[Transient subclavian artery spasm observed during percutaneous coronary intervention for acute myocardial infarction.]
Authors: Karakurt O, Kılıç H, Akdemir R
A 68-year-old man with a history of two coronary artery bypass operations was admitted with acute inferior myocardial infarction (AMI) and cardiogenic shock. The electrocardiogram showed ST-segment elevation in leads D2, D3, and aVF. Coronary angiography demonstrated a 75% thrombotic stenosis in the right coronary artery (RCA), 90-99% stenosis in the intermediate coronary artery, and plaques in the circumflex artery. While assessing the patency of bypass grafts, a 99% stenosis was noted in the distal subclavian artery. The culprit artery was deemed to be the RCA, and after direct stenting, TIMI III flow was achieved. Ten days later, stent implantation was performed for the intermediate coronary artery, at which time distal subcla......

The prevalence and predictors of atrial fibrillation in hemodialysis patients.
CONCLUSION: Our findings highlight age and right atrial diameter as independent predictors of atrial fibrillation in hemodialysis patients. In addition, the E/E' ratio and pulmonary artery pressure may be considered new risk factors of atrial fibrillation in this population.

Pre-hospital ECG for acute coronary syndrome in urban India: A cost-effectiveness analysis
Conclusions:
While direct presentation to the hospital with acute chest pain is preferable, in urban Indian patients presenting first to a GP, an ECG performed by the GP is a cost-effective strategy to reduce disability and mortality. This strategy should be clinically studied and considered until improved emergency transport services are available. (Source: BMC Cardiovascular Disorders)...

Comparison of three mobile devices for measuring R–R intervals and heart rate variability: Polar S810i, Suunto t6 and an ambulatory ECG system
Abstract The first aim of this study was to compare an ambulatory five-lead ECG system with the commercially available breast belt
measuring devices; Polar S810i and Suunto t6, in terms of R–R interval measures and heart rate variability (HRV) indices.
The second aim was to compare different HRV spectral analysis methods. Nineteen young males (aged between 22 and 31 years,
median 24 years) underwent simultaneous R–R interval recordings with the three instruments during supine and sitting rest,
moderate dynamic, and moderate to vigorous static exercise of the upper and lower limb. For each subject, 17 R–R interval
series of 3-min length were extracted from the whole recordings and then analyzed in frequency domain using (1) a fast Fourier
transform (FFT), (2......

Dr Chris Kingswood : Kidney monitoring workshop, 2009 TSA AGM
In his kidney monitoring workshop at the AGM in November last year, Dr Chris Kingswood (Consultant Nephrologist and Voluntary Head of Research TSA) was asked the following questions:
Q: My child is 6 and has had a kidney ultrasound at 1 year and 4 years, both of which were clear. Does he need one final scan?
A: He should have repeat scans up to his mid 30s. The kidney retains its growth potential until mid-adult life so there is a continuing risk. However if nothing is found, these can be done less frequently. Perhaps every 3 years until mid teens and then 5-yearly (But these are “best guesses”).
Q: Can AMLs start growing at any age?
A: Yes, they can, but AMLs tend to stop growing by the age of 35 as this is when the kidney itself stops growing. The important thing to know ab......

New cholesterol drug tested
Conclusion
This is an important and well-conducted trial, which has demonstrated the potential of a drug, eprotirome, to lower cholesterol levels. However, conclusions about the effects of this drug should not be made too prematurely and much further research is needed:
So far, use of the drug alone has not been compared to statin treatment. In this trial eprotirome or inactive placebo was only ever given in addition to people’s long-term statins. Therefore no comparison of cholesterol-lowering effect of each of the treatments alone can be made.
Only a small number of people were included in the trial: 47 on the 25microgram dose, 46 on 50micrograms, and 44 on the 100microgram dose of eprotirome. These groups of participants are too small to draw any conclusions on the safety or eff......

Atypical takostubo cardiomyopathy associated with nasal packing for paranasal sinus surgery
We present the case of a 24-year-old female with atypical presentation of TC occurring in the setting of paranasal sinus surgery under local anaesthesia with post-surgical nasal packing. She did not demonstrated ST-segment elevation on electrocardiogram, but transient moderate LV systolic dysfunction and localized wall motion abnormality affecting basal to mid-ventricular anterior and anteroseptal wall. She rapidly and completely recovered without sequelae. (Source: European Journal of Echocardiography)...

'2' much mitral tissue
A 73-year-old female patient was referred for evaluation after suffering an atypical chest pain. Physical examination and ECG were normal. The echocardiogram showed a normal ventricular function. Attached to the anterior leaflet an accessory mitral valve tissue was identified. In systole, this mitral tissue creates an image that looks like the ‘number 2’.

Anti-inflammatory effect of catechin on cultured human dental pulp cells affected by bacteria-derived factors
In this study, we investigated the effect of epigallocatechin-3-gallate (EGCG) and epicatechin gallate (ECG), the major components of green tea catechins, on the expression of pro-inflammatory cytokines and adhesion molecules in human dental pulp cells stimulated with bacteria-derived factors such as lipopolysaccharide (LPS) and peptidoglycan (PG). The expression of interleukin (IL)-6 and of IL-8 was examined using the reverse transcription[ndash]polymerase chain reaction and enzyme-linked immunosorbent assays. The expression of intercellular adhesion molecule-1 (ICAM-1) and of vascular cell adhesion molecule-1 (VCAM-1) on dental pulp cells was analyzed using flow cytometry. The presence of EGCG and ECG significantly reduced, in a concentration-dependent manner, the expression of IL-6 and ......

Classification of Arrhythmia Using Hybrid Networks
Abstract Reliable detection of arrhythmias based on digital processing of Electrocardiogram (ECG) signals is vital in providing suitable
and timely treatment to a cardiac patient. Due to corruption of ECG signals with multiple frequency noise and presence of
multiple arrhythmic events in a cardiac rhythm, computerized interpretation of abnormal ECG rhythms is a challenging task.
This paper focuses a Fuzzy C- Mean (FCM) clustered Probabilistic Neural Network (PNN) and Multi Layered Feed Forward Network
(MLFFN) for the discrimination of eight types of ECG beats. Parameters such as fourth order Auto Regressive (AR) coefficients
along with Spectral Entropy (SE) are extracted from each ECG beat and feature reduction has been carried out using FCM clustering.
The cluster centers......

Effects of the Selective alpha(1A)-Adrenoceptor Antagonist Silodosin on ECGs of Healthy Men in a Randomized, Double-Blind, Placebo- and Moxifloxacin-Controlled Study.
Authors: Morganroth J, Lepor H, Hill LA, Volinn W, Hoel G
In order to determine the effects of therapeutic and supratherapeutic doses of silodosin on QT interval, healthy men (N = 186; aged 18-45 years) were randomized to receive silodosin (8 or 24 mg) or placebo for 5 days or moxifloxacin 400 mg (positive control, known to prolong QT) once on day 5. At baseline and on day 5, five ECGs were recorded 0.25 h before dosing and 1, 1.5, 2, 3, 4, 6, 8, 10, and 23.5 h after dosing. Adjusted mean differences (analysis of covariance) between silodosin and placebo in the change in individual heart rate-corrected QTc (QTcI) from baseline to day 5 were <5 ms at all times (all 90% confidence interval (CI) upper limits <10 ms). The QTcI difference for moxifloxacin compared with placebo often e......
