ABSTRACT The pulse pressure (PP) has been considered in recent years one cardiovascular risk factor independent and a marker of cardiovascular mortality and total. Objective: To determine the relationship between pulse pressure and the severity of hypertensive retinopathy in patients with hypertension of UAH¿s CECREFAL. Metodos: A cross-sectional study. In 96 hypertensive patients attending the consultation of hypertension in CECREFAL been made ambulatory monitoring of blood pressure (BP) for 24 hours (MAP) and fund eye, determining the degree of retinopathy as classified by Keith Wagener. Results: We included 96 hypertensive patients with a mean age of 56 ± 14 years old, 61.4% were fema¬le and 38.5% were male. The tercil 1 (12-51 mmHg) was presented in 38.5%, tercil 2 (52-65 mmHg) in 25% and tercil 3 (>= 66 mmHg) in 36.5% of patients studied. In 83.33% of the patients was observed retinopathy, grade I in 41.7% and grade II in 37.5%. Increasing levels of pulse pressure is associated with increased incidence of retinopathy. Conclusion: The control of the PA with MAP best predicts future cardiovascular events and the impact on the target organs, which determinations of casual BP. There relationship between pulse pressure and degree of retinopathy in our midst, however, studies are needed to confirm globally, previous findings that relate the increase in DB impact with early target organs, specifically with retinopathy.

    ABSTRACT: Objetivo: Avaliar a prevalência de retinopatia hipertensiva (RH) em pacientes hipertensos (controlados e não controlados) e normotensos na população acima dos 40 anos do município de Piraquara. Correlacionar os casos de alteração retiniana com o sexo, a raça e a idade do paciente. Métodos: Durante 1998 e 2000, foram examinados no Projeto Glaucoma da Universidade Federal do Paraná 1.954 pacientes. Destes, excluíram-se aqueles abaixo de 40 anos e os diabéticos, sendo que a população considerada para este estudo foi de 1.741 pacientes. O protocolo do projeto consiste de anamnese direcionada, aferição da pressão arterial (PA), glicemia por tiras reativas, PIO e fundoscopia direta e indireta. As alterações fundoscópicas pertinentes a retinopatia hipertensiva foram estudadas segundo a classificação de Gans e correlacionadas conforme mencionado anteriormente. Resultados: Dos 1.741 pacientes analisados, 669 (38,43%) são hipertensos, 645 (37,05%) normotensos e 427 (24,53%) suspeitos de hipertensão arterial sistêmica (HAS). Foram encontrados 211 (12,12%) pacientes com sinais de RH, sendo 136 (64,46%) do sexo feminino e 75 (35,54%) do sexo masculino; 134 (63,98%) de 40 a 60 anos e 77 (36,02%) com idade superior a 60 anos; predominando as raças branca (75,83%) e negra (11,37%). Do total de pacientes com RH, 154 (73%) eram hipertensos, 17 (2,64%) normotensos e 40 (9,37%) suspeitos de HAS. Dentre os hipertensos com PA controlada, 12,2% apresentavam sinais de retinopatia. Já dentre os hipertensos com PA não controlada, 25,3% apresentavam sinais da patologia. Conclusão: A prevalência de RH foi maior nos hipertensos comparativamente aos normotensos e suspeitos de HAS (p<0,001, OR=5,32). Os pacientes negros (p<0,05 e OR= 1,67), os hipertensos com PA não controlada (p<0,01, OR=2,44) e os acima de 60 anos (p<0,001, OR=1,85) apresentaram maiores chances de desenvolverem RH.

    ABSTRACT: The objective was to investigate the relationship of systemic hypertension to the incidence of various retinal vascular lesions in the population-based Beaver Dam Eye Study. Subjects aged 43 through 86 years who lived in Beaver Dam, Wisconsin between 1987 and 1988 were examined between 1988 and 1990 and 5 years later, 1993-1995. Blood pressure was measured using standardized protocols. Stereoscopic color fundus photographs were graded in a masked fashion using standardized protocols to determine the presence of retinopathy (blot hemorrhages, microaneurysms, hard and soft exudates, intraretinal microvascular abnormalities, and venous beading), retinal arteriolar narrowing, and arterio-venous nicking. People with diabetes or retinal vascular occlusions were excluded from the analyses. Among those examined, 2,151 (69.1%) were normotensive and 963 (30.9%) were hypertensive at baseline. Over the five-year period, retinopathy developed in 175 (6.0%), arteriolar narrowing in 282 (9.9%) and arterio-venous nicking in 201 (6.5%) nondiabetic subjects. After adjusting for age, hypertension was associated with the incidence of retinopathy (in men: relative risk [RR] 2.31, 95% confidence interval [CI] 1.54 to 3.48; in women: RR 1.61, 95% CI 1.07 to 2.43) and with arteriolar narrowing (in men: RR 1.82, 95% CI 1.25 to 2.66; in women: RR 1.36, 95% CI 1.05 to 1.77), but not with arterio-venous nicking (in men: RR 1.01, 95% CI 0.69 to 1.48; in women: RR 1.37, 95% CI 0.95 to 1.97). The five-year incidence of retinopathy and of arteriolar narrowing was higher in those subjects whose blood pressure was elevated despite use of antihypertensive medications compared with those subjects whose blood pressure was controlled with antihypertensive medications or those who were normotensive. These data show a relation of hypertension to an increased incidence of retinopathy and arteriolar narrowing. Furthermore, these data suggest that pharmacologic control of blood pressure is related to a lower incidence of these anatomic retinal lesions relative to uncontrolled blood pressure.
