Background and Objectives: Heart failure (HF) is a leading cause of hospitalization and death worldwide. The Steady Movement with Innovating Leadership for Heart Failure (SMILE HF) aims to evaluate the clinical characteristics, management, hospital course, and long-term outcomes of patients hospitalized for acute HF in South Korea. Methods: This prospective, observational multicenter cohort study was conducted on consecutive patients hospitalized for acute HF in nine university hospitals since September 2019. Enrolment of 2000 patients should be completed in 2024, and follow-up is planned through 2025. Results: Interim analysis of 1,052 consecutive patients was performed to understand the baseline characteristics. The mean age was 69±15 years; 57.6% were male. The mean left ventricular ejection fraction was 39±15%. The prevalences of HF with reduced ejection fraction, HF with mildly reduced ejection fraction, and HF with preserved ejection fraction were 50.9%, 15.3%, and 29.2%. Ischemic cardiomyopathy (CMP) was the most common etiology (32%), followed by tachycardia-induced CMP (12.8%) and idiopathic dilated CMP (9.5%). The prescription rate of angiotensin-converting enzyme inhibitor/angiotensin receptor blockers/angiotensin receptor/neprilysin inhibitor, beta-blockers, spironolactone, and sodium-glucose cotransporter-2 inhibitors at discharge were 76.8%, 66.5%, 50.0%, and 17.5%, respectively. The post-discharge 90-day mortality and readmission rates due to HF aggravation were 2.0% and 6.4%, respectively. Our analysis reveals the current state of acute HF in South Korea. Conclusions: Our interim analysis provides valuable insights into the clinical characteristics, management, and early outcomes of acute HF patients in South Korea, highlighting the current state and treatment patterns in this population.

Chronic constrictive pericarditis is the end stage of a chronic inflammation that produces a fibrous, thich constricting pericardium with a limitation of a diastolic ventricular filling and eventually systolic ejection as well. We experienced a typical case of constrictive pericarditis and treated successfully by pericardiectomy.

This paper described the establishment of the basic data for the design of the transducer for the detection of plethysmogram, the structure of pulsimeter utilizing the designed transducer and the clinical usefulness of detected waveform of the optical detection method can be utilized as an information of cardiovascular system as physiological theoretical waveform of aorta, and derivative of plethysmogram by piezo electric elements clearly shows the information of incisura which does not appear at the old age and this makes the measuring of ejection time to be easy. The ejection time of average for 42 persons shows 0.324 $\pm$ 0.027 sec. and this value is in good agreement with the theoretical value, and the possibility of measuring the velocity of pulse conduction has been studied.
