Exertion and anger are often the causes of angina. If angina is caused by such conditions, the patient should stop physical activity immediately. If the angina is caused by anger and emotional excitement, it is very important to calm down as soon as possible. At this time, you can also take nitroglycerin to dilate the coronary vessels, increase coronary blood flow and reduce myocardial ischemia. At the same time, beta-blockers can be taken to reduce the number of heart beats, lower the heart rate, reduce myocardial contraction and relieve angina. If atherosclerosis causes severe stenosis in the pipeline, it can also be combined with interventional therapy to control angina. High attention should also be paid to non-invasive treatment techniques, such as extracorporeal counterpulsation, which have good efficacy for all types of angina control.
