Quebec City, Quebec, April 24, 2018 – Opsens Inc. (“Opsens” or the “Company”) (TSX:OPS)(OTCQX:OPSSF) applauds Japan’s Ministry of Health, Labor and Welfare (“MHLW”) on its new regulation requiring the evaluation of any coronary stenosis prior to its treatment, specifically mentioning Fractional Flow Reserve (“FFR”) as a preferred assessment method.

The MHLW recently revised medical fees and established a requirement that functional ischemia (blockage of arteries) be evaluated before treatment for stable coronary artery disease.

This new review regulation is consistent with the results of multiple studies, such as the FAME study, which demonstrate that, when a patient’s lesion is assessed with FFR prior to treatment selection, clinical outcome is improved significantly.

The MHLW regulation is expected to have a positive impact on FFR penetration in the Japanese market, which currently represents the largest user of Opsens’ FFR products. Opsens’ revenues may be positively impacted as soon as the fourth quarter of fiscal year 2018.
