Dyspnea in cardiac hypertension may be due to the presence of coronary artery disease or heart failure, and specific medications may include nitroglycerin and digitalis. Heart disease hypertension itself does not cause dyspnea, but if combined with coronary heart disease or heart failure, etc. can appear typical dyspnea. 1. Coronary heart disease: long-term hypertension causes vitellogenic degeneration of coronary arteries, leading to coronary artery stenosis and coronary heart disease. These patients can take nitrate drugs, such as nitroglycerin, to relieve myocardial ischemia symptoms and relieve dyspnea. 2. Heart failure: heart disease and high blood pressure long-term recurrence, can lead to left ventricular hypertrophy, triggering heart failure. Should be routine anti-heart failure treatment, can take metoprolol, digitalis and other drugs. In addition, should not ignore the original respiratory system diseases caused by dyspnea, such as asthma. In short, patients should go to the regular hospital examination, under the guidance of the doctor for treatment.
