What are the causes of right ventricular dysfunction?
summary
Right ventricular dysfunction is a common heart disease. The disease mainly refers to a pathological state in which the blood discharged from the heart is not enough to maintain tissue metabolism under the condition of normal venous return, so it is also known as congestive heart failure. What are the causes of right ventricular dysfunction? Next, I'd like to share my views with you.
What are the causes of right ventricular dysfunction?
Primary myocardial contractility is weakened, such as various myocarditis, cardiomyopathy and ischemic heart disease. Cardiac overload includes preload (volume load) and afterload (resistance load). Long term overload can lead to the decrease of secondary myocardial contractility.
Right heart failure is also called right heart failure. It is a kind of cardiac insufficiency. Pulmonary hypertension, pulmonary heart disease, pulmonary artery stenosis, atrial septal defect, cardiomyopathy can cause right ventricular dysfunction.
The clinical manifestations included cardiac enlargement (right atrial diameter and area, right ventricular base diameter and right ventricular middle diameter), increased heart rate, third or fourth heart sound, jugular vein distention, widened aortic diameter, widened distal diameter of right ventricular outflow tract, etc.
matters needing attention
Finally, it is necessary to remind the majority of patients that they must cherish their body in daily life, always pay attention to their health, and seek medical treatment immediately in case of discomfort, so as to prevent missing the best treatment opportunity.
