Objective To evaluate the feasibility and efficacy of emergency percutaneous coronary intervention( PCI) under mechanical ventilation for the treatment of patients with acute myocardial infarction complicated with acute pulmonary edema. Methods The clinical data of 15 patients admitted to the emergency ward for acute pulmonary edema caused by acute myocardial infarction from 2007 to 2009 were retrospectively analyzed. These patients received emergency PCI under mechanical ventilatory support.Parameters involved changes of symptoms, arterial blood gas, left ventricular ejection fraction( LVEF) , plasma concentrations of B-type natriuretic peptide( BNP) , and high sensitivity reactive protein( hs-CRP) . Results All patients showed significant improvements in dyspnea, artery blood gas parameters after PCI( P lt;0. 01) .LVEF increased significantly after PCI compared with before weaning [ ( 37. 36 ±0. 02) % vs ( 47. 41 ±0. 02) % , F =461. 47, P lt; 0. 05] . The concentrations of BNP and hs-CRP returned to lower level 4 weeks after PCI [ ( 99. 34 ±5. 15) fmol /mL vs ( 430. 50 ±96. 08) fmol /mL, ( 8. 35 ±2. 49) ng/mL vs ( 89. 50 ±9. 30) ng/mL, both P lt;0. 01] . Conclusion Emergency PCI under mechanical ventilatory support is a feasible and effective approach for patients with acute myocardial infarction complicated with acute pulmonary edema.
