Heart disease remains the leading cause of death in the United States, killing someone every 33 seconds, yet many people don’t realize they are at risk until it’s too late. While chest pain and shortness of breath are well-known symptoms of a heart attack, there are subtle, silent signs that could indicate an increased risk of heart disease—often long before a heart attack occurs. Identifying these signs early and seeing your primary care provider for regular check-ups can make all the difference.
What is Heart Disease?
Heart disease is an umbrella term for conditions that affect the heart, including coronary artery disease (CAD), arrhythmias, and heart failure. The most common type, CAD, occurs when plaque builds up in the arteries, narrowing blood flow and increasing the risk of heart attack or stroke. Many risk factors for heart disease develop gradually and without noticeable symptoms, making preventive care essential.
7 Silent Signs That May Indicate Heart Disease
1. High Blood Pressure: The “Silent Killer”
High blood pressure (hypertension) is often called the silent killer because it typically has no symptoms. Over time, uncontrolled high blood pressure can damage arteries, increasing the risk of heart attack, stroke, and heart failure.
Why It Matters: Many people don’t know they have high blood pressure until it’s measured at a routine doctor’s visit. Regular check-ups with your primary care provider can help monitor and manage blood pressure before it leads to serious complications.

2. High Cholesterol: No Symptoms, Big Impact
Like high blood pressure, high cholesterol often has no obvious symptoms but can quietly contribute to plaque buildup in the arteries. Over time, this can lead to a heart attack or stroke. A simple blood test is the only way to detect high cholesterol levels.
Why It Matters: The good news? Lifestyle changes and, if necessary, medications can lower cholesterol levels and reduce cardiovascular risk. A primary care provider can assess your levels and recommend the best approach to keeping your heart healthy.

3. Fatigue and Sleep Disturbances
Feeling exhausted despite getting a full night’s sleep? Persistent fatigue, particularly in women, may be an early warning sign of heart disease. Sleep apnea, a condition where breathing repeatedly stops and starts during sleep, is also linked to a higher risk of high blood pressure, heart attack, and stroke.
Why It Matters: If you experience extreme fatigue, frequent waking at night, or loud snoring, talk to your doctor about a sleep study to assess your risk for sleep apnea and other underlying conditions.

4. Erectile Dysfunction (ED) in Men
Many men don’t realize that erectile dysfunction (ED) can be an early sign of heart disease. ED is often caused by reduced blood flow due to narrowed arteries—a potential warning of cardiovascular issues.
Why It Matters: If you’re experiencing persistent ED, consider it a wake-up call to check in with your doctor about your heart health.

5. Swelling in the Legs and Feet
Swollen ankles, feet, or legs can be a sign of poor circulation or heart failure. When the heart isn’t pumping effectively, fluid can accumulate in the lower extremities.
Why It Matters: Occasional swelling can be due to lifestyle factors like prolonged sitting or high salt intake, but persistent swelling should be evaluated by a doctor.

6. Gum Disease and Oral Health Issues
Believe it or not, your oral health can provide clues about your heart health. Studies suggest that gum disease (periodontitis) is linked to an increased risk of heart disease, possibly due to inflammation and bacteria affecting the cardiovascular system.
Why It Matters: Regular dental check-ups and good oral hygiene aren’t just for your teeth—they may also protect your heart.

7. Obesity and Waist Circumference
Carrying extra weight, especially around the abdomen, significantly increases the risk of heart disease. Excess belly fat is linked to high blood pressure, high cholesterol, and insulin resistance—all of which contribute to heart disease.
Why It Matters: Even a 5-10% reduction in body weight can improve heart health. Your primary care provider can help you develop a personalized plan for weight management.

Why Regular Check-Ups Matter
Many of these silent signs are only detected through routine screenings with your primary care provider. During an annual wellness exam, your doctor can:
- Check your blood pressure, cholesterol, and blood sugar levels
- Assess your BMI and waist circumference
- Discuss any unusual symptoms, even if they seem minor
- Recommend lifestyle changes or medications to reduce your risk
