The heart, a vital engine of the human body, keeps us alive by pumping blood throughout our system.

Like any engine, it can experience problems, and knowing the early warning signs of heart trouble can make a significant difference in managing health outcomes.

This review outlines the key indicators that suggest a heart may not be functioning properly, explaining them in plain language to help non-scientists recognize when it might be time to seek medical advice.

 Chest Discomfort or Pain One of the most well-known signs of heart trouble is chest pain or discomfort, often referred to as angina. This sensation can feel like pressure, squeezing, fullness, or pain in the center of the chest.

It occurs when the heart muscle doesn’t get enough oxygen-rich blood, and it can vary in intensity. Research has shown that people often ignore this symptom, especially when it doesn’t fit the dramatic depictions seen in movies.

However, any recurring chest pain, particularly if it occurs during physical activity and subsides with rest, should be evaluated by a healthcare provider.

Shortness of Breath Another significant sign is shortness of breath, which can occur when the heart struggles to pump blood to meet the body’s needs. This symptom might manifest itself not only during physical activity but also while resting or lying down.

Heart failure, a condition where the heart’s pumping efficiency is reduced, often leads to breathing difficulties.

Studies suggest that people experiencing this symptom, particularly in conjunction with other symptoms like fatigue or chest discomfort, should seek medical evaluation promptly.

Excessive Fatigue Feeling unusually tired can be a subtle and easily overlooked sign of heart disease. When the heart is less able to pump blood, other organs may not receive enough oxygen, leading to fatigue.

According to a study published in the Journal of the American Heart Association, women are more likely than men to experience fatigue as an early sign of heart disease.

If fatigue is persistent and cannot be explained by lack of sleep or physical exertion, it’s advisable to consult a healthcare professional.

Swelling in Legs, Ankles, and Feet Swelling in the lower parts of the body can indicate that the heart is not pumping blood effectively. When the heart’s pumping action is weakened, fluid from the blood can leak into surrounding tissues, a condition known as peripheral edema.

The retention of fluid is a common symptom of heart failure, and if accompanied by other symptoms like fatigue and shortness of breath, immediate medical attention is needed.

Irregular Heartbeat An irregular heartbeat or arrhythmia can feel like a racing heart or fluttering.

While it’s common to experience occasional heart palpitations, a persistent or severe arrhythmia can be a sign of an underlying heart condition, especially when combined with dizziness, fainting, or chest discomfort.

Continuous irregular heartbeats should be evaluated, especially if they are new or different, as they can lead to more serious conditions if not treated.

Dizziness or Lightheadedness Feeling dizzy or lightheaded frequently can be a sign of many conditions, including heart issues. It can occur if the heart is not able to pump enough blood to the brain due to a blockage or a failing heart valve.

These symptoms require attention, especially if they occur suddenly and are accompanied by chest pain or shortness of breath.


Recognizing the signs of an unhealthy heart is crucial for early intervention and effective management.

Symptoms like chest pain, shortness of breath, excessive fatigue, swelling in the lower extremities, irregular heartbeats, and frequent dizziness or lightheadedness are key indicators that should not be ignored.

Regular check-ups and discussing these symptoms with a healthcare provider can lead to early detection and treatment, significantly improving the quality of life and outcomes for individuals with heart conditions.
