Summer heat, beware of a variety of incentives to cause acute myocardial infarction!
Acute myocardial infarction (AMI) is a kind of cardiovascular disease caused by coronary artery stenosis or occlusion leading to coronary blood flow interruption and thus myocardial necrosis. Its pathogenesis is coronary atherosclerosis. Plaque formation leads to lumen stenosis; atheromatous plaque rupture leads to platelet aggregation, activates the coagulation system, forms thrombosis and blocks coronary blood flow. It leads to persistent myocardial ischemia and hypoxia, causing myocardial necrosis.
Globally, the incidence and mortality of acute myocardial infarction is high, and it is more common in middle-aged and elderly people and high-risk groups with heart disease, diabetes, hyperlipidemia and hypertension. Long-term smoking, drinking, staying up late is easy to cause vascular lesions, and eventually lead to thick blood, acute vascular occlusion, resulting in serious consequences.
Summer is the peak of myocardial infarction, high temperature weather is easy to lead to increased blood viscosity, increased heart burden, leading to myocardial infarction. It's important to read the signs to prevent sudden death. A typical symptom of acute myocardial infarction is a sudden onset of intense and persistent retrosternal or precardiac crushing pain. This pain may sometimes radiate to the neck, jaw, pharynx, teeth, and even the upper back and inner left arm. The nature of the pain is usually crushing, constricting or choking, often accompanied by restlessness, sweating, fear and even a sense of near-death. Angina pectoris is the precursor symptom of acute myocardial infarction. When there is distension and pain in the precardiac area, accompanied by palpitations, shortness of breath, cold sweat and other symptoms, you should immediately call the emergency number 120 and go to the hospital for detailed examination and treatment.
If the air conditioning temperature is usually very low, or suddenly from a very hot external environment into a very cold indoor environment, drastic temperature changes are easy to lead to sudden contraction of blood vessels, increased blood pressure, and induced myocardial infarction.
In addition, the human body will sweat a lot when the summer high temperature, if the water supplement is not timely, it will lead to insufficient blood volume, increased blood viscosity, easy to form thrombosis, thereby inducing myocardial infarction. Because the human body may have a series of danger signals after sweating, these signals are often related to water and electrolyte imbalances in the body. Therefore, when we feel obvious thirst, dry mouth, dizziness, nausea, vomiting, palpitations, fatigue and other "signals", we must "understand" and timely hydration.
Studies have found that 90 percent of heart attacks can be prevented. Regular health check-ups can help early detection of signs of disease, timely treatment, and prevent further deterioration of the disease. "Chinese expert Consensus on myocardial troponin Laboratory Detection and Clinical Application" pointed out that cTn is the preferred marker for the diagnosis of acute myocardial infarction, and TnT and TnI have the same diagnostic value. cTnI/cTnT has also been unanimously evaluated by the American and European Society of Cardiology as a highly specific and highly sensitive diagnostic marker for the diagnosis of acute myocardial infarction. For patients with minor myocardial injury who cannot be changed by ECG and have no clinical typical symptoms, detection of cTnI/cTnT is also the best auxiliary diagnostic indicator at present.
Wizbiotech independently developed the cTnI assay kit, which can be completed in a short time, convenient, specific, sensitive and stable; Serum, plasma and whole blood can be tested. The products have been CE, UKCA, MDA certification, exported to many overseas countries, get the trust of customers. If you need this product, you can contact our sales consultation.
