Shortness of breath, also known as dyspnea, is a feeling of having difficulty breathing. This can occur both during physical activity and at rest. There are many possible causes, ranging from heart failure to asthma or chronic obstructive pulmonary disease (COPD).

Chest pain

Chest pain or discomfort may be related to the heart, but also to other parts of the body, such as the stomach or muscles. It is important to distinguish between the different types of pain in order to identify the possible cause.

Typical symptoms of cardiopulmonary disease

Shortness of breath (Dyspnea): A feeling of difficulty breathing, which can occur during physical activity, at rest, or both.
Chest pain: Pain or discomfort in the chest area can be a sign of heart problems such as angina or a heart attack, but can also be caused by other factors such as muscle tension or digestive problems.
Cough: A persistent cough, especially one that produces white or pink frothy mucus, may be a sign of heart failure. Coughing can also be related to the lungs, such as with bronchitis or pneumonia.
Wheezing: A wheezing sound when breathing can indicate a narrowing or blockage in the lungs.
Swollen legs and feet (Edema): Accumulation of fluid in the legs and feet may be a sign of heart failure.
Fatigue: Overwhelming fatigue or weakness can be a sign of heart problems or lung diseases.
Irregular heartbeat (arrhythmia): An irregular heartbeat can feel like a fluttering in the chest or as if the heart is skipping beats.
Pale or bluish skin: This may be a sign of low blood oxygen levels, which can be caused by heart or lung problems.
Dizziness or fainting: This may be related to heart problems, low blood pressure, or other causes.

Cough and wheezing

A persistent cough or wheezing may be a sign of lung disease. It can also be a symptom of heart failure, especially if accompanied by other symptoms such as shortness of breath or fatigue.

Swollen legs and feet

Fluid retention, also known as edema, can cause swelling, especially in the legs and feet. This can be a sign of heart failure or other heart conditions.

Fatigue and weakness

The feeling of constant fatigue, even after a good night's sleep, can be a symptom of heart problems. It is important to listen to your body and seek medical attention if the fatigue persists.
