What clinical manifestation does the plump type myocardium disease of knowledge have? 's symptom
How slow the disease is to get up! About 1/3 have family's history. Before symptom mostly begin with 30 years old. Men and women suffer from too.
Main symptom is:
Have difficulty in breathing, appear after fatigue more, because the left ventricle is lowered, relaxation is pressed and raised in latter stage, then lung venous pressure is raised, the reason of lung blood stasis. The bicuspid valve stored with the plump companion of interventricular septum can aggravate lung blood stasis.
The district ached before the heart, appeared after fatigue more, like angina pectoris, but can not be typical, is caused by the fact that the plump cardiac muscle is aerobic to increase but the coronary artery blood supply is relatively insufficient.
Weak, dizzy and fainting, much emergence while moving about, because the heart rate is accelerated, made originally the relaxation one has been full of not good enough left ventricle relaxation one to further shortened, made originally the relaxation one has been full of not good enough left ventricle relaxation one to further shortened, it is plentiful and insufficient to aggravate, the heart arranges blood volume to lower. Because sympathetic nerve apply enable the plump cardiac muscle shrink and strengthen when activity, or excited, aggravate and flow out one and obstruct, the heart arranges blood volume to sharply reduce and cause symptom.
Palpitation, because the heart function fails or due to arrhythmia.
In heart failure, see more the patient in later period, because the cardiac muscle is lowered, the ventricle is pressed and increased notably in latter stage of relaxation, then the atrium is pressed and risen, and often amalgamate the atrium and tremble. Patient myocardium fiber take extensive later period, ventricle shrink function subside too, incident and in heart failure dying suddenly.
Common physical sign is:
The heart voiced sound circle expands left. The apex of the heart beats and leaves shifting left, it is excited that there is praising. Or have the intersection of apex of the heart and pair beat, this to comply with whom ventricle that reduce produce arrange blood, beat before the apex of the heart beat touching atrium.
Sections of the intersection of apex of the heart and inside can hear, shrink middle period or later period injection noise under the the intersection of brestbone and left reason, but does not spread to the bottom of heart to the apex of the heart, can tremble with systolic phase, see having ventricles to flow out a patient obstructing. Measure foreign digitalis, the different third Epinephrine (2 g/min) such as giving increasing myocardium contractile force or lightening heart load Inferior the intersection of nitric acid and different the intersection of fifth and ester, Nitroglycerin, make the intersection of Valsalva and movement, can make the noise strengthen beat too early, after the manual labor; If the measure weakening myocardium contractile force or increasing heart load shrinks medicines for the blood vessel, receptor blocks pharmaceuticals, squats down, can make the noise weaken while holding the palm tight. About half the a patient can hear bicuspid valve close the noise not complete at the same time.
The second sound can be presented abnormally and split, because the left ventricle gushes out the blood and is obstructed, a delay of aorta is closed. The third sound is common closing the patient not complete with the bicuspid valve.
