Key result
Uncontrolled hypertension is linked to worse RV function and reduced exercise capacity versus controlled hypertension.
Why the study?
The relationship between right ventricular function assessed by transthoracic echocardiography and exercise capacity in patients with arterial hypertension was not well established.
Is right ventricular function and exercise capacity reduced in patients with untreated or uncontrolled hypertension compared to those with well-controlled hypertension?
Cross-Sectional (n=90)
Is right ventricular function and exercise capacity reduced in patients with untreated or uncontrolled hypertension compared to those with well-controlled hypertension?
Untreated or uncontrolled hypertension is associated with significantly reduced right ventricular function and exercise capacity compared to well-controlled hypertension.

RV dysfunction associated with reduced exercise capacity in hypertension; leaves open whether TTE assessment improves risk stratification.
Background: Transthoracic echocardiography (TTE) would be used to evaluate right ventricular (RV) function in patients with arterial hypertension, and the link between RV dysfunction and exercise capacity was studied in the study population. Objective: To establish a correlation with exercise capability in the study group by using transthoracic echocardiography (TTE) to evaluate RV function in patients with arterial hypertension. Patients and Methods: Patients with hypertension were surveyed in a cross-sectional research; those known and treated; whether controlled or not and patients who were recently discovered to be hypertensive. Ninety patients were included; gender and age were taken into account. A thorough examination was performed on each patient (TTE) as well as six minute walking distance (6MWD). For all we had a written informed consent prior to enrollment. Results: Patients with untreated and uncontrolled hypertension showed significantly reduced right ventricular systolic and diastolic functions compared to those with well-controlled hypertension. Patients with untreated or uncontrolled hypertension had significant (P <0.001) deterioration on S', wave and diastolic dysfunction parameters (E/A, DTt, E/e t and IVRT). Untreated and uncontrolled hypertension patients showed a significant decrease in 6MWD compared to the well-controlled individuals (P <0.001). Conclusion: Untreated or ineffectively treated hypertension individuals had considerably reduced right ventricular function and exercise capacity, according to our findings. In the entire research population, right ventricular functions are strongly linked to exercise ability.

Mahfouz et al. (2021) conducted a cross-sectional in Arterial hypertension (n=90). Untreated or uncontrolled hypertension vs. Well-controlled hypertension was evaluated on Right ventricular systolic and diastolic functions and 6-minute walking distance (6MWD) (p=<0.001). Untreated and uncontrolled hypertension was associated with reduced right ventricular function and decreased 6-minute walking distance compared to well-controlled hypertension.
