Aggressive testing provides no benefit to patients in ER with chest pain

Patients who go to the ER with chest pain often receive unnecessary tests to evaluate whether they are having a heart attack, a practice that provides no clinical benefit and adds hundreds of dollars in health-care costs, according to new research. CT scans and cardiac stress tests are overused in the ER for patients with chest pain and provide no information to determine whether a patient is in the midst of a heart attack.
