[Electrocardiographic changes in acute and past cerebral stroke]
Insights
Cerebral arterial thrombosis cases showed the most frequent myocardial infarctions. Cerebral embolism was linked to arrhythmias, while cerebral hemorrhages had no clear ECG changes.
Area of Science:
- Neurology
- Cardiology
- Pathology
Context:
- Analysis of 617 cerebral stroke cases (534 acute, 83 past) treated between 1966-1972.
- Classification into four groups: cerebral hemorrhage, embolism, arterial thrombosis, and circulatory failure.
- ECG changes were analyzed in all patients, with autopsy findings for deceased individuals.
Purpose:
- To investigate the relationship between different types of cerebral strokes and electrocardiographic (ECG) changes.
- To determine the prevalence of specific stroke types and associated cardiac conditions.
Summary:
- Cerebral arterial thrombosis (37%) was the most common acute stroke type, frequently associated with acute myocardial infarction.
- Acute cerebral circulatory failure accounted for 35% of cases, with myocardial ischemia observed in 15%.
- Cerebral embolism (24%) correlated with arrhythmias (19%), whereas cerebral hemorrhages showed no unequivocal ECG changes. Atheromatous coronary artery disease was present in all stroke patients with myocardial infarction.
Impact:
- Highlights the significant association between cerebral arterial thrombosis and myocardial infarction.
- Underscores the link between cerebral embolism and cardiac arrhythmias.
- Suggests a complex interplay between cerebrovascular events and cardiovascular health, particularly in the context of coronary artery disease.
Abstract:
An analysis of 617 cases of cerebral strokes was done, including 534 acute and 83 past ones treated in the years 1966-1972. The patients were divided into 4 groups: I -- cerebral haemorrhage, II -- cerebral embolism, III -- cerebral arterial thrombosis, IV -- failure of cerebral circulation. The classification was based on clinical criteria and in dying patients also on autopsy findings. ECG changes were analysed in all patients. In the acute period of stroke the greatest proportion of cases were cerebral arterial thrombosis (197 cases --37%) and in this group acute myocardial infarctions were most frequent. This group was followed by cases of acute cerebral circulatory failure (191 cases -- 35%). The electrocardiographic correlate of the cerebral changes were in this group signs of myocardial ischaemia (84 cases -- 15%). Cerebral embolism (134 cases -- 24%) was associated with arrhythmia (109 cases --19) of various origin. In the group of cerebral haemorrhages (95 cases -- 17%) no unequivocal ECG changes were observed. In all patients with myocardial infarction during cerebral stroke atheromatous changes of coronary arteries were present. No correlation was observed between the location of the cerebral focus and the type of electrocardiographic changes.
