What harmful effects does artery high pressure of lung produce to the heart? 's general knowledge
The increase of the pressure in the lung artery, has not merely limited from heart to dirty blood flow of lung, and in order to resist the pressure of this kind of increase, the heart has to strengthen the blood of pump, in order to continue providing the blood flow for other part of body to the lung dirtily and subsequently, it, through increasing the volume of every muscle cell, attempts to meet this kind of situation, the heart increases gradually, especially the right side heart (the blood of pump enters the dirty side of lung) . However, it is long, the myocardium cells of the right heart are excessively spread but can't shrink effectively, losing the normal ability to work under this lasting high pressure finally, we call the congestive right heart depletedly. It is terminal that it is normal load of the right ventricle that the pressure of average right ventricle reaches 60mmHg, after exceeding 60mmHg, the ability that the right ventricle further increases the heart and arranges the blood drops seriously, but the one that is worth happying is, if take the positive and effective treatment measure, the heart damaged is taking a favorable turn or reversing.
