RESUMO
Objective: The present work aimed to study the sensitivity of exercise stress ECG in determining the prevalence of stress induced myocardial ischemia in young hypertensive Egyptian patients
Methods: 100 hypertensive patients with age range between 16-35 years and 20, healthy adult with the same age wee subjected to thorough clinical- examination, resting ECG, chest-x -ray complete echocardiographic study including LV mass index calculation and Doppler study. They also were subjected to laboratory tests to assess their lipid profile. Exercise stress testing according to bounce protocol was done for all subjects
Results: The results showed that five patients out of 40 patients with LVH had ST-segment depression >2mm while no one in patients without LVH, and control group had there changes. There was a significant dyslipidemia in hypertensive patients as compared to control group. There was a significant diastolic dysfunction in hypertensive patient as compared with control group and it was more significantly compared in those with LVH than those without LVH. The HR, blood pressure response to exercise was significantly impaired in hypertensive patients in comparison to control subjects and this response was more significantly impaired in those with LVH as compared with those without LVH
Conclusion: 1. Exercise stress test may be of great value in assessment of young hypertensive patients. 2. Hypertension is usually associated with dyslipidemia. 3. Left ventricular hypertrophy is an important factor in inducing stress ST- segment depression. 4. The hemodynamic response of hypertensive patients was significantly impaired
