Silent heart attacks, also known as asymptomatic or "silent" myocardial infarctions (SMIs), are a serious concern for individuals with diabetes. This article explains the increased risk of a silent heart attack in diabetics along with case study presentations.
Silent heart attack
A silent heart attack occurs when the heart muscle is damaged by a lack of blood flow, but the individual does not experience the typical symptoms of chest pain or discomfort. In fact, many individuals may not even be aware that they have had a heart attack.
Silent heart attack in diabetes
Individuals with diabetes are at an increased risk for silent heart attacks due to the disease's impact on the cardiovascular system. Diabetes can cause damage to the blood vessels, making them more susceptible to blockages and reducing blood flow to the heart. This can lead to the formation of plaques in the arteries, which can rupture and cause a heart attack. Additionally, diabetes can cause changes in the heart's structure and function, making it more vulnerable to damage from a lack of blood flow.
Uncontrolled diabetes
The risks of silent heart attacks are further increased in individuals with uncontrolled diabetes. When blood sugar levels are consistently high, it can lead to damage to the blood vessels and nerves, making them more susceptible to blockages and reducing blood flow to the heart. High blood sugar levels can also lead to a thickening of the heart muscle, which can further increase the risk of a silent heart attack.
