Mitral tricuspid regurgitation does not usually cause hypertension, which has a complex etiology, including primary and secondary causes. Mitral tricuspid regurgitation can be seen in senile valvular disease, rheumatic heart disease, etc. The effect of valvular regurgitation on blood pressure is relatively small and rarely leads to hypertension; severe valvular regurgitation may lead to heart failure. Most patients with hypertension have primary hypertension, the exact cause of which is unknown and may be related to genetic factors, acquired environmental factors and other factors. Patients with secondary hypertension have a definite cause, such as kidney disease, endocrine disease, and renal artery stenosis. Patients who develop hypertension can undergo cardiac ultrasound to understand the function of the heart, but should be careful to undergo other tests to understand the cause of hypertension. If there is any discomfort, it is recommended to go to the hospital in time for treatment.
