Heart-brain interactions

Abstract

Heart-brain interactions are represented by the association of cerebral ischemia with coronary artery disease, cardioembolic cerebral ischemia, and cardiovascular complications due to brain damage. As atherosclerosis is a systemic inflammatory disease, in patients with transient ischemic attack, stroke or asymptomatic carotid artery disease, a previous myocardial infarction, angina or an asymptomatic coronary artery disease are often associated and a correlation between the carotid atherosclerosis and coronary artery disease severity has been reported. Furthermore, the long-term prognosis of patients with stroke is strongly affected by coronary events. At the same time, the prevalence of concomitant cerebrovascular disease is common in patients with coronary artery disease. Other cardiovascular diseases, including left atrial and left atrial appendage thrombosis in atrial fibrillation, thrombi in the left ventricle in acute and chronic coronary artery disease and dilated cardiomyopathies, infective endocarditis with vegetations, cardiac valve prosthesis thrombosis, cardiac tumors, mitral and aortic valve calcifications, aortic plaques and patent foramen ovale, are associated with cardioembolic events. Finally, acute ischemic or hemorrhagic cerebral events, epileptic seizures, cerebral traumas, and brain tumors can be associated with electrocardiographic abnormalities, catecholaminergic myocardial damage, or arrhythmias.
