Insights
Protecting the heart in acute stroke patients may reduce mortality. Elevated cardiac biomarkers like NT-proBNP indicate heart risk and higher mortality, suggesting therapeutic interventions are warranted.
Area of Science:
- Cardiology
- Neurology
- Biomarkers
Context:
- Acute stroke mortality remains a significant concern despite existing damage limitation strategies.
- Cardiovascular factors, including cardiac impairment and injury, play a critical role in acute stroke outcomes.
- The neurohumoral response in stroke can lead to cardiac stress and damage.
Purpose:
- To review the influence of cardiovascular factors, specifically NT-proBNP, on stroke mortality.
- To evaluate the prognostic value of cardiac biomarkers in acute stroke patients.
- To explore potential therapeutic strategies targeting cardiac protection in stroke.
Summary:
- Cardiovascular abnormalities, evidenced by ECG changes, tachycardia, and elevated cardiac biomarkers (Troponin, NT-proBNP), are associated with increased mortality in acute stroke.
- NT-proBNP levels are particularly significant, showing a strong correlation with short- and long-term mortality, sometimes exceeding the predictive power of clinical stroke severity.
- Neurohumoral activation and Renin-Angiotensin-Aldosterone-System (RAAS) changes in stroke contribute to cardiac stress, but also present potential targets for cardioprotective therapies.
Impact:
- Identifying occult cardiac damage in stroke patients is crucial for understanding mortality.
- Investigating cardioprotective interventions, using existing or novel drugs (e.g., beta-blockers, RAAS inhibitors), could significantly reduce stroke-related deaths.
- This research highlights the critical brain-heart axis and the potential for a broad therapeutic window for cardiac interventions in acute stroke management.
Background:
Measures of damage limitation for acute stroke have not produced substantial benefit to reduce stroke mortality. Search continues for measures to reduce stroke mortality.
Methods:
Literature review for influence of cardiovascular factors, specifically the value of NT proBNP (a sensitive index of cardiac impairment) for stroke mortality.
Results:
Cardiovascular factors, in particular cardiac failure, adversely influence acute stroke mortality. There is evidence of cardiological abnormality in acute strokes as indicated by ECG changes and tachycardia secondary to neurohumoral changes in acute strokes. Patients with ECG abnormality, tachycardia, dysrrhythmia and elevated levels of nor-epinephrine in acute stroke phase have higher mortality. Recent studies reveal that Troponin (measure of cardiac injury) and NT-proBNP (measure of cardiac function impairment) are elevated in acute stroke patients, in response to the activated Renin-Angiotensin-Aldosterone-System and other neurohumoral changes, as a protective mechanism for sympatho-inhibitory activity. Patients with elevated troponin have a higher mortality. Similarly elevated NT-proBNP has been reported to be associated with higher short and long-term mortality. In one study all patients who died at 4 months had NT-proBNP levels above the median, no patient with NT-proBNP below the median value died. Two studies revealed that NT-proBNP is more significant than clinical stroke severity for stroke mortality. Protection of myocardium in stroke patients may be possible by the use of drugs such as beta-blockers and the drugs acting on RAAS. Reduction of mortality in studies of candesartan (ACCESS study) and prior betablockers is one such example. Heart is at risk in acute strokes and protecting heart makes sense to reduce stroke mortality.
Conclusion:
Some stroke patients die due to occult cardiac damage and functional impairment in acute phase due to common risk factors. This relationship between brain and heart needs evaluation. Protection of heart with currently available or new drugs in acute strokes is worth investigating since this intervention could be applied to a large proportion of acute stroke patients over a wide time window.

Regulation of Stroke Volume
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
