Popis: The factors which contribute to an exaggerated blood pressure response (EBPR) during the exercise treadmill test (ETT) are not wholly understood. The association between the insertion/deletion polymorphisms of the angiotensin-converting enzyme (ACE) and M235T of the angiotensinogen with EBPR during ETT still remains unstudied. To identify and compare the risk factors for hypertension between normotensive subjects with EBPR and those who exhibit a normal curve of blood pressure (BP) during ETT. In a series of EBPR cases from a historical cohort of normotensive individuals, a univariate analysis was performed to estimate the association of the studied factors with BP behavior during ETT. Additionally, logistic multivariate regression was conducted to analyze the joint effects of the variables. P-values above 0.05 were considered statistically significant. From a total of 10,027 analyzed examinations, only 219 met the criteria employed to define EBPR, which resulted in a prevalence of 12.6%. For the systolic component of the BP, hyperreactive subjects displayed a mean age and body mass index (BMI) significantly higher than the others (P=0.002 and
