Respuesta hipertensiva exagerada al ejercicio e isquemia miocárdica en pacientes con enfermedad coronaria conocida o sospechada / Exaggerated hypertensive response to exercise and myocardial ischaemia in patients with known or suspected coronary artery disease

Objetivos. La asociación entre una respuesta hipertensiva exagerada al ejercicio (RHEE) y la probabilidad de isquemia en las pruebas de esfuerzo es controvertida. Nuestro propósito fue determinar la posible asociación entre una RHEE y el desarrollo de dolor torácico y de isquemia electrocardiográfica o ecocardiográfica con el ejercicio. Pacientes y métodos. Estudio retrospectivo y observacional de 10.047 pacientes con enfermedad coronaria conocida o sospechada referidos para una ecocardiografía de ejercicio. Un análisis de regresión logística evaluó el efecto del desarrollo de una RHEE (definida como una presión arterial sistólica máxima con el ejercicio ≥ 220mmHg) y la aparición de dolor torácico y de cambios electrocardiográficos y ecocardiográficos sugestivos de isquemia. Resultados. Un total de 402 pacientes desarrollaron una RHEE. Los porcentajes de dolor torácico anginoso, isquemia electrocardiográfica y ecocardiográfica entre los pacientes con RHEE fueron del 8,2, 16,2 y 22,6%, frente al 13,8, 14,7 y 27,5%, respectivamente, en pacientes sin RHEE (p=0,001, p=0,4, p=0,032). Tras un ajuste multivariado, la RHEE se asoció con una menor probabilidad de aparición de dolor torácico anginoso inducido por el esfuerzo (OR 0,44; IC 95% 0,30-0,65; p<0,001) y de isquemia ecocardiográfica (OR 0,63; IC 95% 0,48-0,83; p=0,001), pero no con el desarrollo de isquemia electrocardiográfica. Conclusiones. La RHEE se asocia con una menor prevalencia de dolor torácico anginoso e isquemia ecocardiográfica en pacientes con enfermedad coronaria conocida o sospechada (AU)

Objectives. The association between an exaggerated hypertensive response to exercise (EHRE) and the probability of ischaemia in stress tests is controversial. Our purpose was to determine the possible association between an EHRE and the development of chest pain and electrocardiographic or echocardiographic ischaemia with exercise. Patients and methods. A retrospective observational study was conducted of 10,047 patients with known or suspected coronary artery disease referred for exercise echocardiography. A logistic regression analysis assessed the effect of developing an EHRE (defined as a maximum systolic blood pressure with exercise ≥220mmHg) and the onset of chest pain and electrocardiographic and echocardiographic changes suggestive of ischaemia. Results. A total of 402 patients developed an EHRE. The rates of angina, electrocardiographic ischaemia and echocardiographic ischaemia among the patients with an EHRE were 8.2, 16.2 and 22.6% versus 13.8, 14.7 and 27.5%, respectively, for patients without an EHRE (p=.001, p=.4, p=.032). After a multivariate fit, EHRE was associated with a lower probability of exercise-induced angina (OR, 0.44; 95% CI 0.30-0.65; p<.001) and echocardiographic ischaemia (OR, 0.63; 95% CI 0.48-0.83; p=.001) but not with the onset of electrocardiographic ischaemia. Conclusions. EHRE is associated with a lower prevalence of angina and echocardiographic ischaemia in patients with known or suspected coronary artery disease (AU)
