Heart disease is a rather general term that includes a variety of diseases, such as acute heart failure, acute angina pectoris, acute myocardial infarction, and a variety of cardiac arrhythmias. When an acute attack occurs, self-help methods vary and oral medications vary, and mastering certain methods can improve survival rates. Those with acute heart failure may manifest as: sudden onset of dyspnea, cyanosis, fast breathing, profuse sweating, irritability, and even coughing up frothy sputum. Self-treatment is as follows: try to maintain a quiet state, avoid irritability, take a semi-recumbent or sitting position with legs down to reduce venous reflux, and oxygen can be administered if oxygen is available. Acute angina pectoris and acute myocardial infarction attack can be manifested as pain in the precordial region and pain behind the sternum, which lasts for different periods of time and can be accompanied by heavy sweating, chest tightness and difficulty in breathing. At this time, you should immediately rest in bed, eliminate tension, maintain a quiet state, sublingual nitroglycerin or oral quick-acting heart pills 10-15, aspirin 300mg chew. In the case of arrhythmia, it is mostly seen in ventricular premature beats, atrial premature beats or atrial fibrillation, which can be manifested as accelerated heart rate and chest tightness during the attack. To keep quiet, take oral beta receptor antagonist such as metoprolol, or heart stabilizing granules, and add aspirin to anticoagulate. After the above treatment, call 120 and send to hospital in time to avoid shouting and screaming, which may aggravate the attack.
