| Popis: | Background: Published experience with coronary angioplasty in patients with severely depressed left ventricular (LV) ejection fraction indicates that procedural complications are more frequent in such patients than in those with normal or near normal LV function. Although the immediate outcomes of transcatheter revascularization in unselected populations have improved substantially since the procedures upon which these reports were based were performed, outcomes with this subset of patients has not been recently reviewed. Hypothesis: This study was undertaken to document the results of the application of current transcatheter technology to this patient subset. Methods: We analyzed data from 194 consecutive patients with a visually estimated LV ejection fraction < 30%, who underwent coronary angioplasty in this institution between January 1, 1995, and April 30, 1996, and compared their outcomes with those of 1,390 patients with normal LV function treated concurrently. Results: Angiographic success in the two groups was similar. The hospital mortality of the patients with low ejection fraction was higher (2.6 vs. 0.6%, p=0.02) than in concurrently treated patients with normal LV function. Other procedural complications were no more frequent than in such patients. Late mortality in patients with low ejection fraction was 16%, a similar value to that in older reports. Conclusion: Compared with older reports, current hospital outcomes of coronary angioplasty are improved in patients with severely depressed LV function. Unfortunately, late outcomes are not demonstrably better. |
