Key result
Aminophylline transiently improved cardiac index and pulmonary vascular resistance but increased heart rate and decreased stroke volume, failing to improve overall cardiac function.
Why the study?
Does aminophylline improve right heart function in a porcine model of right heart infarction?
Does aminophylline improve right heart function in a porcine model of right heart infarction?
In a porcine model of right heart infarction, aminophylline did not improve overall cardiac function despite transient reductions in right heart afterload.
No takes yet. Share an insight, caveat, or question.
No net benefit in porcine right infarction cautions against clinical use; leaves open translation to human right heart failure.
Spalding et al. (2000) studied Right heart failure / Right heart infarction (n=17). Aminophylline vs. Control pigs was evaluated on Right heart function (cardiac index, pulmonary vascular resistance, heart rate, stroke volume). Aminophylline transiently improved cardiac index and pulmonary vascular resistance but increased heart rate and decreased stroke volume, failing to improve overall cardiac function.
