Objective:
To determine the frequency of white-coat hypertension (WCH) and associated risk factors in recently diagnosed hypertensive patients.
Material And Methods:
A cross-sectional study was carried out from January 1997 to December 1998. The reference population consisted of 195 patients presenting with systemic arterial hypertension (SAH) of less than 1-month evolution and receiving no medical treatment. According to Joint National Committee (JNCVI) criteria, 100 individuals with Stages I, II, and III SAH underwent the following procedures: clinical history; physical examination; electrocardiogram, serum creatinine; urianalysis, and ambulatory monitoring of arterial pressure (AMAP).
Results:
A total of 54% of patients were WCH carriers and 46% presented sustained hypertension (SH); 37% of WCH patients and 63% of SH patients had a family history of SAH, while 19.7% of WCH patients and 39.2% of SH patients presented with stage 1 retinopathy. Left ventricular hypertrophy was absent in all WCH patients and present in 21.7% of SH patients. A total of 31% of WCH patients and 50% of SH patients presented electrocardiographic changes.
Conclusions:
A total of 54% of patients presented WCH. Clinical/epidemiologic profiles of WCH carriers and SH patients are different.

Factors affecting Blood pressure
Physiological Factors:
Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
