High blood pressure can indirectly cause chest tightness and chest pain. High blood pressure caused by myocardial ischemia can lead to the occurrence of chest pain, long-term high blood pressure can lead to coronary artery atherosclerosis, the coronary artery is an important channel for blood supply to the heart, oxygen supply, once affected by high blood pressure, there will be endothelial cell damage, caused by atherosclerosis plaque bulge, and ultimately lead to serious narrowing of the coronary arteries or even occlusion. Once the coronary arteries appear serious narrowing, myocardial blood supply is insufficient, the symptoms of chest tightness and chest pain will occur. Secondly, long-term hypertension blood pressure instability can lead to hypertensive heart disease, hypertensive heart disease can cause myocardial hypertrophy, causing the distal end heart muscle blood supply is insufficient, resulting in chest tightness, chest pain occurs. In addition, long-term hypertension may also induce aortic aneurysm, or even aortic dissection and other conditions, then, this situation will also produce severe tearing pain in the chest, and in severe cases, can endanger the patient’s life. Therefore, patients with high blood pressure need to pay attention to timely medical treatment, under the guidance of the doctor reasonable use of medication to control blood pressure stable, so as not to lead to target organ damage.
