Insights
Transesophageal atrial pacing stress echocardiography (TAPSE) effectively predicts cardiac death in patients with coronary artery disease. An abnormal TAPSE result significantly increases the risk, showing its long-term prognostic value.
Area of Science:
- Cardiology
- Diagnostic Imaging
- Clinical Prediction
Background:
- Pharmacologic stress echocardiography is established for cardiac death prediction.
- Transesophageal atrial pacing stress echocardiography (TAPSE) offers a safe alternative.
- Prognostic data for TAPSE was previously unavailable.
Purpose of the Study:
- To evaluate the long-term predictive value of TAPSE for mortality.
- To assess TAPSE's utility in patients with known or suspected coronary artery disease.
Main Methods:
- 1010 TAPSE procedures were performed in 975 patients.
- A final cohort of 857 patients with a mean follow-up of 4.5 years was analyzed.
- Cox regression models identified predictors of cardiac death.
Main Results:
- Abnormal TAPSE was observed in 32% of patients, correlating with higher cardiac mortality (8.9% vs 3.6%).
- Predictors of cardiac death included age, prior revascularization, and resting/induced wall motion abnormalities.
- Abnormal TAPSE significantly improved cardiac death prediction models.
Conclusions:
- TAPSE is a valuable tool for predicting mortality in coronary artery disease patients.
- TAPSE can serve as an alternative to pharmacologic stress testing for risk stratification.
Objectives:
It was the aim of this study to investigate the long-term value of transesophageal atrial pacing in predicting death in patients with known or suspected coronary artery disease.
Background:
Exercise, dobutamine and dipyridamole stress echocardiography are all effective in predicting cardiac death. Transesophageal atrial pacing stress echocardiography (TAPSE) is a safe alternative to pharmacologic tests, but no information is available on prognosis with TAPSE.
Methods:
One thousand and ten TAPSE were performed in 975 consecutive patients. TAPSE was feasible in 970 tests (96%); after exclusion of the 35 patients with more than 1 TAPSE and those 42 lost at follow-up (mean 4.5 +/- 3.7 years, median 6 years), the final population consisted of 857 patients (675 males, 58 +/- 9 years old). The Cox model was used to analyze the association of clinical, resting and TAPSE variables with cardiac death.
Results:
TAPSE was abnormal in 281 (32%) patients. There were 46 cardiac-related deaths (5%), 25 among the 281 patients with an abnormal test (8.9%) and 21 among the 576 patients with a normal test (3.6%). The predictors of cardiac death were age, previous revascularization, resting wall motion score index and its variation during TAPSE. Abnormal TAPSE significantly increases the value of models predicting cardiac death. Moreover, cardiac mortality increased progressively with the extent of the induced ischemia.
Conclusions:
TAPSE is a useful tool in predicting death in patients with known or suspected coronary artery disease and might be considered an alternative to pharmacologic stressors.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
