Title

The value of negative stress echocardiography in predicting cardiovascular events among adults with no known coronary disease

Pages

  85-94

Abstract

 Introduction: Stress Echocardiography is a safe and cost-effective method of evaluating the patients with suspected coronary artery disease (CAD). However, the risk factors of an adverse cardiovascular event after a normal exercise (ESE) or dobutamine (DSE) Stress Echocardiography are not well established. Methods: A cohort of 705 patients without previous history of CAD and a negative ESE/DSE was studied. All studies were performed in a high-volume echocardiologic laboratory and interpreted by two experienced echocardiography-trained cardiologists. Patients with inconclusive studies and those with an evidence of myocardial ischemia were excluded. Demographic, echocardiographic and hemodynamic findings were recorded. Patients were followed for at least 2 years. Independent predictors of major adverse cardiovascular events (MACE) were determined by regression analysis. Results: During a period of 55. 7± 17. 5 months, MACE occurred in 35 (5. 0%) of patients. Negative predictive value (NPV) of DSE was 89. 2%, which was significantly less than 96. 5% for ESE in predicting the occurrence of MACE (P = 0. 001). MACE occurred more frequently among older (≥ 65 years) men with preexisting diabetes, hypertension, and/or hyperlipidemia. During ESE, a higher maximum blood pressure*heart rate product for the achieved level of metabolic equivalent (METS) of tasks was also an independent predictor of MACE. Conclusion: Inability of patients to undergo traditional ESE that led to the choice of using DSE alternative reduces the NPV of the Stress Echocardiography among patients without previous history of CAD. A modest rise of heart rate and blood pressure in response to increased level of activity serves as favorable prognostic value and improves the NPV of Stress Echocardiography.
