How to determine if I am having a heart attack or it's just "angina" ?

Classically: Angina pectoris =substernal pressure, pain with radiation to the neck or left or right arm and shoulder. Some will have abdominal pain-and be confused with gallbladder or stomach symptoms. Ladies seem to have less classic// or tolerate pain better than men. Relief with Nitroglycerin is very suggestive. A feeling of impending doom, pallor, sweating suggest a bad day! ...Read more

Pacemaker (Definition)

A pacemaker is a device which sends electrical signals to the heart triggering heartbeats when needed. There are many ways to implant and configure a pacemaker; it may beat the top chambers (atria), lower chambers (ventricles) or both. Some systems stimulate both the left and right ventricles together. Pacemakers generally treat abnormally slow heart rhythms and certain ...Read more

Can anxiety cause a silent heart attack or angina?

Of course, if their is any question, one should seek care by their pcp or er. ...Read more

If the pacemaker can not prevent the heart attack, what happens to it during the heart attack?

If the pacemaker can not prevent the heart attack, what happens to it during the heart attack?

Pacer: A heart attack usually doesn't affect an electronic pacemaker. The device will help prevent the heart from slowing excessively and usually won't be affected by rapid heart action. If a cardiac arrest occurs and defibrillation is necessary, the electric shock could possibly affect the pacer circuitry. ...Read more

Dad had a massive heart attack 6 months ago. his heart working at 29% they said he needs a pacemaker. an he won't have it done he thinks he's fine??

He probably was told: that he needs a defibrillator not a pacemaker. A weakened heart muscle places him at significant risk for sudden cardiac death. He could feel just fine...until he dies! A defibrillator would prevent this sudden unexpected terminal event. He should be encouraged to discuss this more openly with his health care professionals. ...Read more

What exactly does "noncritical disease" of "up to 20 percent" mean on heart cath report? Why would this be low risk for heart attack/unstable angina?

Angina (Definition)

Angina is chest pain that is caused by poor blood flow to the heart muscle. Angina is not an actual disease, but rather a symptom of an existing heart problem. Most commonly, this underlying problem is due to an obstruction of the coronary blood vessels that surround the heart. There are different types of angina including stable angina, unstable ...Read more

Heart Attack (Definition)

Heart attack is a life-threatening condition in which the blood vessels that supply the heart becomes occluded and thus the heart itself is not longer receiving any blood flow. Without this blood flow, the heart muscle dies and cannot pump blood to the ...Read more
