What are "signs" and "signals" before onset of heart disease?

Heart disease is a common disease of circulatory system. The circulatory system consists of heart, blood vessels and neurohumoral tissues that regulate blood circulation. Diseases of circulatory system are also called cardiovascular diseases.

Epidemiological studies have shown that morbidity and mortality from cardiovascular diseases continue to rise, and coronary heart disease is gradually becoming most common heart disease. Mortality is still very high.

So, in everyday life it is very important to prevent occurrence of heart disease. But if heart disease has already appeared, it is very important to achieve early detection, early diagnosis and early treatment, and is also critical for prognosis!

“Early detection” is first and most important step here. So, what are "signs" and "warning signs" in early stages of heart disease?

1. Sleep Apnea

If snoring is interrupted by pauses in breathing, brain may not have enough oxygen. It signals your blood vessels and heart to work harder to keep blood flowing. This increases risk of high blood pressure, cardiac arrhythmias, stroke, and heart failure. Fortunately, sleep apnea is treatable.

2. Poor grip strength

The strength of your hands can tell you something about strength of your heart. Studies show that "the ability to squeeze out useful things" means a lower risk of heart disease. If you have difficulty grasping an object, you are more likely to have a problem, or may have a problem. (But improving grip strength alone won't necessarily make your heart healthier.)

3. Ecchymosis

If you haven't bruised or injured your fingers or toes recently, small spots of blood under your nails could indicate an infection in lining of your heart or valves, called endocarditis. You can also get these blood spots when you have diabetes, and people with condition are two to four times more likely to have heart attacks and strokes.

4. Dizziness

Dizziness is often a direct result of heart problems because it doesn't supply enough blood to brain. Dizziness can be a symptom of an abnormal rhythm called an arrhythmia. Heart failure, which means weakened muscles, can also make you unbalanced. Feeling dizzy is also one of many lesser known symptoms of a heart attack.

5, Problem X

A little trouble in bedroom could mean you have heart disease and an increased risk of a heart attack or stroke. Men with erectile dysfunction may have circulatory problems associated with narrowing of arteries caused by high blood pressure or high cholesterol levels. These blood flow problems can also decrease a woman's libido and her ability to enjoy sex.

6. Skin color changes

Blue or gray fingers and toes can be caused by poor circulation due to lack of oxygen, usually because you were born with a heart defect or narrowed or clogged blood vessels. A lacy, mottled, purple pattern appears when some of accumulated cholesterol plaques break off and then get stuck in small blood vessels. With endocarditis, you may develop blood spots under skin on your hands and soles.

7. Bleeding gums

Experts don't fully understand link between gum disease and heart disease. But research shows that bleeding, swollen, or soft gums can cause problems. One theory is that bacteria from your gums enters your bloodstream and causes inflammation in your heart. Gum disease, which can lead to tooth loss, can also increase your chances of having a stroke.

8. Shortness of breath

Feeling short of breath can be a symptom of heart failure, an abnormal heart rhythm, or a heart attack. Tell your doctor if you have trouble breathing, if you are doing something that used to be easy for you, or if you find it difficult to breathe while lying down. Do you also have chest pains? Do not forget to consult a doctor in time.

9. Swelling of lower extremities

This happens when you stand or sit for long periods of time, and also during pregnancy. Fluid buildup can also be associated with heart failure and poor circulation in legs. Leg swelling can be caused by a blood clot that blocks return of blood from lower extremities to heart. In case of sudden swelling, contact your doctor immediately.

10. Fatigue

Don't always blame sleep deprivation. Heart failure can make you tired and exhausted because your muscles can no longer pump enough energy to meet your body's needs. Pay attention to other symptoms such as coughing and swelling because feeling weak and weak can be a warning sign for many different illnesses, including anemia, cancer, and even depression.


There are many "hidden" clues before heart disease occurs, including sleep apnea, subcutaneous ecchymosis, poor grip strength, dizziness, X dysfunction, swelling of lower extremities, bleeding gums, etc. We should always pay attention to our physical and mental changes, especially for people with poor heart function and a relevant family history, are critical for early prevention, early detection, early diagnosis and early treatment!
