Hello Doc. I Am Antonio And I Have A Brother

Hello doc. I am antonio and i have a brother hes 18 years old .2nd year college student and saddenly after hs activity in school like TAEKWONDO he had chest pain, difficulty of breathing sometimes. We consult to the doctor then the docotor said he has a rheumatic heart desease then the docotor gives antibiotics. The X-RAY result is nothing wrong. This is the first time that my brother went to hospital he has no history of heart failure, even he never experienced colupse or something serious happen . Is it my brother really has a problem in hs heart? Or is it okay if my brother could take MX3 capsule in tea . Because rheumatic heart desease is a damage of valve and inflame. MX3 is an anti inflammatory . An 18 year old is okay to intake ths vitamins(MX3)
