علماء يجدون مفتاحا لحماية القلب من التليّف بعد النوبات القلبية

ملخص الخبر

كشف العلماء عن إنزيم BCAT1 الذي يعزز تطور تليف عضلة القلب بعد النوبات القلبية عبر تزويد الخلايا بحمض البرولين.
أظهرت التجارب أن استخدام مثبط ERG240 لتعطيل هذا الإنزيم يقلل من تكون النسيج الندبي ويحافظ على وظيفة القلب.
أثبت الدثابت فعاليته في حماية القلب حتى عند البدء بالعلاج بعد سبعة أيام من الإصابة بنوبة قلبية.
أظهر تحليل أنسجة قلوب المرضى ارتفاع مستويات إنزيم BCAT1 في المناطق التي تعاني من تليف واضح.

ملخص كتبه الذكاء الاصطناعي من نص الخبر في مصدره.

أظهرت دراسة أجراها علماء جامعة ناغويا اليابانية أن تثبيط إنزيم معين في الجسم يساعد على تقليل تكوّن النسيج الندبي في القلب بعد النوبة القلبية، وقدرته على ضخ الدم.
