What causes feelings of heart discomfort and shortness of breath?

Generally, feelings of heart discomfort and shortness of breath may be related to poor air circulation, excessive fatigue, hypertension, asthma, or coronary atherosclerotic heart disease, among other causes, and require targeted management. It is recommended to seek timely medical evaluation and treatment at a hospital. Specific details are as follows:

1. Poor Air Circulation

When harmful gases, smoke, or other pollutants are present in the air, the respiratory system cannot obtain sufficient oxygen, leading to decreased oxygen levels in the blood. This forces the heart to work harder to meet the body's oxygen demands, potentially causing heart discomfort and shortness of breath. It is advisable to open windows and maintain good indoor ventilation.

2. Excessive Fatigue

During periods of excessive fatigue, the body requires more oxygen and energy to support muscle and cardiac activity. If the heart cannot meet these increased demands, symptoms such as heart discomfort and shortness of breath may occur. Adequate rest should be taken, and overexertion that places strain on the body should be avoided.

3. Hypertension

Hypertension can overload the heart, increasing its workload and potentially impairing heart function over time, resulting in heart discomfort and shortness of breath. Hypertension may also present with symptoms such as headache, dizziness, and tinnitus; in severe cases, it may lead to cardiovascular symptoms including chest pain, palpitations, and nausea. It is recommended to follow medical advice and use medications such as nifedipine tablets, methyldopa tablets, or captopril sustained-release tablets to manage the condition.

4. Asthma

Asthma is a chronic respiratory disease characterized by airway narrowing, which impairs gas exchange and leads to breathing difficulties, often resulting in shortness of breath and heart discomfort. During an asthma attack, respiratory symptoms such as wheezing, coughing, and chest tightness may occur, along with cardiovascular symptoms like palpitations or rapid heartbeat. Under medical guidance, medications such as compound aminophylline tablets, dyphylline tablets, or doxofylline tablets may be used to relieve symptoms.

5. Coronary Atherosclerotic Heart Disease

Coronary atherosclerotic heart disease occurs when atherosclerotic plaques in the coronary arteries cause narrowing or blockage, reducing blood supply to the heart. This may lead to angina and myocardial ischemia, causing heart discomfort and shortness of breath. Treatment may include medications such as clopidogrel hydrogen sulfate tablets, ticagrelor tablets, or simvastatin dispersible tablets, as recommended by a physician.

In daily life, maintaining a balanced diet and engaging in moderate physical activity are beneficial for overall health.
