Interest of blood pressure exercise graph in the diabetic population

The evaluation of the real blood pressure in the diabetic population has a major interest. Arterial blood pressure measure during standardised exercis e test could be a supplementary aid in this field of research. This retrosp ective work is based on 134 diabetic patients compared with age, sex and bo dy mass index matched controls. All of them were tested with a standardised protocol of bicycle ergometer. In the diabetic group, 62 patients present a microalbuminuria over 30 mg/da y. The heart rate and arterial pressure do not differ between diabetics and controls before, during, and after the exercise. The registered parameters at the top of the effort are exactly the same for the pulse the systolic a nd the diastolic blood pressure. Systolic blood pressure gradient during ef fort is not different between the two groups. The presence of microalbuminu ria into the diabetic group do not provoke any modification of cardiac freq uency or pressure during the effort. Nevertheless a decrease in systolic bl ood pressure gradient is noted into the microalbuminuria group despite thei r older age is in favour of an increase in this parameter. Exercise test ha s a main place to track down coronary disease and the field of interest is the same that non diabetic patients to find white coat hypertension,to valu e arterial pressure reactivity during effort of hypertensive athletes or bo rder line hypertensives. The signification and interest of the modification of systolic blood pressure gradient should to be evaluated by other works.
