Key result
Percutaneous transluminal coronary angioplasty significantly increased plasma BNP to a peak concentration of 66.1 pg/ml at 24 hours, whereas diagnostic coronary angiography did not.
Why the study?
Does transient myocardial ischemia induced by PTCA increase plasma BNP concentrations in patients undergoing coronary procedures?
Observational (n=79)
Does transient myocardial ischemia induced by PTCA increase plasma BNP concentrations in patients undergoing coronary procedures?
Absolute Event Rate: 66.1% vs 33.7%
Transient myocardial ischemia induced by PTCA balloon inflation causes a significant, transient increase in plasma BNP levels at 24 hours.
No takes yet. Share an insight, caveat, or question.
Transient ischemia raises BNP; provides first direct evidence of release beyond infarction.
Tateishi et al. (2000) conducted an observational in Transient myocardial ischemia (n=79). Percutaneous transluminal coronary angioplasty (PTCA) vs. Diagnostic coronary angiography was evaluated on Plasma BNP concentration at 24 hours. Percutaneous transluminal coronary angioplasty significantly increased plasma BNP to a peak concentration of 66.1 pg/ml at 24 hours, whereas diagnostic coronary angiography did not.
