Patient: coronary heart disease-acute myocardial infarction, acute heart failure attack, chest pain, dyspnea, unable to lie flat, how to treat it?

I have met similar patients in clinic. The patient received aspirin, clopidogrel antiplatelet therapy and low molecular weight heparin anticoagulation therapy, furosemide and nitroglycerin were given intravenously, and recombinant human brain natriuretic peptide (bioactive peptide) was also given. Start loading 1.5ug/kg, and inject intravenously for 5 minutes, then continue intravenous drip at the rate of 0.0 1ug/kg/min. After 1 hour, the patient's dyspnea was relieved, the respiratory frequency dropped to 28 beats/minute, the heart rate dropped to 103 beats/minute, and the pulse oxygen saturation rose to 92%. After 3 hours, the patient's dyspnea was obviously relieved, the respiratory rate dropped to 24 beats/min, the heart rate dropped to 95 beats/min, the bleb sound in both lungs decreased, and the pulse oxygen saturation rose to 95%. The respiratory rate dropped to 20 beats/min, the heart rate dropped to 84 beats/min, the bleb sounds in both lungs dropped significantly, and the pulse oxygen saturation rose to 97%. After 24 hours of treatment, the patient could basically lie on his back without obvious dyspnea, the respiratory rate dropped to 65438 09 beats/min, the heart rate dropped to 865438 0 beats/min, and a small amount of bleb sounds could be heard at the bottom of both lungs.
