DallasD,

Thanks for your question.

Blurred vision as you've described is not a typical symptom of heart disease.  I would be more concerned about a problem with blood pressure.  Should this prove to be OK, his physician should consider other causes for this problem.  The fact that it existed before his heart attack and improved with medication, seems to support a blood pressure situation. 

As you probably would agree, the one thing your boyfriend should not do is stop or alter the dose of any medication without the knowledge of his physician.  I understand that the heartburn was uncomfortable, but this should have been discussed with his physician.  If a medication change was not possible, medication could have been prescribed to counteract the heartburn.

It sounds as though he's undergoing changes that may indicate some deterioration.

Your boyfriend needs to make an appointment with his physician to be re-evaluated.  They need to go over his prior medications and discuss changes that would avoid his heartburn and avoid problems with sexual function.  These are common problems that doctors deal with every day, and patients should have no hesitation in discussing it with their physicians.

Please urge your boyfriend to make an appointment as soon as possible.

Best wishes.

Martin Cane, M.D.
