Coronary heart disease can take angiotensin-converting enzyme inhibitors, aldosterone receptor antagonists, beta receptor antagonists can improve heart function. 1. Angiotensin-converting enzyme inhibitors: If patients have coronary heart disease, they can take angiotensin-converting enzyme inhibitors, such as captopril, benazepril, ramipril, etc., to reduce the adverse effects of neurohumoral compensatory mechanisms in patients with heart failure and improve ventricular remodeling. 2. Aldosterone receptor antagonist: If patients have coronary heart disease, they can take aldosterone receptor antagonists, such as spironolactone and eplerenone. Improve the long-term prognosis of patients with coronary heart disease. 3. β-receptor antagonists: patients with coronary heart disease can take β-receptor antagonists, such as bisoprolol, metoprolol, carvedilol and so on. They can slow down the heart rate, reduce symptoms and improve the prognosis of patients with coronary heart disease. It is recommended that patients with coronary heart disease go to the hospital in time, under the guidance of the doctor for medication, do not self-medication.
