Diferença de pressão arterial nos membros superiores como fator de risco para desenvolvimento de doença cerebrovascular ou arterial obstrutiva periférica: estudo caso-controle.

Abstract

Objectives: Evaluate whether patients affected by stroke and peripheral arterial disease present difference between the systolic blood pressure greater than or equal to 10 mmHg upper limbs; and comparing the differences in systolic and diastolic blood pressure in those patients. Methods: The study is characterized as a case control study in which three groups of patients will be studied: patients without diseases (control), with cerebrovascular accident (CVA) and patients with Peripheral Arterial Disease (PAD), all treated at the Hospital Trauma Campina Grande, which had the pressure measured by two raters on the two upper members twice each researcher, respecting eligibility and exclusion. The end result will be calculated as the arithmetic average of the systolic and diastolic pressures. Results: The data were subjected to chi-square test. For systolic blood pressure, no statistically significant associations between belonging to a particular group and smaller or larger differences have been found between 10 mmHg members (χ2=4,41; p=0,11) were observed. But for diastolic blood pressure, significant associations were observed between belonging to the control group and have shown differences less than or equal to 10 mmHg (X2=8,50 ; p=0,01). Conclusion: No statistical significance was found in the correlation between pressure difference in the upper and stroke and PAD members, contrary to the literature that recommends considering this pressure difference greater than 10 mmHg as a possible independent risk factor.
