7Wheezing Noises
In moderate and mild cases of cardiac asthma, you can easily notice the wheezing and whistling noises when breathing out. However, this symptom would occur both on inhalation and exhalation in more advanced cases. These sounds are caused when the throat muscles around the upper or lower respiratory tract are constricted due to inflammation. Just like chest pain or tightness, this is also a very serious symptom that requires medical attention. Early detection can allow for better treatments and prevent some other conditions. [7]
