Abnormal Heart Rate Characteristics Are Associated with Neonatal Mortality

Is abnormal adrenergic activation associated with abnormal Heart Rate Recovery?

BACKGROUND Heart Rate Recovery (HRR) reflects the capacity of the cardiovascular system to reverse the vagal withdrawal caused by exercise. Scintigraphy with metaiodobenzylguanidine (I(123) MIBG) evaluates innervation and cardiac adrenergic activation. The association of these two methods is not well established. OBJECTIVE To evaluate the association between HRR and washout rate (WO) of I(123...

Socioeconomic Factors Associated With Mortality Rate Caused by Severe Stroke

Background: Stroke is one of the most important causes of disability-adjusted life years lost. Low socioeconomic status is associated with increased stroke-related morbidity and mortality. Objective: This study aimed to investigate in-hospital mortality rate caused by severe cases of ischemic and hemorrhagic stroke and its relationship with patients’ socioeconomic status. Materials and Method...

Are Abnormal Yolk Sac Characteristics Important Factors in Abortion Rates?

variability connections are associated with reduced heart rate

Aim—To determine whether cavopulmonary connections are associated with abnormalities of heart rate variability. Methods—Heart rate variability was studied by 24 hour Holter monitoring in 39 patients (mean (SD) age 12.2 (4.1) years) who underwent cavopulmonary connection operations (partial in 12, total in 13, and atriopulmonary in 14). Two control groups were used: 18 healthy children (11.1 (2....

Heart Rate at Hospital Discharge in Patients With Heart Failure Is Associated With Mortality and Rehospitalization

BACKGROUND Whether heart rate upon discharge following hospitalization for heart failure is associated with long-term adverse outcomes and whether this association differs between patients with sinus rhythm (SR) and atrial fibrillation (AF) have not been well studied. METHODS AND RESULTS We conducted a retrospective cohort study from clinical registry data linked to Medicare claims for 46 217...
