Summary
Elevated body temperature after stroke and intravenous thrombolysis treatment is linked to poorer patient outcomes. Managing fever is crucial for improving recovery after stroke treatment.
Area of Science:
- Neurology
- Cardiovascular Medicine
- Critical Care Medicine
Background:
- Body temperature fluctuations after acute ischemic stroke can impact patient prognosis.
- Intravenous thrombolysis with tissue plasminogen activator (IV tPA) is a critical treatment for acute ischemic stroke.
- Understanding the role of temperature in stroke recovery is essential for optimizing treatment strategies.
Purpose of the Study:
- To investigate the association between baseline body temperature and post-stroke temperature changes with functional outcomes in patients receiving IV tPA.
- To determine if fever after stroke and thrombolysis treatment affects recovery.
- To analyze temperature parameters, including area under the curve relative to baseline (AUCBL) and relative to 37°C (AUC37), in relation to patient outcomes.
Main Methods:
- Retrospective analysis of 100 consecutive patients treated with IV tPA.
- Monitoring body temperature for the first 24 hours post-treatment.
- Calculating temperature evolution using AUCBL and AUC37.
- Correlating temperature parameters with functional outcomes, including favorable and unfavorable responses to tPA.
Main Results:
- Patients with unfavorable outcomes exhibited significantly higher temperature elevations (+1°C vs +0.6°C) and higher AUCBL values compared to those with favorable outcomes.
- Hyperthermia relative to baseline was more frequent in patients with unfavorable outcomes (82% vs 56%).
- After adjusting for baseline characteristics, hyperthermia relative to baseline was associated with reduced odds of a good outcome (OR 0.34, 95% CI 0.10-0.95).
Conclusions:
- Post-thrombolysis hyperthermia relative to baseline temperature in the 24 hours following IV tPA administration is significantly associated with unfavorable functional outcomes.
- These findings highlight the importance of temperature management in stroke patients undergoing thrombolysis.
- Further research may explore targeted fever reduction strategies to improve outcomes in this patient population.

Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
Increased Body Temperature
A body temperature above 38°C (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in response to an infection or illness.
Decreased Body Temperature
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by sustained extreme cold exposure, and severe...
Hemorrhagic Stroke ll: Pathophysiology
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
Assessing Body Temperature - Temporal Artery
Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.
Step 3: Assess the patient's forehead...

Blood Studies for Cardiovascular System I: Cardiac Biomarkers
Cardiac biomarkers are enzymes, proteins, and hormones released into the blood when cardiac cells are injured. They are powerful tools for triaging.
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...
