I understand this might be a bit advanced given where we are in the program, but I have some questions about using positively inotropic herbs like Viscum album (mistletoe). Specifically, is it appropriate to use in cases of Left Ventricular Hypertrophy (LVH)? Does it make sense to use something like Viscum for someone with severe non-ischemic ( stable) angina? I’m concerned about the inotropic effects increasing the heart’s workload in someone with LVH, even though they don’t have a diagnosis of heart failure or any significant evidence of coronary disease. Thanks for any insight you can provide!

David said: Mistletoe is not used for LVH. It is only used for reducing blood pressure, not for overt cardiac issues. In an animal study it reduced blood pressure but did not affect heart rate. In general I would not consider it to have signifiant positively inotropic effects.
