Exploration of Manidipine to Reverse Aortic Valve Calcification

study will enrol 100 adults aged 60 to 85 years with MDCT-confirmed mild-to-moderate aortic valve calcification (Agatston score 300-2 000 AU) and preserved left-ventricular ejection fraction to receive manidipine 10 mg, manidipine 20 mg, or matched placebo once daily for 12 months, followed by a 3-month safety observation, with the primary endpoint being the absolute and relative change in aortic valve calcium score at 12 months; secondary endpoints include echocardiographic valve area and transvalvular gradients, six-minute walk distance, peak oxygen uptake, and comprehensive safety outcomes
