What is Coronary artery disease?
Coronary artery disease is another term used for atherosclerotic heart disease, a condition caused by a narrowing, hardening and furring of the walls of the coronary arteries. The coronary arteries supply oxygen and nutrients to the muscles of the heart called the myocardium. Coronary artery disease is also often called coronary heart disease (CHD)
Cause:
Cholesterol deposition (atherosclerosis) or inflammation in damaged inner walls of the arteries is the main cause.
The following are risk factors for inner wall damage:
High blood pressure
High blood cholesterol levels
Tobacco use or smoking
Diabetes
Family history of heart diseases
Obesity
Sedentary lifestyle
Age
Gender: Men are at higher risk
What are the Symptoms of Coronary artery disease?
Symptoms of CAD are not noted until the artery is significantly damaged
Severe artery damage decreases blood flow to the heart, which presents as
- Angina or chest pain that spreads across the chest
- Shortness of breath
- Heart attack is experienced if the coronary artery is completely blocked
Other associated symptoms include:
- Nausea
- Sweating
- Fatigue
- Faster heartbeat
- Weakness or dizziness
Introduction:
The 650nm weak laser treatment of cardiovascular and cerebrovascular diseases began in the 1970s. Therapeutic methods have undergone a history of blood draw recovery therapy, intravascular irradiation therapy, extravascular irradiation therapy, and intranasal irradiation therapy. The device has experienced the development of 氦-氖 lasers to semiconductor lasers. Because the semiconductor laser in the nasal cavity has great advantages over the 氦-氖 intravascular irradiation, such as: small size, light weight, convenient operation, long life (5 times longer than 氦-氖 laser), low price, energy conversion High rate, no pain, no damage, etc., has become the most effective instrument for family treatment of cardiovascular and cerebrovascular diseases.
Principles of physical therapy:
The weak laser at 650 nm wavelength irradiates the human iliac artery. After the laser passes through the skin, muscles and blood vessel walls of the human body, the red blood cells in the blood absorb the laser energy, restore its normal charging performance, and promote the dissolution of the lipid layer on the surface of the red blood cell. To achieve effective blood sugar lowering, blood loss and adhesion.
Features:
Weak laser irradiation can regulate and stimulate the surface charge of transformed red blood cells, improve the aggregation and suspension stability of red blood cells, reduce hematocrit, increase the deformability of red blood cells, reduce the viscosity of whole blood, and improve blood rheology. Thereby improving coronary microcirculation disturbance, reducing total peripheral resistance of blood vessels, significantly increasing left ventricular output, and improving hemodynamics (because patients with coronary heart disease often have red blood cell stability disorder, increased red blood cell and platelet aggregation, and reduced red blood cell deformability) The whole blood viscosity increases, thus causing myocardial microcirculatory disorders).
The core problem of coronary heart disease is myocardial hypoxia and myocardial blood supply disorder. Zhou Lingyun research indicates that weak laser irradiation can improve the oxygen carrying capacity of hemoglobin, activate superoxide dismutase, etc., thereby accelerating the elimination of free radicals and relieving lipid peroxides. The destruction of the membrane system can restore the function of the biofilm, and the function of myocardial energy metabolism and conduction system can be improved, thereby delaying the occurrence and development of atherosclerosis.
Accelerated the elimination of oxygen free radicals and lipid peroxides, can improve the balance of thromboxane-prostacyclin, inhibit platelet activation, prevent thrombosis and coronary spasm, improve myocardial ischemia and hypoxia, and thus lead patients with coronary heart disease The number of angina attacks is reduced and the duration is shortened.
