Comparative StudyAssociation between the admission time and the clinical findings in patients with acute heart failure.
There have been few reports about the clinical significance of the time of admission for acute heart failure (AHF). ⋯ 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.

Although its prevalence is relatively low in pregnant women, heart disease is the most important cause of maternal mortality. Problems may arise due to hemodynamic burden and the hypercoagulable state of pregnancy. Heart disease may be congenital or acquired. ⋯ Treatment options should be discussed with the future parents, as they may affect both mother and child. In general, the preferred route of delivery is vaginal. The optimal care for pregnant women with heart disease requires multidisciplinary involvement and is best concentrated in tertiary centers.

ReviewTako-tsubo cardiomyopathy: clinical presentation and underlying mechanism.
Since Dr Sato at Hiroshima City Hospital first recognized and reported the concept of tako-tsubo cardiomyopathy in 1990, this disorder has become accepted worldwide as a distinct clinical entity. Tako-tsubo cardiomyopathy is an important disorder as a differential diagnosis of acute myocardial infarction. This disorder usually occurs in postmenopausal women of an advanced age, and is characterized by transient left ventricular apical wall motion abnormalities associated with emotional or physical stress. ⋯ The prognosis is generally favorable. However, several acute complications have been reported such as congestive heart failure, cardiac rupture, hypotension, left ventricular apical thrombosis, or Torsade de Pointes. Several possible mechanisms such as multivessel coronary artery spasm, coronary microvascular dysfunction, myocarditis, or catecholamine toxicity have been proposed to explain tako-tsubo cardiomyopathy, but its pathophysiology is not well understood.

Effect of intravenous adrenaline before arrival at the hospital in out-of-hospital cardiac arrest.
There is some evidence in prospective randomized clinical trials that the administration of adrenaline (AD) before admission for the treatment of out-of-hospital cardiac arrest did not improve survival to hospital discharge. The aim of this study was to evaluate our real-world experience regarding the efficacy of intravenous AD in out-of-hospital cardiac arrest at our university hospital. In this retrospective study, we enrolled and divided 644 patients into AD (AD administration before arrival at the hospital) and non-AD (no AD administration before arrival at the hospital) groups. ⋯ We analyzed whether intravenous AD before arrival in patients with intrinsic cause was effective. The outcomes in the AD group were similar to those in the non-AD group. In conclusion, our study indicated that AD administration before arrival at the hospital for the treatment of out-of-hospital cardiac arrest did not improve the clinical outcome.

Impact of obstructive sleep apnea on left atrial functional and structural remodeling beyond obesity.
To evaluate the left atrial (LA) volume and function of obese patients with/without obstructive sleep apnea (OSA) and its association with left ventricular (LV) diastolic function independent of obesity. ⋯ LA structural and functional remodeling was significantly correlated with the severity of OSA and LV diastolic filling pressure. OSA impaired LA wall compliance and passive contraction independent of obesity.
