Using ambulatory blood pressure monitoring to assess blood pressure of firefighters with parental history of hypertension

Carlos Eduardo de Mattos et al. Marco Antonio de Mattos Daniele Gusmão Toledo Aristarco Gonçalves de Siqueira Filho

OBJECTIVE: To evaluate the influence of family history of systemic arterial hypertension (FSAH) on the effect of stress from work in Uniformed Firefighters (BMCs) through Ambulatory Blood Pressure Monitoring (ABPM). METHODS: A prospective case-control study. Sixty-six healthy BMC underwent ABPM during 12 hours of work at the Communication Center (CC). Thirty-four had hypertensive parents (group 1) and thirty-two had normotensive parents (group 2). RESULTS: Group I differed from group 2 in that it showed higher mean systolic (134.1 ± 9.9 mmHg X 120.8 ± 9.9 mmHg p < 0.0001) and diastolic (83.8 ± 8.3 mmHg X 72.9 ± 8.6 mmHg p < 0.001) blood pressure, in addition to greater systolic (31.4 ± 25.6 % X 9.4 ± 9.4 % p = 0.0001) and diastolic (28.3 ± 26.6 % X 6.1 ± 8.9 % p = 0.0001) loads. The prevalence of systemic arterial hypertension (SAH) in group 1 at the workplace was 32.3%. Monitored away from the job, these subjects showed normal blood pressure (functionally hypertensive). Group 2 revealed normal blood pressure (BP) at work. CONCLUSION: Higher blood pressure in BMC with hypertensive parents is explained independently by the SAH. Subjects who developed SAH during their work at the CC may be considered functionally hypertensive, whereas those with normotensive parents and who underwent psychological stress are free of blood pressure changes.

Predictive factors for pregnancy hypertension in primiparous adolescents: analysis of prenatal care, ABPM and microalbuminuria

Regina Coeli Marques de Carvalho et al. Henry de Holanda Campos Zenilda Vieira Bruno Rosa Maria Salani Mota

OBJECTIVE: To quantify PH prevalence in primiparous adolescents; define predictive factors for the occurrence of PH and its impact on newborns. METHODS: We followed 29 primiparous adolescents from the prenatal period through the 12th week of the puerperium, with a mean of sixteen years of age, served at the Outpatient Facility for Adolescents of Maternidade Escola Assis Chateaubriand (MEAC) of Universidade Federal do Ceará (Fortaleza, Brazil). The pregnant adolescents were divided into two groups, that is, those who remained normotensive (Group I) and those who developed PH (Group II). The variables investigated in the assessment of the value of predictability for the development of PH were anthropometric measures, socioeconomic aspects, smoking habit, inheritance for SAH (father/mother), prenatal tests requested in the first prenatal care visit in addition to microalbuminuria and ambulatory blood pressure monitoring (ABPM) in the 28th week of gestation. The pregnant adolescents were followed up at delivery and late puerperium (12th week after the puerperium). The newborns to the mothers included in our study were assessed at birth according to the Apgar score and the Capurro method, for weight, height and perinatal hypoxia. RESULTS: The prevalence of PH was 51.7%. Inheritance for SAH presented the highest predictive value for PH with an odds ratio of 10.99. Diastolic arterial pressure equal to or above 70 mmHg at the gestational age of 35 weeks was statistically significant as a predictive value for PH. At ABPM we found a predictive value for PH: diastolic pressure load during alertness, diastolic and systolic pressure load during night sleep, pressure variability and maximum diastolic pressure during sleep. Specifically a maximum diastolic arterial pressure (DAP) at ABPM during the period of night sleep ³64 mmHg presented an odds ratio of 6 for PH with a sensitivity of 80% and a specificity of 60% for the development of PH. CONCLUSION: The research for PH predictive factors in primiparous adolescents showed to be easy to apply and useful to stratify high-risk pregnant women as regards the development of PH.
