A stroke can cause 1 death every 4 minutes. To determine the patient's risk of stroke, the doctor measures certain characteristics of the heart, such as its size and pumping power. However, researchers have not had the tools to study how disease-induced changes in cardiac structure may affect heart function and blood flow. Today, an interdisciplinary team of scientists has found a new way to analyze blood flow through the upper blood collection cavity, the left atrium, which may lead to a better way to assess the risk of a patient suffering from a stroke. Using specialized computed tomography, the researchers used a visualized image of the heart's blood flow in two hearts: one with normal blood circulation and the other with abnormal blood flow due to heart disease. Their modeling shows that in a healthy heart, blood flows through the left atrium in a compact spiral shape, allowing it to flow out of the structure quickly. However, in an enlarged diseased heart, this spiral shape never completely forms, causing blood to linger in the left atrium. As a result, blood is more likely to accumulate there, forming a clot that causes a stroke. The team published the results in the journal Biomedical Engineering Chronicle, which was published a few days ago. Researchers hope that future work will enable physician practitioners to have the ability to assess the risk of stroke in patients using computerized visualizations of blood flow to the heart.
