The high incidence period of cardiovascular disease is coming
The weather is getting colder and colder, autumn is about to leave, winter is coming. Cardiovascular disease will also enter a period of high incidence, and we must have people around us, have cardiovascular disease. So it's important to know how to effectively prevent and treat it. Today, I will give you a detailed introduction ~
01 Cardiovascular disease has always been a high incidence of human diseases, morbidity and mortality are very high, and even increasing
CDC experts suggest that 50 percent of cardiovascular disease is attributable to lifestyle (smoking, poor diet and lack of exercise), 20 percent to genetics, 20 percent to environmental factors and 10 percent to patient treatment. However, the current situation is turning before the horse, with most efforts focused on the later treatment of the disease and an apparent lack of prevention.
Professor Michael Wolk, the newly appointed 53rd ACC President, therefore called on cardiovascular specialists to move from intervention to prevention and protection of human health when people are healthy, rather than waiting for heart disease to get out of control. Since 1970, mortality from cardiovascular disease has been reduced by 50% in the United States through lifestyle changes, prevention and treatment of high blood pressure and hypercholesterolemia, and advances in treatment technology, and the reduction in stroke since 1950 has been even more dramatic.

For example, in prevention studies in our country, prospective studies in our country concluded that for every 5mmHg change in diastolic blood pressure, the risk of stroke changed by 46% and the risk of coronary heart disease events changed by 24%.
02 There are many cardiovascular diseases, mainly hypertension and acute myocardial infarction, with numerous symptoms and pathologies
Hypertension is the most common chronic disease, and different patients have different blood pressure values. The target blood pressure reduction for the general patient is less than 140/90 MMHG, while the target blood pressure for older patients aged 65 years or older is 150/90 MMHG. It can be tolerated and can be further reduced to below 140/90 MMHG, with a target value of 150/90 MMHG in patients ≥80 years of age. There are many pathogenesis, the following are discussed several types of pathogenesis,
Neural mechanism: The sympathetic nervous system is over-activated, causing excessive release of catecholamines, such as in a relaxed state, catecholamines are over-released.
Renal mechanism: The kidneys cause water and sodium retention and excessive blood volume load.
Hormonal mechanism: The renin-angiotensin-aldosterone system is over-activated, resulting in water and sodium retention.
Vascular endothelial mechanism: Vascular endothelial function decreases, carbon monoxide release decreases, causing excessive vasoconstriction.
Acute myocardial infarction is the most dangerous type of coronary heart disease. From 2002 to 2017, the death rate increased, and since 2005, it has increased rapidly. Awareness of heart attacks is uneven among residents. People under 50 years of age had the worst awareness, with more than 70% unaware of key treatments for acute myocardial infarction (including thrombolysis and emergency interventional therapy).
Persistent chest pain and profuse sweating are the most typical clinical manifestations. Typical symptoms of chest pain, such as fatigue, nausea, shortness of breath, heart, stomach or radiating pain in the shoulder and neck.
If these symptoms occur, you should seek medical attention promptly. After a diagnosis of coronary heart disease, antiplatelet drugs, as well as beta-blockers and other drugs should be taken regularly, and if conditions permit, coronary angiography, if necessary, vascular reconstruction therapy.
03 How to prevent cardiovascular disease, do these four aspects, or can help you stay away from cardiovascular disease
In autumn and winter, the temperature drops, the temperature difference between day and night increases, the possibility of blood vessel contraction, blood pressure rise is greater, and the fluctuation is obvious. Please note the following:
1, for the blood pressure is significantly increased or drastic fluctuations of friends, should seek medical attention and adjust the medication in time;
2, some people with high or low blood pressure will have obvious symptoms, such as dizziness and headache, but some patients still have no symptoms.
3, asymptomatic patients should also follow the doctor's advice, regularly monitor blood pressure, and adjust the drug according to blood pressure.
4, don't overjoyed, don't be too sad or impatient. You should also limit the amount of salt and other foods in your diet.
Conclusion: Although the cardiovascular problem is terrible, but more terrible is that too many of us do not pay attention to it, pay attention to its character. So that we hurt it again and again in life, and we don't know it. After reading this article, you must have been a master of blood vessel protection, quickly practice it.
