Can I use Maxigra Go by taking Polsart constantly?

I guess that you mean Polsart Plus in a dose of 80 mg + 25 mg, because the trade name you mentioned is not compatible with any preparation currently available on the market. There are no contraindications to the simultaneous use of Maxigra Go together with the above-mentioned drug. However, it is worth remembering that in people with some cardiovascular diseases, i.e. unstable angina or severe heart failure, it is contraindicated. Without more information about the state of health, I am not able to answer unequivocally whether you can safely use Maxigra, so I recommend informing the cardiologist about your intention to take it.
