VALENCE: Valsartan Versus Atenolol on Exercise Capacity in Hypertensive Overweight Postmenopausal Women

A 26-week Double-blind, Randomized, Multicenter Parallel-group Trial to Compare the Effects of Valsartan Versus Atenolol on Exercise Capacity in Hypertensive Overweight Postmenopausal Women With Impaired Exercise Tolerance

The purpose of the study is to show that valsartan compared to atenolol has favorable effects on exercise capacity, quality of life, diastolic function and elevated blood pressure in hypertensive postmenopausal overweight women with impaired exercise tolerance despite normal left ventricular ejection fraction (LVEF).

Inclusion Criteria:

• Body mass index (BMI) must be ≥ 27 and < 35
• Symptoms of impaired exercise capacity (e.g. who report shortness of breath on exertion when questioned) reported at Visit 1 or patients who have a history of shortness of breath which improved under diuretic therapy
• LV ejection fraction must be > 45% measured by echocardiography at Visit 2.
• Impaired exercise capacity measured by VO2max at Visit 4:

VO2max >14 and < 22 ml ⋅kg-1 ⋅min-1

Exclusion Criteria:

• Mean sitting diastolic blood pressure (MSDBP) ≥ 110 mmHg and/or Mean sitting systolic blood pressure (MSSBP) ≥ 180 mmHg
• LVEF ≤ 45 %
• Inability to completely discontinue all previous antihypertensive medications safely for the duration of the study
• Heavy smokers (>20 cigarettes/day)
