Cardiocerebral Infarction: A Single Institutional Series

Abstract

ObjectivesCardiocerebral infarction (CCI) is the rare occurrence of acute ischemic stroke (AIS) and acute myocardial infarction (AMI), either at the same time (simultaneous or synchronous) or one after the other (metachronous). The aim of this study is to describe the clinical profile, management and treatment outcomes of patients with CCI. Materials and methodsThis is a 3-year cross-sectional study of patients with CCI describing their clinical presentation, management, and outcomes. The primary outcome measures were all-cause mortality and functional outcome measured with the modified Rankin Scale score (mRS) at discharge and at 30 days post-CCI. We also described the frequency of major and minor hemorrhagic events. ResultsOut of 1683 AIS patients and 1983 AMI patients admitted during our time period, 29 patients fulfilled the inclusion criteria (mean age 60 ±12, 79% males, median admission NIHSS 16 [range 1–26]). Of these, 20 (69%) had metachronous CCI while 9 (31%) had synchronous CCI. Most of the patients were given antithrombotics and only 14% were given reperfusion therapies. The all-cause mortality is 45% and 69% of which were cardiovascular deaths. Seventeen and 21% of CCI patients had a good functional outcome on discharge and at 30 days from CCI onset respectively. A total of 8 (28%) patients had hemorrhagic events. ConclusionsWe present the largest single institutional series showing the prevalence rate of cardiocerebral infarction to be 0.79% (0.55% for metachronous, 0.25% for synchronous), with patients presenting as moderate-severe acute ischemic strokes and high-risk acute myocardial infarction. These patients have a high mortality rate with a significant proportion having cardiovascular deaths.
