2. Heart rate response during exercise predicts survival in adults with congenital heart disease.
Match Strength: 5.304
OBJECTIVES: To assess the prognostic value of heart rate response to exercise in adult congenital heart disease (ACHD) patients. BACKGROUND: An abnormal heart rate response to exercise is related to autonomic dysfunction and may have prognostic implications in ACHD. METHODS: We identified 727 consecutive ACHD patients (mean age [+/- SD] 33 +/- 13 years) with varying diagnoses and without pacemakers. Peak oxygen consumption (peak VO2), resting heart rate, and the increase in heart rate from resting level to peak exercise ("heart rate reserve") were measured. We also quantified the decrease in ...

5. Gene regulatory networks in the evolution and development of the heart.
Match Strength: 4.400
The heart, an ancient organ and the first to form and function during embryogenesis, evolved by the addition of new structures and functions to a primitive pump. Heart development is controlled by an evolutionarily conserved network of transcription factors that connect signaling pathways with genes for muscle growth, patterning, and contractility. During evolution, this ancestral gene network was expanded through gene duplication and co-option of additional networks. Mutations in components of the cardiac gene network cause congenital heart disease, the most common human birth defect. The ... Read More »

6. Difficulties in maintaining potassium homeostasis in patients with heart failure.
Match Strength: 4.164
Potassium (K) concentration plays a significant role in cell metabolism and membrane excitability. The imbalance of serum potassium is important because it can lead to life-threatening events. Potassium balance may be lost both through the neurohormonal mechanisms involved in cardiovascular diseases and through the drugs used in the treatment of this illness. Avoiding both hypo- and hyperkalemia is beneficial in several cardiovascular diseases, especially heart failure. Electrolyte abnormalities are frequently seen complications in subjects with heart failure. Malignant ventricular arrhythmias ... Read More »

8. Temperature acclimation modifies sinoatrial pacemaker mechanism of the rainbow trout heart.
Match Strength: 4.033
The hypothesis of pacemaker level origin of thermal compensation in heart rate was tested by recording action potentials (AP) in intact sinoatrial tissue and enzymatically isolated pacemaker cells of rainbow trout acclimated at 4 degrees C (cold) and 18 degrees C (warm). With electrophysiological recordings, the primary pacemaker was located at the base of the sinoatrial valve, where a morphologically distinct ring of tissue comprising myocytes and neural elements was found by histological examination. Intrinsic beating rate of this pacemaker was higher in cold-acclimated (46 +/- 6 APs/min) ... Read More »

10. Phosphodiesterase 4D and heart failure: a cautionary tale.
Match Strength: 3.978
Stimulation of several G-protein-coupled receptors (GPCRs) promotes intracellular production of cyclic adenosine 3',5'-monophosphate (cAMP) and subsequently activates protein kinase A (PKA). In the heart, beta-adrenergic receptor (beta-AR) stimulation increases contractile performance and heart rate as part of the 'fight-or-flight' stress response. Molecular organisation of PKA-effector association occurs by A kinase anchoring proteins (AKAPs), which target kinase action to specific intracellular sites. Some AKAPs interact directly with specific cAMP-hydrolysing phosphodiesterase (PDE) ... Read More »

12. A pilot investigation of the effect of extremely low frequency pulsed electromagnetic fields on humans' heart rate variability.
Match Strength: 3.765
The question whether pulsed electromagnetic field (PEMF) can affect the heart rhythm is still controversial. This study investigates the effects on the cardiocirculatory system of ELF-PEMFs. It is a follow-up to an investigation made of the possible therapeutic effect ELF-PEMFs, using a commercially available magneto therapeutic unit, had on soft tissue injury repair in humans. Modulation of heart rate (HR) or heart rate variability (HRV) can be detected from changes in periodicity of the R-R interval and/or from changes in the numbers of heart-beat/min (bpm), however, R-R interval analysis ...

16. Recent increase of neighborhood socioeconomic effects on ischemic heart disease mortality: a multilevel survival analysis of two large Swedish cohorts.
Match Strength: 3.668
Studies have shown that the decrease in ischemic heart disease mortality over the past decades was paralleled by an increase in socioeconomic disparities. Using two large Swedish cohorts defined in 1986 and 1996, the authors examined whether the effect of neighborhood socioeconomic position on ischemic heart disease mortality strengthened over the period and whether the relative contribution of individual and neighborhood socioeconomic effects changed over time. Multilevel survival models adjusted for individual factors indicated that neighborhood socioeconomic effects on ischemic heart ... Read More »
