The Basic Lecture Course (BLC) hands-on seminar has long been a core educational activity organized by the U-40 of the Japanese Society for Cardiovascular Surgery at the branch level. However, due to the COVID-19 pandemic, in-person seminars were suspended for an extended period. Since 2022, the seminars have gradually resumed, and in 2025, a branch-based hosting system was introduced. Nevertheless, several challenges unique to the post-pandemic era have become evident. In the Hokkaido Branch, BLC hands-on seminars were held in July 2024 and August 2025. This report presents the outlines and management processes of these two events, summarizes the results of participant surveys, and discusses future challenges and perspectives for the operation of BLC hands-on seminars.

Purpose: To compare the effects of aging in patients with acute myocardial infarction (AMI) on their clinical background and hospitalization progress, and to examine the relationships between age and these factors.
Subject: One hundred and fifty-three patients who experienced cardiac rehabilitation after percutaneous coronary intervention (PCI) (63.8±11.1 y.o, 126 men, 27 women).
Method: The patients were divided into the middle aged group (<65 y.o, n=84), young old group (65 to 74 y.o, n=44), and old group (75 y.o≥ n=25). The differences between groups were examined in respect of 13 items about clinical backgrounds (responsibility coronary arteries, CKmax, LVEF, residual stenosis, hypertension, diabetes, hyperlipemia, smoking, and BMI) and hospitalization progress (cardiac complications, locomotorium disabilities, abnormality as 200mECG, and duration of hospitalization).
Results: Left veticular ejection fraction (LVEF) was significantly lower in the old group than in the young old group. The old group had a high rate of residual stenosis. In the coronary risk factors, all of the groups had hypertension at a high rate of 54.5% or over. The middle aged group and young old group had diabetes at about 38%. The middle aged group was prone to hyperlipemia, and had significantly a high smoking rate. Body mass index (BMI) was significantly higher in the middle aged group than in the old group. In hospitalization progress, the old group had a high rate of cardiac complications and locomotorium disability. The duration of hospitalization was significantly longer in the old group than in the other groups.
Conclusion: It would be necessary to give middle-aged persons educational guidance for the improvement of the coronary risk factors, and to provide the old persons with the suitable rehabilitation programs considering various complications.
