Why the study?
Numerous experimental rat studies have examined how lifestyle factors and supplements affect the development of unilateral renovascular hypertension, prompting a synthesis of these risk factors.
Do lifestyle factors such as dietary supplements and physical activity affect the development of experimental unilateral renovascular hypertension in rats?
Do lifestyle factors such as dietary supplements and physical activity affect the development of experimental unilateral renovascular hypertension in rats?
In a rat model of renovascular hypertension, potassium and antioxidants reduce hypertension severity, while caffeine exacerbates it and physical activity lowers blood pressure but increases myocardial hypertrophy.

May inform preclinical URH models; leaves open translation of supplements, activity, or melatonin to human renovascular hypertension.
Background . According to WHO controllable hypertension risk factors include an unhealthy diet, physical inactivity, and wrong daily routine. To date, a large number of experimental studies in rats have studied the effect on the development of unilateral renovascular hypertension (URH) of dietary supplements (minerals, vitamins, flavonoids, caffeine, fats, carbohydrates), physical activity and melatonin therapy. Objective . To conduct a meta- analysis of studies on risk factors for the development of URH. Design and methods . The search for publications was carried out in the PubMed, Scopus, Google Scholar databases. A total of 52 publications were selected. Results . The severity of hypertension decreases when the diet is enriched with potassium, as well as with various antioxidants (vitamin C, flavonoids, melatonin), which reduce oxidative stress in the ischemic kidney. In addition, physical activity can help reduce blood pressure in URH, but at the same time, it increases myocardial hypertrophy. There was no hypertensive effect of increased sodium chloride intake in renal artery stenosis, and no effect of calcium or magnesium supplementation on the URH development. At the same time, caffeine intake significantly increases plasma renin activity and blood pressure in URH. Conclusion . The majority of experimental studies included in our meta-analysis investigated the influence of factors on the development of URH, but not their effect on blood pressure in the chronic stage of URH.
