    Hi all,

    Does anyone know why it is beneficial in heart failure patients to decrease preload on the heart? I've been searching for a while and can't seem to find an answer.

    Thanks!

    Thanks for the thoughts. No idea how they relate to my question though.

    http://en.wikipedia.org/wiki/Preload_(cardiology)

    Would high preloads damage the heart, is that it? How do they damage it?

    If anyone knows I would really appreciate your help!!!

    The word “medicine” has existed for millennia and has described treatments or remedies for illnesses. The term “Health Medicine” was chosen to characterize a paradigm based primarily on wellness and prevention, but one that could also include a wide variety of therapies for treatment when needed.

    The replies are smokin' .. hehehehe


    What do you mean by preload ?

    Is this a correct rephrase of your question: Is it beneficial to reduce the load of the heart if has suffered from failures such as stroke, heart enlargement, and etc..?

    ok, let me try and put this one to rest.

    The preload puts a greater strain on the individual myocytes as there will be a greater force to push against for contraction of these muscles. (also due to the congestion the preload can be higher than normal anyway).
    The response of the myocytes is to hypertrophy to exert a greater force in order to manage this load. However in doing so, this actually decreases the efficiency of the heart leading to thickening of the septa, cardiomegaly and further progression of the condition.
    If you reduce the preload, this will prevent (in the short term as heart failure is progressive) the hypertrophy and enlargement of the heart.
    There are many drugs which contribute to reducing the preload as you may know such as beta blockers and ACE inhibitors and diuretics which all do so by indirect mechanisms.

    COOLEJ: heart failure is not necessarily due to an MI, but is not caused at all by a stroke, enlargement of the heart is part of heart failure.

    Right. Stroke should've been striken out of there.

    Got a question though: Would decreasing preload mean no physical exercise? Or maybe just the light exercises?

    No that would more be baseline stuff, when referring to the preload, exercise does cause a reactive increase in blood pressure while you are actually active, but the changes in the vascular bed, skeletal muscles and gaseous exchange etc make it more beneficial on the whole as there is greater efficiency of the body when you exercise. This can actually cause a fall in your blood pressure at rest. There are loads of studies demonstrating that exercise improves survival and even symptoms in heart failure.

    You'd be more worried about your resting blood pressure being high as it is a long term condition, than about transient increases when you exercise.

    *Assuming you understand the link of blood pressure/preload etc in haert failure!, if not just think of them as the same thing; hypertension is a risk factor for left heart failure, (I can explain if you need.)
