The diseases with the highest incidence among the elderly are cardiovascular diseases, including hypertension, cerebral infarction, cerebral hemorrhage, angina pectoris and myocardial infarction. Therefore, elderly people should always have emergency drugs for these diseases at home, including antihypertensive drugs, vasodilators and antithrombotic drugs. The main antihypertensive drugs are short-acting antihypertensive drugs such as nicorandipine and captopril, which are fast-acting, but they are not stable and should not be taken for a long time, otherwise they are likely to cause cardiovascular accidents. The main vasodilator drugs include nitroglycerin, isosorbide nitrate and compound danshen drops, which can quickly relieve chest pain, chest tightness and other angina symptoms. Antithrombotic drugs include aspirin, clopidogrel sulfate tablets, statin and other drugs, which can be used to rescue acute cerebral infarction and acute coronary syndrome, thus buying valuable time for going to hospital for treatment.
