當血壓長期處於過高狀態的時候，便有機會出現心臟肥大(Cardiac hypertrophy)的情況。440Please respect copyright.ＰＥＮＡＮＡX67zEfNabm

(圖2)心臟的肌肉會利用收縮及膨脹的舉動把血液送到全身，如果血壓高企的話，心臟肌肉細胞便會自行膨脹增大，好使心臟有更強力量抵禦血液帶來的壓力，且能繼續維持正常功能把血液送往全身。440Please respect copyright.ＰＥＮＡＮＡZBheDMpM7S

這現象稱之為心臟肥大(Cardiac hypertrophy)。440Please respect copyright.ＰＥＮＡＮＡWCqb3SDFWB

(圖3)當血壓持續高企及攀升到某一個位，心臟的肌肉再也沒法透過膨脹增大來維持運作，這時候心臟便會進入「放棄人生」的狀態，再也不會激烈地膨脹收縮，形成心臟衰竭(Heart failure)局面，血液因而再也沒能輸送到身體各部位。440Please respect copyright.ＰＥＮＡＮＡNjfOWaX2oq

換句話說，長期因高血壓所造成的心臟肥大(Cardiac hypertrophy)，會是形成心臟衰竭(Heart failure)的其中一道誘因。440Please respect copyright.ＰＥＮＡＮＡcmEuVc5vVe

(圖4)有見及此，有不少科學家會以人工方式在動物模型上製造心臟肥大(Cardiac hypertrophy)的局面，藉此了解箇中對細胞所做成的影響，從而找出防止下一步心臟衰竭(Heart failure)的潛在發生。440Please respect copyright.ＰＥＮＡＮＡheKUhrJgCv

其中的一種手段，就是利用縫線的手法局部減低心臟血管血液流動的動向。440Please respect copyright.ＰＥＮＡＮＡhHy9ZPnVAz
從圖中可見，縫線後左心房所承受的血壓將會大幅度增強。440Please respect copyright.ＰＥＮＡＮＡmgwCp8P2Cu

(圖5)圖中可以清晰見得到，縫線後左心房的確出現肥大的狀況。440Please respect copyright.ＰＥＮＡＮＡxx7B0ztquO
