Recognizing the physical signs of a heart attack, also known as a myocardial infarction (MI), is crucial for prompt medical attention and potentially life-saving intervention. While symptoms can vary from person to person and between men and women, there are several common indicators to be aware of.
Chest discomfort or pain is often the most prominent symptom of a heart attack. This discomfort may feel like pressure, squeezing, fullness, or pain in the center or left side of the chest. It can last for a few minutes or come and go.
Pain or discomfort in other areas of the upper body can also signal a heart attack. This may include pain or discomfort in one or both arms, the back, neck, jaw, or stomach.
Shortness of breath is another common symptom. It may occur with or without chest discomfort and can happen before or during chest discomfort.
Other signs and symptoms that may indicate a heart attack include:
- Nausea or vomiting
- Lightheadedness or dizziness
- Breaking out in a cold sweat
- Fatigue
- Feeling of impending doom
It’s important to note that women may experience different symptoms than men. Women are more likely to have shortness of breath, nausea, vomiting, and back or jaw pain. They may also experience chest pain or discomfort that is less severe or more like pressure than the typical chest pain experienced by men.
In some cases, people may have a “silent” heart attack, where they experience no symptoms at all or symptoms are so mild that they go unnoticed. This is more common in older adults and people with diabetes.
Recognizing the signs of a heart attack and seeking immediate medical attention can significantly improve the chances of survival and minimize damage to the heart muscle. If you or someone else is experiencing symptoms that could indicate a heart attack, it’s essential to call emergency services or go to the nearest emergency room without delay.

In addition to the common physical signs and symptoms of a heart attack, it’s valuable to understand the underlying mechanisms and risk factors associated with this cardiovascular event.
A heart attack occurs when the blood flow to a part of the heart muscle is blocked for an extended period, usually due to the obstruction of one or more coronary arteries. The blockage is typically caused by the buildup of plaque—a combination of cholesterol, fat, and other substances—inside the arteries, a condition known as atherosclerosis. When a plaque ruptures, a blood clot can form and block the flow of blood to the heart muscle, leading to a heart attack.
Several factors can increase the risk of developing atherosclerosis and experiencing a heart attack. These risk factors can be divided into modifiable and non-modifiable categories:
Non-modifiable risk factors include:
- Age: The risk of heart attack increases with age, especially after 65 for men and 55 for women.
- Gender: Men are at a higher risk of heart attack than premenopausal women, although the risk for women increases after menopause.
- Family history: A family history of heart disease, especially if a close relative developed heart disease at an early age, increases the risk.
- Ethnicity: Certain ethnic groups, such as African Americans, Hispanic Americans, and South Asians, have a higher risk of heart disease.
Modifiable risk factors include:
- High blood pressure (hypertension)
- High cholesterol levels, particularly high levels of LDL cholesterol (“bad” cholesterol) and low levels of HDL cholesterol (“good” cholesterol)
- Smoking
- Diabetes mellitus
- Obesity and overweight
- Physical inactivity and sedentary lifestyle
- Unhealthy diet, particularly one high in saturated and trans fats, cholesterol, and sodium
Managing modifiable risk factors through lifestyle changes and, when necessary, medication, can significantly reduce the risk of developing atherosclerosis and experiencing a heart attack. Lifestyle modifications include adopting a heart-healthy diet rich in fruits, vegetables, whole grains, and lean proteins, engaging in regular physical activity, maintaining a healthy weight, quitting smoking, and managing stress.
In addition to lifestyle changes, healthcare providers may prescribe medications to control blood pressure, cholesterol levels, and blood sugar levels in individuals with hypertension, dyslipidemia, or diabetes. In some cases, antiplatelet medications, such as aspirin, and anticoagulants may be recommended to reduce the risk of blood clot formation.
Furthermore, for individuals at high risk of heart attack due to factors such as a history of previous heart disease or certain medical conditions, healthcare providers may recommend additional interventions, such as coronary artery bypass surgery or percutaneous coronary intervention (angioplasty and stenting), to improve blood flow to the heart.
Regular medical check-ups, including screenings for risk factors and early signs of cardiovascular disease, are essential for maintaining heart health and preventing heart attacks. By understanding the signs, symptoms, risk factors, and preventive measures associated with heart attacks, individuals can take proactive steps to protect their cardiovascular health and reduce the likelihood of experiencing a life-threatening cardiac event.
