Heart disease is a group of heart conditions that negatively affect the structure or function of the heart and blood vessels. Recognizing the presence of heart disease can be difficult because there are often no early, noticeable symptoms.
However, heart disease can lead to serious heart problems (including sudden cardiac arrest), so it’s a good idea to familiarize yourself with the different warning signs it's associated with. Keep reading to discover the signs of heart disease to look out for—and be sure to speak with your healthcare provider if you believe you may have heart disease or are at risk.
Take the at-home Heart Health Test to measure indicators of cholesterol, blood sugar, and inflammation—all of which play key roles in heart disease risk.
Because of the vital role the heart plays in overall health and well-being, be sure to speak with your healthcare provider as soon as possible if you believe you may have any of the heart disease warning signs below.
Having high blood sugar over the long-term is a major risk factor for the development of the most common type of heart disease, coronary artery disease (also called coronary heart disease). That’s because consistently elevated blood sugar levels can eventually harm blood vessels as well as the system of nerves that help regulate heart function. This is one reason why diabetes is associated with an increased risk of heart disease.
High blood pressure, or hypertension, means that blood flows through the arteries with more force, which can hurt artery walls over time. Studies show that high blood pressure is a key risk factor for coronary heart disease, stroke, heart valve diseases, and aortic syndromes (the aorta is the body’s largest artery).
High levels of LDL cholesterol (also known as “bad cholesterol”) can directly contribute to the development of heart disease by promoting plaque buildup on artery walls. This, in turn, can cause the arteries to harden (atherosclerosis) and restrict the easy flow of blood—potentially leading to heart disease, heart attack, or stroke.
To check in on your cholesterol levels from the convenience of home, try the Everlywell at-home Cholesterol & Lipids Test.
If you have heart disease, you may experience any of the following physical symptoms. Do note that symptoms of cardiovascular disease can manifest differently from one person to the next, shaped by factors like one’s biological sex.
Chest pain or chest discomfort that occurs when blood does not flow freely through the blood vessels of the heart is called angina. The discomfort in your chest may feel like a squeezing or burning sensation. You may also feel tightness going into other parts of your upper body, such as your arms, neck, jaw, and back. Chest pain can happen during physical activity, such as lifting heavy objects or climbing stairs.
Angina is one of the most common heart problem symptoms and is the most common heart attack warning sign in men as well as women. Other common heart attack symptoms include shortness of breath, nausea, vomiting, jaw pain, and back pain.
Seek emergency medical treatment immediately by calling 9-1-1 if you or someone you know is experiencing heart attack warning signs.
One of the possible symptoms of heart disease is shortness of breath. This can happen both when you’re resting and while you’re engaged in activity. When related to heart health, shortness of breath can be either acute or chronic—also referred to as acute and chronic dyspnea:
If blood vessels are narrowed in the ankles, legs, and feet, it can cause an accumulation of fluid in tissues that cause swelling.
Some people with heart problems complain of a persistent cough. This is caused by fluid buildup in the lungs, known as pulmonary edema.
Fatigue caused by heart disease can make you feel suddenly weak and/or exhausted. You may feel so tired that you are unable to do normal daily activities.
An irregular heartbeat can make you feel like your heart is racing or throbbing. You may have this heart disease symptom if your heart is unable to pump blood properly and attempts to make up for it by beating faster.
Research has found a strong link between erectile dysfunction and heart disease. Approximately 50-60% of erectile dysfunction in men over the age of 60 is caused by atherosclerosis, the leading cause of coronary heart disease. Additionally, conditions that affect the blood vessels (collectively called vascular diseases) also impede erectile function. High blood cholesterol and high blood pressure are additional risk factors for erectile dysfunction. These heart or blood vessel conditions restrict blood flow to the genitals, causing erectile dysfunction.
Here’s a list of possible heart disease signs sorted by different types of heart disease.
Take the Everlywell Heart Health Test kit to easily discover your levels of cholesterol, blood sugar (via an HbA1c measurement), and inflammation (via hs-CRP testing). The test results—which you can securely access online—can help tell you whether you have key risk factors for heart disease.
