What can result from a blockage in coronary arteries?

A blockage in the coronary arteries can restrict blood flow to the heart muscle. This can lead to several conditions, primarily angina, which is chest pain or discomfort resulting from reduced blood flow to the heart. Angina manifests as a warning sign that the heart is not receiving enough oxygen-rich blood, which is often due to atherosclerosis or other forms of blockage.

While a blockage might contribute to other conditions like heart attacks or stroke, angina is the direct symptom experienced when the coronary arteries are compromised. Heart attacks occur when a blockage is severe enough to completely stop blood flow, leading to the death of heart muscle tissue. Strokes, while also related to blood flow issues, typically involve the arteries supplying the brain rather than the heart. Therefore, angina is the most immediate and direct consequence of a blockage in the coronary arteries, highlighting the importance of recognizing its signs and symptoms for early intervention.
