Can my height and weight play a role in aortic regurgitation?

Hello doctor,

I am 57 years old. I had a recent echocardiogram to monitor my moderate aortic regurgitation and mildly dilated aortic root and ascending aorta of 41 mm. Both remained stable. My rest echo report indicated the following such as normal left ventricular size, overall low normal systolic function with and EF of 54, LV FS equals 27%, no resting regional wall abnormalities, spectral doppler shows impaired relaxation pattern of LV diastolic filling and indeterminate LV filling pressure with E/A ratio equals 8, normal right ventricle size, wall thickness, and systolic function RVS equal 15 cm, mildly dilated left atrium of 23 cm2, normal right atrium, normal pericardium, tricuspid aortic valve with localized prolapse of the anterior half of the right coronary cusp resulting in eccentric posterolaterally directed aortic regurgitation with no evidence of stenosis; PPG of 12mmHg; moderate aortic regurgitation 2-3/4; resting LVOT SV equals 125 mL Indexed equals 62 mL/m2, mild regurgitation of mitral and tricuspid valves 1/4, and normal pulmonary artery systolic pressure. RVSP equals 31 mmHg. My questions are as follows. My height, weight, and body surface area are 5' 4" feet, 211 pounds, 2.03 m2. l am actually 5' 9" tall and was wondering if this affects the measurements in any way? My cardiologist wants to see me in a year for a follow-up echo and does not think I will need a new valve in the short term. Does this seem reasonable? I am 57 years old and am wondering if I should be worried about the reference to impaired relaxation pattern of LV diastolic filling. I am currently on Atenolol 100 mg, Crestor 40 mg, and Effexor 75 mg. Please help.

Thank you doctor,

Is ejection fraction of 54 normal? There is so much information on the internet saying that 55 is the threshold marker for normal. This worries me a little.
