We are very fortunate to be practicing interventional cardiology during an era of rapid clinical and technological evolution, which allows us to offer potentially life-saving options for challenging ...cardiac conditions ....
Background:Acute coronary syndrome (ACS) hospital survivors experience a wide array of late adverse cardiac events, despite considerable advances in the quality of care. We investigated 30-day and ...1-year outcomes of ACS hospital survivors using a Japanese nationwide cohort.Methods and Results:We studied 20,042 ACS patients who underwent percutaneous coronary intervention (PCI) in 2017: 10,242 (51%) with ST-elevation myocardial infarction (STEMI), 3,027 (15%) with non-ST-elevation myocardial infarction (NSTEMI), and 6,773 (34%) with unstable angina (UA). The mean (±SD) age was 69.6±12.4 years, 77% of the patients were men, and 20% had a previous history of PCI. The overall 30-day all-cause, cardiac, and non-cardiac mortality rates were 3.0%, 2.4%, and 0.6%, respectively. The overall 1-year incidence of all-cause, cardiac, and non-cardiac death was 7.1%, 4.2%, and 2.8%, respectively. Compared with UA patients, STEMI patients had a higher risk of all fatal events, non-fatal ischemic stroke, and acute heart failure, and NSTEMI patients had a higher risk of heart failure.Conclusions:The results from our ACS hospital survivor PCI database suggest the need to improve care for the acute myocardial infarction population to lessen the burden of 30-day mortality due to ACS, heart failure, and sudden cardiac death, as well as 1-year ischemic stroke and heart failure events.
Background:With the rapid spread of COVID-19, hospitals providing percutaneous coronary intervention (PCI) were placed in unique and unfamiliar circumstances. This study evaluated variations in the ...treatment of coronary artery disease according to time course of the COVID-19 pandemic in Japan.Methods and Results:The Japanese Association of Cardiovascular Intervention and Therapeutics performed serial surveys during the pandemic (in mid-April, late-April and mid-May 2020) with queries regarding the implementation of PCI. Hospitals were asked about their treatment strategies for elective PCI and emergency PCI for ST-elevation myocardial infarction (STEMI) and high-risk acute coronary syndrome (ACS) patients. Most hospitals opted to perform primary PCI in the usual manner at the beginning of the pandemic. As the pandemic progressed, hospitals in the 7 populated areas downgraded the performance of PCI for chronic coronary syndrome and high-risk ACS, but not for STEMI patients. After the state of emergency was lifted in most prefectures in mid-May, the rate of PCI gradually normalized. Screening tests, such as polymerase chain reaction and chest computed tomography, in ACS were frequently used.Conclusions:The COVID-19 pandemic greatly affected PCI treatment in Japan. However, even in the most critical situations during the pandemic, most institutions continued to perform primary PCI normally for STEMI patients.
Background Acute heart failure ( AHF ) is a heterogeneous condition, and its characteristics and management patterns differ by region. Furthermore, limited evidence is available on AHF outside of ...Western countries. A project by the National Consortium of Acute Heart Failure Registries was designed to evaluate the trends over time in patient backgrounds, in-hospital management patterns, and long-term outcomes of patients with AHF over 9 years in Japan. Methods and Results Between 2007 and 2015, registry data for patients with AHF were collected from 3 large-scale quality AHF registries ( ATTEND / WET - HF / REALITY - AHF ). Predefined end points were trends over time in age, sex, and clinical outcomes, including short- and long-term mortality and readmission for heart failure. The final data set consisted of 9075 patients with AHF . No significant differences in patient backgrounds and laboratory findings (eg, anemia or renal function) were observed, with the exception of patient age; mean age became substantially higher over 9 years (71.6-77.0 years; P for trend, <0.001). On the contrary, length of hospital stay became shorter (mean, 26-16 days). These changes were not associated with in-hospital mortality (4.7-7.5%) or 30-day heart failure readmission rate (4.8-5.4%), as well as 1-year mortality and heart failure readmission rate (20.1-23.3% and 23.6-26.2%, respectively). Conclusions Length of hospital stay in patients with AHF shortened over the 9-year period despite the increasing age of the patients. However, short- and long-term outcomes do not seem to be affected; continuous efforts to monitor clinical outcomes in patients with AHF are needed.
Adoption of the results of large-scale randomized controlled trials in percutaneous coronary intervention (PCI) may differ internationally, yet few studies have described the potential variations in ...PCI practice patterns.
Using representative national registries, we compared temporal trends in procedural volume, patient characteristics, pre-procedural testing, procedural characteristics, and quality metrics in the United States and Japan.
The National Cardiovascular Data Registry CathPCI was used to describe care in the United States, and the J-PCI was used to assess practice patterns in Japan (numbers of participating hospitals: 1,752 in the United States and 1,108 in Japan). Both registries were summarized between 2013 and 2017.
PCI volume increased by 15.8% in the United States from 550,872 in 2013 to 637,650 in 2017, primarily because of an increase in nonelective PCIs (p for trend <0.001). In Japan, the volume of PCIs increased by 36%, from 181,750 in 2013 to 247,274 in 2017, primarily because of an increase in elective PCIs (p for trend <0.001). The proportion of PCI cases for elective conditions was >2-fold greater in Japan (72.7%) than in the United States (33.8%; p < 0.001). Overall, the ratio of nonelective PCI (vs. elective PCI; 27.3% vs. 66.2%; p < 0.001) and the performance of noninvasive stress testing in patients with stable disease (15.2% vs. 55.3%; p < 0.001) was lower in Japan than in the United States. Computed tomography angiography was more commonly used in Japan (22.3% vs. 2.0%; p < 0.001).
Elective PCI is more than twice as common in Japan as in the United States in contemporary practice. Computed tomography angiography is much more frequently used pre-procedurally in Japan than in the United States.

With the widespread use of electronic medical records and administrative claims databases, analytic results from so‐called real‐world data have become increasingly important in healthcare ...decision‐making. Diabetes mellitus is a heterogeneous condition that involves a broad spectrum of patients. Real‐world database studies have been recognised as a powerful tool to understand the impact of current practices on clinical courses and outcomes, such as long‐term glucose control, development of microvascular or macro‐vascular diseases, and mortality. Diabetes is also a major global health issue and poses a significant social and economic burden worldwide. Therefore, it is critical to understand the epidemiology, clinical course, treatment reality, and long‐term outcomes of diabetes to determine realistic solutions to a variety of disease‐related issues that we are facing. In the present review, we summarise the healthcare system and large‐scale databases currently available in Japan, introduce the results from recent database studies involving Japanese patients with diabetes, and discuss future opportunities and challenges for the use of databases in the management of diabetes.
