Relation of early and one-year outcome after acute myocardial infarction to systemic arterial blood pressure on admission.
We evaluated whether elevated blood pressure (BP) levels with an acute myocardial infarction (AMI) affect the in-hospital course, short-term, and 1-year outcome. Data were derived from a nationwide survey of 2,212 consecutive patients with AMI. Patients were stratified into 3 groups according to admission BP levels: 1,320 patients had normal BP, 840 patients had high BP, and 52 patients had excessive BP. In-hospital (7 days) course, short-term (30 days), and 1-year outcome was compared between the groups. The 3 groups were similar with respect to age, but patients with excessive BP were more likely to be women and have a history of systemic hypertension and diabetes mellitus. The rate of thrombolytic therapy was similar among the 3 groups, but patients with excessively elevated BP were treated during hospitalization much more often with beta blockers, angiotensin-converting enzyme inhibitors, and diuretics. The incidence of stroke, transient ischemic attack, and bleeding complications were comparable in the 3 groups. In-hospital mortality was 5.0% , 4.0%, and 1.9% in the normal, high, and excessively elevated BP groups, respectively (p = 0.19). The short-term rehospitalization or mortality rate was similar among the 3 groups. The 1-year mortality rate was 12.3%, 14.1%, and 10.2% in the normal, high, and excessively elevated BP groups, respectively (p = 0.61). A multivariate logistic regression analysis yielded age, women, and Killip class > or = 2 as the only significant predictors of mortality during follow-up. Thus, with the current medical therapy, excessively elevated BP levels with AMI is not associated with a worse short-term or 1-year outcome.
