Qon oqimining fraksion zaxirasi (FFR) koronar stenozlarning funksional baholashining oltin standarti hisoblanadi, ammo uning klinik amaliyotda qo‘llanilishi, hozirgi kungacha Markaziy Osiyoda cheklangan bo‘lib qolmoqda. Ushbu klinik holat 70 yoshli bemorda toj tomirlarning ko‘p tomirli aterosklerotik zararlanishida revaskulyarizatsiyaning FFR-ga yo‘naltirilgan strategiyasining amaliy ahamiyatini ko‘rsatadi. Koronar angiografiya natijalariga ko‘ra oldingi tushuvchi arteriyaning chegarali stenozi (55-60%) va aylanib o‘tuvchi arteriyaning kritik stenozi (90-95%) aniqlandi. FFR tekshiruvi natijalariga ko‘ra aylanib o‘tuvchi arteriya stenozining gemodinamik ahamiyatliligini (FFR 0.69), oldingi tushuvchi arteriyaning esa funksional ahamiyatsizligini (FFR 0.93) ko‘rsatdi. Fiziologik baholash asosida faqat aylanib o‘tuvchi arteriyani stentlash amaliyoti bajarildi va oldingi tushuvchi arteriyada teri orqali aralashuv kechiktirildi. Mazkur holat FFR ning asosiy afzalliklarini ko‘rsatadi: teri orqali aralashuvlarda qarorlar qabul qilishni obyektivlashtirish, keraksiz stentlashdan voz kechish, amaliyot xavflarini kamaytirish va uzoq muddatli natijalarni optimallashtirish. FFR ning klinik amaliyotga integratsiyasi interventsion kardiologiyada shaxsiylashtirilgan tibbiyotga muhim qadam hisoblanadi.
