That's good news. The absence of proteinuria would provide further reassurance.
I personally do not think you need special precautions. I would maintain a healthy life-style (exercise as tolerated, avoid smoking at all costs, maintain good cholesterol and body weight). The one medical factor that should be monitored is your blood pressure. Salt reduction, the use of losartan/amlodipine/bisoprolol, healthy lifestyle factors listed above will all help. The target blood pressure you should achieve is something to discuss with your physician as there would be some pros and cons to go over. Finally, your creatinine levels should be monitored, as they have, to ensure stability.
All the best,
