Abstract:
Objective To investigate the impact of systolic blood pressure (SBP) at admission on in-hospital outcomes in patients with ST elevated acute myocardial infarction (STEMI).Methods Data of 336 STEMI patients admitted from September 2008 to May 2011 were retrospectively analyzed.Total of 336 STEMI patients were classified into 4 groups as per the level of SBP at admission:group A (＜ 101 mmHg,n =59) ; group B (101-120 mmHg,n =109) ; group C (121-140 mmHg,n =98) and group D (＞ 140 mmHg,n =69).And clinical features,coronary angiography (CAG) findings,the strategy of treatment,complications and hospital mortality were compared among 4 groups with SPSS version 18.0 software.Results The mortality rates of the four groups were 18.64％,1.83％,4.08％,1.45％,respectively.The patients with SBP ＜ 106 mmHg were in greater risk of in-hospital mortality,Killip class ≥ 3 at admission,shock and refractory arrhythmias,and more patients in this group needed pacemaker and intraaortic balloon pump (IABP) treatment than patients in other 3 groups.While there was no significant difference in mortality rate between other three groups.Multivariate logistic regression analysis demonstrated SBP ＜ 101 mmHg (OR =6.368,P =0.002) and peak value of troponin Ⅰ (OR =3.781,P =0.008) were independent risk factors of in-hospital death in STEMI patients.Conclusions The STEMI patients with SBP ＜ 101 mmHg at admission had higher mortality rate and low SBP at admission had great prognostic value in short-term outcomes of STEMI.
