Key result
Intracoronary Angiotensin II infusion produced no significant changes in systolic and diastolic function or coronary vascular resistance in anesthetized pigs.
Why the study?
Does intracoronary Angiotensin II infusion affect local cardiac function and coronary vascular tone in anesthetized pigs?
Does intracoronary Angiotensin II infusion affect local cardiac function and coronary vascular tone in anesthetized pigs?
p-value: p=ns
Local intracoronary infusion of Angiotensin II does not directly alter cardiac function or coronary vascular tone in a porcine model, indicating that previously observed inotropic effects are likely mediated via extracardiac mechanisms.
No takes yet. Share an insight, caveat, or question.
No direct cardiac effects in porcine model; leaves open extracardiac mediation and requires confirmation in other species before clinical inference.
Broomé et al. (2002) studied Cardiac function and coronary vascular tone (n=9). Intracoronary Angiotensin II infusion was evaluated on Cardiac systolic and diastolic function and coronary flow (p=ns). Intracoronary Angiotensin II infusion produced no significant changes in systolic and diastolic function or coronary vascular resistance in anesthetized pigs.
