At Bangkok Hospital, we believe in Service from the Heart. It is thus appropriate that our 3rd edition continues to see a distinctive and varied contribution from our Cardiac Unit. We are pleased to finally see in print Dr. Gumpanart’s account of how he and his capable team saved a patient’s life with the first emergent primary coronary angioplasty performed in Thailand. Dr. Pradub appraises evidence-based management of Acute decompensated heart failure. Dr. Rattanapan’s case study shows how conservative treatment over a longer period can be used to deal with a large thrombus where standard surgical intervention was inadequate to restore coronary perfusion. Dr. Lertlak details using MRI images to study regional wall motion of the left ventricle, to develop additional quantitative tool, with which to detect impaired myocardial regional wall motion. Dr. Poomiporn describes a rare case of Kawasaki Disease Shock Syndrome in a young child, which if untreated could lead to ischemic heart disease, myocardial infarction or sudden death.
