Abstract Objective. To determine the frequency of a precipitating event occurring prior to the onset of fibromyalgia syndrome, in a consecutive series of patients. Outcome in patients in whom there was a causative factor was compared with that in patients with primary fibromyalgia. Methods. Records of patients presenting over a 4‐year period who fulfilled criteria for fibromyalgia were reviewed, and patients were classified as having reactive fibromyalgia if a specific event prior to the onset of illness could be identified. Outcome features, including employment status and disability compensation, were compared in patients with reactive fibromyalgia versus those with primary fibromyalgia. Results. Twenty‐nine of 127 patients (23%) with a primary rheumatologic diagnosis of fibromyalgia reported having trauma, surgery, or a medical illness before the onset of fibromyalgia, and were classified as having reactive fibromyalgia. Patients in this group were more disabled than those with primary fibromyalgia, resulting in loss of employment in 70%, disability compensation in 34%, and reduced physical activity in 45% Conclusion. The development of fibromyalgia after a precipitating event may represent the onset of a prolonged and disabling pain syndrome with considerable social and economic implications.
The diagnostic accuracy of dobutamine stress echocardiography is limited in patients with poor transthoracic acoustic windows. Transesophageal echocardiography (TEE) overcomes these limitations and thus may increase the clinical usefulness of dobutamine stress echocardiography. The present study was designed to compare the diagnostic accuracies of transesophageal and transthoracic dobutamine stress echocardiography for the identification of coronary artery disease (CAD) in a cohort of patients with a higher incidence of poor acoustic windows. Forty‐two male patients (mean age, 66 ± 9 years) underwent dobutamine stress echocardiography with simultaneous transesophageal and transthoracic imaging. Coronary arteriography was performed in 28 patients (67%). Transesophageal imaging adequately visualized 99.6% of left ventricular segments compared with 76.2% visualized by transthoracic imaging ( P < 0.0001). There was substantial agreement between the two techniques for segmental wall motion analysis at baseline (kappa 0.76; 95% CI, 0.70–0.82); however, at peak dobutamine dose, agreement was significantly reduced (kappa 0.62; 95% CI, 0.55–0.69). The sensitivity (88% vs 75%), specificity (100% vs 75%), and positive predictive value (100% vs 80%) for the identification of CAD were all superior for transesophageal imaging. Transesophageal imaging correctly identified 11 of the 12 patients (92%) with multivessel disease compared with 5 patients (42%) identified by transthoracic imaging ( P < 0.03). There were no major complications. Transesophageal dobutamine stress echocardiography is a safe, feasible, and accurate technique for the identification and risk stratification of patients with CAD. Transesophageal imaging appears to be superior to transthoracic imaging for identifying both the presence and extent of CAD, specifically in patients with poor acoustic windows.
