Fractional Flow Reserve (FFR) is a diagnostic tool that aids decision-making in the treatment of coronary artery disease (CAD). FFR provides an objective measurement and is used as an adjunct to an angiogram. The clinical and cost-benefit of using FFR have been well established across published literature. This research was aimed at evaluating the economic impact of using FFR as an adjunct to angiogram versus an angiogram alone, in the Indian healthcare context.

A study from a tertiary care public hospital in India estimated the impact of using FFR as an adjunct to angiogram in management of CAD. This study was used to create a mathematical simulation model to estimate cost-effectiveness and economic impact of using FFR over seven years’ time horizon, from the Indian health systems perspective. A targeted literature review was performed to collect the clinical inputs for the model, and the national public health insurance program data was referenced to obtain the cost inputs.

A hypothetical cohort of 100,000 patients in the model reported 30 percent reduction in unnecessary stenting. Moreover, 14,025 deaths were averted with the adoption of FFR. In addition, there was a cost-saving of INR46,986 (574USD) per death averted and INR5,169 (63USD) per patient treated over a seven-year time horizon. The analysis demonstrated that FFR inclusion in the current clinical practice saves INR2,651 (32USD) per patient in overall upfront cost and INR2,518 (31USD) per patient in overall follow-up cost over a seven year follow-up period owing to improved diagnosis and prognosis.

In conclusion, FFR prevents unnecessary stenting, reduces overall mortality, and proves to be a cost-saving intervention in the long-term when used as a decision-making criterion in CAD patients in the Indian context.
