Cardiorespiratory issues refer to problems with the heart and respiratory (breathing) system. Some examples of cardiorespiratory issues include:

• Heart conditions: These include conditions such as coronary artery disease, heart failure, and arrhythmias (irregular heart rhythms). Symptoms of heart conditions can include chest pain, shortness of breath, fatigue, and palpitations.

• Respiratory conditions: These include conditions such as asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. Symptoms of respiratory conditions can include coughing, wheezing, shortness of breath, and difficulty breathing.

• Cardiorespiratory arrest: This is a medical emergency in which the heart and lungs stop functioning properly. Symptoms of cardiorespiratory arrest include loss of consciousness, no pulse, and no breathing. This condition requires immediate medical attention.

Cardiorespiratory issues can range from mild to severe and can be caused by a variety of factors, including genetics, lifestyle, and environmental factors.

​

More common cardiorespiratory issues include:

• Coronary artery disease: This is a condition in which the arteries that supply blood to the heart muscle become narrowed or blocked due to the buildup of plaque. This can lead to chest pain (angina), shortness of breath, and an increased risk of heart attack.

• Heart failure: This is a condition in which the heart is unable to pump blood effectively. This can cause fluid to build up in the body, leading to symptoms such as shortness of breath, fatigue, and swelling in the legs and ankles.

• Arrhythmias (irregular heart rhythms): This refers to any abnormal heartbeat pattern. There are many different types of arrhythmias, and they can range from benign to potentially life-threatening. Symptoms can include palpitations (a sensation of the heart racing or skipping a beat), fainting, and chest pain.

• Heart attack: A heart attack occurs when the blood supply to the heart is blocked, causing damage to the heart muscle. Symptoms of a heart attack include chest pain, shortness of breath, and nausea.

• Heart valve problems: The heart has four valves that help to ensure that blood flows in the correct direction through the heart. Heart valve problems can occur when the valves become narrowed or leaky, leading to symptoms such as shortness of breath, fatigue, and swelling in the legs and ankles.

• Cardiomyopathy (disease of the heart muscle): This is a general term for a group of conditions that affect the heart muscle. Cardiomyopathy can cause the heart to become weak, enlarged, or stiff, leading to symptoms such as shortness of breath, fatigue, and swelling in the legs and ankles.

• Pulmonary embolism (blood clot in the lungs): A pulmonary embolism is a blood clot that has traveled to the lungs and blocked an artery. This can cause symptoms such as chest pain, shortness of breath, and a rapid heart rate.

• Chronic obstructive pulmonary disease (COPD): This is a group of lung conditions that cause breathing difficulties. COPD includes conditions such as emphysema and chronic bronchitis. Symptoms can include coughing, wheezing, and shortness of breath.

• Asthma: This is a chronic lung condition that causes the airways to become inflamed and narrow, leading to symptoms such as coughing, wheezing, and shortness of breath.

• Pneumonia: This is an infection of the lungs that can cause symptoms such as fever, cough, and difficulty breathing.

• Tuberculosis: This is a bacterial infection that primarily affects the lungs. Symptoms can include a persistent cough, fever, and weight loss.

• Bronchitis: This is an inflammation of the lining of the bronchial tubes, which carry air to and from the lungs. Symptoms can include a cough, chest congestion, and difficulty breathing.

• Emphysema: This is a lung condition that damages the air sacs in the lungs, leading to difficulty breathing.
