What symptom is left ventricular thickening

summary

I've been suffering from high blood pressure for about ten years. Now the symptoms are chest tightness, shortness of breath, abdominal distension, poor sleep, sometimes can't sleep at night. Color Doppler echocardiography showed left ventricular hypertrophy and septal thickening. What symptom does left ventricular hypertrophy have?

What symptom is left ventricular thickening

First, there are many causes of left ventricular hypertrophy, such as hypertension, coronary heart disease, hypertrophic cardiomyopathy, valvular disease (such as aortic insufficiency), etc, Ventricular contractility depends on the electrical activity of myocardial fibers

Second: with the continuous increase of aortic pressure, the original systolic force of the left ventricle has been unable to pump enough blood into the aorta to meet the needs of the whole body. At this time, myocardial cells can only proliferate, making the myocardium increase in number and similar in shape, so as to perform compensatory ejection. The increase in the number of myocardium will make the left ventricle hypertrophy in shape

Third: the number of myocardium increases, but its contractility can not be significantly higher than before, because the increased myocardial cells will consume more energy when doing work, increasing the burden on the heart. In addition, as mentioned before, the relative space and volume of the ventricle will be reduced due to the hypertrophy of the myocardium, and the volume of blood ejected at one time will be reduced. In fact, the intake fraction per minute will be reduced

matters needing attention

In the long run, myocardial hypertrophy can not improve the vicious circle of peripheral blood volume reduction in patients with hypertension
