Use of Pulmonary Artery Catheters in Patients with Acute Myocardial Infarction: Results (3)

The secondary analysis to assess the effect of differences in severity of CHF in patients receiving PAC compared with others revealed that of the patients who were in CHF and received PAC, 15.2 percent were mild, 28.0 percent moderate and 56.8 percent severe, whereas in the patients with CHF who did not receive PAC, 59.5 percent were mild, 21.3 percent moderate and only 19.1 percent were severe. Analysis of in-hospital mortality for 118 patients with CHF (but without persistent hypotension or cardiogenic shock) who received PAC, compared with 246 patients who did not receive PAC, is shown in Figure 3. canadian health&care mall

It can be seen that for patients receiving PAC and classified as mild or moderate CHF, 7.8 percent (four of 51) died. In the similarly classified patients not receiving PAC, 9.4 percent (13 of 139) died. In the 67 patients receiving PAC and classified as severe CHF, 32 (47.8 percent) died. In the 107 patients similarly classified and not receiving PAC, 39 (36.4 percent) died. The mortality ratio was 1.31 (the difference not reaching statistical significance).
