Patients with spontaneous chest pain; safety and prognostic value of early dobutamine stress echocardiography

ABSTRACT

This Study comprised 50 patients with age group of 30-60 years, 40 were female and 10 male patients. All patients underwent serial creatinine phosphokinase enzyme measurements, continuous ECC monitoring for at least 12-24 hours and early Dobutamine Stress Echocardiography [DSE].In patients with negative creatinine kinase enzymes and normal findings of ECG monitoring, [DSE] was considered positive in patients with wall motion abnormalities. Five patients had evidence of early myocardial infarction. In the remaining 45 patients DSE was performed. DSE results were of poor quality in 2, non-diagnostic in 6, negative in 22 and positive in 16 patients. Two patients suffered from tachyarrhythmia, one patient has paroxymal atrial tachycardia [PAT] and other suffered ventricular tachycardia. Both were successfully cardioverted
