Cerebrovascular incidents after myocardial infarction.

Abstract

(Young et al., 1960). Correlation between the degree of atheroma of coronary and carotid arteries is likewise high (Young et al., 1960;Mitchell and Schwartz, 1965). When necropsy evidence of myocardial infarction is made the starting point, the prevalence of carotid stenosis is again high, the lumen of the sinus being reduced by half in 59% of men with myocardial infarction against 35% in unselected necropsies (Mitchell and Schwartz, 1965). Conversely, when atheroma of the carotid sinus is the starting point the prevalence of myocardial infarction rises from 8% in cases with mild atheroma to 67% in severe cases (Martin et al., 1960).Embolisation from the heart to the carotid and cerebral circulation is also a common pathological finding. In a series of cases of occlusion of the internal carotid artery 20% were caused by emboli

Mechanism of late stroke after myocardial infarct: the Lausanne Stroke Registry.

“…After stepwise multiple logistic regression, only age, sex, history of vascular claudication, and hypercholesterolaemia were linked to the presence of old myocardial infarction in stroke patients, according to: (25)]. There was no significant difference between patients with old myocardial infarction, patients without old myocardial infarction, and patients with another potential cardiac source of embolism for the topography of the cerebral infarcts.…”

Gleichzeitiges Auftreten von Herz- und Hirninfarkten

“…Bei Myokardinfarkten kommt es in 2-4% der Falle gleichzeitig oder nach wenigen Tagen zu zerebralen Insulten, die in 2% als transitorisch ischämische Attacken ablaufen. In der Folge nimmt das Risiko erheblich ab, so daI sich das Vorkommen von Apoplexien im ersten Jahr nach einem Herzinfarkt nur noch auf 5 % erhöht (10,11,13,15,16,20). Von seiten der zerebralen Insulte betrachtet, findet man eine ahnliche Verteilung, denn nach akuten Schlaganfallen liegen bei 4-8% der Patienten im EKG Hinweise auf frische Myokardinfarkte vor, während in 14 % der Kurven Zeichen alterer Herzinfarkte bestehen (6, 14).…”
