dP/dt Response to MDMA and L-NAME Intervention - Clinical Cardiovascular Data #1444060 (License: Personal Use)

This bar chart illustrates the time-dependent effects of MDMA and its interaction with the nitric oxide synthase inhibitor L-NAME on left ventricular contractility, measured as normalized dP/dt (rate of pressure change). MDMA significantly increases contractility at 5 minutes compared to placebo, while co-administration with L-NAME attenuates this effect, suggesting nitric oxide modulation plays a role in MDMA-induced cardiac stimulation. Error bars represent standard error of the mean, and asterisks denote statistical significance.

Used in cardiovascular pharmacology research articles or clinical trial reports to demonstrate acute hemodynamic responses to psychoactive substances; targets researchers, clinicians, and students seeking mechanistic insights into drug-induced cardiac effects.
