First, it may take longer than just 5 days of medicine to improve. I would give the medicine a little longer to work. Second, the cough and wheezing may never go away completely. If the heart is enlarged, it could be pushing on the trachea which could be part of the reason for the cough. Also, a collapsing trachea will get worse the more excitable she becomes. If she isn't improving, I would have your vet reassess her 10-14 days after the medicine has been started. If she is getting worse, I would have your vet recheck her immediately. Your vet may want to take x-rays to see if there is any improvement in the lungs to see if the meds are helping some. They may decide to adjust the meds or add in something to help keep her calm and help with the collapsed trachea. Again, you cannot cure the enlarged heart. You also cannot cure the collapse trachea without surgery which doesn't have a great success rate. Keep a close eye on her. I hope this helps!
