Neurocardiology is an emerging specialty that addresses the interaction between the brain and the heart, i.e. the effects of cardiac injury on the brain, and the effects of brain injury on the heart. Accumulating clinical and experimental evidence suggests a causal relationship between brain damage and heart dysfunction.

Inclusion criteria

1. Adult patients aged ≥ 18 years.
2. Acute supratentorial or carotid stroke. Exclusion criteria

1. Invasive arterial signal unsuitable to obtain hemodynamic data. 2. Emergency neurosurgery needed before intra-arterial treatment. 3. Once enrolled, the patient can be excluded from the study because of one of the following intraoperative conditions:

1. Intraoperative technical limitations limiting or impeding the arterial re-opening
2. Persistent low quality of the arterial signal. After positioning the patient and zeroing the arterial signal, the arterial waveform is checked for quality by means of a square-wave test and optimized in the case of the occurrence of under or over-damping.
