Every year, heart disease claims up to 18 million lives worldwide, across all age groups. A significant portion of these deaths could be prevented with early detection and timely medical intervention.
Unfortunately, identifying heart issues is not always straightforward. Heart problems often mimic mild discomfort or normal bodily sensations. Here’s a list of subtle symptoms that may indicate underlying heart conditions.
Attention! People over 60, as well as those with excess weight, diabetes, hypertension, or high cholesterol levels, should be especially vigilant.
1. Chest Discomfort
According to experts at WebMD, chest discomfort is the most common indication of heart problems.
The sensation can be hard to describe—some experience mild pain, others feel pressure or tightness, while some report burning or tingling. If you notice unusual sensations in your chest from time to time, promptly consult a healthcare professional for an electrocardiogram (ECG) and heart ultrasound.
These symptoms often signal issues with the blood vessels supplying the heart or an impending heart attack.
If the pain is intense and lasts more than a few minutes, call emergency services immediately.
On a positive note, 80–90% of chest pain cases are not heart-related, but medical evaluation is crucial to be certain.
2. Loss of Appetite, Nausea, or Stomach Discomfort
Digestive issues can arise from many causes unrelated to the heart. However, sometimes reduced blood flow to the digestive system, due to heart problems, triggers these symptoms.
If you experience unexplained nausea, especially alongside chest discomfort or other symptoms on this list, see a doctor without delay.
3. Pain Radiating to the Left Arm
Nerves from the heart and the left arm converge in the same brain region, causing the brain to sometimes misinterpret the source of pain.
If you’ve recently strained or injured your left arm, discomfort is expected. However, severe pain in the left arm without an obvious cause is a classic heart attack symptom.
The American Heart Association advises calling emergency services if sudden left arm pain persists or worsens within minutes.
If the pain is brief but familiar, schedule a medical consultation promptly.
4. Tooth or Lower Jaw Pain
This is another example where the brain struggles to pinpoint whether the heart or jaw is the pain source. Usually, dental or jaw pain results from cavities, muscle strain, or cold drafts. But if unexplained, persistent toothaches occur, a cardiology evaluation is warranted.
There have been clinical cases where patients underwent multiple tooth extractions before the true cardiac cause was identified.
5. Brief Dizziness or Disorientation
Temporary weakness can be caused by many factors, such as hunger or standing up too quickly after sitting.
However, recurrent dizziness suggests the heart may not be pumping enough blood to the brain, potentially signaling an impending stroke.
6. Persistent Fatigue
A weakened heart cannot maintain adequate blood circulation. As a result, organs and tissues receive less oxygen and nutrients. The body prioritizes vital organs like the heart, brain, and lungs, reducing blood flow to limbs.
Everyday activities like showering, washing dishes, or climbing stairs become exhausting, and rest fails to restore energy.
If you’ve experienced this for several days or longer, consult a cardiologist to rule out worsening heart conditions.
7. Swelling in the Legs
Poor circulation affects lymphatic drainage, causing fluid to accumulate under the skin, especially in the legs, leading to swelling.
If leg swelling is persistent, seek advice from a healthcare provider.
8. Prolonged Cough
Coughing is common with colds, but if it persists weeks after recovery, medical evaluation is essential.
While allergies or bronchitis may cause ongoing cough, heart failure can also lead to fluid buildup in the lungs, triggering a persistent cough.
A key sign of heart-related cough is the presence of pink or white mucus. If you notice this, consult a cardiologist immediately.
9. Unexplained Shortness of Breath
Shortness of breath usually occurs with physical exertion as muscles demand more oxygen.
Other causes include obesity, sedentary lifestyle, stress, or stuffy environments.
However, if shortness of breath occurs without apparent reason and is accompanied by fatigue, chest discomfort, or other symptoms listed here, it’s time to see a cardiologist.
This may indicate reduced oxygen levels caused by impaired heart function.
10. Loud Snoring
Snoring during sleep is common, but very loud snoring may indicate sleep apnea—a temporary cessation of breathing during sleep.
Sleep apnea damages the cardiovascular system by causing oxygen deprivation to the heart muscle and increasing the risk of hypertension, which strains the heart further.
Treating sleep apnea is crucial. Start by consulting your primary care physician.
11. Rapid or Irregular Heartbeat
Feeling your heart race is normal during excitement or intense exercise.
However, if your heart races or skips beats without cause, this signals a problem requiring immediate medical attention.
