Dxing a Walking Heart Attack?

I've read about some people who've had heart attacks without necessarily knowing they've had them. This is probably a stupid question, but I was thinking about how diabetes is diagnosed if the blood sugar is a certain number after fasting or whatever. Is there a certain pulse rate and/or blood pressure which is considered a heart attack? I do understand that a heart attack is where a blood vessel in the heart bursts and vital signs an vary a lot from person to person, but I am wondering if there is some kind of number where heart attack is certain....

A heart attack is a myocardial infarction. It is caused when an artery supplying blood to the heart is blocked starving the heart muscle of oxygen.

The only "easy' tests I am aware of is an EKG where they look for " T- wave abnormalities" (don't ask me what a T-wave is). I understand the T-wave shows the heart is starved for oxygen. When I was in the hospital the nurses would come and yell at me when my T-wave "inverted" because I didn't press the nurses button. ( I didn't feel anything) There is also a blood test to check for an enzyme that the heart generates when it is starved for oxygen.

there's no certain BP for a person to experience heart attack as long as you adhere to the treatment regiment to control hypertension everything will be ok.. over 140/90 is hypertensive anyone who is high blood can experience heart attack..when your heart's workload is increased & it cannot compensate the changes & lack of blood supply on the myocardium (myocardial infarction) w/c also decreased cardiac output..

diabetes can predispose you to have hypertension, because of decrease renal perfusion your heart tends to compensate by increasing blood flow therefore increases heart's work load..& kidneys secretes angiotensin 2 w/c is a vasoconstrictor

Sound like you have a career as a doctor in your future. And no, there is no magic bullet, and the real number to be worried about is 0.

no changes in pulse rate or blood pressure indicate a heart attack...some people do have heart attacks with mild, vague, or absence of the typical complaints, no crushing chest pains, no sweating or nausea, no shortness of breath, etc....the EKG recording will show either a heart attack in progress, or one that has happened in the past....

There are patients who have nonspecific symptoms that can be mistaken for other ailments such as heartburn, indigestion, muscle spasm, etc. An ECG will show if a heart attack is happening, or has happened in the past.
