Clinical Trial – Cardiovascular Response to Exercise in Hypertension (ASSECURE) – Hypertension

Arterial hypertension (AH) is an important clinical social and economic problem, related to the increased cardiovascular risk. AH is associated with cardiovascular hemodynamic alterations, including left ventricular diastolic dysfunction (LVddf). In consequence of increased blood pressure, the effectiveness of LV as a blood pump decreases and the symptoms of heart failure (HF) may occur. Thus, the identification of noninvasive markers related with the progression from the asymptomatic AH to LVddf/HFpEF would be beneficial.

Another issue is that the diagnostic difficulties in patients with LVddf and HFpEF stem from the limited possibility to assess the hemodynamic response to exercise. Thus, there is a need for more detailed methods of cardiovascular monitoring while exercise testing.

We hypothesize that some new noninvasive hemodynamic parameters, characterizing left ventricular (LV) function and arterial stiffness, may help to predict the risk of cardiovascular events and future occurrence of LVddf/HFpEF. Moreover, we assume that cardiopulmonary exercise test (CPET), completed with new methods of noninvasive hemodynamic monitoring (impedance cardiography and applanation tonometry), would provide additional value in the assessment of the cardiovascular hemodynamic response to exercise.

The study is intended to verify these hypothesis.
