Abstract

Data regarding the relationship between systolic blood pressure (SBP) at admission and in-hospital outcome in patients with acute myocardial infarction (AMI) undergoing primary percutaneous coronary intervention (PCI) are still lacking in Japan. A total of 1475 primary PCI-treated AMI patients were classified into quintiles based on admission SBP (<105 mmHg, n=300; 105-125 mmHg, n=294; 126-140 mmHg, n=306; 141-158 mmHg, n=286; and ≥159 mmHg n=289). The patients with SBP<105 mmHg tended to have higher age, previous myocardial infarction, chronic kidney disease (CKD), Killip class≥3 at admission, right coronary artery, left main trunk (LMT), or multivessels as culprit lesions, larger number of diseased vessels, lower Thrombolysis In Myocardial Infarction (TIMI) grade in the infarct-related artery before primary PCI, and higher value of peak creatine phosphokinase concentration. Patients with SBP<105 mmHg had a significantly higher mortality, while mortality was not significantly different among the other quintiles: 24.3% (<105 mmHg), 4.8% (105-125 mmHg), 4.9% (126-140 mmHg), 2.8% (141-158 mmHg), and 5.2% (≥159 mmHg) (p<0.001). On multivariate analysis, Killip class≥3 at admission, LMT or multivessels as culprit lesions, admission...Continue Reading
