Korábbi kezelés

• Systolic BP meeting any of the following criteria: A) Current office systolic BP \<100 mmHg; B) Current office systolic BP 100-119 mmHg if not receiving treatment with an antihypertensive agent or if holding antihypertensive medication prior to randomization would be clinically contraindicated, as per the investigator's clinical judgement; C) Current office systolic BP ≥180 mmHg if not receiving treatment with a CCB or β-blocker, or ≥160 mmHg if already receiving a CCB and/or β-blocker prior to the pre-randomization wash-out period; D) Orthostatic hypotension defined as \>20 mmHg decline in office systolic BP 3-5 minutes following the transition from sitting to standing position
• Contraindication to withholding CCB or β-blocker therapy (e.g. use of non-dihydropyridine CCB \[diltiazem or verapamil\] or β-blocker for rate control for atrial fibrillation) as per the investigator's clinical judgement
• Clinically significant lung disease, defined as any of the following: A) Chronic Obstructive Pulmonary Disease meeting GOLD criteria stage III or greater; B) Treatment with oral steroids within the past 6 months for an exacerbation of obstructive lung disease; C) The use of daytime supplemental oxygen

Más betegség

• Resting heart rate \<50 or \>100 bpm
• Active coronary artery disease, defined as any of the following: A) Acute coronary syndrome or coronary intervention in the past 2 months; B) Ischemia on stress testing without either subsequent revascularization or a subsequent angiogram demonstrating the absence of clinically significant epicardial coronary artery disease, as per investigator judgement
• Any medical condition that, under the investigator's discretion, will interfere with safe completion of the study or validity of the endpoint assessments
• Known history of an allergy or clinically significant sensitivity (as determined by the investigator) to either amlodipine besylate or metoprolol succinate

Laborértékek

• Any the following echocardiographic findings: A) LV ejection fraction \<45% on any prior echocardiogram, unless it was in the setting of uncontrolled atrial fibrillation; B) Hypertrophic, infiltrative, or inflammatory cardiomyopathy; C) Clinically significant pericardial disease, as per investigator judgment; D) Moderate or greater left-sided valvular disease, any degree of mitral stenosis, or prosthetic mitral valve; E) Severe right-sided valvular disease; F) Severe right ventricular dysfunction
• eGFR \<30 mL/min/1.73m2
