Plump type _'s general knowledge of heart disease of myocardium disease
Summary
Plump type myocardium disease is plump as the characteristic with the cardiac muscle. Whether can be divided into obstructing and not obstructing plump type myocardium disease to obstruct to flow out one according to the left ventricle, unsymmetry interventricular septum plump to cause the intersection of aorta and petal lay getting narrow to claim special getting plump hair aorta one downed narrowly.
Cause of disease
Perhaps the factor is as follows,
First, heredity: There can be many people to have illness coming on in a family, it relates to heredity to point out.
Second, the endocrine is disorderly: Have a liking for the intersection of junket and the intersection of cell and compatible getting plump more myocardium patient, patient of tumour, human vein instil, send to myocardium necrosis by a large amount of noradrenaline. The intersection of animal and experiment, can cause the cardiac muscle to be plump while being intravenous to instil the catecholamine. Therefore someone thinks the plump type myocardium disease results from the reason that the endocrine is disorderly.
Symptom
There is a prominent difference among men and women of this disease, mostly symptom appears at 30- 40 years old, increase with age, symptom is more obvious, there are main symptoms Having difficulty in breathing, the labour has difficulty in breathing, present and sit up straight and breathe or popping seriously to have difficulty in breathing at the night. Angina pectoris; Often have typical angina pectoris, break out after the labour. Chest ache duration to be relatively long, suck, take, be invalid and can aggravate with Nitroglycerin. Faint and dizzy; Happen in fatigue more. Blood pressure drops, when the speed takes place or pass the slow arrhythmia, can also cause and faint and dizzy. Palpitation; The patient feels the heart beats strongly, especially lie on the left side in the location more obvious, may be caused by the fact that the arrhythmia or heart function changes.
Check
(1) X-ray examination: The heart is normal or increases in size, it is the direct radio that the pressure rank that heart size and heart and left ventricle shed during one is bad, the pressure steps are bad big, also the bigger the heart is. It is a main fact that the heart left ventricle is plump, the aorta is not increased widely, the lung artery section is not obviously outstanding, lung extravasated blood is mostly relatively light, the calcification of common bicuspid valve.
(2) Electrocardiogram: Because heart ischemic, it is extremely unusual for cardiac muscle to reply, it is common for ST-T to change, left ventricle plump and the intersection of Left deviation and bunch prop up block, more meet too, perhaps because Q wave appears in the plump and myocardium fiber of interventricular septum, this disease often has all kinds of arrhythmia.
(3) The interesting Fig. of the supersound: A important one is not the invading diagnostic method. Mainly behave and have The interventricular septum unusually increases thick, thickness of interventricular septum at the end of term of relaxation> 15mm. The interventricular septum moves the range is obviously reduced, is generally less than or equal to 5mm. The thickness ratio of the wall can be up to behind the interventricular septum thickness left room 1.5-2.5:1, have already diagnosed meanings in ratio that it is generally acknowledged> 1.5:1. The left ventricle shrinks the internal diameter of the end smaller than normal people. Shrink the initial time room to separate and often obviously shrink with the distance of the bicuspid valve frontal lobe. The bicuspid valve gets the interventricular septum near, stop before the second sound to sports before systolic phase. The aorta shrinks in middle period and closes. The analysis that the above 7 items should be comprehensive, can draw the correct conclusion, should pay attention to essential hypertension, the thyroid gland function bows, can cause and behave similarly.
(4) The heart conduit checks and cardiovascular vessel radiography: The heart conduit is checked, left ventricle and left ventricle appear in the pressure steps badly while flowing out one, left ventricle pressure increase latter stage such as relaxation, pressure steps flow out with left ventricle dish obstruct intensity is the positive correlation while being bad. The radiography of cardiovascular vessel, when interventricular septum muscles are plump and obvious, it is obvious the ventricle is presented narrow and long crack kind and changed, to diagnosing meaningfully.
Treat
Plump type myocardium disease is developed slowly, the prognosis is better, but not normal because of rhythm of the heart, can cause and die suddenly, should pay attention to avoiding overworking in life, it is excessively nervous to prevent, receptor blocks pharmaceuticals, propranolol can reduce myocardium contractile force, lighten the left ventricle flows out one and obstructs and improves the left ventricular wall and the left ventricle is plentiful, also resist the function of arrhythmia. Dosage: 10mg takes orally, 3 times a day. Can increase gradually, can reach 480mg day to the greatest extent. Can also block with the intersection of calcium and passway pharmaceutical is different to fight 40mg take orally 3 times a day definitely, nitre benzene pyridine 10mg, take orally, 3 times a day. Can improve the ventricle relaxation function, should pay attention to observing blood pressure, in case the blood is lowered too low.
Surgical treatment: The intersection of pressure and the intersection of steps and bad> 60mmHg, the intersection of medicine and person who fail to respond to any medical treatment, can perform the operation treatment. Feasible plump muscles excise the skill. Amalgamate the persons who can not be closed completely of serious bicuspid valve, can make bicuspid valves and replace the skill.
