If is estimated that>400,000 percutaneous transluminal coronary angioplasty (PTCA) procedures are performed in the Unites states annually.
This study reports patient characteristics and outcomes for 163,527 PICAs performed in 214 hospitals in 17 states from 1993 to 1994.
These hospitals were a 20% random sample of hospitals in the Healthcare Cost and Utilization Project, which was designed to reflect hospitalization in the United states, generally.
Cases with International classification of Diseases, 9th Revision, Clinical Modification procedure codes 36.01,36.02, and 36.05 were defined as PTCA and were categorized as to whether acute myocardial infarction (AMI) was the principal discharge diagnosis.
The average age of 44,270 AMI discharges (27%) was 62 ± 12 years and that of 1 19,257 no-AMI cases (73%) was 64 ± 11 years ; 1/3 of both groups were women, 88% were white, and almost 90% had Medicare or private insurance as the prima payer.
The states contributing the most cases were Florida (26%), California (12%), and Wisconsin (10%). Hospital mortality was 1.7% overall and was 3.8% for AMI and 0.8% for no-AMI cases.
Bypass surgery performed during the same admission was 3.4% overall and was 4.5% and 3.0% for AMI and no-AMI cases, respectively.
Multivariate analysis showed that advanced age, diabetes, female gender, and Medicaid payer status were associated with increased risk of mortality. (...)
