Key result
Angiotensin II infused at subpressor levels induced significant microvessel growth and its maintenance at normal levels eliminated rarefaction during hypertension or high-salt diet in rats.
Why the study?
Does Angiotensin II modulate microvessel density and prevent rarefaction in rats during high-salt diet and hypertension?

No immediate change to hypertension care; leaves open whether Ang II preserves microvessels in humans.
Does Angiotensin II modulate microvessel density and prevent rarefaction in rats during high-salt diet and hypertension?
Angiotensin II plays a critical role in maintaining the microcirculation, with its presence preventing the microvessel rarefaction typically seen in low-renin hypertension and high-salt diets.
Andrew S. Greene (1998) studied Hypertension and high-salt diet (animal model). Angiotensin II was evaluated on Microvessel growth and rarefaction. Angiotensin II infused at subpressor levels induced significant microvessel growth and its maintenance at normal levels eliminated rarefaction during hypertension or high-salt diet in rats.
