Background: Cardiac arrest is one of the leading cause of death in the world with steadily increasing number over the years. Basic life support has been proven to lower the risks of tissue damage and further complication.Several study shows that BLS skill are lacking in some doctors and nurses. Objective: Therefore, the purpose of this study is knowing the retention of basic life support in medical student of Airlangga University. Methods: This descriptive study used cross sectional design. Subjects were students at faculty of medicine in Airlangga University who trained one year ago and completed their study of Basic Life Support. Fifty two subject were asked to practice their BLS techniques then scored based on modified American Hearth Assosiation (AHA)'s Basic life support skill checklist. Results: Based on the data, the percentage of students who did the retest correctly: response checked by shouting 92.31% students, response checked by tapping 69.23% students, call for help 44.23% students, airway checked 48.08% students, breathing checked 46.15% students, correct hand placement 100% students, compression rate 78.85% students, compression ratio 75% students, position 94.23% students, and compression depth 78.85% students. Conclusion:One year post training and test, 14 from 52 students could complete all the steps in basic life support skill. Less than a half of the students successfully done 3 out of 10 points that were being tested. Meanwhile, many aspects in circulation point show higher results all above 75%. Latar Belakang: Henti jantung merupakan salah atau penyebab kematian tertinggi di dunia dan jumlahnya meningkat dari tahun ke tahun. Basic life support atau bantuan hidup dasar (BHD) terbukti dapat menurunkan kerusakan jaringan dan komplikasi lebih lanjut. Beberapa penelitian menunjukkan ketrampilan BHD pada tenaga medis, baik dokter maupun perawat masih kurang. Tujuan: Melalui penelitian ini dapat diketahui retensi mengenai ketrampilan BHD pada mahasiswa Fakultas Kedokteran Universitas Airlangga. Metode: Penelitian ini merupakan penelitian deskriptif dengan pendekatan cross-sectional. Subjek merupakan mahasiswa Fakultas Kedokteran Universitas Airlangga yang telah menjalani pelatihan BHD dan lulus dalam ujian setelahnya. Lima puluh dua mahasiswa diminta untuk mempraktekkan kembali teknik pemberian BHD dan dinilai menggunakan daftar penilaian modifikasi dari penilaian ketrampilan BHD milik American Heart Association (AHA). Hasil: Persentase mahasiswa yang melakukan dengan benar, antara lain: periksa kesadaran-verbal

Background A right bundle branch block (RBBB) is rarely found in patients with myocardial infarction (MI). In addition, back pain is an atypical complaint in patients with angina. Case A 77-year-old Javanese male was admitted with middle back pain that he had had for several months but that had become worse in the past week. He received an oral nonsteroidal anti-inflammatory drug as analgesic therapy but the pain did not improve. The patient came to the emergency room and an electrocardiogram (ECG) showed complete RBBB and first-degree atrioventricular block. Three days after hospital admission, his chief complaint of pain had worsened, and ECG showed new deep arrow-head inverted wave at V3–V6, II, III, and aVF, as well as infero-anterolateral ischemia. The coronary angiography revealed 95% critical stenosis in left circumflex artery. Discussion It is a challenge for clinicians to recognize and carefully assess a patient’s complaints even if they are admitted for pain that is “atypical” of MI. When ECG shows changes, clinicians need to pay attention to a tricky, hidden, and life-threatening occlusion of the coronary artery.

A male was admitted for middle back pain a month prior and became heavier in a week. The patient came to the emergency room of a hospital and the ECG showed complete RBBB. After Day-3 inpatient, the chief complaint was worsening and ECG showed ischemia sign of infero-anterolateral.

Background Dyslipidemia is a major risk factor of cardiovascular disease, many studies have shown that lipid ratios can be used to predict cardiovascular disease more effectively than individual lipid levels. Objective/Aims This study aims to evaluate the potential risk factors contributing to high Castelli Risk Index–I (CRI–I) in police officer. Methods This observational-descriptive with cross-sectional design study enrolled 3,018 members of East Java police officer. Data was obtained using physical and laboratory examinations that includes systolic blood pressure (SBP), diastolic blood pressure (DBP), body mass index (BMI), low density lipoprotein-C (LDL–C), high density lipoprotein–C (HDL–C), triglyceride (TG), total cholesterol (TC). BMI was classified into < 25 (normal BMI) and > 25 (higher than normal BMI). High blood pressure (BP) was defined as SBP ≥ 140 mmHg and/or DBP ≥ 90 mmHg. CRI-I was calculated using the formula of TC/HDL–C and was defined >5 as at risk and <5 as normal. Statistics were performed on SPSS version 25 and cross-tabulation test was performed on the CRI–I, BP, and BMI in a table form. Result 927 (30.7%) respondents had a CRI–I score > 5. Result of the cross-tabulation test of the high CRI–I score with the physical examination showed association with high BP (OR=1.394; p=0.0), and higher than normal BMI (OR=1.184; p=0.043). Conclusion There was a significant associations between high CRI-I and high blood pressure and higher than normal BMI among a clinical sample of Police Officers.
