Written by Coronary heart disease (coronaryarteryheartdisease, chd) referred to coronary heart disease , coronary heart disease is caused by what one of the most common heart disease is the result of coronary artery stenosis, cardiac insufficiency caused by dysfunction and (or) organic disease, it is also called ischemic cardiomyopathy (ihd). chd is the result of a variety of coronary artery disease, but coronary atherosclerotic coronary heart disease accounted for the vast majority (95% -99%). Therefore, it is customary to coronary heart disease as coronary heart disease (coronaryatheroscleroticheartdisease) synonyms. Caused by coronary heart disease causes:
About coronary heart disease is coronary artery disease by coronary organic (atherosclerosis hardening or power vasospasm) stenosis or obstruction caused by myocardial ischemia and blood oxygen ( angina ) or myocardial necrosis (myocardial infarction) of heart disease , also known as ischemic heart disease.
Coronary heart disease symptoms occurred a press of the central chest pain, and may delay to the neck, jaw, arm and stomach. It with angina not the same, even if you stop exercising, or in the tense mood disappears, it will continue to exist. Coronary heart attack and other possible symptoms include dizziness , shortness of breath, sweating, chills, nausea and fainting . Patients may be due to severe heart failure and death.
Disease Alias: What causes coronary heart disease coronary heart disease belongs parts: chest clinic departments : Department of Cardiology, Geriatrics symptoms and signs: sudden death, arrhythmia heart failure hypertensive heart palpitations abnormal breathing chest pain heart murmur and thrill the heart of physical examination: Dynamic electrocardiogram ECG disease agents: atorvastatin calcium capsule heart and brain heart capsule Ning Qi Long thrombolytic capsules (enteric-coated) tablets Diao Zhibituo self diseases: coronary heart disease myocardial infarction, coronary artery disease self self 1. artery atherosclerosis is the most common narrow coronary artery disease, especially coronary artery branch outside the muscle wall of atherosclerosis. The reason why the predilection of proximal segment of coronary artery atherosclerosis because it is better than all the organs are close to ventricle artery, which bear the greatest impact of systolic blood pressure. Furthermore, the coronary vascular tree because a majority of the heart shape the direction of change, so also exposed to greater blood flow shear stress.
Good site: What causes coronary heart disease, according to statistics of 6352 cases of autopsy, the overall detection rate of lesions, detection rate and the average level of stenosis were high before descending artery, followed by the right main, left main or left branch, after descending artery. Gender differences: 20 to 50 years old lesion detection rate was significantly higher than male female; 60 years of age no significant difference between men and women.
Lesions: the distribution of atherosclerotic plaque in the proximal segments and more, and heavier in the branch mouth; early, scattered patches, showing segmental distribution, with the progress of the disease, adjacent patches can be integrated with each other . Mostly in the crescent-shaped cross section of plaque, lumen showed different degrees of stenosis. Sometimes complicated by thrombosis , completely blocked the lumen stenosis according to the extent caused by plaque can be divided into four: grade stenosis of 25% or less; grade stenosis in 26% to 50%; level, a narrow 51% ~ 75%; grade stenosis of 76% or more.
2. Artery spasm over the years, academics have been around the coronary artery spasm is the cause of ischemic heart disease debate the issue. Cases of cardiac sudden death was found that the incidence of coronary thrombosis rate was 30%, within 12 hours after the onset of death is also only 50% of patients, so that at least a substantial part of cases are due to coronary artery spasm caused The. In recent years, carried out due to cardiovascular imaging technology has proven coronary artery spasm can cause angina and myocardial infarction.
3. Inflammation of the coronary artery can cause inflammation of coronary artery stenosis, or occlusion caused by ischemic heart disease, such as nodular nodosa, giant cell arteritis, Takayasu arteritis, wegener granulomatous disease, etc. coronary artery can be involved. Moreover, syphilitic aortitis can cause coronary artery stenosis, but are relatively rare.
How to prevent coronary heart disease
A reasonable diet, not a partial eclipse, should not be excessive. To control high cholesterol, high fat foods, eat a vegetarian diet. At the same time to control the total calorie intake, limiting weight gain.
2 should be the law of life, avoid excessive stress; maintain adequate sleep, training a variety of fun; to maintain emotional stability, should not irritable, agitated or depressed.
3 to maintain proper physical exercise activities to improve physical fitness.
4 non-smoking, alcohol abuse: tobacco can shrink the arterial wall and promote atherosclerosis; and alcohol is easily agitated, high blood pressure.
5 to prevent and treat chronic diseases: such as hypertension , hyperlipidemia, diabetes, and coronary heart disease closely related to these diseases.
Coronary heart disease to enhance the self-psychological adjustment in patients with coronary heart disease is mostly associated with peoples character has a lot of mental activity, so in our life, pay attention, psychological adjustment, the following four aspects to prevention, treatment of coronary heart disease:
1, failing to calm. Coronary heart disease is often fiery, it is easy to anger and offend others. Must constantly remind ourselves is wise to calm, increase patience.
