Does right heart failure lead to left heart failure?

Generally speaking, right heart failure does not lead to left heart failure.

Right heart failure is mainly caused by systemic congestion, while left heart failure is caused by pulmonary congestion. With right heart failure, right heart output decreases, pulmonary congestion performance decreases, and left heart load decreases relatively, so it usually does not lead to left heart failure. However, in turn, left heart failure can lead to right heart failure, because left heart failure leads to reduced left heart output, right ventricular afterload will gradually increase, when prolonged overload work, right ventricular failure will gradually occur.
