Key result
Nitroglycerin produced a greater fall in pulmonary capillary wedge pressure (25 to 15 mm Hg) than sodium nitroprusside (24 to 17 mm Hg; P<0.05) in complicated acute myocardial infarction.
Why the study?
Does intravenous sodium nitroprusside or nitroglycerin improve hemodynamic parameters in patients with complicated acute myocardial infarction?
Does intravenous sodium nitroprusside or nitroglycerin improve hemodynamic parameters in patients with complicated acute myocardial infarction?
p-value: p=<0.05
In complicated acute myocardial infarction, nitroglycerin produces more potent venodilatation and a greater reduction in left ventricular filling pressure compared to sodium nitroprusside, which has a more balanced effect on arterial and venous circulation.

Nitroglycerin may offer greater preload reduction than nitroprusside in complicated AMI; hypothesis-generating and should not yet change practice.
Armstrong et al. (1975) studied complicated acute myocardial infarction (n=26). Nitroglycerin (GTN) vs. Sodium nitroprusside (NP) was evaluated on pulmonary capillary wedge pressure (PCW) (p=<0.05). Nitroglycerin produced a greater fall in pulmonary capillary wedge pressure (25 to 15 mm Hg) than sodium nitroprusside (24 to 17 mm Hg; P<0.05) in complicated acute myocardial infarction.
