In brief: Whole books on this!

In a nutshell, left heart failure causes congestion in the lungs: breathlessness with exertion, when lying down, interfering with sleep, cough, coughing blood.
Right heart failure causes congestion in the abdomen and legs: enlarged liver, fluid in the abdomen (ascites), swollen intestines with loss of appetite, nausea, swollen genitals, swollen legs/ankles. They often occur together.
