Myocardial infarction can be said to be the most serious disease with a high fatality rate and the main cause of sudden death!
Some people often ask: What kind of examination can I do to know if I will have a myocardial infarction? Is it an electrocardiogram? Or cardiac enzymes? Or a heart ultrasound? Or just do an imaging?
I understand very well the mood of the questioner and the answers they want to know.
But this is not the case, and no simple test can predict myocardial infarction. Most myocardial infarctions will have an alarm before the occurrence of myocardial infarction, but this alarm does not mean that you can do it when you want to have an examination. We will mention at the end, let’s talk about why these 4 common tests cannot predict myocardial infarction.
1. Electrocardiogram
ECG can diagnose myocardial infarction that has already occurred, but it cannot directly predict myocardial infarction that has not yet occurred. I had an electrocardiogram before, but the electrocardiogram could not directly show that he would have a myocardial infarction a month later, a week later, or a day later.
The electrocardiogram can only diagnose myocardial infarction that has already occurred blood vessel blockage.
Therefore, we usually do an electrocardiogram, which cannot predict when a myocardial infarction will occur in the future.
2. Cardiac enzymes
Is it said that myocardial enzymes can not diagnose myocardial infarction?
That’s true, but myocardial enzymes can only be diagnosed for myocardial infarction that has already occurred. When myocardial infarction occurs 2 hours after the occurrence of myocardial infarction, myocardial enzymes will gradually increase, reach a peak at 24-72 hours, and then gradually decrease until it returns to normal in about 7 days.
That is to say, blood is drawn to test for myocardial enzymes within 2 hours to 7 days after myocardial infarction, and myocardial enzymes are high.
If the blood test was done before, the myocardial enzymes were normal, even if it was just a myocardial infarction, the blood test was normal at this time, let alone before the myocardial infarction. . Therefore, after myocardial infarction, ECG is more rapid than myocardial enzymes in the diagnosis of myocardial infarction.
3. Heart ultrasound
Cardiac ultrasonography cannot diagnose coronary heart disease. Regardless of whether there is myocardial infarction, it is generally difficult to directly diagnose cardiac ultrasonography.
Only for people with old myocardial infarction and uncoordinated ventricular wall motion, color Doppler ultrasound can see poor ventricular wall activity, but it cannot predict or diagnose myocardial infarction.
4. Cardiac angiography
Some people say, should I go straight to a coronary CT or coronary angiography?
Coronary CT or angiography can see plaque in blood vessels, as well as blood clots. For myocardial infarction that has already occurred, of course, the location of the thrombus can be determined by angiography.
But if a person does not have a myocardial infarction, it is possible to check whether there is plaque in the blood vessels and whether it is coronary heart disease through these two.
But even if you see plaque, you can’t accurately predict whether a myocardial infarction will occur in the future.
The warning sign of myocardial infarction is called angina:
Most myocardial infarctions are preceded by angina.
When angina pectoris occurs, patients will have some feelings, and everyone is different. For example, they may experience chest pain, pain in the precordial area, chest tightness, suffocation, profuse sweating, and toothache. Pain, headache, throat tightness, back pain, shoulder pain, upper abdominal pain.
About 2-15 minutes of discomfort each time. It usually occurs after physical activity, labor, and exercise. The simple judgment is that there is no discomfort after physical activity, labor, and exercise, but recently, chest pain and pain in the precordial area have occurred. Toothache, headache, throat tightness, back pain, shoulder pain, upper abdominal pain, etc. At this time, it is highly suspected that it is a harbinger of myocardial infarction – angina pectoris.
At this time, it is necessary to seek medical treatment as soon as possible. After regular diagnosis and treatment, myocardial infarction can be prevented!
In short, most of the myocardial infarctions still have warnings, but you can’t rely on any test, but rely on the identification of angina pectoris.
Of course, for more people, we cannot wait for angina pectoris, but rely on a comprehensive healthy lifestyle, control of the three highs, and regular treatment of coronary heart disease.
