Resumen
Entre el 40 al 60% de los pacientes con Enfermedad Arterial Periférica mueren por enfermedad cardiovascular. La severidad de esta enfermedad se relaciona con un aumento del riesgo de eventos cardiovasculares. La anamnesis y el examen físico así como los resultados de los exámenes complementarios, son la base del diagnóstico de esta patología. El Índice Tobillo-Brazo se utiliza para diagnosticar Arteriopatía Periférica a nivel de la atención primaria por ser una prueba sencilla, indolora, no invasiva, de bajo costo, con una sensibilidad mayor de 90%. Existe, sin embargo, poca evidencia sobre cómo se relacionan los resultados con la evolución de los afectados. Con el objetivo de determinar si éste índice tiene validez como marcador pronóstico de riesgo cardiovascular, se realizó un estudio analítico, transversal no experimental, que se realizó en el Hospital Alcívar, con 85 pacientes menores de 85 años, de cualquier sexo, con diagnóstico de Infarto Agudo de Miocardio y Angina Inestable, sometidos a cateterismo cardiaco y que consintieron informadamente su participación, . Los resultados mostraron que el índice tobillo-brazo se asocia con el grado de lesión a nivel coronario (P < 0.05). También se pudo comprobar la existencia de una asociación entre el índice y la enfermedad arterial periférica (P < 0.05). El punto de corte más adecuado del índice tobillo brazo para identificar enfermedad coronaria aguda es < 0,9. Se concluyó que el índice del índice tobillo-brazo tiene un importante valor para pronosticar riesgo cardiovascular
Cardiovascular disease is the cause of 40% to 60% of mortality among patients with Peripheral Arterial Disease and the increased risk of cardiovascular events among these individuals is associated with the severity of peripheral arterial disease. Peripheral Arterial Disease’s Diagnosis is based on the accomplishment of the clinical history and the physical examination and the subsequent confirmation of the clinical suspicion with complementary examinations both invasive and non-invasive. The Ankle-Arm Index is used to diagnose Peripheral Arteriopathy at primary care level because it is a simple, painless, non-invasive, low-cost test with a sensitivity greater than 90%. There evidence as to how these results is relate to the evolution of those affected. With objective to determine if this index is valid as a prognostic marker of cardiovascular risk an analytical, non-experimental cross-sectional study was carried out. The present study was carried in the Interventional Cardiology Service’s - Hospital Alcívar from Guayaquil-Ecuador, with 85 patients younger than 85 years old, of any gender, with a diagnosis of acute myocardial infarction and unstable angina undergoing cardiac catheterization and who informed their participation. Results: ABI is associated with degree of lesion at the coronary level (P <0.05). It was also possible to verify the existence of an association between index and peripheral arterial disease (P < 0.05). The ABI value < 0.9 is the most appropriate cutoff point for identifying acute coronary disease. The conclusion is that ankle-arm index has an important value for predicting cardiovascular risk.
