Abstract

Tatalaksana STEMI dengan onset yang timbul dalam 12 jam adalah reperfusi. Tatalaksana reperfusi apapun membutuhkan pemberian antiplatelet, terutama dual antiplatelet dengan kombinasi aspirin dan P2Y12 reseptor antagonis. Manajemen terapi antiplatelet pada pasien STEMI dengan trombositopenia memberi tantangan karena pasien memiliki resiko tinggi terjadinya perdarahan dan iskemia. Dilaporkan kasus pasien laki laki berusia 45 tahun dengan keluhan dada kiri terasa berat yang terasa sejak 2 jam lalu saat pasien sedang menyiram tanaman, keluhan dada kiri tidak menjalar ke hingga ke lengan kiri maupun dagu. Pada pemeriksaan fisik didapatkan keadaan umum baik, namun beberapa tanda vital meningkat. Hasil laboratorium menunjukkan penurunan trombosit dan hasil dari pemeriksaan enzim jantung didapatkan peningkatan dari Troponin-l. Pada hasil pemeriksaan ekokardiografi didapatkan hipokinetik pada mid anterolateral, apikal lateral, dengan kontraktilitas ventrikel kiri menurun dengan ejection fraction 48% dan TAPSE 2,1. Pasien didiagnosis STEMI inferior dengan trombositopenia dan pasien diberikan terapi berupa pilihan antikoagulan fondaparinux 2,5 cc dengan cek darah lengkap serial setiap hari. Pasien dipulangkan di hari ke-5 dengan terapi ramipril 1 x 5 mg, bisoprolol 1 x 5 mg, clopidogrel 1 x 75 mg, atorvastatin 1 x 40 mg dan spironolakton 1 x 25 m, dengan nilai PLT saat dipulangkan adalah 78 x 103 /uL.

Abstract

Takikardia supraventrikular adalah takiaritmia yang melibatkan jaringan atrium atau persimpangan atrioventrikular yang disertai dengan gejala klinis seperti palpitasi, sesak napas, atau bahkan tanpa gejala. Seorang wanita berusia 54 tahun dan seorang pria berusia 59 tahun datang ke UGD dengan keluhan berdebar tiba-tiba. Tidak ada aktivitas berat sebelumnya yang menjadi pemicu awal. Hasil EKG kedua pasien menunjukkan takikardia supraventrikular. Modifikasi Manuver Valsalva dilakukan pada kedua pasien, dan observasi selama 45-60 detik menunjukkan adanya pemulihan irama menjadi irama sinus. Modifikasi Manuver Valsalva bekerja dengan meningkatkan tonus vagal. Peningkatan tekanan intratoraks mencegah aliran balik vena perifer ke jantung kanan ketika pasien melakukan ekspirasi paksa. Ini akan mengaktivasi sistem saraf simpatis. Manuver Valsalva yang dimodifikasi telah menunjukkan bahwa tingkat keberhasilan konversi SVT dapat mencapai 43%, yang jauh lebih tinggi daripada Manuver Valsalva konvensional (17%) serta jauh lebih hemat biaya dan aman.

Abstract

Background: Antiplatelets are one of the cornerstones of treatment for Acute coronary syndrome (ACS), although it is risky in patients with thrombocytopenia. In choosing antiplatelets, physicians must carefully weigh the risks of ischemia and bleeding. Case Summary: A 68-year-old male came to ED with a 2-day history of left-sided chest pain, exacerbated 1 hour before admission. The preliminary ECG revealed ST elevation in lead V2-V5 and laboratory examination showed low platelets in four days (32x103/uL; 29x103/uL; 47x103/uL; 87x103/uL). The patient received a loading dose of Aspirin 160 mg. However, Clopidogrel 1x75mg was administered on the second day of treatment. After 5 days of treatment, the patient's condition improved, and his platelet count increased steadily. Conclusion: Antiplatelet therapy is required to avoid ischemic complications, but it enhances the risk of bleeding in individuals with thrombocytopenia. There have been few studies on the use of antiplatelets in thrombocytopenia. Monotherapy is preferred over dual therapy, however the risk/benefit ratio, clinical response, and monitoring for bleeding issues in the patient must all be considered. -- Highlights: 1. This case illustrates that cautious antiplatelet monotherapy may be a viable strategy in ACS patients with thrombocytopenia. In this 68-year-old with ST-elevation MI and platelets <50×10³/μL, delayed Clopidogrel monotherapy—guided by clinical stability and rising platelet counts—led to improvement without bleeding complications.

Abstract

Adult congenital heart disease is a cardiovascular condition that necessitates a comprehensive approach to medical and surgical intervention. In this condition, cyanosis results from a right-to-left shunt, which subsequently causes secondary erythrocytosis and hyperviscosity. Dehydration and iron deficiency can exacerbate the symptoms of hyperviscosity. One proposed strategy for reducingviscosity is phlebotomy. Phlebotomy procedures should be conducted with adequate fluid replacement to prevent acute stroke. While phlebotomy can reduce red blood cell mass and serum viscosity, it should be performed judiciously and not repeatedly to avoid stroke complications. Repeated phlebotomy without appropriate indications may lead to chronic iron deficiency and microcytic erythrocytes, which paradoxically increase the risk of cerebrovascular complications. Indications for therapeutic phlebotomy include moderate to severe hyperviscosity symptoms with hematocrit levels of at least 65% in the absence of dehydration or iron deficiency.The benefits of phlebotomy should only be considered when appropriate indications are met to achieve improved patient outcomes.
