WebAbstract From growing data from the literature emerges that so-called ecoDoppler "Renal" Resistive Indexes (RRI) are not only specific markers of kidney damage and indicators of renal functional prognosis but they always express more clearly a strong link with the systemic circulation. WebJan 31, 2024 · The renal resistive index has been demonstrated to predict the progression of renal disease and recurrence of major cardiac events in high‐risk cardiovascular patients, in addition to other comorbidities. We aimed to assess the prognostic significance of the renal resistive index in type 2 diabetic patients for primary prevention. Web• High resistive index – muscular arteries (eg. superficial femoral artery, posterior tibial artery, common femoral artery, external carotid artery) • Low resistive index – arteries feeding organs that need flow even during diastole (internal carotid artery, renal artery, testicular artery, babies, tumors) Normal RI = 0.6 – 0.7 plastic motorcycle fuel tank
