Comparative StudyInfluence of ambulance crew's length of experience on the outcome of out-of-hospital cardiac arrest.
To investigate whether an ambulance crew's length of experience affected the outcome of out-of-hospital cardiac arrest. ⋯ Survival from out-of-hospital cardiac arrest varies with the type of ambulance crew and length of experience after qualification. Experience in the field seems important as paramedics achieve better survival rates after just 1 year's experience, while technicians need to have more than 4 years' experience to improve survival.

Comparative StudyPrevalence of heart failure and left ventricular dysfunction in the general population; The Rotterdam Study.
To determine the prevalence of heart failure and symptomatic as well as asymptomatic left ventricular systolic dysfunction in the general population. ⋯ The prevalence of heart failure is appreciable and does not differ between men and women. The majority of persons with left ventricular systolic dysfunction can be regarded as having asymptomatic left ventricular systolic dysfunction.

Comparative StudyIncidence and clinical relevance of coronary calcification detected by electron beam computed tomography in heart transplant recipients.
Patients treated by cardiac transplantation who survive beyond one year are at significant risk from fatal coronary artery disease. The development of coronary artery calcification in these patients is discussed and methods available to detect it are reviewed. ⋯ Electron beam computed tomography is well suited to the assessment of calcium in the coronary arteries of heart transplant recipients, although the mechanisms of this calcification remain poorly understood. Calcium is detected more frequently than would be suggested by studies using intravascular ultrasound. It is associated with the presence of angiographic disease, and with some conventional risk factors for coronary disease. At follow-up the presence of coronary calcium was associated with an adverse clinical outcome, as it is in conventional ischaemic heart disease.

Prolonged QT interval predicts cardiac and all-cause mortality in the elderly. The Rotterdam Study.
To examine the association between heart-rate corrected QT prolongation and cardiac and all-cause mortality in the population-based Rotterdam Study among men and women aged 55 years or older and to compare the prognostic value of the QT interval, using different formulas to correct for heart rate. ⋯ A prolonged heart-rate corrected QT interval is an independent predictor for cardiac and all-cause mortality in older men and women. The risk associated with prolonged QT is hardly affected by the heart-rate correction formula used.
