Patients with myocardial ischemia taking compound salvia tablets have some effect in relieving the symptoms of angina pectoris, but they usually treat the symptoms but not the root cause. It can not solve the problem of myocardial ischemia at root, and it needs to be treated by regular secondary prevention of coronary heart disease and reperfusion therapy. It is suitable for people with chest tightness, precordial stabbing pain, angina pectoris, insufficient blood supply to the myocardium caused by coronary artery stenosis or occlusion, and myocardial infarction. However, some patients with myocardial ischemia may experience nausea or epigastric discomfort after taking Danshin Tablets orally, and some patients may also experience dizziness and other symptoms, but there is no need to worry too much, as they will gradually improve after stopping the drug without special treatment. If the patient has frequent episodes of symptoms or if the drug is ineffective, it is considered possible that severe coronary stenosis or even coronary occlusion has occurred, which is very serious and requires timely access to the hospital for further regular treatment, such as drug thrombolytic therapy and interventional stenting.
