Two concerning heart questions by 24 yr old

[Saylor23]

I have a concerning question I will give you a short history the. Move on to my question I'll make this short.

I'm 23 yrs old, male, 220, 6'3, I'm half African American/Caucasian, I'm into sports I workout 3 days a week play sports 3-4 days a week. I was diagnosed with hypertension and lvh(1.5) and pericarditus(3months ago)  about a yr ago on hypertension. I'm taking two Bp meds to keep Bp in 130/120-70/60 range.  I had a recent visit to the ER my EKG came back the said all looked normal no pericarditus or thickening showed.

My question is can lvh regress within a year from a 1.5 thickness....? Also is it a concern that I can feel my heart pulse when laying on my left side with or without touching it? Feels like it's right against my side?

Thank you for the detailed response.
You pretty much answered everything

I have took a arrest test almost two yrs ago, checked out normal, my Bp was not taken during my stress test only before activity was started I was pretty nervous and when I get nervous my heart pumps hard I have adrenaline that kicks in. it was like 164/80

Only other question I have is can Pericarditus look like Lvh on a echo? My lvh was concedered mild/moderate(cardiologist) then 4 months later my family doc said I had pericarditus(inflamed sack around the heart) showed on EKG...then 4 months after that I went to the er for pains they said all looked normal no signs of pericaritus or thickened heart? So I'm wondering if it can be mistaken as LVH?

According to the following, if the wall thickness is greater than 1.5 cm (15 mm or about 9/16 of an inch), then it's considered as LVH. Yours is 1.5, so by their definition, you're only borderline.

"An echocardiogram is the most common way to determine if a patient has LVH. This test allows your doctor to measure the walls of the ventricle. A measurement greater than 1.5 cm is considered enlarged. Patients with athletic hypertrophy usually have a measurement less than 1.5 cm, and the wall returns to normal size after exercising. If you do not have any of the typical causes of LVH and have a family history of HOCM, your doctor may determine that you have HOCM (Hypertrophic Obstructive Cardiomyopathy)."

There is blood pressure measured in the office or at home, representative of your pressure at rest or with minimal exertion, then blood pressures under exertion that can be much higher. If you have a strenuous job or exercise often, the exertional blood pressure may still be an issue. ACE Inhibitors and ARBs are two drugs used to reduce vascular resistance to blood flow, other drugs also may be used, such as Beta Blockers and Calcium Channel Blockers.

Avoiding caffeine and other vaso-constrictive medications, such as some cold medications, will help keep the blood pressure down. Being careful to minimize fat and cholesterol will help assure your vessels don't become excessively restricted with age.

I'm not familiar with Pericarditis, perhaps someone else can help. I'd ask the doctor about the feeling when lying on your side, but I don't believe it's that uncommon.
