The Impact of Myocardial Infarction vs. Pneumonia on Outcome in Acute Ischemic Stroke.

Academic Article

Abstract

  • The aim of this study was to examine the association between MI and PNA in the setting of acute ischemic stroke and patient outcome. Eligible patients were identified from a prospectively collected stroke registry and included if transthoracic echocardiography (TTE) was performed during their inpatient stay. 426 patients met inclusion criteria (mean age 64, 73% Black, 48% female). Twenty-one patients (4.9%) experienced an MI. Patients who later suffered a MI initially presented with more severe strokes (median NIHSS 7 vs. 5, p=0.014). More patients in the MI group experienced pneumonia (26% vs. 9%, p=0.004). After adjusting for age, baseline glucose and NIHSS, the odds of in-hospital mortality for patients with MI was 3 times that of those without MI (OR 3.2 95% CI 1.1-9.7, p=0.036). When adjustment was made for pneumonia, age, baseline glucose and NIHSS, MI was no longer significantly related to in-hospital mortality (OR 2.5 95% CI 0.8-8.2, p=0.131). In our sample, while MI was significantly associated with in-hospital mortality, this association was attenuated after adjusting for presence of pneumonia. Our findings raise the question as to whether the prevention of pneumonia could improve in-hospital mortality among patients who experience MI in the setting of ischemic stroke.
