1 | Incidence and Determinants of Complications in Rotational Atherectomy: Insights From the National Clinical Data (J-PCI Registry) [20] | Sakakura K, Inohara T, Kohsaka S, Amano T, Uemura S, Ishii H, Kadota K, Nakamura M, Funayama H, Fujita H, Momomura SI | Circ Cardiovasc Interv. 2016 Nov;9 (11). pii: e004278 | The reported incidence of rotational atherectomy procedure-related complication rate was 1.3%, with each component ranging between 0.2 and 0.6%. Age, impaired kidney function, and previous myocardial infarction, emergent procedures, number of diseased vessels, and low institutional volume of radial access intervention were associated with higher complication rates |
2 | Relation of ST-Segment Elevation Myocardial Infarction to Daily Ambient Temperature and Air Pollutant Levels in a Japanese Nationwide Percutaneous Coronary Intervention Registry [9] | Yamaji K, Kohsaka S, Morimoto T, Fujii K, Amano T, Uemura S, Akasaka T, Kadota K, Nakamura M, Kimura T; J-PCI Registry Investigators | Am J Cardiol. 2017 Mar 15;119(6):872–880 | Absolute value and relative change in the ambient temperature were associated with the occurrence of STEMI; the associations with the air pollutant levels were less clear after adjustment for these meteorologic variables in this nationwide database |
3 | Impact of Institutional and Operator Volume on Short-Term Outcomes of Percutaneous Coronary Intervention: A Report From the Japanese Nationwide Registry [10] | Inohara T, Kohsaka S, Yamaji K, Amano T, Fujii K, Oda H, Uemura S, Kadota K, Miyata H, Nakamura M; J-PCI Registry Investigators | JACC Cardiovasc Interv. 2017 May 8;10(9):918–927 | In contemporary Japanese PCI practice, lower institutional volume (< 150 PCIs/year) was related inversely to in-hospital outcomes, but the association of annual operator volume with outcomes was less clear |
4 | Comparison of Outcomes of Women Versus Men With Non-ST-elevation Acute Coronary Syndromes Undergoing Percutaneous Coronary Intervention (from the Japanese Nationwide Registry) [21] | Numasawa Y, Inohara T, Ishii H, Kuno T, Kodaira M, Kohsaka S, Fujii K, Uemura S, Amano T, Kadota K, Nakamura M | Am J Cardiol. 2017;119(6):826–831 | In patients with non-ST-elevation acute coronary syndrome who underwent PCI, women were at greater risk than men for in-hospital complications, especially in bleeding complications |
5 | Comparison of Outcomes After Percutaneous Coronary Intervention in Elderly Patients, Including 10628 Nonagenarians: Insights From a Japanese Nationwide Registry (J-PCI Registry) [11] | Numasawa Y, Inohara T, Ishii H, Yamaji K, Kohsaka S, Sawano M, Kodaira M, Uemura S, Kadota K, Amano T, Nakamura M; J-PCI Registry Investigators | J Am Heart Assoc. 2019 Mar 5;8(5):e011183 | Older patients, especially nonagenarians [10 628 patients (1.9%) of all PCI patients}, carried a greater risk of in-hospital death and bleeding compared with younger patients after PCI. Transradial intervention might contribute to risk reduction for periprocedural complications in elderly patients undergoing PCI |
6 | In-Hospital Outcomes After Percutaneous Coronary Intervention for Acute Coronary Syndrome With Cardiogenic Shock (from a Japanese Nationwide Registry [J-PCI Registry]) [12] | Kubo S, Yamaji K, Inohara T, Kohsaka S, Tanaka H, Ishii H, Uemura S, Amano T, Nakamura M, Kadota K | Am J Cardiol. 2019 May 15;123 (10):1595-1601 | In-hospital mortality was 13.2% in ACS patients with cardiogenic shock who underwent contemporary PCI. Lower institutional PCI volumes, and concurrent bleeding were associated with higher in-hospital mortality |
7 | Risk stratification model for in-hospital death in patients undergoing percutaneous coronary intervention: a nationwide retrospective cohort study in Japan [13] | Inohara T, Kohsaka S, Yamaji K, Ishii H, Amano T, Uemura S, Kadota K, Kumamaru H, Miyata H, Nakamura M | BMJ Open. 2019 May 22;9(5):e026683 | We developed and validated a risk model predicting in-hospital mortality in a broad spectrum of Japanese patients after PCI. The risk model performed well in the entire validation cohort and among prespecified subgroups with good calibration, although both models underestimated the risk of mortality in high-risk patients with the elective procedure |
8 | An overview of percutaneous coronary intervention in dialysis patients: Insights from a Japanese nationwide registry [14] | Numasawa Y, Inohara T, Ishii H, Yamaji K, Hirano K, Kohsaka S, Sawano M, Kuno T, Kodaira M, Uemura S, Kadota K, Amano T, Nakamura M; J-PCI Registry Investigators | Catheter Cardiovasc Interv. 2019 Jul 1;94 [1]:E1–E8 | PCI was widely performed for dialysis patients with either ACS or non-ACS in Japan. Dialysis patients had a greater risk of adverse outcomes compared to nondialysis patients after PCI |
9 | Post-interventional adverse event risk by vascular access site among patients with acute coronary syndrome in Japan: observational analysis with a national registry J-PCI database [15] | Fujii T, Ikari Y, Hashimoto H, Kadota K, Amano T, Uemura S, Takashima H, Nakamura M; J-PCI Investigators | Cardiovasc Interv Ther. 2019 Oct;34 [4]:297–304 | Radial access was related to a significantly lower risk for access site bleeding compared with femoral access, even without strong antithrombotic drugs for ACS in Japan, and may also relate to lower risk for a wider set of post-treatment adverse events |
10 | Impact of Reduced-Dose Prasugrel vs. Standard-Dose Clopidogrel on In-Hospital Outcomes of Percutaneous Coronary Intervention in 62,737 Patients with Acute Coronary Syndromes: A Nationwide Registry Study in Japan [16] | Akita K, Inohara T, Yamaji K, Kohsaka S, Numasawa Y, Ishii H, Amano T, Kadota K, Nakamura M, Maekawa Y | Eur Heart J Cardiovasc Pharmacother. 2019 Oct 8 | In Japanese ACS patients undergoing PCI, the risk of bleeding was higher when using reduced-dose prasugrel than when using standard-dose clopidogrel, but there is no significant difference in in-hospital mortality and incidence of stent thrombosis between the two antiplatelet regimens |
11 | Diabetes mellitus and other cardiovascular risk factors in lower-extremity peripheral artery disease versus coronary artery disease: an analysis of 1,121,359 cases from the nationwide databases [17] | Takahara M, Iida O, Kohsaka S, Soga Y, Fujihara M, Shinke T, Amano T, Ikari Y; J-EVT and J-PCI investigators | Cardiovasc Diabetol. 2019 Nov 15;18 [1]:155 | Patient profiles were not identical but rather considerably different between clinically significant lower-extremity peripheral artery disease and coronary artery disease patients warranting revascularization. Of note, the prevalence of diabetes mellitus and end-stage renal disease was 1.96- and 6.39-times higher in LE-PAD patients than in CAD patients |
12 | Presentation Pattern of Lower Extremity Endovascular Intervention versus Percutaneous Coronary Intervention [18] | Takahara M, Iida O, Kohsaka S, Soga Y, Fujihara M, Shinke T, Amano T, Ikari Y; J-EVT and J-PCI investigators | J Atheroscler Thromb. 2019 Nov 21 | Compared with acute coronary syndrome patients, critical limb ischemia demonstrated a larger peak-to-trough ratio of seasonality (1.75 versus 1.21; P<0.001), and a later peak appearance. These distinct features were observed in a diabetic population and a non-diabetic population |
13 | Incidence and In-Hospital Outcomes of Patients Presenting With Stent Thrombosis [19] | Ohno Y, Yamaji K, Kohsaka S, Inohara T, Amano T, Ishii H, Kadota K, Nakamura M, Nakazawa G, Yoshimachi F, Ikari Y | Am J Cardiol. 2019 Dec 9. pii: S0002-9149(19)31361-X | Despite younger age, patients with ST had significantly higher incidence of in-hospital mortality and cardiovascular complications, including recurrent ST, compared with those without |
