Atrial fibrillation in patients with severe aortic stenosis.

Background: There has been no previous report evaluating the long impact of atrial fibrillation (AF) on the clinical outcomes stratified by the initial management [conservative or aortic valve replacement (AVR)] strategies of severe aortic stenosis (AS).

Methods: We analyzed 3815 patients with severe AS enrolled in the CURRENT AS registry. Patients with AF were defined as those having a history of AF when severe AS was found on the index echocardiography.

Clinical outcome after surgical aortic valve replacement in low-risk Japanese patients with severe aortic stenosis.

Two randomized control trials demonstrated that transcatheter aortic valve implantation was associated with 1-2 year clinical outcomes comparable or even superior to surgical aortic valve replacement (SAVR) in low surgical risk patients with severe aortic stenosis (AS). However, no previous study has reported the clinical outcomes after SAVR in Japanese patients with low surgical risk. From 3815 consecutive patients enrolled in the CURRENT AS registry, we retrieved 220 patients who underwent SAVR in reference to the inclusion and exclusion criteria of the PARTNER 3 trial.

Transcatheter Aortic Valve Implantation vs. Surgical Aortic Valve Replacement for Severe Aortic Stenosis in Real-World Clinical Practice.

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.

Methods: Among 3,815 patients with severe AS enrolled in the multicenter CURRENT AS (Contemporary Outcomes After Surgery and Medical Treatment in Patients With Severe Aortic Stenosis) registry in Japan, 839 conservatively managed patients who underwent echocardiography at 1-year follow-up were analyzed.

Transcatheter aortic valve implantation versus conservative management for severe aortic stenosis in real clinical practice.

Background: Transcatheter aortic valve implantation (TAVI) is criticized by some as an expensive treatment in super-elder patients with limited life expectancy. However, there is a knowledge gap regarding the magnitude of clinical benefit provided by TAVI in comparison with conservative management in patients with severe aortic stenosis (AS) in real clinical practice, which would be important in the decision making for TAVI.

Methods: We combined two independent registries, namely CURRENT AS and K-TAVI registries.

This study aimed to develop and validate a clinical scoring system to predict AS-related events within 1 year after diagnosis in asymptomatic severe AS patients.

Methods And Results: We analysed 1274 asymptomatic severe AS patients derived from a retrospective multicentre registry enrolling consecutive patients with severe AS in Japan (CURRENT AS registry), who were managed conservatively and completed 1-year follow-up without AVR.

Reasons for Choosing Conservative Management in Symptomatic Patients With Severe Aortic Stenosis - Observations From the CURRENT AS Registry.

Background: There has not been a previous report on the long-term outcomes of those patients who refuse aortic valve replacement (AVR) despite physicians' recommendations.

Methods and results: Among 3,815 consecutive patients with severe aortic stenosis (AS) enrolled in the CURRENT AS registry, the study population comprised 2,005 symptomatic patients, who were subdivided into 3 groups by their treatment strategy and the reasons for conservative strategy (Initial AVR group: n=905; Patient rejection group: n=256; Physician judgment group, n=844). The primary outcome measure was a composite of aortic valve-related death and heart failure hospitalization.

Methods: We used data from a Japanese multicentre registry, the Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis Registry, which enrolled 3815 consecutive patients with severe AS. Of those, 387 asymptomatic patients who were not referred for AVR without left ventricular dysfunction and very severe AS were subdivided into four groups based on their BNP levels (BNP<100 pg/mL, n=201; 100≤BNP<200 pg/mL, n=94; 200≤BNP<300 pg/mL, n=42 and BNP>300 pg/mL, n=50).

Asymptomatic versus Symptomatic Patients with Severe Aortic Stenosis.

It is unknown how much different are the clinical outcomes between asymptomatic and symptomatic patients with severe aortic stenosis (AS). In the CURRENT AS registry enrolling 3,815 consecutive patients with severe AS, we compared the long-term outcomes between 1808 asymptomatic and 1215 symptomatic patients (exertional dyspnea: N = 813, syncope: N = 136, and angina: N = 266) without heart failure (HF) hospitalization. Symptomatic patients had greater AS severity, and more depressed left ventricular function than asymptomatic patients without much difference in other baseline characteristics.

Malignant disease as a comorbidity in patients with severe aortic stenosis: clinical presentation, outcomes, and management.

Aim: To investigate the effect of malignancy on the outcomes of patients with severe aortic stenosis (AS) and the management strategy for AS with malignancy.

Methods And Results: Using data of 3815 patients with severe AS in a retrospective multicentre registry [CURRENT AS (Contemporary outcomes after sURgery and medical tREatmeNT in patients with severe Aortic Stenosis) registry], we compared 3-year clinical outcomes among three groups based on malignancy status: with malignancy currently under treatment including best supportive care (malignancy group), with a history of malignancy without any current treatment (past history group), or without history of malignancy (no malignancy group). Patients in the malignancy group (n = 124) were more often men and had higher prevalence of low body mass index, recurrence of malignancy, anaemia, and asymptomatic status, despite comparable surgical risks and echocardiographic parameters.

Clinical efficacy of thrombus aspiration on 5-year clinical outcomes in patients with ST-segment elevation acute myocardial infarction undergoing percutaneous coronary intervention.

Background: Adjunctive thrombus aspiration (TA) during primary percutaneous coronary intervention (PCI) was reported to promote better coronary and myocardial reperfusion. However, long-term mortality benefit of TA remains controversial. The objective of this study is to investigate the clinical impact of TA on long-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI.

Relation of contrast-induced nephropathy to long-term mortality after percutaneous coronary intervention.

There is little information on the effect of contrast-induced nephropathy (CIN) on long-term mortality after percutaneous coronary intervention in patients with or without chronic kidney disease (CKD). Of 4,371 patients who had paired serum creatinine (SCr) measurements before and after percutaneous coronary intervention and were discharged alive in the Coronary REvascularization Demonstrating Outcome Study in Kyoto registry, the incidence of CIN (an increase in SCr of ≥0.5 mg/dl from the baseline) was 5% in our study cohort.

Achievement rates of Japan Atherosclerosis Society Guidelines 2007 LDL-cholesterol goals with rosuvastatin or atorvastatin in patients who had not achieved their goal with atorvastatin.

Background: The Japan Atherosclerosis Society's 2007 Guidelines for Prevention of Atherosclerotic Cardiovascular Diseases (JAS2007GL) advocate reducing LDL cholesterol (LDL-C) to target levels in patients with dyslipidemia, but achievement rates are frequently unsatisfactory even in the presence of lipid-lowering therapy. This multicenter, open-label, randomized, parallel-group study compared the efficacy of rosuvastatin and atorvastatin on JAS2007GL LDL-C goals in Japanese patients not achieving their target goal with atorvastatin treatment.

Methods: The study involved 20 clinical institutes in Japan (Kishiwada Atherosclerosis Prevention Study [KAPS] Group).
