Abstract:
Objective To study the relative factors of hypotension after recanalization of infarction related artery(IRA) during emergency PCI for patients with acute myocardial infarction.Methods We retrospectively analyzed the clinical information and the coronary angiograph of 245 consecutive patients with primary acute myocardial infarction undergoing emergency PCI at the first affiliated hospital of China Medical University from January 2003 to September 2006.Twenty seven patients with blood pressure elevated higher than 140/90 mm Hg after reperfusion were excluded.The remaining 218 patients were catagorized into the hypotension group(BP≤90/60 mm Hg,n=102) and the normal blood pressure group(n=116) according to the blood pressure level after reperfusion during emergency PCI.The relative factors of hypotension were analyzed through logistic regression test.Results Compared with the normal blood pressure group,patients in the hypotension group had higher incidences of old age(age ≥60 yrs),heart failure(killip grades≥grade 2),inferior wall or right ventricular infarction,right coronary artery lesions,proximal or total occlusion lesions,multivessal disease and TIMI blood flow≤grade 1 in the IRA after recandization.Mortality rate was also higher in the hypotension group(P1).Conclusion Old age(age ≥60),inferior wall infarction,killip grades≥2,right coronary artery lesions,proximal or total occlusion lesions are the risk factors of hypotension after recanalization of IRA during emergency PCI.The presence of hypotension is correlated with the increase of in hospital mortality.
