De subitaneis mortibus. XXVIII. Apoplexy of the heart

Area of Science:

• Cardiology
• Neurology
• Pathophysiology

Background:

• Apoplexy of the heart presents as sudden or recurring cardiac instability.
• Pathophysiological mechanisms of cerebral apoplexy have counterparts in cardiac apoplexy.
• These cardiac events can occur with or without myocardial infarction.

Purpose of the Study:

• To explore the mechanisms of cardiac apoplexy.
• To highlight the link between cardiac vascular accidents and neurological manifestations.
• To emphasize the importance of considering cardiac apoplexy in unexplained syncope and sudden death.

Main Methods:

• Review of pathophysiological mechanisms of cardiac apoplexy.
• Analysis of vascular events affecting cardiac conduction centers.
• Correlation of cardiac events with clinical presentations like syncope and neurological symptoms.

Main Results:

• Mechanisms include thrombosis, embolism, and vessel rupture in cardiac nodes and His bundle.
• Cardiac apoplexy can manifest without significant ventricular myocardial infarction.
• Acute vascular accidents in cardiac conduction centers are implicated in unexplained epilepsy, seizures, and syncope.

Conclusions:

• Cardiac apoplexy is a significant cause of sudden cardiac death and syncope.
• Neurologic symptoms can be secondary to cardiac vascular events.
• Cardiac apoplexy warrants greater consideration in diagnosing unexplained neurological and cardiac conditions.
