Temporal Trends and Factors Associated With Pulmonary Artery Catheterization in Patients With Acute Myocardial Infarction: Conclusion

As an illustrative example, the coronary care unit was introduced in the mid-1960s with the expectation that these specialized care units would reduce hospital mortality associated with AMI in part by rapidly detecting and treating ventricular fibrillation. Acceptance of this approach to the management of AMI by clinicians was relatively slow at first followed by rapid acceptance and widespread utilization of such units. However, following the publication of two randomized trials in Great Britainthat failed…

Temporal Trends and Factors Associated With Pulmonary Artery Catheterization in Patients With Acute Myocardial Infarction: Discussion

Of the various diagnostic procedures used in patients with AMI, PA catheterization is widely recommended to be of diagnostic and therapeutic benefit” and, therefore, is frequently utilized. However, the practice of PA catheterization has come under scrutiny and criticism as being commonly performed without adequate assessment of its appropriate utilization and benefit A Few studies have examined the demographic and clinical characteristics of patients with AMI undergoing PA catheterization, particularly so from a community-wide perspective;…

Temporal Trends and Factors Associated With Pulmonary Artery Catheterization in Patients With Acute Myocardial Infarction: Results

Temporal Trends in PA Catheter Utilization Use of the PA catheter in all patients with AMI studied increased from 1975 to 1984 with a consistent decline thereafter (Fig 1). In the 2,441 patients with complicated AMI in whom utilization rates of the PA catheter were between approximately one and one half to two times greater than in all patients with AMI studied, use of PA catheterization progressively increased from 1975 through 1988 with a decline…

Temporal Trends and Factors Associated With Pulmonary Artery Catheterization in Patients With Acute Myocardial Infarction: Data Analysis

The medical records of all patients with a primary or secondary hospital discharge diagnosis of AMI (Ninth International Classification of Disease Codes 410 and 411) from participating hospitals were individually reviewed and validated according to predefined diagnostic criteria that have been described previously. In brief, these criteria included satisfaction of at least two of the following three factors: clinical history, serum enzyme level elevations, and serial electrocardiographic findings. The occurrence of selected complications during hospitalization…

Temporal Trends and Factors Associated With Pulmonary Artery Catheterization in Patients With Acute Myocardial Infarction

The care of patients with acute myocardial infarction (AMI) has undergone significant change over the past several decades, in part due to the introduction and use of bedside hemodynamic monitoring. The flow-directed pulmonary artery (PA) catheter was introduced by Swan and associates in 1970 and has been widely used in scores of critically ill patients since that time. It has been estimated that approximately 100,000 patients with AMI undergo PA catheterization annually in the United…
