Coronary ischemia effects? Do a few heart muscle cells die each time you have angina?

Not necessarily. Angina is a symptom of chest discomfort. Heart cells die only when the blood supply to the heart is stopped for at least 20 minutes. Angina may occur with no stoppage of blood to the heart, or it may occur in the presence of a damaging heart attack, known as myocardial infarction.
Depends. You can think of angina as similar to the muscle "burn" you feel after prolonged exercise. When the amount of blood flow is not enough to clear the "lactic acid" that is produced with muscular activity there is a burning sensation. If the insufficient blood flow (and oxygen) remains there can be tissue damage and even death. If you are experiencing angina you need to get checked asap.

Would angina usually hurt where the heart muscle is in the chest? My pain is a little higher than the hearts main cetre and doesn't go to the left

EKG showed 'hardening' of heart muscle. Just had a SV Ischemia show on CT scan. Is this connected? Does Arrythmia cause the hardening?

Not sure . Not sure how an ECG can show hardening of heart muscle. It could show signs that may be related to previous damage of heart muscle. Damage of heart muscle can cause arrhythmia. Most arrhythmias, unless left uncontrolled for long periods of time do dot cause heart damage. . Read more...

When someone gets angina for a few minutes due to coronary disease, does it scar the heart or damage it? Or is it just heart attacks that damage muscle.

Probably Not. Brief episodes of angina likely do not cause any measurable heart damage. They are, however, a very important warning sign and should not be ignored. If the frequency/duration/severity of anginal attacks is increasing or if someone has new onset angina that hasn't been evaluated yet, then it is important to see a doctor asap. Read more...

I take s digoxin.25 mg after I had thrombi from 2 years, can digoxin rebuild my heart muscle. Ef is32%.Iam47years, thanks?

No it will not rebui. Digoxin increses the myocardial contractibility and decreses the heart rate.It does improve ejection fraction and is used in association with other drugs like ace inhibiters, beta blockers, diuretics but it can not rebuild your heart muscle.Research is being done with stem cells for rebuilding heart muscles, with some promosing results.

Had a heart cath. Told I had a thickened heart muscle. How serious? Can I reduce thickness?

Yes. Heart cath does not diagnose a thickened heart muscle. An echocardiogram or ultrasound does, unless it is a more serious condition known as hypertrophic cardiomyopathy. The more common condition is LVH or hypertrophy of the heart which is caused by uncontrolled high blood pressure. Reversing the blood pressure can reverse some of the LVH particularly with ace inhibitors. Read more...
