Cardiovascular Reactivity and Cardiovascular Risks Factors of in Normotense Individuals in the Municipality of Rodas, Cienfuegos, Cuba

Abstract

Background: A relationship exists between different cardiovascular risk factors and a significant rise in blood pressure in the presence of psychological or physical stress (cardiovascular reactivity). We studied this relationship in normotense individuals who were subjected to stress caused by isometric exercise, which provided us with proof of the amount of weight withstood. Methods: A descriptive study was conducted in which 267 normotense individuals were divided into two groups. One of these groups was a study group comprised of cardiovascular hyperreactive (CVHR) with a greater blood pressure response (BP)(n=58), with BP levels > 90/140 mm/Hg, and the other group as a control group, with BP<90/140 mm/Hg, n=209. The relationship was found between the age, gender, sedentarism, smoking habit (SH), alcoholic beverage intake (ABI) and clinical history of blood pressure disorders (CH of BPD with the condition of cardiovascular hyperreactivity. Results: 21.7% of the subjects were CVHR. The risk factors SH, ABI and gender were not related to the CVHR P>0.05. The risk factor of CVHR is twice as high on the part of sedentary individuals, age becoming a factor as of age 40, and those individuals with a CH of BPD had twice the risk of having a cardiovascular hyperreactivity 3.85 (2: 7, 19) as those who had no CH of BPD). Conclusions: A significant relationship exists between being over age 40, CH of BPD and lack of exercise with a CVHR condition. This was not found to be the case for other risk factors such as SH, gender and ABI.
