Future medication and persistent cough.

I had my stent fixing in Aug end 2021 after a silent attack which I came to know after angio when I had gone to doctor for loose motion. I have been given a list of 8 different medicines of Nexium 40mg, aspirin 100mg, concor 5mg, coveram 5mg, lipitor 80mg, aldactone 25mg, forxiga 5mg, brillianta 90mg and been asked to continue for a year. In November I went for consulting and the check found 52% heart pump recovery in 3 months time. I used to be smoker but stopped after my stent fixing. I have regular habits now, no drinking no party and no late night. I work 9-6 but heavy mental workload. Last 2 month I am having severe cough. My question a) what can I do to stop cough b) I want to reduce/stop these medicines. Pls help. Happy to provide anymore info if required.
