Key result
Propofol did not significantly modify intrinsic myocardial contractility in normal hamsters or those with hypertrophic cardiomyopathy.
Why the study?
Does propofol affect intrinsic myocardial contractility in hamsters with hypertrophic cardiomyopathy compared to normal hamsters?
Population
Left ventricular papillary muscles from normal hamsters and hamsters with hypertrophic cardiomyopathy
Comparison
Propofol (1, 3, and 10 micrograms.ml-1) in vitro vs Normal hamsters and baseline contractility

Propofol spares contractility in HCM models; leaves open relevance to clinical use in cardiomyopathy.
Does propofol affect intrinsic myocardial contractility in hamsters with hypertrophic cardiomyopathy compared to normal hamsters?
Propofol does not significantly modify intrinsic myocardial contractility in normal or cardiomyopathic hamsters in vitro, suggesting it may lack direct myocardial depressant effects in this setting.
Riou et al. (1995) studied Hypertrophic cardiomyopathy. Propofol vs. Normal hamsters was evaluated on Intrinsic contractility of left ventricular papillary muscles. Propofol did not significantly modify intrinsic myocardial contractility in normal hamsters or those with hypertrophic cardiomyopathy.
