Background
The incidence and outcomes of early cardiac complications in patients with intracerebral hemorrhage (ICH) are poorly understood. These cardiac complications may be part of the so-called stroke-heart syndrome in patients with ICH. We investigated this issue in an individual patient data pooled analysis from an international repository of clinical trial data.

Methods
We used the Virtual International Stroke Trials Archive to investigate the incidence of cardiac complications within 30 days post-ICH or acute ischemic stroke (AIS). These complications included acute coronary syndrome encompassing myocardial injury, heart failure/left ventricular dysfunction, atrial fibrillation/atrial flutter, other arrhythmia/ECG abnormalities, and cardiorespiratory arrest. We used propensity score matching to compare the incidence of patients with stroke-heart syndrome in patients with ICH with those following AIS. Factors associated with 90-day mortality were evaluated using multivariate logistic regression analysis in the ICH cohort.

Results
We pooled data from 8698 participants recruited in acute stroke trials (mean age, 68±12 years; 56% male), of whom 914 (11%) were patients with ICH. Among the patients with ICH, 123 (13%) had stroke-heart syndrome in patients with ICH. Following propensity score matching, a total of 1828 patients (914 for each of the cohorts) were analyzed. While the overall incidence of cardiac events tended to be lower in the ICH group compared with the AIS group (the cumulative incidence freedom from the event, 86.3% [95% CI, 84.1–88.6] versus 83.6% [95% CI, 81.2–86.0]; P=0.100), the incidences cardiac events other than atrial fibrillation/atrial flutter were comparable between the 2 matched groups. The incidence of atrial fibrillation/atrial flutter was significantly lower in the ICH group than in the AIS group (P<0.001). The multivariate-adjusted analysis found that stroke-heart syndrome in patients with ICH was associated with 90-day mortality (adjusted odds ratio, 1.12 [95% CI, 1.06–1.19]; P<0.001).

Conclusions
Cardiac events are common and negatively affect prognosis in patients with ICH, just as seen in AIS.
