Microvascular angina treatment drugs: β-blockers, nicorandil, calcium channel blockers, angiotensin-converting enzyme inhibitors, statins and so on.
1. β-blockers: metoprolol succinate extended-release tablets, metoprolol tartrate tablets and so on. It is one of the first choice drugs for the treatment of microvascular angina pectoris, inhibits sympathetic nerve activity, lowers blood pressure, reduces myocardial oxygen consumption, slows down the heart rate, and exerts anti-anginal effects.
2. Nicorandil: It is a potassium channel blocker. It is suitable for all kinds of angina pectoris, and also has good effect on microvascular angina pectoris.
3. Calcium ion blockers: reduce intracellular calcium ions, can produce the biological effect of vasodilatation, with anti-anginal effect.
4. Angiotensin-converting enzyme inhibitors: they can improve the endothelial function of coronary microvessels, coronary blood flow index, and reduce the frequency of angina attacks.
5. Statins: can improve endothelial function, promote endothelium-dependent vasodilatation, in order to reduce the clinical symptoms of angina pectoris, for dyslipidemia accompanied by vascular endothelial dysfunction of the patient, can take statin therapy.
In addition, there are also nitrate drugs, Chinese patent medicines such as musk cardioprotective pills, etc. on microvascular angina pectoris has a certain effect on the relief.
If patients have been diagnosed with microvascular angina, they should follow the doctor’s instructions to standardize the use of drugs, avoid self-medication.
