Association between the visiting time and the clinical findings on admission in patients with acute heart failure

Abstract

The nighttime HF was characterized by high SBP, high HR, and orthopnea, and the length of ICU stay was shorter in the nighttime HF group.

Respiratory Collapse of the Inferior Vena Cava Reflects Volume Shift and Subsequent Fluid Refill in Acute Heart Failure Syndrome

“…In Japan, diuretics tend to be used in almost all patients with acute HF; Konishi et al reported that furosemide or carperitide were used in 97.9% of patients, 28 and Matsushita et al reported that furosemide was used in 94% of patients. 29 In this study, it became possible to estimate the changes in intravascular volume by the changes in hemoglobin and hematocrit because urine volume after treatment was almost the same. Nevertheless, we believed that it was important to find differences in the changes in hemoglobin and hematocrit between the groups.…”

Day vs night: Does time of presentation matter in acute heart failure? A secondary analysis from the RELAX-AHF trial

“…2,3 Patients were classified based on presentation time, not randomization for day vs. night analyses. Presentation was defined as the first recorded time of entry into the hospital system, most commonly via the ED.…”

“…Observed differences in characteristics and outcomes between AHF patients presenting during daytime vs. nighttime hours suggest potential different pathophysiological mechanisms or differences in disease severity. [1][2][3] Other acute cardiovascular processes, leading to myocardial infarction, myocardial ischemia, and sudden cardiac death occur more frequently in the early morning hours: 4 Circadian rhythms may contribute to their respective disease mechanisms. 5 Attempts to better understand potential circadian interactions from acute heart failure (AHF) clinical trials have been limited by operational constraints: Patients are primarily enrolled during 'working' hours -Monday through Friday, 0800 to 1700.…”

Prognostic effect of estimated glomerular filtration rate in patients with cardiogenic shock or cardiac arrest undergoing percutaneous veno-arterial extracorporeal membrane oxygenation

“…All physicians were trained to set up the ECLS systems within 10 min. Patients with heart disease who need intensive care are reported to be admitted more frequently during the nighttime than daytime [16]. In our hospital, it is possible to start 3 ECLS systems at the same time 24 h a day, and we can manage 5 ECLS systems simultaneously.…”
