- Broadband waves around the lower hybrid frequency (around 10 Hz) near the magnetopause are studied, using the four Cluster satellites. These waves are common at the Earthward edge of the boundary layer, consistent with earlier observations, and can have amplitudes at least up to 5 mV/m. These waves are similar on all four Cluster satellites, i.e. they are likely to be distributed over large areas of the boundary. The strongest electric fields occur during a few seconds, i.e. over distances of a few hundred km in the frame of the moving magnetopause, a scale length comparable to the ion gyroradius. The strongest magnetic oscillations in the same frequency range are typically found in the boundary layer, and across the magnetopause. During an event studied in detail, the magnetopause velocity is consistent with a large-scale depression wave, i.e. an inward bulge of magnetosheath plasma, moving tailward along the nominal magnetopause boundary. Preliminary investigations indicate that a rather flat front side of the large-scale wave is associated with a rather static small-scale electric field, while a more turbulent backside of the large-scale wave is associated with small-scale time varying electric field wave packets.

- BACKGROUND & AIMS: The COMET trial was a prospective, double-blind, randomised trial comparing carvedilol, a comprehensive adrenergic receptor antagonist, with metoprolol, a beta-1-selective agent in patients with heart failure and left ventricular systolic dysfunction. The trial showed a reduction in mortality with carvedilol that was consistent across subgroups. The purpose of this report is to describe in greater detail the heterogeneity of this population at baseline with particular reference to the impact of symptomatic severity, age and gender on patient characteristics. METHODS: A descriptive report using data entered in the COMET study data-base. RESULTS: The characteristics of the population studied were similar to those reported in previous trials of beta-blockers. Almost all patients were receiving diuretics and ACE inhibitors with few patients taking angiotensin receptor blockers. As expected, older patients had more co-morbidity. Older patients and women reported worse symptoms and poorer well-being despite similar ventricular dimensions and systolic dysfunction. NT-proBNP was higher in patients with more severe symptoms and older patients but not in women, although differences in NT-proBNP may have been confounded by differences in renal function. CONCLUSION: Age and gender, as well as the severity of cardiac dysfunction, appear to have an important effect on the severity of heart failure symptoms and patient 'well-being'. This could have important implications for the relationship between symptoms and prognosis and therefore the way in which patients are selected for clinical trials and the goals of treatment. This will be the subject of further analyses.
