Age-related Changes in the Left Ventricular Twist

Öz:
Giriş: Sol ventrikül (LV) rotasyon ve büküm hareketi kasılma ve gevşemede önemli rol oynamaktadır. Yaşlanma ile LV sistolik fonksiyonları korunsada diyastolik fonksiyonlar genellikle bozulur. Bu çalışmanın amacı, LV büküm için bir referans değeri saptamak ve yaşlanmanın büküm üzerinde etkilerini incelemekti.Hastalar ve Yöntem: Çalışmaya 75 sağlıklı kişi dahil edildi; katılımcılar 40 yaş üstü ve 40 yaş altı olarakiki gruba ayrıldı. LV rotasyon ve büküm parasternal kısa eksen bazal ve apikal seviyelerinde 2D-STI iledeğerlendirildi. LV büküm hareketi apikal ve bazal rotasyonun göreceli toplamı olarak tanımlandı. İskemik vekapak hastalığı, aritmi, kalp pili ve sistolik disfonksiyon öyküsü dışlama kriterleri olarak tanımlandı.Bulgular: Yaşlılarda gençlere kıyasla pik A dalga hızı (70.6 ± 13.7 vs. 57.7 ± 10.6, p< 0.001), E/E' oranı(7.7 ± 2.23 vs. 6.09 ± 1.3, p< 0.001) daha yüksek, pik E dalga hızı (52.4 ± 16 vs. 76.75 ± 11, p< 0.001), E/Aoranı (0.75 vs. 1.34, p< 0.001) daha düşüktü. Yaşlı grupta apikal rotasyonda artış (4.4 ± 2.9° vs. 3.3 ± 2.4°, p=0.075) ve bazal rotasyonda azalma (-4.1 ± 2.7° vs. 3.7°± -5.2, p= 0.185) izlendi ancak, bu değişiklikler anlamlıdeğildi. Yaşlanma ile birlikte, büküm önemsiz derecede arttı (8.6 ± 3.3° vs. 8.53 ± 4.1°, p= 0.890). Yaşlı gruptaLV diyastolik disfonksiyon derecesi arttıkça apikal rotasyon (5.02 ± 3.2 vs. 2.4 ± 1.1, p= 0.004) ve büküm (9.4± 3.4 vs. 6.9 ± 2.4, p= 0.64) azaldı.Sonuç: Bu çalışma LV bükümün yaşla birlikte hafifçe arttığını, ancak bu etkinin sistolik fonksiyonları normalolsada artmış diyastolik disfonksiyon varlığında tersine döndüğünü gösterdi.

Sol Ventrikül Bükülme Hareketinde Yaşa Bağlı Değişiklikler

Introduction: Left ventricular (LV) rotation and twist play important roles in LV contraction and relaxation. Systolic function is usually preserved with aging, but diastolic function deteriorates. The aim of this study was to establish a reference value for LV twist and examine the effect of aging on it Patients and Methods: We enrolled 75 healthy subjects who were divided into two groups according to age:< 40 and > 40 years. LV rotation and twist were assessed with two-dimensional speckle tracking imaging atthe basal and apical levels of the parasternal short axis. LV twist was defined as an apical rotation relativeto the baseline. Exclusion criteria included a history of ischemic and valvular disease, arrhythmia, use of apacemaker, and systolic dysfunction.Results: Peak A wave velocity (70.6 ± 13.7 vs. 57.7 ± 10.6, p< 0.001) and E/E’ratio (7.7 ± 2.2 vs. 6.1 ± 1.3,p< 0.001) were higher and peak E wave velocity (52.4 ± 16 vs. 76.8 ± 11, p< 0.001) and E/A ratio (0.75 vs.1.34, p< 0.001) were lower in old patients than in young patients. There was an increase in apical rotation (4.4± 2.9° vs. 3.3 ± 2.4°, p= 0.075) and a decrease in basal rotation (−4.1 ± 2.7° vs. −5.2 ± 3.7°, p= 0.185) in oldpatients, but these changes indicated no significant difference. With aging, the twist increased (8.6 ± 3.3° vs.8.5 ± 4.1°, p= 0.890), but not significantly. LV apical rotation (5 ± 3.2 vs. 2.4 ± 1.1, p= 0.004) and twist (9.4± 3.4 vs. 6.9 ± 2.4, p= 0.64) decreased in the old group with an increasing degree of LV diastolic dysfunction.Conclusion: LV twist slightly increased with age, but this effect was reversed with increased diastolicdysfunction even in the presence of normal systolic function.
