The China Cardiovascular Disease Report 2018, released by the National Cardiovascular Center, shows that the number of people with cardiovascular disease in China is now 290 million, higher than tumors and other diseases, ranking first. Rural cardiovascular deaths account for 45.50% of all causes of death, and urban cardiovascular deaths account for 43.16% of all causes of death. Cardiovascular disease is also the number one health killer worldwide, accounting for nearly 30% of all deaths worldwide, and the incidence of cardiovascular disease is increasing every year. Today we come to seriously learn and understand high-risk cardiovascular diseases, why the mortality rate is so high, how to determine and how to prevent! 1, the two major diseases with the highest incidence and mortality rate in cardiovascular diseases 1) coronary heart disease: the rising trend of mortality is obvious! According to the China Health and Family Planning Statistical Yearbook (2017), the mortality rate of coronary heart disease in urban and rural residents in China in 2016 continued the upward trend since 2012.The overall mortality rate of acute myocardial infarction from 2002 to 2016 still showed a rapid upward trend. The causes of sudden death from coronary heart disease are as follows. â‘ Sudden blockage of the main branches of the coronary arteries supplying blood to the heart usually caused by thrombus, resulting in massive acute ischemia and necrosis of the myocardium. â‘¡Insufficient supply of oxygen and nutrients required by the myocardium after acute myocardial infarction, leading to myocardial rupture. (3) On the basis of atherosclerosis, coronary artery spasm occurs, resulting in cardiac electrophysiological disorders, causing severe arrhythmias (such as ventricular fibrillation) and leading to cardiac arrest. 2) The rate of sudden cardiac death from arrhythmia is extremely high! According to statistics, there are about 10 million patients with atrial fibrillation in China, and the risk of stroke in patients with atrial fibrillation is 5 times higher than normal people. Stroke occurs in about 5-10% of patients with AF each year, and more than half of them will be fatal and disabling, with hemiplegia, visual or speech impairment, and dysphagia and a series of other complications, causing a great burden to patients and families. Malignant arrhythmias can lead to sudden cardiac death. The sudden disruption of the heartbeat causes it to fail to eject blood effectively, which in turn interrupts the blood supply to the brain. If the rescue is not timely, the person will not be able to die immediately. According to the latest data, the number of sudden cardiac death in China exceeds 540,000 each year, which is equivalent to about 1,500 people passing away every day. And the success rate of out-of-hospital emergency cardiac death is only 1%. 2, sudden cardiac death, not far from us, but there are signs to find! Especially in patients with cardiovascular disease, the incidence of sudden cardiac death is much higher than the general population. However, before sudden cardiac death occurs, most patients will have certain signs: 1) chest tightness, chest pain; 2) breathing difficulties, weakness; 3) panic, palpitations; 4) increased or reduced blood pressure; 5) dizziness, drowsiness. However, these symptoms are often overlooked by patients, mistakenly thought to be caused by mental stress of exertion, wrong assessment of the condition, resulting in failure to seek medical attention in a timely manner, and tragedy can occur. Therefore, if you can detect the sudden cardiovascular death in advance, it will help to avoid sudden cardiovascular death. We all know that heart disease is difficult to detect when the general examination is not onset, if you can monitor the ECG changes when these signs onset can mostly help determine the disease. 3, sudden cardiac death is frequent, how to prevent it from happening in life? The incidence of cardiovascular disease is high, and the onset is very rapid, many people work or life, a sudden attack of heart disease, before the treatment and passed away. For many people at risk, it is important to monitor their heart health in real time and to provide early warning. Sudden cardiac death is frequent, cardiovascular risk groups need to pay more attention to their own health, monitoring their own heart rhythm and blood pressure, there are many smart bracelets, watches on the market can only simply monitor the heart rate can not do the same as the hospital professional equipment ECG monitoring function. Some people at high cardiovascular risk buy handheld heart smart butler, which is very small and can be carried around, and implement monitoring to play the role of ECG monitoring, and can warn of a variety of arrhythmic events. Double warning mechanism for malignant arrhythmia events. Especially for people at high risk of cardiovascular disease, it can keep the heart away from danger. Early warning judgment, which is a good choice. 4.How to implement self-help for heart disease + wait for rescue? When a heart attack occurs, immediately call 120 at home and wait for rescue. The following ways can save yourself: 1) lie down and rest, keep air circulation, relax and avoid tension; 2) measure blood pressure and heart rate; 3) keep the phone open to ensure that 120 can communicate at any time. In the case of coronary heart disease, you can take 1 nitroglycerin tablet under the tongue or chew it, and if the symptoms are not relieved, take nitroglycerin tablets again after 10-15 minutes. 2 hours after the onset of acute myocardial infarction is the golden time, with the passage of time, the area of myocardial necrosis will further expand, and eventually heart failure, shock or even death, acute heart attack 2 hours of small-scale myocardial ischemia, myocardial necrosis, 6 hours about 50% of myocardial ischemia, myocardial necrosis, 12 hours almost 100% myocardial necrosis, more than 12 hours when the myocardium will weaken, produce shock or even death. Every minute is the key to rescue. 5, correct risk factors, prevention and control of heart disease is imperative! Usually, we should pay attention to whether we have risk factors for heart disease: smoking, alcoholism, overweight and obesity, lack of physical exercise, staying up late, insomnia, high blood pressure, high blood lipid, high blood sugar, long-term mental stress, etc. For these high-risk groups, we should correct the risk factors. For the above high-risk groups, these risk factors should be corrected. To develop good lifestyle habits, we must quit smoking and limit alcohol consumption. For people with “three highs”, we must actively treat them and keep the indicators within the normal range. To adhere to appropriate exercise, to control the weight of a reasonable level. Adhering to a healthy lifestyle is important to prevent and treat heart disease. Finally, I tell you that cardiovascular disease itself is not terrible, the most important thing is the need for early identification, early warning, early prevention, if necessary, the use of portable cardiac monitoring equipment, so that early warning, reduce the occurrence of sudden cardiovascular death, to protect heart health.
