How long a patient can live with myocardial ischemia at the age of 30 varies from person to person, and is closely related to the cause, treatment and complications. Patients diagnosed with myocardial ischemia at the age of 30 can mostly survive for a long time if they take medications or implant a coronary stent in strict compliance with medical advice, while exercising moderately and regulating the causative factors, and myocardial ischemia will hardly affect the survival of patients. If patients with myocardial ischemia at the age of 30 do not undergo standardized treatment and are combined with serious complications such as heart failure, the survival period of such patients is mostly shorter and may lead to sudden death at any time due to myocardial infarction or malignant arrhythmia. Therefore, the survival period of each patient with myocardial ischemia varies. In conclusion, patients with myocardial ischemia must go to the cardiology department of the hospital for standardized treatment in a timely manner, pay attention to rest, eat a light diet, and quit smoking and drinking.
