Abstract

Abstract: Background: Echocardiogram is an important diagnostic tool to evaluate cardiac disease and very usefull in diagnosis and management. It is important to know the spectrum of cardiac abnormalities detected by transthoracic echocardiography, the frequency of findings that may vary depending on the prevalence of the disease and type of studied population. Objective: To know the spectrum of findings identified in resting transthoracic echocardiography in 1,468 patients. Material and methods: A 3 years retrospective review of resting transthoracic echocardiograms in 1,468 patients. Results: The age range of the 1,468 patients was from 1 day to 94 years with mean (SD) age 51 ± 7.2 years; females 52.9% (n = 776) and males 47.1% (n = 692). One hundred thirty three patients (9.05%) had normal echocardiograms; 1,335 patients had an average of 1.8 findings/patient; 2,464 findings were classified in ten different categories: heart valves abnormalities was the most frequent alteration detected in 36.47% (n = 487); diastolic dysfunction 30.71% (n = 410); and cardiac chambers dilation 27.79% (n = 371). Conclusions: Clinical history and physical examination can not be substituted by an imaging test, but with the clinical data obtained, in conjunction with an echocardiographic study, gives us clues to the diagnosis and pathophysiology of heart disease essential for the properly evaluation and management.

Resumen: Antecedentes: La ecocardiografía es una herramienta indispensable para evaluar y manejar a las enfermedades cardiacas. Es importante conocer el espectro de anormalidades cardiacas detectadas por ecocardiografía transtorácica en reposo y la frecuencia de esos hallazgos, los cuales varían de acuerdo a cada enfermedad cardiaca. Objetivo: Reportar el espectro de hallazgos ecocardiográficos en 1,468 pacientes. Material y métodos: Los estudios ecocardiográficos transtorácicos en reposo realizados durante un período de 3 años. Resultados: Un total de 1,468 pacientes con edades comprendidas entre el primer día de vida y 94 años con edad promedio y desviación estándar de 51 ± 7.2 años; correspondiendo 52.9% (n = 776) al género femenino y 47.1% al masculino (n = 692). De los estudios, 9.05% (n = 133) fueron normales; 1,335 pacientes presentaron un promedio de1.8 hallazgos/paciente; se detectaron 2,464 hallazgos catalogándose en 10 capítulos. Los tres hallazgos más frecuentes fueron: valvulares 36.47% (n = 487); disfunción diastólica 30.71% (n = 410); y dilatación de cámaras cardiacas 27.79% (n = 371). Conclusiones: Una imagen no puede sustituir a la historia clínica y a la exploración física, siendo la ecocardiografía una prolongación de esta última, permitiendo valorar la estructura y fisiología cardiaca así como sus alteraciones, por lo que actualmente es esencial su realización en la valoración cardiaca.

The Dutch experience of open access echocardiography.

C Lodewijks-van der Bolt, L. Baur, T Lenderink … (2007)

Cardiac disease is not easy to recognise in general practice. An echocardiogram is an excellent way to provide information about left ventricular mass and diastolic (dys)function and the presence of valvular heart disease. To improve diagnostic care of cardiac patients, an open access echocardiography service was established in the referral area of our hospital, where general practitioners were able to ask for an echocardiogram without referring the patient to the cardiologist. Between December 2002 and October 2006 echocardiograms were requested for 471 patients. Thirteen percent of the patients referred for dyspnoea and 3% of patients with a cardiac murmur had a left ventricular ejection fraction <40%. In 28% of patients no cardiac abnormality could be found. If we looked at the prevalence of hypertension in the referred patients, this was very high with a prevalence of up to 60% in the older age groups. If we included hypertension in the analysis, only 16% of patients had no structural cardiac or vascular abnormality. The study shows that the advantage of open access echocardiography in the Netherlands is that the general practitioner is able to make a better diagnosis and unnecessary referrals of patients with suspected cardiac disease can be avoided.
