Drugs to enhance cardiac function include aldosterone receptor blockers, RAAS inhibitors, β-blockers, cardiotonic drugs, and SGLT2i analogs. 1. Aldosterone receptor blockers: such as furosemide, hydrochlorothiazide, spironolactone, etc., can reduce blood volume by sodium drainage in order to reduce the volume load of the heart and improve cardiac function. 2. RAAS inhibitors: including ACEI drugs such as captopril and benazepril, and blood ARB drugs such as valsartan and chlorosartan, as well as sakubutra valsartan of the ARNI class can improve ventricular remodeling by decreasing the unfavorable effects of the neurohumoral compensatory mechanism; it can also play a vasodilator role by enhancing prostaglandin synthesis in order to reduce the afterload of the heart. 3. β-blockers: such as metoprolol, bisoprolol, carvedilol, etc., improve cardiac function by inhibiting sympathetic excitation, thus slowing down heart rate and increasing ventricular diastole. 4. Cardiotonic drugs: including digitalis drugs such as digoxin, molluscum sativum C, and non-digoxin drugs such as dopamine, milrinone, etc., which reduce heart rate by inhibiting conduction in the atrioventricular junction region of the heart, and also elevate intracellular calcium ion concentration and enhance myocardial contractility. 5. SGLT2i: including dagliflozin, eplerenone and engliflozin are three kinds of drugs, which can achieve the effect of increasing urinary sodium excretion, improving renal function, reducing anterior and posterior loads, decreasing the pressure of the left ventricular wall as well as decreasing interstitial edema. When heart disease such as heart failure occurs, it is important to go to the hospital in time for examination and treatment with medication as prescribed by the doctor.
