First-line treatments
Comprehensive renal imaging
Periodic imaging studies including Doppler ultrasound to assess peritubular capillary blood flow and detect structural changes.
Renal disease management
Conservative management and lifestyle modifications may be sufficient. Monitor symptoms.
Endothelial-protective agents
Pharmacologic agents such as sulodexide or pentoxifylline that may improve microvascular blood flow and endothelial function.
Additional treatment options
Antioxidant-rich nutrition protocol
Dietary approach emphasizing foods rich in antioxidants and anti-inflammatory compounds to support microvascular health.
dietarySmoking cessation
Complete tobacco avoidance to eliminate vasoconstrictive and endothelial-damaging effects that worsen microvascular conditions.
lifestyleAngiotensin receptor neprilysin inhibitor therapy
Advanced pharmacologic approach using ARNI medications to provide comprehensive renal microvascular protection in appropriate candidates.
