People with coronary heart disease will experience shortness of breath during angina attacks, for which patients mainly apply nitroglycerin and quick-acting heart-saving pills for short-term relief. If the shortness of breath is frequent, you can choose long acting ones such as isosorbide mononitrate or nicorandil to prevent shortness of breath attacks. For people with coronary heart disease, if there are frequent episodes of shortness of breath, accompanied by chest tightness and chest pain, it is important to go to the hospital for an electrocardiogram to assess whether there is acute myocardial ischemia. In terms of drugs, in addition to the application of the above coronary artery expansion drugs, the basic antiplatelet and lipid-lowering drugs also need to be applied. Because these two kinds of drugs can stabilize the plaque, and even have the possibility to shrink the plaque, to prevent the rupture of the plaque as well as the thrombosis caused by the instability of the surface of the plaque, these help to reduce the attack of angina symptoms. The main choices for drugs are aspirin and Rosuvastatin.
