What medicine does heart failure take?

My uncle was diagnosed with coronary heart disease during his previous physical examination and has been taking medication to control it. Some time ago, he suddenly felt difficulty breathing and was admitted to the hospital. I went to the hospital to see him, and he told me that heart failure caused dyspnea. The doctor prescribed Qiliqiangxin Capsule, which was mainly used for heart failure caused by coronary heart disease, hypertension and other diseases. Its main components are pure Chinese medicinal preparations, such as Radix Astragali, Ginseng Radix, Heishun Tablet, Radix Salviae Miltiorrhizae, Semen Lepidii, Alismatis Rhizoma, Rhizoma Polygonati Odorati, Ramulus Cinnamomi, Carthami Flos, Cortex Periplocae, Pericarpium Citri Tangerinae, etc. In the formula, ginseng, astragalus root and aconite root can enhance the function of relaxation and contraction, while lepidium seed and Alisma orientale can eliminate edema. People with heart failure can be controlled by long-term use. My uncle went to see him after he was discharged from the hospital for a while, and his spirit seemed much better than before. He said there were few cases of dyspnea.
