Does angina increases the odds of heart attack? if i had an angina attack over the weekend, does that mean i'm at increased risk of having a heart attack?

If : If you experience angina at rest, or are developing it frequently with minimal exertion, then you are having what is called unstable angina. This does mean you are at an increased risk for having a heart attack, and you should be evaluated immediately. Unstable angina falls in a category of what are called acute coronary syndromes. Unstable angina indicates that atherosclerotic plaques in the artery may be unstable and at risk of rupturing and completely blocking the artery. If this occurs, this causes a heart attack. You should contact your cardiologist's office for further direction, or if experiencing unstable angina after hours then you should be evaluated in an emergency room.

Very possibly: Heart attack risk increases when angina accelerates. If your angina is occurring with increased frequency, duration, severity or occurs at a lower workload, you should see your doctor as your risk is increased. If your angina came on over the weekend doing something that always causes it, your risk is unchanged.
