While asthma is one of the most common chronic diseases, cardiovascular disease is the leading cause of death worldwide. Therefore, understanding the relationship between the two diseases has great significance in the care and treatment of asthma and cardiovascular disease.

Cardiac asthma is not a normal type of asthma, but is caused by heart failure and other conditions that impair the heart's function. As the disease gets worse, fluid builds up, making it harder for the heart to pump blood effectively and the airways become narrow.

Cardiac asthma is not a common asthma and if not differentiated from bronchial asthma, incorrect treatment will cause serious consequences for the patient's health. Therefore, patients need to clearly and accurately distinguish between bronchial asthma and cardiac asthma to have the correct treatment direction.
