“…The Tei index derived from pulsed Doppler echocardiography is calculated as follows: (IVCTϩIVRT)/ET, where IVCT is isovolumic contraction time, IVRT is isovolumic relaxation time, and ET is ejection time. 33,34 In patients with acute PE, the most significant echocardiographic finding, when compared with patients with chronic pulmonary hypertension, is marked prolongation of IVCT and IVRT over the tricuspid annulus resulting in a higher right index of myocardial performance (RIMP) in the acute PE group. Because of acute events, the adaptation of the LV is not completely achieved.…”

Echocardiography can be used for rapid and accurate risk stratification of patients with pulmonary embolism to appropriately direct the therapeutic strategies for those at high risk. Echocardiography is an ideal risk stratification tool in this regard because of its easy portability to the emergency room or to the bed side. It can be performed at a relatively low cost and at no risk to the patient. Furthermore, echocardiography allows repetitive noninvasive assessment of the cardiovascular and hemodynamic status of the patient and the response to the therapeutic interventions. Right ventricular hypokinesis, persistent pulmonary hypertension, a patent foramen ovale, and a free floating right heart thrombus are echocardiographic markers that identify patients at a higher risk for morbidity and mortality. Such patients warrant special consideration for thrombolysis or embolectomy.

“…Therefore, Tei index may be a more objective parameter in the assessment of RV function in acute PE. Also, other investigators found the RV Tei index was easy to measure and to be reproducible (9,13).…”

“…However, there is a limited data in the literature about evaluation of the RV function by Tei index in patients with acute PE. Impaired RV Tei index has been improved with effective treatment in two previous studies (9,13). RV Tei index is an important factor to predict outcomes in patients with acute PE.…”

Objective: The role of increased troponin level in risk stratification of acute pulmonary embolism (PE) is well documented. However, relation between right ventricular (RV) myocardial performance (Tei) index and cardiac troponin-T (cTn-T) has not been well investigated. The purpose of this observational prospective study was to assess the relationship between the RV Tei index and cTn-T in patients with acute normotensive PE. Methods: Thirty-eight patients with acute PE diagnosed by computed spiral tomography pulmonary angiography were enrolled to this prospective observational study. All study population underwent a comprehensive echocardiographic study including tissue Doppler imaging within first 12 hours of admission. cTn-T levels were measured on admission. Follow-up echocardiography was performed routinely at the 7 th day of hospitalization. Echocardiographic evaluation was repeated at 90 days in patients with insufficient improvement of RV Tei index. The difference between the baseline and follow-up data was analyzed using the paired sample t-test or Wilcoxon test according to normality of distribution. Results: The mean of the RV Tei index was 0.46±0.14 and the mean systolic pulmonary artery pressure (sPAP) was 40±20 mmHg. Increased cTn-T level was detected in 37% of the patients (normal value 0.01< ng/mL). Significant correlations were observed between RV Tei index and sPAP with cTn-T levels (r=0.467 and r=0.468, p<0.001, respectively). In logistic regression analysis, RV Tei index was associated with positive cTn-T values (OR-136, 95% CI: 1.3-14657, p=0.039). After the anticoagulant treatment, RV Tei index and sPAP were significantly improved. Conclusion: RV Tei index is frequently impaired in patients with acute PE and a significant recovery is seen after the treatment. Therefore, RV Tei index may be used both the diagnosis of RV dysfunction and the assessment of treatment effectiveness. RV Tei index is may predict myocardial injury in PE. Yöntemler: Prospektif gözlemsel bu çalışmaya, bilgisayarlı spiral tomografik pulmoner anjiyografi ile tanısı konulan 38 PE hastası dahil edildi. Tüm çalışma popülâsyonuna, hastaneye kabulün ilk 12 saati içinde, doku Doppler görüntülemeyi içeren kapsamlı bir ekokardiyografik inceleme yapıldı. cTn-T seviyesi hastaneye kabulde ölçüldü. Hastanedeki tedavinin yedinci gününde rutin olarak takip ekokardiyografisi yapıldı. SV Tei indeksinde düzelme olmayan hastaların ekokardiyografisi doksanıncı günde tekrarlandı. Başlangıç ve takip değerleri dağılıma uygun olarak bağımsız örneklem t-testi veya Wilcoxon test ile değerlendirildi. Bulgular: Ortalama SV Tei indeksi 0.46±0.14 ve ortalama sistolik pulmoner arter basıncı (sPAP) 40±20 mmHg idi. Hastaların %37'sinde artmış cTn-T düzeyi saptandı (normal değer 0.01< ng/mL). SV Tei indeksi, sPAP ve cTn-T düzeyi arasında anlamlı korelasyon gözlendi (r=0.467 ve r=0.468, p<0.001,
