Key result
Aminophylline increased stroke volume under normoxic conditions but had no positive inotropic effect and slightly decreased end-diastolic dimensions during hypoxia in dogs.
Why the study?
Does aminophylline improve left ventricular performance during hypoxic conditions in dogs?
Does aminophylline improve left ventricular performance during hypoxic conditions in dogs?
In a canine model, aminophylline lacks a positive inotropic effect and exerts a slightly negative diastolic effect on the left ventricle during hypoxia, contrasting with its beneficial effects during normoxia.

No benefit for hypoxic LV performance in dogs; leaves open translation to human hypoxemic states.
Gómez et al. (1988) studied Hypoxia. Aminophylline vs. Baseline (before infusion) was evaluated on Left ventricular (LV) mechanics and central hemodynamics. Aminophylline increased stroke volume under normoxic conditions but had no positive inotropic effect and slightly decreased end-diastolic dimensions during hypoxia in dogs.
