Actually, its interventional cardiology for heart attacks and neurointerventional surgery/interventional neuroradiology(NIR) for strokes. (Not IR which cover non-neurological and non-cardiological interventional procedures).
I'm a NIR and most of us are not paid per surgery/intervention. Also these interventions tend to be loss leaders in terms of hospital reimbursements. Funding for stroke centres can be profitable but that's a very long discussion.
In addition, at least 7 randomized clinical trials have shown the benefit of thrombectomy in acute stroke (actually something of a modern medical technological miracle).
