Animal models that focus solely on LV pressure/volume overload such as the Dahl-salt sensitive or spontaneously hypertensive rat, aortic banded cat, or aldosterone infusion – generate principally cardiac disease such as hypertrophy, diastolic dysfunction, and fibrosis. Pure obesity models, such as the leptin or leptin receptor deficient models (db/db or ob/ob) generate marked obseity and some cardiac disease. Other models such as L-NAME+high fat diet (HFD) in mice, or the DOCA-HFD pig model, or the senescence accelerated mouse on western diet (SAM-WD) attempt to integrate both components. The latter two do not develop significant heart failure however, reflected by less increase in diastolic pressure and fluid accumulation in the lungs.
