STEMI, kematian jantung mendadak, takikardi ventrikelAbstrak
Pendahuluan: Takiaritmia ventrikel yang fatal di antaranya takikardi ventrikel (ventricular tachycardia/VT) atau fibrilasi ventrikel (ventricular fibrillation/VF) adalah penyebab tersering kematian jantung mendadak. Angka kematian di rumah sakit pada VT pada STEMI meningkat 4 hingga 5 kali lipat dibandingkan dengan STEMI tanpa aritmia ventrikular; VT dan VF juga awalnya dianggap sebagai penyebab paling umum dari henti jantung di luar rumah sakit. VT onset lambat (terjadi 24–48 jam setelah onset STEMI) adalah prediktor prognosis buruk. Kasus: Wanita berusia 49 tahun dengan nyeri dada terus-menerus selama 5 hari dan rasa berdebar-debar (palpitasi) selama 4 hari sebelum masuk rumah sakit. Pemeriksaan awal menemukan VT dan elevasi ST pada EKG, yang mengarah pada diagnosis STEMI anteroseptal dengan VT. Pengobatan meliputi aspirin, clopidogrel, heparin, isosorbide dinitrate, bisoprolol, dan simvastatin. VT teratasi sekitar 2 jam setelah pengobatan awal, dan evolusi STEMI (pada EKG) terlihat. Simpulan: Pengenalan dini dan pengobatan segera pada pasien VT dapat mencegah ketidakstabilan hemodinamik dan mengurangi mortalitas.
