This system was created on the basis that ischemia and angiographic disease patterns are not the sole determinants of amputation risk. [67] The WIfI classification system is broken up into two parts: wounds and ischemia. Wounds are graded 0 through 3 based on the presence of ulceration, gangrene, and ischemia. [66] Grade 0: no ulcer, no gangrene
Minoxidil possesses alpha 2-adrenoceptor agonist activity, [36] stimulates the peripheral sympathetic nervous system (SNS) by way of carotid and aortic baroreceptor reflexes. Minoxidil administration also brings an increase in plasma renin activity, largely due to the aforementioned activation of the SNS .
