Draw back narrow pericarditis and common complication --Ischemic _'s symptom of the cardiac muscle
The cardiac muscle is ischemic, mean the blood of the heart is poured into and reduced, the ones that cause the heart are for oxygen to reduce, the myocardium energy supersession is abnormal, a kind of pathologic state that can't support the heart to work normally. The blood supply of the heart is not unalterable, but fluctuate existing all the time, but this kind of fluctuation undergoes the autoregulation of organism, impel the supply and demand of blood to be relatively invariable, guarantee the heart works normally. If any kind of reason causes the cardiac muscle to be ischemic, regulate and can't meet heart work's needs by the organism, this forms real cardiac muscle ischemically.
Why is the heart ischemic? Blood pressure reduce and the intersection of aorta and blood supply reduce, preceded arterial occlusion of form, can lead to the fact directly the blood supply of heart is reduced; Heart valve disease, blood viscosity change, cardiac muscle own pathological change will make the blood supply of heart reduce too. Another kind of situation, the blood supply of heart was not reduced, but heart oxygen demand increases, this is that a kind of relative cardiac muscle is ischemic. Called the coronary artery, open in promoting the aorta for the blood vessel of the blood supply of heart.
Reveal clinically: Cause ischemic and main, most common cause of disease of the cardiac muscle, a coronary artery is narrow. And the main reason the coronary artery is narrow is atherosclerosis. Heart disease that atherosclerosis of form cause is coronary heart disease that everybody often talks about because preceded. So, coronary heart disease is the cardiac muscle ischemic " root of the trouble " .
Cardiac muscle is ischemic may all bring a lot of adverse effects on heart and whole body. Oxygen is a material that a myocardium cellular activity is essential, and oxygen is transported to cells through the blood. There is not the heart " Oxygen warehouse " ,Totally rely on the myocardium blood to support, so is once ischemic, will cause oxygen deficiency at once. The direct consequence of oxygen deficiency is that myocardium cell aerobic metabolism is weakened, can reduce to produce, make heart to be at the activity essential energy insufficient in supply, cause angina pectoris, arrhythmia, heart function to drop. Meanwhile, the wastes of the supersession can't be removed effectively in time either, it is apt to exert an unfavorable influence. Ischemic, oxygen deficiency, lacking energy, will influence the shrink function of the heart finally. If have 20% - 25% Cardiac muscle stop shrink,usually can left without being appeared depleted in function in room; If over 40% of the cardiac muscle can't shrink, there is a severe depleted cardiac pump function. If this kind of situation took place suddenly, will present very dangerous heart source shock. Acute myocardium infarction often correlates with this kind of situation.
The cardiac muscle is ischemic will also damage the relaxation function. Shrink badly and it is combined together that relaxation is bad, it is apt to cause the ventricle to be plentiful to press and rise, cause the lung to be congested, can cause complicated disorder of substance metabolism and electric activity of cardiac muscle to be not normal. So, once the cardiac muscle appears ischemically, should find the treatment to the ill of the cause of disease accurately, can avoid the potential serious consequence.
Ischemic scheming a of coronary heart disease, for choose the intersection of nitric acid and the intersection of fat and medicine (clear up dosage forms slowly such as single the intersection of nitric acid and different the intersection of mountain and the intersection of pear and lipoprotein or their) healing solution ,Function is in order to expand the heart coronary artery, increase the myocardium blood supply; Should take his spit of fland type medicine even ' If A cuts down his spit of fland, cuts down his spit of fland hard) Reduce cholesterol in the blood plasma on one hand, stabilize the artery spot piece on the other hand, prevent the spot piece from lossing and forming the thrombus, cause apoplexy,etc..
Have symptom while being so-called cardiac muscle ischemic to mean coronary heart disease diagnose confirm ischemic objective index of the cardiac muscle, for instance electrocardiogram model ischemic section ST change,etc., it is a kind of special type of coronary heart disease. But is often ignored by people because of not there is not symptomming.
Have symptom cardiac muscle ischemic to pay attention to day by day, because of a large number of findings in recent years mainly, in about 25%- 50% of the acute persons who die suddenly, there is no angina pectoris to break out in the history before death; But in nearly 90% of the corpses are examined, find these per persons have serious the first atherosclerosis and pathological change. About 2%- 4% of the seemingly healthy middle-aged persons who has symptom in U.S.A., it is and not so ischemic as cardiac muscle of symptom to have obvious coronary artery and pathological change to discover to check and break out. The reason to die suddenly is usually the arrhythmia of mortality, but before the fast room arrhythmia of the mortality breaks out, the electrocardiogram can be detected not to be so ischemic as cardiac muscle of symptom there may be causality when and dies suddenly. In addition someone report U.S.A. have 450,000 people die suddenly every year, among them 20%- 50% die of getting slow not normal rhythm of the heart, it is before this or concurrently with,it it is there will be symptom ischemic cardiac muscle not to accompany often. Also someone followed up a case by regular visits to to find while observing, 25% of the myocardium infarction has no symptom in 30 in 5209 coronary heart diseases patient, mortality is 84% in its 10 years. The result shows, the rate, case fatality rate and dying suddenly rate with myocardium infarction of symptom are similar to case fatality rate that myocardium infarction of symptom that do not have dies suddenly. Even in the patient of acute myocardium infarction has already taken placing, 30% of the patients have no symptom, this indicates the cardiac muscle is residual and ischemic around infarction, this kind often causes myocardium infarction again and dies suddenly residually and ischemic. Not so ischemic as cardiac muscle of symptom on medical science at present to divide into the following three types: Type, security is myocardium ischemic without being symptommed: This type has no symptom, being discovered and have cardiac muscle accidentally is ischemic, someone estimates in the middle aged men without coronary heart disease and symptom at all (general crowd) Accounts for 2%- 5%. Its prognosis is similar to angina pectoris patient.2Type, have in myocardium behind infarction one by cardiac muscle on symptom ischemic: Really ischemic persons who exist of cardiac muscle comparatively see more to although there is not angina pectoris after myocardium infarction. This kind of patient's prognosis is relatively type worse, especially when the left ventricle function is unusual, its mortality is 5%- 6%. Type, angina pectoris companion symptom myocardium ischemic: Studies have suggested 70%- 80% do not have ischemic cardiac muscle of symptom at the same time in the angina pectoris patient, and can take place in different kinds of angina pectoris. Must point out, the not steady angina pectoris patient accompanies ischemic arrhythmia that can often cause the mortality of symptom of cardiac muscle, symptom disappear but still have cardiac muscle to be ischemic to exist after treating, this the intersection of prognosis and bad important index.So have symptom cardiac muscle should cause people's enough attention while being ischemic. It can influence the prognosis of various coronary heart diseases, so should diagnose and treat actively.The ischemic one of cardiac muscle should pay attention to diet, six words, the high fiber of low fat. Should pay attention to not needing the great sorrow with great rejoicing on mood, keep the sufficient sleep. Form the good habits and customs, defecate regularly, can't be overworked.
