From the Guidelines
A massive cerebrovascular accident (CVA) or stroke can lead to death through several mechanisms, primarily including brain herniation, respiratory complications, cardiac complications, pulmonary embolism, sepsis, and multiorgan failure, as supported by the most recent and highest quality study 1.
Causes of Death
The potential causes of death in a patient who has suffered from a massive cerebral vascular accident (CVA) or stroke are multifaceted and can be categorized into several key areas:
- Brain herniation due to severe cerebral edema, which occurs when swelling pushes brain tissue against the skull, disrupting vital functions.
- Respiratory complications, including aspiration pneumonia from impaired swallowing, hypoventilation from brainstem damage, or neurogenic pulmonary edema.
- Cardiac complications such as arrhythmias, myocardial infarction, or neurogenic stunned myocardium, which can occur due to autonomic dysregulation following the stroke.
- Pulmonary embolism from deep vein thrombosis due to immobility.
- Sepsis resulting from hospital-acquired infections, particularly urinary tract infections or pneumonia.
- Multiorgan failure, which may develop as a cascade effect from the initial brain injury.
Management and Prevention
Management focuses on preventing these complications through measures like intracranial pressure monitoring, ventilatory support, DVT prophylaxis, early mobilization, and infection prevention, as emphasized in 1. Key aspects of management include:
- Early assessment and intervention for dysphagia and aspiration risk, with the use of formal screening protocols like the water swallow test, as highlighted in 1.
- Monitoring for cardiac complications and implementation of preventive strategies for deep vein thrombosis and pulmonary embolism.
- Aggressive infection control measures to prevent hospital-acquired infections.
- Consideration of palliative care for patients with severe, fatal brain injuries, as discussed in 1.

From the Research
Potential Causes of Death in CVA Patients
The potential causes of death in patients who have suffered from a massive cerebral vascular accident (CVA) or stroke can be attributed to several factors, including:
- Neurological causes, such as brain swelling and inability to protect the airway 2
- Cardiac causes, such as cardiac arrest or cardiac arrhythmias 2
- Respiratory causes, such as pneumonia, which is a common complication of stroke 3
- Aspiration, which can occur due to dysphagia, a condition where patients have difficulty swallowing 4, 3
Complications in the Acute Stages of Stroke
Complications in the acute stages of stroke can vary depending on factors such as age, brain areas involved, and the presence of concomitant systemic disease 5. These complications can include:
- Generalized tonic-clonic seizures or status epilepticus 2
- Brain swelling, which can lead to inability to protect the airway 2
- Bilateral pulmonary edema from congestive heart failure 2
- Pneumonia, which can be caused by aspiration or other factors 3
Importance of Early Recognition and Management
Early recognition and management of these complications are crucial to prevent poor outcomes in patients with ischemic hemispheric stroke 2. Nurses play a pivotal role in the care of stroke patients, and their assessment skills and knowledge can enable early recognition of signs and symptoms foreboding potentially disastrous complications 5.
