The symptom that is caused directly from right ventricular heart failure (HF) and increased preload is jugular vein distension.
In right ventricular heart failure, there is a failure of the right ventricle to pump effectively, which leads to increased pressure in the systemic venous circulation. This increased pressure causes distention of the jugular veins, making jugular vein distension a key clinical sign of right heart failure.
The other options listed are more related to left ventricular failure or general heart failure effects rather than being specifically linked to right ventricular dysfunction.
