Things to know about heart attack symptoms

Although heart attack symptoms often appear to occur suddenly, they are actually the result of important warning signals the body gives days or even months in advance. Heart attacks, which are increasingly common today regardless of age, can help prevent life-threatening consequences when recognized early.

In the rest of our article, we will discuss in detail what a heart attack is, how it develops, which risk factors cause it, and what symptoms it presents, helping you interpret the early warning signs correctly.

What is a heart attack?

Simply put, a heart attack occurs when the vessels that supply blood to the heart (coronary arteries) suddenly become blocked, depriving the heart muscle of oxygen. Medically referred to as myocardial infarction, this condition involves the interruption of oxygen and nutrient flow that the heart needs to continue pumping blood to the body.

The heart muscle is one of the most dynamic tissues in our body and requires a constant supply of oxygen. When blood flow stops or significantly decreases, heart muscle cells deprived of oxygen begin to suffer damage rapidly.

What makes this process critical is that if left untreated, the damage to heart tissue becomes permanent and directly threatens the vital functions of the heart. Therefore, in response to the question “What is a heart attack?”, it can be thought of not as the failure of an organ, but as the blockage of the biological system that keeps that organ alive.

How does a heart attack happen? How long does a heart attack last?

One of the most common questions when thinking about heart attacks, which can occur in both young and older individuals today, is “How does a heart attack happen?” At this point, it would be accurate to say that a heart attack usually occurs as the sudden eruption of a silent buildup that has been developing over years.

Over time, structures called plaques, which are made up of cholesterol and other substances, accumulate on the inner walls of the vessels supplying the heart. This condition, known as atherosclerosis, narrows the vessels but does not always result in a heart attack.

The moment of a heart attack begins when the thin layer covering these plaques suddenly ruptures or tears. The body perceives this as an injury and sends platelets to the area. The resulting clot completely blocks the vessel, stopping blood flow within seconds.

The duration of a heart attack is often misunderstood. This is not a process that lasts seconds, but one that can extend over hours. Symptoms usually last longer than 15–20 minutes and may continue for hours. Medically, the most critical period is the first 6 hours.

If no intervention is made within the first 60–90 minutes, the damage to the heart muscle becomes permanent. Therefore, it is important to consider the question “How long does a heart attack last?” from this perspective and to remember the importance of intervention in the early hours.

What causes a heart attack?

One of the main factors leading to a heart attack is the loss of elasticity in the vessel walls and the process of hardening of the arteries. The leading causes that accelerate this process can be listed as follows:

• Smoking: Smoking directly triggers plaque formation by irritating the inner surface of the vessels and increases the tendency of the blood to clot.
• High blood pressure (hypertension): The high pressure exerted by blood on vessel walls over time damages their structure and creates a basis for ruptures.
• Cholesterol imbalance: High levels of bad cholesterol (LDL) in the blood form the main component of plaques that cause vascular blockage.
• Diabetes: High blood sugar damages the inner layers of blood vessels and can increase the risk of a heart attack by two to four times.
• Sedentary lifestyle and obesity: Excess weight and low physical activity, which force the heart to work harder, disrupt metabolic balance and indirectly threaten vascular health.
• Genetic factors and age: A family history of early heart disease and the natural wear of vessels with advancing age increase the risk of a heart attack.
• Chronic stress: Hormones released during intense stress raise blood pressure and strain the heart rhythm, making stress an important trigger factor.

These factors, alone or combined, significantly increase the risk of a heart attack by damaging the structure of blood vessels.

What are the heart attack symptoms? What is the pulse during a heart attack?

The most typical sign of a heart attack is a feeling of pressure, tightness, or heaviness in the center of the chest. However, when we address the question “What are the symptoms of a heart attack?”, we see that these symptoms are not limited to the chest alone.

Some of the other prominent symptoms include:

• Referred pain: Discomfort in the chest may spread to the left arm, neck, jaw, back, or stomach area.
• Shortness of breath: Sudden breathing difficulty that does not improve with rest, with or without chest pain, may be a sign of a heart attack.
• Cold sweating and nausea: Cold sweating accompanied by a sense of fear of death, indicating that the body is under intense stress, is one of the most distinctive symptoms.
• Extreme fatigue: A sudden and overwhelming feeling of exhaustion may occur without any apparent reason.

One of the most frequently asked questions is about the pulse rate during a heart attack. It should be clearly stated that there is no standard pulse rate that can be observed in everyone during a heart attack.

During a heart attack, the pulse may be very fast (tachycardia) or very slow (bradycardia) due to the body going into shock. In some cases, it may even remain within normal ranges. Therefore, saying “my pulse is normal, so I am not having a heart attack” is a major medical misconception.

Is numbness in the fingers of the left hand a symptom of a heart attack?

Numbness in the fingers of the left hand can be a symptom of a heart attack, but it usually does not occur alone. As mentioned earlier, this is explained by the mechanism of referred pain. The following situations are distinguishing:

• If accompanied by chest pain and shortness of breath, the risk is high
• If it increases with exertion, it may be heart-related
• If it changes with position, it is usually due to nerve compression

If only your fingers are numb and your general condition is good, this is usually an orthopedic or neurological issue. However, if this numbness is accompanied by other discomforts in the upper part of your body, you should consult a specialist without delay.

Frequently Asked Questions

Can armpit pain occur during a heart attack?

Armpit pain or discomfort can be felt during a heart attack. The referred pain mechanism mentioned earlier also applies here. The heart is located inside the rib cage, very close to the armpit and the left arm. When the heart muscle is under strain, the pain signals it sends can stimulate the nerve networks between the chest wall, armpit, and shoulder blade.

To distinguish between heart-related armpit pain and pain caused by non-cardiac reasons (such as muscle pain or injury), the following points may help:

• Heart-related pain feels like pressure
• It does not change with touch
• It may increase with exertion

Sometimes, armpit pain can be more noticeable than chest pain itself. Therefore, especially in individuals at risk, unexplained pain in this area should be evaluated by a specialist.

Are heart attack symptoms different in women?

Heart attack symptoms in women can differ significantly from those in men, and unfortunately, this can sometimes lead to delayed diagnosis. The thinner structure of women’s cardiovascular system compared to men is one of the main reasons why symptoms may appear more subtly. Common symptoms in women that may overshadow classic chest pain include:

• Extreme fatigue
• Back and jaw pain
• Nausea and indigestion
• Shortness of breath and anxiety

Women often interpret these symptoms as fatigue or stress and may delay seeking medical help. However, these signals may be the heart’s call for help. Therefore, if you experience unusual fatigue or pain, you should consult your doctor to rule out or confirm the possibility of a heart-related problem.

What are the symptoms of a heart attack in men around age 40?

Although it is difficult to strictly categorize heart attack symptoms by age, symptoms in men around the age of 40 are generally more pronounced compared to women. The body tends to send clearer signals that something is wrong. Common symptoms include:

• Pressure in the center of the chest
• Intense cold sweating
• Pain in the left shoulder and jaw
• A burning sensation that may be confused with heartburn, which can indicate a blockage in the lower wall of the heart

The most common challenge in this age group is that patients often attribute symptoms to “work stress” or “muscle pain” and delay going to the hospital. However, since the vascular structure is still relatively elastic at this age, the heart muscle may be unprepared for sudden blockage, making the speed of intervention critically important.

How can silent heart attack symptoms be recognized?

A silent heart attack (silent ischemia) can develop without noticeable pain. These symptoms are especially seen in people with diabetes and in women. Silent heart attack symptoms include:

• Persistent fatigue
• Mild chest discomfort
• A sensation of heartburn
• Cold sweating and dizziness

A silent heart attack is often detected during a routine ECG performed days or weeks later. If you have diabetes or high blood pressure, it is important to take these symptoms seriously.

What are the symptoms of a false heart attack?

This condition, medically referred to as non-cardiac chest pain, is commonly known as a false heart attack. These pains can mimic a heart attack so well that panic is completely natural. However, some key differences provide clues that the pain is not heart-related.

Some of the prominent symptoms of a false heart attack include:

• Localized pain: Sharp, stabbing, momentary pain felt in a single point in the chest
• Tenderness that changes with pressure: Increased pain when pressing the affected area with a finger
• Changes with movement and position: The nature of the pain changes when turning the body, raising the arm, or bending
• Short attacks lasting seconds: Pain that lasts only a few seconds
• Stabbing pain with deep breathing: Sudden sharp pain felt in the chest wall when breathing deeply, sneezing, or coughing
• Burning after meals: A burning sensation behind the breastbone, especially after heavy meals or when lying on the back
• Psychological distress: Chest tightness during panic attacks, accompanied by restlessness and the urge to move constantly

Although these symptoms are not necessarily related to a heart attack, it is still important to seek professional medical advice if you experience chest pain to avoid taking risks.
