. The most frequent major bleeding site was gastrointestinal tract (47%). Terminal cancer (adjusted HR, 4.17; 95% CI, 2.22–7.85, P<0.001), chronic kidney disease (adjusted HR, 1.89; 95% CI 1.06–3.37, P=0.031), and gastrointestinal cancer (adjusted HR, 1.78; 95% CI, 1.04–3.04, P=0.037) were independently associated with an increased risk of major bleeding.Conclusions:Major bleeding events were common during anticoagulation therapy in real-world cancer-associated VTE patients. Terminal cancer, chronic kidney disease, and gastrointestinal cancer were the independent risk factors for major bleeding.

Background:Patients with severe aortic stenosis (AS) might be at high risk for adverse cardiovascular events at the time of non-cardiac surgery.Methods and Results:The current study population included 348 patients who underwent elective non-cardiac surgery under general or spinal anesthesia during the follow up of 3,815 patients in the CURRENT AS (Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis) registry. There were 187 patients with untreated severe AS at time of surgery (untreated severe AS group) and 161 patients who had undergone aortic valve replacement (AVR) before surgery (prior AVR group), including 23 patients with prophylactic AVR. The primary outcome measure was 30-day mortality after non-cardiac surgery. At 30 days after non-cardiac surgery, 8 patients (4.3%) died in the untreated severe AS group, while no patients died in the prior AVR group (P=0.008). The causes of death were cardiovascular in 6 out of 8 patients. Mortality at 30 days was higher in untreated severe AS patients with AS-related symptoms before surgery than in those without AS-related symptoms (7.2% vs. 3.1%). Higher surgical risk estimates of the non-cardiac surgery incrementally increased the risk of 30-day mortality in patients with untreated severe AS, though the difference was not statistically significant (low-risk: 0%, intermediate-risk: 4.3%, and high-risk: 6.6 %, P=0.46).Conclusions:Symptomatic and asymptomatic severe AS might be associated with higher risk of 30-day mortality if untreated before elective intermediate- and high-risk non-cardiac surgery, while no patient with prior AVR died after elective non-cardiac surgery.

Background:There are no data comparing transcatheter aortic valve implantation (TAVI) with surgical aortic valve replacement (SAVR) outcomes in real clinical practice in Japan.Methods and Results:We combined 2 independent registries, the K-TAVI Registry (a 6-center prospective registry of consecutive patients who underwent TAVI) and the CURRENT AS Registry (a large, 27-center registry of 3,815 consecutive patients with severe aortic stenosis [AS]). In the K-TAVI Registry, 338 patients underwent TAVI with SAPIEN XT balloon-expandable valves from October 2013 to January 2016, whereas in the CURRENT AS Registry 237 patients with severe AS underwent SAVR from January 2003 to December 2011. Propensity score matching was conducted, with final cohort comprising 306 patients. The cumulative 2-year incidence of all-cause death and heart failure (HF) hospitalization did not differ significantly between the TAVI and SAVR groups (13.7% vs. 12.4% [P=0.81] and 7.9% vs 3.9% [P=0.13], respectively). After adjusting for residual confounders, there were no significant differences between the TAVI and SAVR groups in the risk for all-cause death (hazard ratio [HR] 0.74; 95% confidence interval [CI] 0.35–1.58; P=0.43) or HF hospitalization (HR 1.27; 95% CI 0.40–4.59; P=0.69).Conclusions:These findings from 2 independent Japanese registries suggest that the 2-year risk of all-cause mortality and HF does not differ significantly between TAVI and SAVR groups in real-world practice in Japan.

Background:Inter-facility transfer for primary percutaneous coronary intervention (PCI) from referring facilities to PCI centers causes a significant delay in treatment of ST-segment elevation acute myocardial infarction (STEMI) patients undergoing primary PCI. However, little is known about the clinical outcomes of STEMI patients undergoing inter-facility transfer in Japan.Methods and Results:In the CREDO-Kyoto acute myocardial infarction (AMI) registry that enrolled 5,429 consecutive AMI patients in 26 centers in Japan, the current study population consisted of 3,820 STEMI patients who underwent primary PCI within 24 h of symptom onset. We compared long-term clinical outcomes between inter-facility transfer patients and those directly admitted to PCI centers. The primary outcome measure was a composite of all-cause death or heart failure (HF) hospitalization. There were 1,725 (45.2%) inter-facility transfer patients, and 2,095 patients (54.8%) with direct admission to PCI centers. The cumulative 5-year incidence of death/HF hospitalization was significantly higher in the inter-facility transfer patients than in those with direct admission (26.9% vs. 22.2%; log-rank P<0.001). After adjusting for potential confounders, the risk for death/HF hospitalization was significantly higher (adjusted hazard ratio: 1.22, 95% confidence interval: 1.07–1.40, P<0.001) in the inter-facility transfer patients than in those directly admitted.Conclusions:Inter-facility transfer was associated with significantly worse long-term clinical outcomes for patients with STEMI undergoing primary PCI.

Background:In the setting of elective percutaneous coronary intervention (PCI), intravascular ultrasound (IVUS)-guided PCI is associated with a reduction in the incidence of target vessel revascularization (TVR), but the impact of IVUS on long-term clinical outcome in the setting of emergency PCI for ST-segment elevation acute myocardial infarction (STEMI) is still unclear.Methods and Results:The subjects consisted of 3,028 STEMI patients who underwent primary PCI within 24 h of symptom onset in the CREDO-Kyoto acute myocardial infarction registry. Of these, 932 patients (31%) underwent IVUS-guided PCI. Compared with the angiography-guided PCI without IVUS, IVUS-guided PCI was associated with significantly lower incidences of TVR (primary outcome measure; 22% vs. 27%, log-rank P<0.001) and definite stent thrombosis (ST; 1.2% vs. 3.1%, log-rank P=0.003). The cumulative incidence of all-cause death was not significantly different between the 2 groups. After adjusting for confounders, however, there were no significant differences between the 2 groups in risk for TVR (adjusted HR, 1.14; 95% CI: 0.86–1.51, P=0.38) and definite ST (adjusted HR, 0.58; 95% CI: 0.19–1.72, P=0.33).Conclusions:IVUS-guided PCI was not associated with a lower risk for TVR or ST in STEMI patients undergoing primary PCI.

Background: The clinical benefits of neurohormonal antagonists for patients with heart failure (HF) with mid-range and preserved ejection fraction (HFmrEF and HFpEF) are uncertain.Methods and Results: This study analyzed 858 consecutive patients with HFmrEF (EF: 40–49%) or HFpEF (EF ≥50%), who were hospitalized for acute HF, and who were discharged alive, and were not taking angiotensin-converting enzyme inhibitors (ACE)-I/ angiotensin II receptor blockers (ARB) or β-blockers at admission. The study population was classified into 4 groups according to the status of prescription of ACE-I/ARB and β-blocker at discharge: no neurohormonal antagonist (n=342, 39.9%), ACE-I/ARB only (n=128, 14.9%), β-blocker only (n=189, 22.0%), and both ACE-I/ARB and β-blocker (n=199, 23.2%) groups. The primary outcome measure was a composite of all-cause death or HF hospitalization. The cumulative 1-year incidence of the primary outcome measure was 41.2% in the no neurohormonal antagonist group, 34.0% in the ACE-I/ARB only group, 28.6% in the β-blocker only group, and 16.4% in the both ACE-I/ARB and β-blocker group (P<0.001). Compared with the no neurohormonal antagonist group, both the ACE-I/ARB and β-blocker groups were associated with a significantly lower risk for a composite of all-cause death or HF hospitalization (HR: 0.46, 95% CI: 0.28–0.76, P=0.002).Conclusions: In hospitalized patients with HFmrEF and HFpEF, starting both ACE-I/ARB and a β-blocker was associated with a reduced risk of the composite of all-cause death or HF hospitalization compared with patients not starting on an ACE-I/ARB or β-blocker.

Background: The relationship between very low on-treatment low-density lipoprotein cholesterol (LDL-C) level and cardiovascular event risk is still unclear in patients receiving the same doses of statins.Methods and Results: From the REAL-CAD study comparing high-dose (4 mg/day) with low-dose (1 mg/day) pitavastatin therapy in patients with stable coronary artery disease, 11,105 patients with acceptable statin adherence were divided into 3 groups according to the on-treatment LDL-C level at 6 months (<70 mg/dL, 70–100 mg/dL, and ≥100 mg/dL). The primary outcome measure was a composite of cardiovascular death, non-fatal myocardial infarction, non-fatal ischemic stroke, or unstable angina requiring emergent admission. The adjusted risks of the LDL-C <70 mg/dL group relative to the LDL-C 70–100 mg/dL group (reference) was not significantly different for the primary outcome measure in both 1 mg/day and 4 mg/day strata (HR 0.84, 95% CI 0.58–1.18, P=0.32, and HR 1.25, 95% CI 0.88–1.79, P=0.22). The adjusted risk of the LDL-C ≥100 mg/dL group relative to the reference group was not significant for the primary outcome measure in the 1 mg/day stratum (HR 0.82, 95% CI 0.60–1.11, P=0.21), whereas it was highly significant in the 4 mg/day stratum (HR 3.32, 95% CI 2.08–5.17, P<0.001).Conclusions: A very low on-treatment LDL-C level (<70 mg/dL) was not associated with lower cardiovascular event risk compared with moderately low on-treatment LDL-C level (70–100 mg/dL) in patients receiving the same doses of statins.

Background:The clinical significance of concomitant mitral regurgitation (MR) has not been well addressed in patients with severe aortic stenosis (AS).Methods and Results:We analyzed 3,815 patients from a retrospective multicenter registry of severe AS in Japan (CURRENT AS registry). We compared the clinical outcomes between patients with moderate/severe MR and with none/mild MR according to the initial treatment strategy (initial aortic valve replacement [AVR] or conservative strategy). The primary outcome measure was a composite of aortic valve-related death or heart failure hospitalization. At baseline, moderate/severe MR was present in 227/1,197 (19%) patients with initial AVR strategy and in 536/2,618 (20%) patients with a conservative strategy. The crude cumulative 5-year incidence of the primary outcome measure was significantly higher in patients with moderate/severe MR than in those with none/mild MR, regardless of the initial treatment strategy (25.2% vs. 14.4%, P<0.001 in the initial AVR strategy, and 63.3% vs. 40.7%, P<0.001 in the conservative strategy). After adjusting confounders, moderate/severe MR was not independently associated with higher risk for the primary outcome measure in the initial AVR strategy (hazard ratio [HR] 1.11, 95% confidence interval [CI] 0.67–1.83, P=0.69), and in the conservative strategy (HR 1.13, 95% CI 0.93–1.37, P=0.22).Conclusions:Concomitant moderate/severe MR was not independently associated with higher risk for the primary outcome measure regardless of the initial treatment strategy.

Background:Optimal intensity is unclear for P2Y12receptor blocker therapy after percutaneous coronary intervention (PCI) in real-world clinical practice.Methods and Results:From the CREDO-Kyoto Registry, the current study population consisted of 25,419 patients (Cohort-2: n=12,161 and Cohort-3: n=13,258) who underwent their first PCI. P2Y12receptor blocker therapies were reduced dose of ticlopidine (200 mg/day), and global dose of clopidogrel (75 mg/day) in 87.7% and 94.8% of patients in Cohort-2 and Cohort-3, respectively. Cumulative 3-year incidence of GUSTO moderate/severe bleeding was significantly higher in Cohort-3 than in Cohort-2 (12.1% and 9.0%, P<0.0001). After adjusting 17 demographic factors and 9 management factors potentially related to the bleeding events other than the type of P2Y12receptor blocker, the higher bleeding risk in Cohort-3 relative to Cohort-2 remained significant (hazard ratio (HR): 1.52 95% confidence interval (CI) 1.37–1.68, P<0.0001). Cohort-3 compared with Cohort-2 was not associated with lower adjusted risk for myocardial infarction/ischemic stroke (HR: 0.96, 95% CI: 0.87–1.06, P=0.44).Conclusions:In this historical comparative study, Cohort-3 compared with Cohort-2 was associated with excess bleeding risk, which might be at least partly explained by the difference in P2Y12receptor blockers.
