Nausea in patients with heart failure can be treated with diuretics, RASS antagonists, and beta-blockers. Clinical symptoms of nausea in patients with heart failure are usually caused by dysfunction of the right heart, resulting in gastrointestinal and hepatic stasis, which is the most common symptom of right heart failure. This is the most common symptom of right heart failure. Usually, diuretics can be chosen, such as furosemide and spironolactone, which can excrete sodium and drain water, thus reducing the volume load of the heart and improving cardiac function to relieve nausea; however, after taking the drugs, electrolytes need to be monitored to avoid electrolyte disorders. Secondly, you can choose captopril, chlorosartan, aldosterone and other RASS antagonists; after taking them, they can effectively dilate blood vessels and inhibit ventricular remodeling, thus improving cardiac function and relieving nausea and other uncomfortable symptoms. But for angioedema, anuric renal failure is prohibited. Beta-blockers are common drugs such as metoprolol, which can inhibit the adverse effects of sympathetic activation on heart failure compensation, thus improving the prognosis and relieving nausea and other uncomfortable symptoms; however, it is forbidden to use it for patients with bronchial asthma and severe bradycardia. When heart failure complicates nausea and other uncomfortable symptoms, it is recommended to consult the cardiovascular internal medicine department in time, under the guidance of the doctor for treatment, do not blindly use their own medication.
