I agree with everything you've said about cardiac output. It is the primary equation when determining the adequacy of overall cardiac function. I brought up ejection fraction specifically because it's vital in the diagnosis, as well as the long term prognosis of those people who are affected by either a dilated, hypertrophic, or restrictive cardiomyopathy pathology.
The kidneys are most definitely overlooked in their role of fluid and blood pressure management. ACE inhibitors have come a long way in hypertensive management.....especially those with a prior cardiac histroy.
BTW - Great convo, lake.
I really do enjoy threads of this nature. Not only are the informative and interesting for all involved and observing, but they provide a great intellectual stimulus environment.
