Randomized Controlled Trial Multicenter Study Clinical Trial
Myocardial perfusion imaging for evaluation and triage of patients with suspected acute cardiac ischemia: a randomized controlled trial.
Observational studies of acute myocardial perfusion imaging in emergency department (ED) patients with chest pain have suggested high sensitivity and negative predictive value for acute cardiac ischemia, but use of this method has not been prospectively tested. ⋯ Sestamibi perfusion imaging improves ED triage decision making for patients with symptoms suggestive of acute cardiac ischemia without obvious abnormalities on initial ECG. In this study, unnecessary hospitalizations were reduced among patients without acute ischemia, without reducing appropriate admission for patients with acute ischemia.

The technology and expertise of critical care practice support patients through life-threatening illnesses. Most recover; some die quickly; others, however, linger--neither improving nor acutely dying, alive but with a dwindling capacity to recover from their injury or illness. Management of these patients is often dominated by the question: Is it appropriate to continue life-sustaining therapy? Patients rarely participate in these pivotal discussions because they are either too sick or too heavily sedated. ⋯ However, the potential for strained communications is mitigated if clinicians provide timely clinical and prognostic information and support the patient and family with aggressive symptom control, a comfortable setting, and continuous psychosocial support. Effective communication includes sharing the burden of decision making with family members. This shift from individual responsibility to patient-focused consensus often permits the family to understand, perhaps reluctantly and with great sadness, that intensive caring may involve letting go of life-sustaining interventions.
