How Is a Heart Attack Diagnosed?
Tests include: Electrocardiogram (ECG). This first test done to diagnose a heart attack records the electrical activity of your heart via electrodes attached to your skin. Because injured heart muscle doesn't conduct electrical impulses normally, the ECG may show that a heart attack has occurred or is in progress.

Beside this, can a blood test tell if you've had a heart attack?

Fifty years ago, doctors had to rely on a person's symptoms and sometimes hard-to-interpret changes on an electrocardiogram to determine if a heart attack was under way. Today, blood tests are available that can detect the chemical signature of dying heart cells. The blood test preferred today is called troponin.

Similarly, how long after a heart attack can it be detected? In a study published last month looking at low-risk patients, researchers found that the new FDA approved high-sensitivity troponin test could help doctors identify patients having a heart attack in under three hours as opposed to six to nine hours under less sensitive troponin tests.

Subsequently, question is, what does a mini heart attack feel like?

It can feel like an uncomfortable pressure, squeezing, or pain. Discomfort in other upper-body areas, such as one or both arms, the back, the neck, the jaw, or the stomach. Shortness of breath before or during chest discomfort. Breaking out in a cold sweat, or feeling nauseated or lightheaded.

It is called a silent heart attack, or medically referred to as silent ischemia (lack of oxygen) to the heart muscle.
