The symptoms of coughing with heart pain are clinically considered acute upper respiratory tract infection, where the inflammatory response is strong and continues to be severe with complications, manifesting as damage to cardiomyocytes and even leading to the occurrence of myocarditis. Due to the invasion of viruses, bacteria and other pathogens in the upper respiratory tract infection, the mucosa becomes severely inflamed, and the gradual aggravation of inflammation can involve the cardiomyocytes of the heart, resulting in different degrees of toxicity, ischemia and hypoxia, leading to their damage and even myocarditis.
