If the patient suddenly develops heart pain, sublingual nitroglycerin or compound salvia drops can be given to help stop the onset of pain. In addition, it is advisable to measure the heart rate and blood pressure. If the blood pressure is lower than before, it is advisable to go to the emergency department for an electrocardiogram to see if an acute right ventricular myocardial infarction has occurred. If the current blood pressure is not low and the heart rate is fast, oral bisoprolol or propranolol can be taken, which can help improve the current painful symptoms. Patients are also advised to take drugs such as aspirin, which is mainly anti-atherosclerotic and anti-platelet. If no relief is seen after medication, it is still recommended to go to the emergency department for further diagnostic treatment.
