Anterior wall ischemia is dangerous? is it curable?

Anterior wall ischem: Ia can be very dangerous. It is also "curable" (i prefer the term treatable in this case) with stents or surgery.

Yes: Anterior wall ischemia means there is a risk of having a heart attack. Treatment at this point is to see a cardiologist for full evaluation of the blood supply to the heart. Depending on the findings, treatment could be diet, medication, angioplasty with a balloon catheter, or even an operation.

Heart attack: Or angina. It should be addressed by a cardiologist immediately.

Arterial blockage.: Ischemia in areas of the heart, as you have related, infers that the arteries that feed these parts of the heart are narrowed such that blood flow through them reduces with exertion. It means these areas of the heart are vulnerable and further testing is needed and intervention may be necessary. Could be treatable if managed quickly.
