Prognostic impact of demographic factors and clinical features on the mode of death in high-risk patients after myocardial infarction--a combined analysis from multicenter trialsYee Guan Yap
Department of Cardiological Sciences, St George s Hospital Medical School, London, UK
Clin Cardiol 28:471-8. 2005
..Contemporary information is lacking on the effect of demographic features and clinical features on the specific mode of mortality after myocardial infarction (MI) in the thrombolytic era...
Prognostic value of blood pressure measured during hospitalization after acute myocardial infarction: an insight from survival trialsYee Guan Yap
Department of Cardiological Sciences, St George s Hospital Medical School, London, UK
J Hypertens 25:307-13. 2007
..The prognostic value of blood pressure measured during hospitalization after acute myocardial infarction (MI) has not been investigated, particularly with regard to arrhythmic death...
Potential demographic and baselines variables for risk stratification of high-risk post-myocardial infarction patients in the era of implantable cardioverter-defibrillator--a prognostic indicatorYee Guan Yap
Department of Cardiological Sciences, St George s Hospital Medical School, London, United Kingdom
Int J Cardiol 126:101-7. 2008
..Risk stratification after myocardial infarction (MI) remains expensive and disappointing. We designed a prognostic indicator using demographic information to select patients at risk of dying after MI...
T-wave alternans and left ventricular wall thickness in predicting arrhythmic risk in patients with hypertrophic cardiomyopathyValentina Otja Puntmann
St George s, University of London, London, UK
Circ J 74:1197-204. 2010
..The aim of the present study was to investigate the relationship between LV wall thickness (LVWT) and microvolt T-wave alternans (TWA), a surrogate risk marker of ventricular tachyarrhythmias (VTAs)...
Significance of maximal and regional left ventricular wall thickness in association with arrhythmic events in patients with hypertrophic cardiomyopathyValentina O Puntmann
St George s, University of London, Cranmer Terrace, UK
Circ J 74:531-7. 2010
..Patients with mild left ventricular hypertrophy (LVH) are not free of events. Regional heterogeneity of LVH may contribute to arrhythmic vulnerability...
Arrhythmic complications of electrical cardioversion: relationship to shock energyMark M Gallagher
Department of Cardiological Sciences, St George s Hospital Medical School, Cranmer Terrace, London SW17 0RE, UK
Int J Cardiol 123:307-12. 2008
..We hypothesised that more powerful shocks would exceed the upper limit of vulnerability for inducing ventricular fibrillation. The initial use of higher energy could therefore reduce arrhythmic complications...
Electrocardiographic markers of structural heart disease and predictors of death in 2332 unselected patients undergoing outpatient Holter recordingMark M Gallagher
Department of Cardiology, Policlinico Tor Vergata, Viale Oxford 81, Rome 00133, Italy
Europace 9:1203-8. 2007
..To test the hypothesis that the QS interval of ventricular ectopic beats (VEBs) (ventricular ectopic QS interval, VEQSI) would provide a marker for the presence of structural heart disease and a predictor of mortality...
Distribution and prognostic significance of QT intervals in the lowest half centile in 12,012 apparently healthy personsMark Michael Gallagher
Department of Cardiology, University of Rome Tor Vergata, Rome, Italy
Am J Cardiol 98:933-5. 2006
..In conclusion, a QTc interval of <or=330 ms is extremely rare in healthy subjects, and the presence of a QT interval in the lowest 1/2 centile of the normal range does not imply a significant risk of sudden death...
