At two tables east simply raised the opening bid of 1D or 1H to the two level. This way understates the value of the hand.
The standard ACOL opening bid for west is 1D despite the poor quality suit (a bonus is if u end in NT oppo will probably not lead your weakest suit!).

West also shouldn't rebid 2H with only a 4 card suit. 2 NT is the appropriate bid.
Over a 1H opener by west, east should just bid game in hearts, show your 4 card suit directly.
Some partnerships have a convention called splinters, so here 1H 3C would show 4+ heart support, shortage in clubs and invite+ values. Pard can then see their QJ of clubs is useless and not get excited about slam prospects.
