E.5.2 | Secondary end point(s) |
1. Grade Changes NYHA functional comparatively between groups.
2. Possible cardiac events during follow-up (death, myocardial infarction, repeat revascularization).
3. Need for hospitalization or major arrhythmias. It will assess the presence or absence of symptoms or arrhythmias during the 6 month follow-up. To do this, patients will be followed from the clinical point of view so close, with frequent phone calls and periodic revisions of an outpatient hospital.
4. Changes in global function and left ventricular segmental by studying myocardial deformation dimensional speckle tracking echocardiography (EST2D) and three-dimensional echocardiography in a comparison between the conditions for monitoring in each patient and between groups. |
1. Cambios de Grado funcional de la NYHA de forma comparativa entre los grupos.
2. Posibles eventos cardiacos durante el seguimiento (mortalidad, infarto, necesidad de nueva revascularización).
3. Necesidad de ingreso hospitalario o presencia de arritmias mayores. Se valorará la presencia o ausencia de síntomas o arritmias durante los 6 meses de seguimiento. Para ello, los pacientes serán seguidos desde el punto de vista clínico de forma estrecha, con llamadas telefónicas frecuentes y revisiones hospitalarias periódicas de forma ambulatoria.
4. Cambios en la función global y segmentaria del ventrículo izquierdo mediante el estudio de la deformación miocárdica con ecocardiografía Speckle tracking bidimensional (EST2D) y ecocardiografía tridimensional de forma comparativa entre las condiciones de seguimiento en cada paciente y entre grupos. |
