When myocardial ischemia occurs in a 27-year-old young man, we first need to look for the causative factors leading to myocardial ischemia, such as hypertension, hyperlipidemia, poor diet and lifestyle habits, and other causative factors. If there is hypertension, we first lower the blood pressure to normal through non-pharmacological treatment, and if it is not properly controlled, then give antihypertensive drugs for antihypertensive treatment. If the usual diet is inclined to fatty and greasy resulting in high blood lipids, causing myocardial ischemia, it is necessary to lower the lipids through statin drugs, thus improving the vascular condition. Usually, you can take Chinese patent preparations, such as heart daikang, heart stabilizing granules, etc. You can also choose drugs such as isosorbide mononitrate tablets to improve the condition of myocardial ischemia.
