Study group discussion: Right ventricular infarction

Since it's MI..Review question.. Name a disease associated with right ventricular infarction?

Atherosclerosis?

I meant name a cause for right ventricular infarction, other than atherosclerosis.

It's pulmonary embolism.

The pulmonary embolus puts the right side of heart in strain and it dilates. This dilation obstructs the right coronary artery. This was my viva question on an ECG of right ventricular infarct.

So does not it lead to hypertrophy of the right ventricle?
In an acute setting, no.
If the pulmonary thromboembolism  is chronic it will cause pulmonary hypertension. Then it causes right ventricular failure.

So the acute pulmonary embolus should be the answer.

Ohh that makes some sense! Good one!
