What is one of the significant risks associated with untreated myocardial ischemia?

Heart failure
Diabetes
Stroke
Kidney damage

The correct answer is: Heart failure

Untreated myocardial ischemia significantly increases the risk of heart failure due to the prolonged lack of adequate blood flow to the heart muscle. When the heart does not receive sufficient oxygen-rich blood, it can lead to damage or weakening of the heart tissue. Over time, this may result in the heart being unable to pump effectively, leading to a state known as heart failure. In this condition, the heart struggles to meet the body’s demands for blood and oxygen, resulting in various symptoms such as fatigue, shortness of breath, and fluid retention. The relationship between myocardial ischemia and heart failure is well-documented, as ongoing ischemia can contribute to structural changes in the heart, such as hypertrophy and dilation, which are precursors to heart failure. In contrast, while diabetes, stroke, and kidney damage can be linked to cardiovascular health, they are not direct consequences of untreated myocardial ischemia in the same clear and immediate manner as heart failure. Therefore, heart failure stands out as a primary and significant risk associated with untreated myocardial ischemia.
