1. Difficulties in maintaining potassium homeostasis in patients with heart failure.
Match Strength: 6.545
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 »

2. Radiation dose and long term risk of cardiac pathology following radiotherapy and anthracyclin for a childhood cancer.
Match Strength: 5.405
PURPOSE: To determine the cardiac status in children 15 years (yrs) or more after a solid tumour treatment. PATIENTS AND METHODS: Of the 447 patients, 229 were fully studied and 218 were not. The following cardiac evaluation was proposed to all the 447 consecutive patients: (1) cardiac Doppler US by one of two expert cardiologists; (2) cardiac rhythm and conduction abnormalities including 24-h holter ECG; (3) (131)I-mIBG myocardial scintigraphy; (4) serum brain natriuretic peptide levels at rest; (5) an exercise test with VO(2)max measurement. The radiation dose delivered to 7 points in the ... Read More »

3. A Large-Scale Analysis of Ion Channel Gene Expression in the Mouse Heart during Perinatal Development.
Match Strength: 5.304
The immature and mature heart differs from each other in terms of its excitability, action potential properties, contractility and relaxation. This includes upregulation of repolarizing K(+) currents, an enhanced inward rectifier K(+) current and changes in Ca(2+), Na(+) and Cl(-) currents. At the molecular level, the developmental regulation of ion channels is scantily described. Using a large-scale real-time quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) assay, we performed a comprehensive analysis of ion channel transcript expression during perinatal development in ...

4. Significance of left atrial contractile function in asymptomatic subjects with hereditary hemochromatosis.
Match Strength: 5.242
Patients with hereditary hemochromatosis (HH) have been reported to develop diastolic functional abnormalities detectable by echocardiography, but it is unknown whether these occur in asymptomatic subjects. Thus, this study tested whether echocardiographic left ventricular (LV) relaxation abnormalities are detectable in subjects with asymptomatic HH. Forty-three asymptomatic subjects with HH (C282Y homozygosity in the HFE gene) and 21 age- and gender-matched control subjects without known HFE mutations underwent echocardiography with comprehensive diastolic functional evaluations. Subjects ... Read More »

5. Association of diagnosis of ischaemic heart disease, diabetes mellitus and heart failure with cognitive function in the elderly population.
Match Strength: 5.129
OBJECTIVE: The aim of this study was to describe the association between ischaemic heart disease (IHD), diabetes mellitus (DM) and heart failure (HF) and the prevalence of cognitive impairment. METHODS: In a cross-sectional, community-based study in Karlskrona, Sweden, 1402 participants of the Swedish National Study on Ageing and Care (60-96 y) underwent a medical examination and psychological testing including the Mini Mental State Examination (MMSE). Of these, 58% stated that they were treated for hypertension, IHD, DM or HF, or had ECG abnormalities (positive screen). RESULTS: The ... Read More »

6. The management of hypoplastic left heart syndrome with a right aortic arch.
Match Strength: 4.923
The combination of hypoplastic left heart syndrome and a right-sided aortic arch is extremely rare and lethal. To the best of our knowledge, no patient with this combination has previously been reported as surviving initial palliation. The anatomic variant is associated with abnormalities in the arteries branching from the aortic arch, making it difficult to construct a reliable source of flow of blood to the lungs. We present here a patient with this combination who survived an initial Damus-Kay-Stansel procedure combined with placement of a conduit from the right ventricle to the pulmonary ... Read More »

7. Relationship between lipid abnormalities and insulin resistance in Japanese school children.
Match Strength: 4.192
OBJECTIVE: Dyslipidemia and insulin resistance (IR) are risk factors for coronary heart disease (CHD) in adults. To help prevent the development of CHD, it may be useful to understand the relationship between lipid abnormalities and IR during childhood. METHODS AND RESULTS: IR was assessed by the homeostasis model approximation index. We studied 1175 Japanese school children (642 boys and 533 girls), aged between 7 and 12 years. Obesity was defined by the body mass index standard deviation score (BMISD) (obese: BMISD > or = 2.0). BMISD was most significantly associated with IR in nonobese ... Read More »

8. Cardiac imaging in rheumatic diseases.
Match Strength: 3.971
The majority of the imaging techniques in cardiology could be applied in rheumatic diseases (RDs), such as echocardiography, single-photon emission computed tomography (SPECT), radionuclide ventriculography, angiography, cardiovascular MRI and CT. Inflammatory pericardial involvement is the most common cardiac manifestation in various forms of RD. Echocardiography is the gold standard for diagnosis of pericardial abnormalities, demonstrating location and amount of pericardial effusion. Cardiac MRI and CT can be used to assess the features of pericardial effusions and peracardial structures. In ... Read More »

9. Nailfold capillaroscopy is useful for the diagnosis and follow-up of autoimmune rheumatic diseases. A future tool for the analysis of microvascular heart involvement?
Match Strength: 3.650
Raynaud's phenomenon (RP) represents the most frequent clinical aspect of cardio/microvascular involvement and is a key feature of several autoimmune rheumatic diseases. Moreover, RP is associated in a statistically significant manner with many coronary diseases. In normal conditions or in primary RP (excluding during the cold-exposure test), the normal nailfold capillaroscopic pattern shows a regular disposition of the capillary loops along with the nailbed. On the contrary, in subjects suffering from secondary RP, one or more alterations of the capillaroscopic findings should alert the ... Read More »

10. Cardiac arrhythmias and conduction disturbances in autoimmune rheumatic diseases.
Match Strength: 2.931
Rhythm and conduction disturbances and sudden cardiac death (SCD) are important manifestations of cardiac involvement in autoimmune rheumatic diseases (ARDs). In patients with rheumatoid arthritis (RA), a major cause of SCD is atherosclerotic coronary artery disease, leading to acute coronary syndrome and ventricular arrhythmias. In systemic lupus erythematosus (SLE), sinus tachycardia, atrial fibrillation and atrial ectopic beats are the major cardiac arrhythmias. In some cases, sinus tachycardia may be the only manifestation of cardiac involvement. The most frequent cardiac rhythm ... Read More »

11. Modified Japanese medaka embryo-larval bioassay for rapid determination of developmental abnormalities.
Match Strength: 2.912
The Japanese medaka (Oryzias latipes) early-life-stage bioassay (18-day test) provides a suitable laboratory model for the evaluation of toxicant impact. The naturally high variability in the time to hatch for medaka embryos is, however, a major limitation in terms of the duration of the test. In this study, the 18-day test was modified to use agitation to synchronize hatch and reduce time to hatch for nonexposed embryos. Then, bioassays were conducted using two different complex mixtures (polycyclic aromatic hydrocarbons (PAHs) and naphthenic acids (NAs)) to compare the sensitivity of the ... Read More »
