Resistance Training Added to Aerobic Interval Training to Improve Aerobic Capacity and Muscle Mass in Women With Coronary Artery Disease

The goal of this clinical trial is to find out whether partly replacing aerobic interval training (AIT) with resistance training (RT) leads to greater improvements in physical fitness and muscle mass in women with coronary artery disease (CAD) during cardiac rehabilitation. The main questions this study aims to answer are: * Does combining RT (squats and pulling exercises with weights) with a reduced amount of AIT (cycling) improve aerobic fitness in the same way as AIT alone? * Does the combined training lead to greater improvements in muscle mass compared with AIT alone? * Does slow-speed RT (slower lowering phase) result in lower heart rate and blood pressure during exercise compared with normal-speed RT? Researchers will compare three exercise programs: * AIT only (control group), * AIT combined with normal-speed RT (1-second lifting, 2-second lowering), * AIT combined with slow-speed RT (1-second lifting, 5-second lowering). Participants will take part in a 12-week cardiac rehabilitation program and will train three times per week. At the start and end of the program, participants will complete a cycling fitness test, body composition assessment, blood sampling, two strength tests, and quality-of-life questionnaire.

Korean NIRS-IVUS Multicenter Registry

Heart diseases known as the second cause of death in Koreans are coronary artery diseases such as angina and myocardial infarction. Coronary artery disease occurs when fat components, such as cholesterol, accumulate in the body. When these fat components are deposited in blood vessels, blood vessels' walls become thick, and the blood vessels narrow, which interferes with circulation. Without smooth circulation, the heart muscle does not function properly because the supply of oxygen and nutrient-rich blood, which is necessary for the heart to function normally, is not properly supplied. It leads to angina pectoris and chest pain and can cause myocardial infarction or even heart attack. Coronary artery disease in various aspects has a high mortality rate when it occurs in old age. The methods currently used for diagnosis and treatment are coronary angiography, percutaneous coronary intervention (PCI), and myocardial partial blood flow reserve history. There is a wide variety of tests (Fractional Flow Reserve, FFR), near-infrared spectroscopy intravascular ultrasound (NIRS-IVUS). In addition to the various aspects and treatment methods of this disease, treatment is often difficult, so the clinical significance is great. In the case of PCI, one of the methods of examination and treatment, the National Cardiovascular Data Registry (NCDR) has been established to establish guidelines for improving patient prognosis after surgery in the United States. NCDR, which started with the American College of Cardiology (ACC) initiative, is currently in an indispensable position for establishing clinical practice guidelines such as monitoring treatment-related indicators, quality improvement (QI), and clinical research. In charge. Besides, in recent years, the use of new drugs or new devices (Post-Market Surveillance), real-time risk estimation, and personalized planning is increasing. Research to analyze the prognosis of various aspects of coronary artery disease, tests, and procedures has been constantly conducted, but comprehensive studies that can be used to improve the overall treatment are considered to be insufficient. At this point, a comprehensive study is required to establish clinical guidelines and to develop them continuously. In particular, the area that needs research is whether or not future events can be prevented using vascular imaging. Studies have shown that if lipids are actively treated with statins, the lipid component of atherosclerotic plaques can be significantly reduced in just a few weeks. Suggests. According to the results of a YELLOW (Reduction in Yellow Plaque by Aggressive Lipid-Lowering Therapy) study published in 2012 based on a near-infrared spectroscopy-vascular ultrasound analysis, the active treatment group of statins showed the lipid-core burden index compared to the standard treatment group. ) showed a significant decrease. Accordingly, this study collects all comprehensive indicators such as test methods, test results, procedures, and treatment results for all patients undergoing near-infrared spectroscopy-vascular ultrasound treatment in Korea, including this institution, A comprehensive study of the disease registry related to the near-infrared spectroscopy-vascular ultrasound procedure is conducted to determine the type of disease, the number of affected vessels, and disease-related indicators.
