Clinical and demographic differences between patients with positive and negative troponin who were attended with supraventricular tachycardia and chest pain at emergency departments
Abstract
Introduction: The presentation of supraventricular tachycardia (SVT) with chest pain and elevation of biomarkers contributes to the diagnosis of acute myocardial infarction in the patients who have them.
Objective: To evaluate the clinical and sociodemographic characteristics of patients with SVT and chest pain; as well as to know the prevalence of cardiovascular risk factors, electrocardiographic findings, troponin measurement results and the correlation of these variables with the results of ischemia detection tests and coronary angiography.
Method: There were reviewed the admissions to emergency departments of patients with SVT, chest pain, and high sensitivity troponin I measurement who underwent ischemia detection test or coronary angiography.
Results: A total of 199 patients with an average age of 68 years were included. The 53.3% (106/199) were women, 70.6% (141/199) had some cardiovascular risk factor and high blood pressure was more prevalent 53.8% (107/199). The 38.2% (76/199) of patients had positive troponins and showed statistically significant differences with respect to a higher heart rate (145.5 vs. 133.5 lpm, p<0.05) and a history of coronary disease (26.3% [20/76] vs. 9.8% [12/123], p<0.05). Men predominated (79.3% vs. 20.7%, p<0.01), with a history of coronary disease (41.4% [12/29] vs. 11.8% [20/170]; <0.01) and with positive troponins (79.3% [23/29] vs. 31.2% [53/170], p<0.01).
Conclusions: More than a third of patients with SVT and chest pain showed elevated troponins, which was related to the finding of coronary disease. The male sex and previous coronary disease were more frequently associated with significant coronary artery disease.
