Patients with hypertension can lead to the appearance of myocardial ischemia, which should be considered as follows: First, for hypertension, patients will increase the burden on the heart, which will especially trigger an increase in cardiac afterload. In the case of increased myocardial afterload, patients will experience varying degrees of inadequate blood supply to the coronary arteries, which will also trigger ischemia, stenosis, and spasm of the coronary arteries, which will in turn cause a state of ischemia and hypoxia in the myocardial cells. Secondly, patients with hypertension will have increased sympathetic tone, which will therefore lead to increased myocardial contraction, increased cardiac conduction velocity, increased oxygen consumption of myocardial cells, and increased cardiac contraction, all of which will lead to an imbalance between the oxygen supply and oxygen demand of myocardial cells, and therefore, myocardial ischemia will also occur. Thirdly, with long-term hypertension, patients will have insufficient return blood volume, therefore, it will further increase the incidence of myocardial ischemia.
