Insuficiencia cardiaca en España: epidemiologĂa e importancia del grado de adecuaciĂłn a las guĂas de práctica clĂnica
[Resumen] En el presente artĂculo se abordan aspectos de la magnitud de la insuficiencia cardiaca, con especial menciĂłn a la carga que supone la enfermedad en nuestro medio. Se discuten, asimismo, los problemas para estimar esta magnitud debidos al propio carácter de sĂndrome de esta condiciĂłn y a constituir un sendero comĂşn final a mĂşltiples enfermedades. En un segundo apartado se presentan algunas reflexiones acerca del valor de las guĂas de práctica clĂnica y de los problemas para que las intervenciones que han demostrado su eficacia en el entorno controlado de un ensayo clĂnico se generalicen en la práctica clĂnica cotidiana, a fin de aprovechar al máximo su potencial beneficio. Finalmente, se sugieren algunos puntos para mejorar tanto la adhesiĂłn de los profesionales a las guĂas de práctica clĂnica como la de los pacientes al tratamiento que se les indique
Diagnostic protocol for genetic cardiomyopathies
Protocolos de práctica asistencial[Resumen] CaracterĂsticas generales. Las miocardiopatĂas genĂ©ticas engloban un grupo heterogĂ©neo de enfermedades. Algunas afectan de forma aislada al mĂşsculo cardĂaco, en otros casos forman parte del espectro de una enfermedad sistĂ©mica. Con frecuencia comienzan en la juventud, constituyendo una causa importante de morbimortalidad en los pacientes afectados.
DiagnĂłstico. Existen manifestaciones clĂnicas, alteraciones electrocardiográficas y pruebas de imagen que permiten el diagnĂłstico de la afectaciĂłn estructural cardĂaca. Los avances en el campo de la genĂ©tica han permitido el conocimiento de un amplio porcentaje de mutaciones causales de estas enfermedades. Una vez realizado el diagnĂłstico del paciente afectado, es necesario ampliar el estudio a la familia, para asĂ identificar a individuos asintomáticos y realizar una estratificaciĂłn pronĂłstica[Abstract] General characteristics. Genetic cardiomyopathies encompass a heterogeneous group of diseases. Some affect the heart muscle in isolation, while in other cases they form part of the spectrum of a systemic disease. These diseases frequently start in youth and represent a significant cause of morbidity and mortality in those affected by the disease.
Diagnosis. There are clinical manifestations, electrocardiographic abnormalities and imaging tests that enable the diagnosis of cardiac structural involvement. Advances in the field of genetics have revealed a high rate of causal mutations of these diseases. Once the affected patient has been diagnosed, the study needs to be extended to the family to thereby identify asymptomatic individuals and to perform a prognostic stratification

Gene expression profiling for monitoring graft rejection in heart transplant recipients
Outcomes[Abstract] Heart transplantation is a life-prolonging therapy for many patients with stage D heart failure and other forms of advanced heart disease. However, graft rejection and/or immunosuppression-related side effects are major causes of morbidity and death among heart transplant patients. Graft rejection monitoring remains a challenge. It would be desirable to be able to detect rejection early enough and specifically enough to prevent allograft dysfunction without unnecessary overimmunosuppression. Hitherto, the main technique employed in monitoring the rejection status of a transplanted heart has been endomyocardial biopsy (EMB), which allows rejection to be screened for and monitored on the basis of the extent and distribution of lymphocytic infiltrates and associated myocardial damage. However, EMB has significant limitations: it is invasive, its sensitivity is limited by sampling efficacy, and it suffers from considerable between-observer variability. Although many noninvasive techniques have been investigated, none so far has proved able to match the performance of EMB. Currently, a multiparametric approach is employed that comprises clinical examination for signs or symptoms of heart failure, EMBs, drug level monitoring, allograft function tests (mainly echocardiographic studies), and screening for allograft vasculopathy. Gene expression profiling may be a promising tool for this purpose
