TNF and Hypertension: We found that low eGFR, hypertension, smoking status and history of atrial fibrillation were significantly associated with elevated TNFα levels, while elevated TNFR1 levels were associated with aging, low eGFR, hypertension, diabetes and PVD, and elevated TNFR2 levels were associated with aging, low eGFR, diabetes and atrial fibrillation.
