11 signs that could indicate a heart problem

You may have heard someone say that cardiovascular disease, or heart problems, is silent. But our bodies give signs, however subtle, that the health of our heart is in danger.

If you are in a risk group for an illness you already have, be sure to pay attention to the signs, no matter how small, and to have regular checkups.

Prevention and early diagnosis are the most important measures to avoid the consequences of heart problems that can, in many cases, be fatal.

According to the Brazilian Society of Cardiology, cardiovascular diseases, which affect the heart and circulation, are the leading cause of death in Brazil, more than all types of cancer combined, deaths from accidents and violence, respiratory diseases and infections.

Many of these cases can be prevented with simple preventive measures, and treated, if identified early. To do this, it is important to know the signs that indicate a probable heart problem.

See what signs may indicate that you are at risk for a heart problem.

Some groups of people need extra attention

Before you know the signs that indicate a heart problem, it’s important to know which groups of people are most at risk for developing these problems, so that attention and attention are redoubled:

Uncontrolled hypertension (high blood pressure)

High cholesterol

decompensated diabetes

overweight and obesity

Bad eating habits, with a very high fat and sugar diet.

Sedentary lifestyle

Family history of heart disease

Signs of heart problems

The first thing to keep in mind is that the signs of heart problems will not always be sudden or sudden. This is important to mention because we often associate heart problems with a heart attack.

In fact, a heart attack is a very serious type of heart problem and is characterized by sudden chest pain, shortness of breath, and fainting.

But the signs are not always so striking and sudden. Cardiovascular diseases develop over time and can be confused with everyday situations, such as poor fitness, snoring or fatigue.

Therefore, when you notice the following signs, be sure to look for a doctor and do routine examinations, as they can reverse serious situations.


Fatigue is defined as a feeling of extreme tiredness, tiredness and lack of energy.

It is natural for a person who leads a sedentary lifestyle to feel out of breath when he or she starts exercising. But over time, you will notice an improvement in your fitness and gradually you will feel less tired with this level and load of exercise.

What is not normal is to feel very tired when doing light daily activities, such as walking, crouching or cleaning the house. Feeling very tired when doing light activities that do not require much energy indicates that the heart is weak and unable to pump blood properly.

Fatigue is a very important sign and is one of the first symptoms of many heart problems, such as:

Heart failure

Acute myocardial infarction

cardiac ischemia

cardiac arrhythmia

diseases of the valves


It is important to be aware of extreme and constant fatigue

cold sweat

Cold sweat is a very common symptom, which can be present in times of anxiety, stress or hypoglycemia, by those who use insulin to control diabetes hyperglycemia.

However, cold sweats can also indicate a cardiovascular problem and indicate an acute myocardial infarction. Therefore, in the face of the frequent and constant presence of this symptom, seek a doctor to investigate the cause.

Chest pain and palpitations

These are the symptoms that usually cause people to worry more about a possible heart problem, as they are the most characteristic and easily recognized.

Chest pain may concentrate or radiate to the shoulders, arms, back, and abdomen.

Palpitations are a cardiac arrhythmia, that is, when the heart rate is no longer regular, it becomes very weak, strong (tachycardia), or irregular.

Neck and jaw pain

Pain in these regions does not appear to be related to the heart, but may indicate the presence of obstructions in the arteries, which can progress to a heart attack.

Clogging of the arteries can occur due to the accumulation of fat or blood clots as a result of the rupture of these arteries. With this, the heart stops receiving oxygen and nutrients, causing the death of its cells.

Depending on the affected artery and the duration of the infarction, the heart may stop working completely.

dizziness and fainting

A sudden feeling of dizziness or fainting may indicate a cardiovascular problem, which has led to a reduction in blood flow to the brain. These signs can occur moments before a person has a heart attack.

Light headed

Feeling constantly dizzy could be a sign of a heart problem

Bluish discoloration on fingertips or fingernails

The constant sensation of cold hands and feet, leading to fingertips and bluish nails, can be a sign of heart failure.

In heart failure, the heart cannot pump enough blood to irrigate all parts of the body, prioritizing vital organs and leaving the limbs less irrigated. This is why the hands and feet get colder than the rest of the body.

Swelling and pain in the legs

Due to the action of gravity, the legs, ankles and feet tend to become more swollen and painful when a person suffers from heart failure.

Because this problem causes fluid retention, the legs are the parts that suffer the most from swelling. It is also common for this symptom to be accompanied by difficulty breathing when the person lies down to sleep or does some physical activity.

Urinate several times during the night

Weakening of the myocardium, which is the heart muscle, is related to fluid retention. Therefore, if you need to get up more often than usual to urinate at night, it could be a symptom of heart failure.

night cough

Night cough is also a sign of heart failure because when fluid builds up in the lungs, coughing occurs as a natural reflex of the body. Frequent coughing and wheezing do not always mean lung disease or asthma.

Therefore, if you are coughing heavily and short of breath, you should see a cardiologist to check the health of your heart.

Obstructive sleep apnea

Obstructive sleep apnea is the difficulty in breathing during sleep, which causes the person to stop breathing for a few seconds at night, with breathing pauses of at least 10 seconds.

The drop in oxygen levels in the blood is interpreted by the body as a warning signal, which causes the constriction of blood vessels, so that the blood circulates faster, so as not to leave the brain and heart without oxygen. . Elevated blood pressure is a major risk factor for cardiovascular problems.

Nausea, loss of appetite and stomach ache

These are not only symptoms of digestive problems, they can also indicate heart problems.

Changes in the anatomy of the heart that impair the proper functioning of the right side of the organ can cause symptoms of nausea and loss of appetite. In addition, problems with the arteries that supply blood to the lungs can also cause these symptoms.

Heart failure can also cause fluid to build up. When this retention occurs around the abdominal organs, it can cause digestive problems, which manifest themselves in stomach pain or in an enlarged liver.

Prevention of heart problems

It is important to keep in mind that preventing heart problems is not a complicated task as it basically involves cultivating healthy habits and doing regular checkups.

Knowing the signs that indicate a heart problem is very important for you to seek medical help at the beginning of the problem, as this increases the chances of the treatment being effective and avoids serious complications, which can be fatal.

So remember, daily:

Eat healthy, avoiding excess fat and sugar and increasing your intake of healthy protein, vegetables and fruits.

Exercise regularly, with aerobic and resistance exercises (weight training).

Practice activities to help relieve stress and anxiety.

Schedule an annual review with heart tests.
