ASSOCIATION BETWEEN BLOOD VISCOSITY AND CARDIOVASCULAR RISK FACTORS IN PATIENTS WITH ARTERIAL HYPERTENSION IN A HIGH ALTITUDE SETTING

Background Blood viscosity is a determinant of vascular resistance, and it is expected to contribute to blood pressure. Arterial hypertension (HTN), in addition to other cardiovascular risk factors, contribute to cardiac morbidity. Our study aimed to establish the association between cardiovascular risk factors including HTN and whole blood viscosity in Ecuadorian patients. Material and methods We studied 132 patients with the diagnosis of HTN. Fifteen cardiovascular risk factors were analyzed. The association between whole blood viscosity (WBV) and the number of cardiovascular risk factors was studied. The association between blood viscosity and risk factors was analyzed. Results One hundred and thirty-two patients were analyzed. Blood viscosity was associated with a number of cardiovascular risk factors. Creatinine, uric acid, total cholesterol, and low-density lipoprotein (LDL) values were significantly higher in patients with high blood viscosity. Conclusion Blood viscosity is a physiological variable associated with a number of cardiovascular risk factors in hypertensive patients.
