In recent years, the number of people suffering from cardiovascular diseases has been increasing, and coronary heart disease is one of them. There are a lot of people do not understand in the end high blood pressure and coronary heart disease has what kind of relationship? Unbeknownst to them, hypertension is one of the most important risk factors for coronary heart disease, the reasons are: 1. When blood pressure rises, the pressure in the arterial vasculature increases, and the long-term impact of high-pressure blood flow on the blood vessel wall leads to mechanical damage to the arterial endothelium, and the higher the blood pressure, the more serious the damage is. As the coronary artery originates from the ascending aorta, the impact of high pressure blood flow is larger, easy to be injured; 2, elevated blood pressure will also affect the metabolism of connective tissue in the arterial vasculature, so that the lipid content of the blood is easy to invade and deposit into the vessel wall, accelerating the formation of coronary atherosclerosis; 3, hypertension patients are often accompanied by neurological and endocrine disorders, increased release of catecholamines, which can directly damage the arterial vasculature, leading to coronary atherosclerosis. Arterial vessels, resulting in coronary artery spasm, accelerating the formation of coronary artery atherosclerosis; 4, hypertensive patients often have a large number of smoking, drinking, mental stress and other bad lifestyle, these are risk factors for coronary heart disease; doctor’s note: hypertension is a risk factor for coronary heart disease, some patients with coronary heart disease are combined with hypertension, and with the rise of blood pressure, the risk of coronary heart disease is also gradually increased. The level of blood pressure directly affects the condition of coronary heart disease, timely control of blood pressure has an important role in the prevention of coronary heart disease.
