The common clinical antihypertensive drugs can be divided into the following five categories: 1. angiotensin-converting enzyme inhibitors, which are most suitable for patients with target organ damage such as heart and kidney, and have the effect of improving ventricular remodeling. 2. beta-blockers are most suitable for patients with combined coronary artery disease, which can slow down the heart rate and reduce myocardial oxygen consumption at the same time, and are beneficial to myocardial ischemia. 3. dihydropyridine calcium channel The diuretics are suitable for mild to moderate hypertension and can reduce heart failure while lowering blood pressure. 5. Angiotensin II receptor blockers are similar to angiotensin receptor inhibitors and are less likely to cause dry cough. The choice of drugs for hypertension should be individualized according to blood pressure fluctuations, comorbidities and other specific choices, and what suits you is the best.
