Whether cardiomyopathy poses a threat to life depends on the severity of the condition. Mild myocardial damage, if detected early, diagnosed early, and treated with effective medications in a timely manner, generally has a good prognosis, poses no threat to life, and leaves no sequelae. Severe myocardial damage, due to lack of timely treatment, can lead to serious complications such as heart failure, arrhythmias, and cardiogenic shock, which can endanger life safety. Therefore, early diagnosis, early treatment, and prevention of complications are crucial treatment measures for cardiomyopathy.
