Sodium-glucose cotransporter 2 (SGLT2) inhibitors have transformed the treatment of both cardiovascular and renal diseases. Although originally developed for glycemic control in type 2 diabetes mellitus, these agents have demonstrated significant benefits by reducing cardiovascular events and slowing the progression of kidney disease, even in patients without diabetes. Landmark trials, including EMPA-REG OUTCOME, CANVAS, DECLARE-TIMI 58, and DAPA-HF, consistently demonstrated reductions in heart failure hospitalizations and renal deterioration among patients at high cardiovascular risk. However, many of these studies excluded patients with advanced chronic kidney disease (CKD), limiting the generalizability of their findings for this population. More recent investigations, such as CREDENCE, DAPA-CKD, and EMPA-KIDNEY, have focused on patients with CKD and confirmed that SGLT2 inhibitors offer significant renal and cardiovascular protection regardless of diabetic status. This review summarizes key clinical trials, outlining their design and outcomes with a particular emphasis on inclusion and exclusion criteria and the implications for CKD populations. Further, it discusses the practical application and safety considerations of SGLT2 inhibitors in nephrology, underscoring their emerging role as a fundamental therapeutic strategy in CKD management.

The main mechanism of Takotsubo cardiomyopathy (TCM) is catecholamine-induced acute myocardial stunning. Pheochromocytoma, a catecholamine-secreting tumor, can cause several cardiovascular complications, including hypertensive crisis, myocardial infarction, toxic myocarditis, and TCM. A 29-year-old woman presented to our hospital with general weakness, vomiting, dyspnea, and chest pain. The patient was nullipara, 28 weeks’ gestation, and had a cachexic morphology. Her cardiac enzyme levels were elevated and bedside echocardiography showed apical akinesia, suggesting TCM. The next day, she could not feel the fetal movement, and an emergency cesarean section was performed. After delivery, the patient experienced cardiac arrest and was transferred to the intensive care unit for cardiopulmonary resuscitation (CPR). Spontaneous circulation returned after 28 minutes of CPR, but cardiogenic shock continued, and extracorporeal membrane oxygenation (ECMO) was initiated. On the third day of ECMO maintenance, left ventricular ejection fraction improved and blood pressure stabilized. On the eighth day after ECMO insertion, it was removed. However, complications of the left leg vessels occurred, and several surgeries and interventions were performed. A left adrenal gland mass was found on computed tomography and was removed while repairing the leg vessels. Pheochromocytoma was diagnosed and left adrenalectomy was performed.

Cardiac disease is the second leading cause of mortality in Korea and the main cardiac disease is acute myocardial infarction (MI). Timely primary coronary intervention is the main treatment for acute MI and delay from symptom onset to intervention is the most important determinant of the prognosis and incidence of ischemic cardiomyopathy after acute MI. Treatment delay includes patient delay and system delay. The latter includes transfer and in-hospital delays. In-hospital delay improved greatly after introducing the critical pathway to Korea. However, there is still much room to improve patient and transfer delay.

OBJECTIVES: The escalating burden of cardiovascular disease (CVD) is a critical public health issue worldwide. CVD, especially acute myocardial infarction (AMI) and stroke, is the leading contributor to morbidity and mortality in Korea. We aimed to develop algorithms for identifying AMI and stroke events from the National Health Insurance Service (NHIS) database and validate these algorithms through medical record review. METHODS: We first established a concept and definition of “hospitalization episode,” taking into account the unique features of health claims-based NHIS database. We then developed first and recurrent event identification algorithms, separately for AMI and stroke, to determine whether each hospitalization episode represents a true incident case of AMI or stroke. Finally, we assessed our algorithms’ accuracy by calculating their positive predictive values (PPVs) based on medical records of algorithm- identified events. RESULTS: We developed identification algorithms for both AMI and stroke. To validate them, we conducted retrospective review of medical records for 3,140 algorithm-identified events (1,399 AMI and 1,741 stroke events) across 24 hospitals throughout Korea. The overall PPVs for the first and recurrent AMI events were around 92% and 78%, respectively, while those for the first and recurrent stroke events were around 88% and 81%, respectively. CONCLUSIONS We successfully developed algorithms for identifying AMI and stroke events. The algorithms demonstrated high accuracy, with PPVs of approximately 90% for first events and 80% for recurrent events. These findings indicate that our algorithms hold promise as an instrumental tool for the consistent and reliable production of national CVD statistics in Korea.
