The features of the coronary angiography and nursing for elderly patients with the acute myocardial infarction

Objective:To investigate the features of the coronary angiography(CAG) results and the complications in periangiography period for elderly patients with the acute myocardial infarction(AMI).Methods:CAG were undergone in 564 elderly AMI,who received thrombolytic and anticoagulative therapy within 12 hours from the onset of AMI.The infarction relevant artery(IRA) were classified according to the degree of stenosis with Proudilit classification pricinple.Results:CAG showed that stenosis degree of the artery in 74 cases is less than 15%,that subocclusion and total occlusion in 415 cases,single brunch lesion in 111 cases,double branch lesion in 409 cases,tribrunch lesion in 44 cases and left main trunck lesion in 58 cases.Conclusion:Elder of AMI was multi-branch of coronary artery envolved,with the feature of severe stenosis and blockage.The mechanism is thrombosis formation based on atheromatous plaque.The complications of periangiography was hypotension,contrast reaction and vagal reflects,which disappeared rapidly after properly management.
