Understanding a Heart Attack: February is Heart Month

February is recognized as Heart Month in both Canada and the United States, focusing on increasing awareness about heart and stroke health. As we take a moment to consider the significance of cardiovascular well-being, it’s essential to understand how to identify the symptoms of a heart attack. Being informed can truly make a difference, and knowing how to act in an emergency is crucial for saving lives.

One significant risk factor for heart disease is age. As people get older, their chances of developing heart issues increase. While men tend to face heart attacks at a younger age compared to women, the risk for women escalates notably after menopause. It’s important for all adults to keep this in mind as they age and to regularly assess their heart health.

What is a Heart Attack?

A heart attack, medically referred to as a myocardial infarction, happens when blood flow to a section of the heart is obstructed for a significant duration, often caused by plaque accumulation in the coronary arteries. When the heart muscle doesn’t receive enough blood, it can sustain damage or even perish. This condition can result in severe complications and may pose a serious risk to life if not addressed quickly.

Heart attacks can be categorized into two main types.

1. STEMI (ST-elevation myocardial infarction)
This type involves a complete blockage of blood flow in a coronary artery that delivers oxygen-rich blood to the heart. The total loss of blood flow can lead to the death of the entire thickness of the heart muscle that the artery supplies. This condition is reflected on an ECG (electrocardiogram), which will display ST-elevation indicating the area of damage to the heart wall.

2. Non-STEMI (Non-ST-elevation myocardial infarction)
In this case, there is a partial blockage of blood flow in a major coronary artery supplying the heart with oxygen-rich blood. Only a portion of the heart wall thickness is affected, and the ECG will not show any ST-elevation.

Symptoms of a Heart Attack

Main Symptoms

Heart attack symptoms can differ among individuals, but there are several common indicators to be aware of:

Chest Pain or Discomfort: Often regarded as the hallmark symptom, this may feel like tightness, pressure, or a squeezing sensation in the chest.

Shortness of Breath: Experiencing difficulty breathing, particularly at rest or with minimal exertion, can signal a heart attack.

Pain in the Arms, Back, Neck, Jaw, or Stomach: Discomfort in these areas, especially when paired with chest pain, may suggest a heart attack.

Nausea or Vomiting: Some individuals might feel nauseous, have indigestion, or even vomit as part of their heart attack symptoms.

Dizziness or Lightheadedness: A sensation of dizziness or faintness can serve as a warning sign of a potential heart issue.

Cold Sweat: Unexplained sweating, especially if it feels cold and clammy, can also indicate a heart attack.

Women, in particular, may encounter additional symptoms that are often overlooked. In addition to chest discomfort, they might experience shortness of breath, nausea, lightheartedness, or even symptoms resembling indigestion. These can easily be mistaken for less serious conditions, such as anxiety or digestive problems, highlighting the importance for everyone to pay attention to their bodies and seek medical advice if something feels off.

Additional Signs

Beyond the primary symptoms previously discussed, there are other indicators that might suggest a heart attack is occurring. These can include:

1. Exhaustion: Experiencing an unusual level of tiredness, even after a good rest, could serve as an important warning.

2. Feelings of Anxiety: A pervasive sense of dread or anxiety might be present during a heart attack.

3. Heartburn or Digestive Discomfort: Some individuals may confuse heartburn or indigestion with a gastrointestinal issue, when it could actually be heart-related.

4. Irregular Heartbeat: Experiencing palpitations, a racing heart, or irregular rhythms can signal potential heart issues.

5. Swelling: Noticeable swelling in the ankles, feet, or legs may indicate heart failure, which can increase the risk of a heart attack.

If you suspect that you or someone else may be having a heart attack, it’s crucial to respond swiftly. Here are the steps you should follow:

1. Contact Emergency Services: Immediately call your local emergency number to request assistance. Quick action is vital in these situations.
2. Chew Aspirin: If you have aspirin on hand and it’s safe for you to take, chew a tablet while waiting for help to arrive.
3. Stay Calm: Try to keep a calm demeanor and offer reassurance to the person experiencing symptoms. Anxiety can exacerbate the situation.
4. Ensure Comfort: Help the individual find a comfortable position, whether sitting or lying down, and loosen any restrictive clothing.

Always remember, it’s far better to seek medical attention and find out it’s not a heart attack than to overlook the signs. Your prompt response could be life-saving.

Reducing the risk of heart attacks begins with adopting a healthier lifestyle. Here are some suggestions to help you stay heart-healthy:
