BACKGROUND: Few studies have analyzed the cost of treatment of chronic angina pectoris, especially in European countries. AIM: To determine, using a modeling approach, the cost of care in 2012 for 1year of treatment of patients with stable angina, according to four therapeutic options: optimal medical therapy (OMT); percutaneous coronary intervention with bare-metal stent (PCI-BMS); PCI with drug-eluting stent (PCI-DES); and coronary artery bypass graft (CABG). METHODS: Six different clinical scenarios that could occur over 1year were defined: clinical success; recurrence of symptoms without hospitalization; myocardial infarction (MI); subsequent revascularization; death from non-cardiac cause; and cardiac death. The probability of a patient being in one of the six clinical scenarios, according to the therapeutic options used, was determined from a literature search. A direct medical cost for each of the therapeutic options was calculated from the perspective of French statutory health insurance. RESULTS: The annual costs per patient for each strategy, according to their efficacy results, were, in our models, €1567 with OMT, €5908 with PCI-BMS, €6623 with PCI-DES and €16,612 with CABG. These costs were significantly different (P<0.05). A part of these costs was related to management of complications (recurrence of symptoms, MI and death) during the year (between 3% and 38% depending on the therapeutic options studied); this part of the expenditure was lowest with the CABG therapeutic option. CONCLUSION: OMT appears to be the least costly option, and, if reasonable from a clinical point of view, might achieve appreciable savings in health expenditure.
