Abstract.Uncontrolled high blood pressure is a major public health problem in Brazil, particularly among African-Brazilian people. Despite the advances related to the prevention and control of the disease, many clients are still suffering with the morbity or the mortality of the arterial hypertension and others present the risk factors related to cardiovascular diseases.

Introduction

The purpose of this article is to review the Brazilian current knowledge related to the nursing diagnoses and interventions related to the client presenting risk factors for high blood pressure, or with the disease. It is not intended to be an exhaustive review, but rather a brief review of the major nursing researches which form the basis for consideration of nursing roles and the nursing process in prevention and control of arterial hypertension.

Nursing research related to the client at risk for arterial hypertension

Every professional nurse must participate in activities directed toward the goal of prevention and control of high blood pressure. Early detection of high blood pressure is a primary goal for undetected populations.

CRUZ; LIMA (1998) studied the life style of 213 persons of the nursing staff to identify those who are at risk for high blood pressure. They concluded that many risk factors (contraceptive pill, salt, obesity, sedentarism, etc) are present in the population and they suggested the development of a nursing policy to the prevention of these problems.

Others researches related to historical aspects of cardiovascular risk factors (CRUZ, 1993; CRUZ et al, 1998) pointed out the colonial origins of our life style and diseases. Cruz et al (1998) suggested that the high blood pressure in the African Brazilian is an heritage of the slavery period and the process of acculturation. The NESEN - Núcleo de Estudos sobre Saúde e Etnia Negra (Health and Negro Etnicity), at the Fluminense Federal University, has the objective to study the african-brazilian and the aspects related to the cardiac risk factors and arterial hypertension.

But health promotion and prevention aren’t a major aspect of the Brazilian nursing researchers because the disease is the focus of our care and cure. Neither ethnicity and gender are major variables in our researchs, consequently women and African Brazilians are still having na unhealthy life stile and suffering with the morbi-mortality of high blood pressure and other cardiovascular diseases.


Nursing research related to the client with arterial hypertension
The Brazilian nursing research is more concerned with the control of the disease, its signs and symptoms (PIERIN, 1985; CRUZ, 1988; BRAGA; COVELLO, 1994).

With the advance of the international nursing classification program, the direction of the nursing research focus is changing to the phenomena presented by the client with arterial hypertension and the nursing interventions to these phenomena. CRUZ (1993a) identified the following nursing diagnoses: knowledge deficit (disease and treatment), anxiety, constipation, sexual dysfunction, and activity intolerance.

CRUZ (1994; 1995) observed that there isn’t a safe parameter for the nursing interventions directed to the diagnoses of the hypertensive client. She suggested that further researches should be developed to identify the nursing therapies and the criteria of evaluation for the resolution of these nursing diagnoses.

CRUZ et al (1995) proposed to include the family in the treatment of the client with arterial hypertension. The authors considered that the changes in  the life style affects not only the client and the risk factors may be present in the members of the family who would be susceptible for the disease.


Nursing research related to the measurement of blood pressure

The sphigmomanometry is a strong research area in Brazil, particularly at the University of São Paulo (PENICHE; ARCURI, 1992). Although these researches stress the importance of the technique to diagnostic and control of arterial hypertension, we can observe that the technique is neglected by the health professionals.

Conclusion
The Brazilian current knowledge related to the nursing diagnoses and interventions related to the client presenting risk factors for high blood pressure, or with the disease is still insipient.

The nursing research related to the client with arterial hypertension offers opportunities to reach undetected populations, particularly women and African-Brazilian. The nursing research should explore the engagement of the client in the health education activities, the development of screening for a referral nursing services, the nursing therapies for prevention of cardiac risk factors and control of arterial hypertension for individuals, families and groups.

But it is also necessary that the nursing practice utilizes an up-to-date knowledge base, the recommended standards for measurement techniques, and the implementation of detection and follow-up activities, which will expand the percentage of the population with a healthy life style and detected  and controlled blood pressure.
