Blockers; V. Angiotensin-converting enzyme inhibitors and angiotensin II receptor antagonists that regulate blood pressure and prevent ventricular remodeling. All of these drugs should be taken according to medical prescriptions, and can also be combined with blood circulation and blood stasis herbal treatment.
