Critical pathways in cardiology

Management of acute myocardial infarction with ST elevation (STEMI) remains a challenge for academic institutions. There are numerous factors at play from the time electrocardiogram is obtained to the time the patient arrives to a catheterization laboratory and the balloon is inflated. Academic hospitals that are located in large urban centers have to deal with staff living long distances from the facility, and therefore, assembling the catheterization team after-hours and on the weekends becomes a difficult task to achieve. ⋯ Therefore, it is imperative that institutions do all they can to improve their protocols and meet the core measures in the treatment of STEMI patients, including the door-to-balloon time of less than 90 minutes. Our institution started a quality improvement program for STEMI care in 1993 and has showed progressive improvement in use of aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, and other medication, culminating in 95% to 100% use of these medications in 2003-2004, when we operated in accordance with the Get With The Guidelines program. Door-to-balloon time in less than 90 minutes became a new phase in our quality improvement process, and we achieved 100% compliance in the last 2 years.

Comparative Study
Cost-effectiveness of a novel indication of computed tomography of the coronary arteries.
A common strategy for excluding coronary artery disease among patients presenting with low-risk chest pain is observation unit (OU) admission with serial cardiac biomarkers and stress testing for cardiac risk stratification. Patients with positive- or indeterminate-stress tests are often admitted for cardiac catheterization despite a low likelihood of disease. The aim of this study is to estimate the cost-effectiveness of computed tomography of the coronary arteries (CTCA) in the OU for the evaluation of low-risk chest pain patients with indeterminate- or positive-stress test results. ⋯ In this computer-modeled analysis, the addition of CTCA following positive- or indeterminate-stress tests to an OU cardiac risk-stratification pathway for low-risk chest pain patients achieved significant cost savings with a small decrease in life expectancy per patient. Adding CTCA after indeterminate- or positive-stress test results is a cost-effective intervention for further risk-stratifying low-risk chest pain patients in the OU setting before proceeding to traditional coronary angiography.

Chest pain unit (CPU) observation with defined stress utilization protocols is a common management option for low-risk emergency department patients. We sought to evaluate the safety of a joint emergency medicine and cardiology staffed CPU. ⋯ Joint emergency medicine and cardiology management of patients within a CPU protocol is safe, efficacious, and may safely reduce stress testing rates.

Emergency department observation units (EDOUs) serve an important role in the evaluation and risk stratification of low-risk chest pain patients. ⋯ In conclusion, intermediate-risk chest pain patients in an EDOU had higher rates of significant cardiac events and inpatient admission. Intermediate-risk patients may be appropriate for EDOU placement, given the acceptable inpatient admission rate and the lack of significant adverse events in the 30-day follow-up period. However, given the higher rate of significant cardiac events, the results of our study emphasize the need for increased vigilance and close cardiology consultation in the intermediate-risk group.
