When does a heart attack occur?; A heart attack is caused by ischemia, that is, by a reduction or complete interruption of blood flow to a specific part of the heart. When ischemia persists for a period longer than the myocardial cells can maintain their homeostasis, serious damage and necrosis occur in that specific area.

What are the symptoms of a heart attack?;

The symptoms of a heart attack are not the same for everyone. The main ones are:

a tightness in the chest
chest pain that radiates to the jaw, neck, shoulder, and back
pain or numbness in the left arm or right arm or both
pain in the upper abdomen
difficulty breathing
nausea – vomiting
heavy sweating
pale appearance
fatigue

The severity of symptoms varies from patient to patient. Some may experience more severe pain and other symptoms, while others may experience milder, almost imperceptible symptoms (especially those with diabetes).

What are the factors that increase the risk of developing it?;

The factors that cause coronary artery disease are also likely to cause a heart attack. These are as follows:

high cholesterol
smoking
diabetes mellitus
high blood pressure
family history
obesity
lack of exercise
the use of methamphetamine or cocaine

Heart Attack: How Is It Diagnosed?;

The diagnosis is based on the patient’s clinical presentation. With the help of an electrocardiogram and an echocardiogram, the doctor is able to assess the heart’s activity and identify the damaged area. At the same time, a blood test is performed to detect elevated levels of cardiac enzymes, which indicate necrosis of a portion of the myocardium. Finally, through cardiac catheterization (coronary angiography)—which uses X-rays and a special contrast agent that is injected— the doctor can precisely locate the areas of the coronary arteries that have been damaged.

Heart Attack and Treatment

Treatment for a heart attack is divided into three stages:

inhibition of the blood clotting process
reopening of the blocked artery
managing potential complications.

Time is of the essence for the successful treatment of a heart attack. As soon as a patient experiences any of the above symptoms, they must seek medical help. Delay can be fatal and may cause irreversible damage or even death.

Heart Attack – Possible Complications

Common complications include arrhythmias and myocardial damage. The longer the opening of the artery is delayed, the greater the risk of these complications occurring. However, even after the artery is opened, the risk of complications remains during the first 24 hours following the onset of the heart attack. For this reason, the patient is admitted to an intensive care unit and monitored by specialized medical staff.

Heart Attack: How Can You Reduce Your Risk of Having One?;

There are certain behaviors we can adopt to reduce the risk of having a heart attack, such as:

quitting smoking
daily physical exercise
a healthy diet
weight loss

To sum up…

A heart attack occurs when the amount of blood reaching the heart is insufficient for it to function properly. The symptoms and severity of a heart attack vary from case to case. If someone experiences heart discomfort, even if it is mild, they should schedule an appointment with a cardiologist. Under no circumstances should they ignore warning signs, as there is a high probability that they have already suffered a mild heart attack without realizing it. Usually, a mild episode is followed by a more serious one.

Silent heart attack

Silent heart attacks most often affect women and people who have been diagnosed with diabetes.

Some of the symptoms associated with a silent heart attack include unexplained fatigue, shortness of breath, and discomfort in the throat, neck, jaw, or one of the limbs. Other patients report experiencing heartburn after the episode.

Silent Heart Attack: How to Recognize It

People who have had a silent heart attack may not see their doctor until weeks or even months later, at which point they are informed of the episode. The diagnosis is usually made with the help of an electrocardiogram, as this allows the doctor to determine the extent of the damage to the heart muscle. An even more accurate picture of the heart’s condition is provided by a test called an echocardiogram.

The reason for seeing a doctor after a silent heart attack is often the persistent fatigue and shortness of breath that the patient experiences. In some cases, these symptoms are caused by a leak in the heart’s mitral valve or by scar tissue that formed in the heart as a result of the heart attack.

Serious complications that may arise following an undiagnosed silent heart attack include heart failure, heart rhythm disturbances (arrhythmias), and loss of consciousness (syncope).

Experts point out that the mild nature of the symptoms does not mean that a visit to the doctor is unnecessary. Discomfort that persists for several minutes—especially if it seems unexplained and has not occurred before—should not be dismissed and must be evaluated by a doctor.
