A Very Severe Obstructive Sleep Apnea Syndrome: In a Cause of Resistant Hypertension with One Sample Case

摘要

When blood pressure values remain above the target in a hypertensive patient treated concomitantly with three anti-hypertensive drugs including a diuretic, maximum well-tolerated doses, this is a resistant arterial hypertension. In this case, it is advisable to look for a secondary cause such as a drug intake that influencing the blood pressure or the presence of obstructive sleeping syndrome (OSAS). We report a clinical case of a patient with a high cardiovascular risk at the age of 50, hypertensive and diabetic, with dyslipidemia and obesity. He was on anti-hypertensive triple therapy at an optimal dose. Her diabetes was balanced with 6.4% glycated hemoglobin. Dyslipidemia has being treated. Despite healthy diet including a low sodium diet and weight loss, blood pres- sure target was not reached. With self-measurement, the mean arterial pressure was 180/110 mmHg and on ABPM it was 167/113 mmHg. The ventilatory polygraphy finds a severe OSA with an IAH = 56.6. Treatment with PCP (Con- tinuous positive pressure) allowed this patient to control blood pressure. The search for OSA should be systematic in face of resistant hypertension, in par-  style="font-family:Verdana;">ticular in overweight or obese patients.
