Short-Term Effects of Ambient Temperature on Acute Heart Failure Decompensation: Phenotype-Specific Risk in a Time-Stratified Case-Crossover Study

Takahiro Jimba, Shun Kohsaka, Yasuyuki Shiraishi, Makoto Takei et autres

BACKGROUND: Acute decompensated heart failure (ADHF) exhibits seasonal variations, yet the short-term effects of ambient temperature, independent of seasonality, remain poorly studied. Moreover, temperature-sensitive exacerbation phenotypes are not well defined, limiting the development of effective preventive strategies. We aimed to investigate the …

Serial Optical Coherence Tomography Observations following Newer-Generation Drug-Eluting Stents That Combine Ultrathin Struts and Nanocoating in Patients with ST-Elevation Myocardial Infarction after Plaque Rupture

Yosuke Oishi, Hiroyoshi Mori, Naoki Matsukawa, Kunihiro Ogura et autres

Newer-generation drug-eluting stents (DES) that combine ultrathin struts and nanocoating (biodegradable polymer sirolimus-eluting stents, BP-SES) could improve vascular healing in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI) over previous DES. However, its time course has not been …

Comprehensive Self-Management of Heart Failure

Shunsuke Kiuchi, Shigeto Tsukamoto, Rie Sato, Keisuke Hosono et autres

In response to the heart failure (HF) pandemic, it is important to introduce appropriate pharmacological and non-pharmacological treatments for HF patients. In addition, self-management of HF, including the continuation of appropriate pharmacological treatment, is also important. There have been many reports on …

Hospital Variability in the Use of Vasoactive Agents in Patients Hospitalized for Acute Decompensated Heart Failure for Clinical Phenotypes

Yasuyuki Shiraishi, Nozomi Niimi, Shun Kohsaka, Kazumasa Harada et autres

BACKGROUND: The absence of practice standards in vasoactive agent usage for acute decompensated heart failure has resulted in significant treatment variability across hospitals, potentially affecting patient outcomes. This study aimed to assess temporal trends and institutional differences in vasodilator and inotrope/vasopressor utilization …

Assessment of Residual Vasospasm in Patients with Plaque Rupture or Plaque Erosion using Optical Coherence Tomography

Teruo Sekimoto, Hiroyoshi Mori, Shinji Koba, Taito Arai et autres

AIMS: Coronary vasospasm is associated with acute coronary syndrome (ACS) and may persist during primary percutaneous coronary intervention (PCI). We aimed to elucidate the incidence, morphological characteristics, and prognostic impact of residual vasospasm in plaque rupture (PR) and plaque erosion (PE) lesions …

Association between Eicosapentaenoic Acid to Arachidonic Acid Ratio and Characteristics of Plaque Rupture

Teruo Sekimoto, Shinji Koba, Hiroyoshi Mori, Taito Arai et autres

AIMS: Eicosapentaenoic acid (EPA) has shown beneficial effects on coronary plaque stabilization. Based on our previous study, we speculated that EPA might be associated with the development of healed plaques and might limit thrombus size. This study aimed to elucidate the association …

Association of Ambient Temperature and Acute Heart Failure with Preserved and Reduced Ejection Fraction

Takahiro Jimba, Shun Kohsaka, Masao Yamasaki, Toshiaki Otsuka et autres

Abstract Aims Evidence on the association between ambient temperature and the onset of acute heart failure (AHF) is scarce and mixed. We sought to investigate the incidence of AHF admissions based on ambient temperature change, with particular interest in detecting the difference …
