Background: The impact of hypertension on symptoms and functional capacity during exercise treadmill test (ETT) in apparently asymptomatic patients with aortic stenosis is poorly understood.

Methods: A total of 314 patients (age 65 ± 12 years, 68% men) with moderate or severe asymptomatic aortic stenosis underwent baseline echocardiography and ETT. Hypertension was defined as a history of elevated blood pressure (BP), past or current treatment with antihypertensive agents or a BP at the baseline clinic visit more than 140/90 mmHg.

Results: There were 229 (73%) patients with hypertension who were older, more likely to have diabetes, hypercholesterolemia and coronary artery disease, larger left atrial diameters, higher left ventricular (LV) mass and a higher proportion of LV hypertrophy than normotensive patients. In a univariate logistic regression analysis hypertension and clinic SBP were not associated with revealed symptoms. In a multivariate logistic regression analysis, lower peak SBP [odds ratio (OR) 1.02;95% confidence interval (CI) 1.00–1.04, P = 0.017] and rapid early rise in heart rate (OR 15.03; 95% CI 6.23–36.24, P < 0.001) were associated with a higher risk of revealed symptoms while the use of antihypertensive treatment was associated with a lower risk of revealed symptoms (OR 0.40; 95% CI 0.18–0.89, P = 0.025), independent of age, obesity, LV ejection fraction and aortic valve area. In a linear regression analysis, after adjustment for age, sex and BMI, hypertension did not retain an association with lower metabolic equivalents (β = −0.06, P = 0.311).

Conclusion: Hypertension in aortic stenosis patients was associated with a high cardiovascular disease burden, but did not interact with symptoms or functional capacity during ETT. Hypertension does not interfere with the clinical interpretation of exercise testing.
