RESUMEN
Las pruebas de esfuerzo son útiles al evaluar las enfermedades cardiovasculares. Caracterizar precozmente un desequilibrio del organismo es fundamental, por lo que nos propusimos identificar durante el ejercicio la respuesta presora, alteraciones del ritmo e isquemia del miocardio en sujetos normotensos y prehipertensos. Se realizó prueba ergométrica diagnóstica en bicicleta a 222 sujetos con presión arterial menor 140/90 mmHg, electrocardiograma normal y sin tratamiento farmacológico. Predominaron las mujeres (58.6por ciento) y sujetos de la piel blanca (41.8por ciento). La presión arterial al máximo esfuerzo fue anormal en el 45.7por ciento y de ellos el 88 por ciento era prehipertenso. Esta variable mostró una elevada diferencia significativa (p=0.0000064) entre normotensos y prehipertensos. Se detectó isquemia del miocardio y arritmia en 21 sujetos. Se concluye que la prueba de esfuerzo en estos sujetos evidencia de forma precoz alteraciones en el control de la presión arterial y que la isquemia del miocardio y las arrtimias no son frecuentes en este subgrupo.
ABSTRACT
The exertion tests are useful to evaluate cardiovascular diseases. The early characterization of an unbalance of the organism is essential. That's why, we proposed to identify during the physical exercise the pressure response, rhythm alterations and myocardial ischemia in normotensive and prehypertensive individuals. A diagnostic bicycle ergometric test was performed among 222 subjects with arterial pressure under 140/90 mmHg, normal ECG and with no drug treatment. Females (58.6 percent) and white individuals (41.8percent) prevailed. Arterial pressure on maximum effort was abnormal in 45.7 percent and 88 % of them were prehypertensives. This variable showed an elevated significant difference (p=0.0000064) between normotensive and prehypertensives. Myocardial ischemia and arrhythmia were found in 21 individuals. It was concluded that the exercise test in these subjects evidenced early alterations in the control of arterial pressure and that myocardial ischemias and arrhythmias are not common in this subgroup.
