Effects of Pilates Breathing Versus Diaphragmatic Breathing on Oxygen Saturation and Heart-Rate Variability in Post-Percutaneous Coronary Intervention Patients

Percutaneous Coronary Intervention (PCI) is a common procedure used to restore coronary blood flow in patients with coronary artery disease. Post-PCI patients may experience reduced exercise tolerance, altered breathing patterns, and autonomic imbalance, which may affect oxygen saturation and heart-rate variability (HRV). Breathing exercises are simple, non-pharmacological interventions that may support early recovery. This randomized controlled trial aims to compare the effects of Pilates breathing and diaphragmatic breathing on oxygen saturation and HRV in hemodynamically stable post-PCI patients. A total of 36 participants will be randomly allocated into two groups using a sealed opaque envelope method. The Pilates breathing group and diaphragmatic breathing group will receive supervised breathing exercises for 2 consecutive days, with three sessions per day, in addition to routine care. Oxygen saturation will be assessed using a pulse oximeter, while HRV will be measured using a Polar H10 chest belt. Pre- and post-intervention measurements will be compared between the two groups.

Clinical Impact of DCB-based Versus DES-based Intervention in Patients With MVCAD

This study aimes to compare the clinical outcomes of drug-coated balloon-based percutaneous coronary intervention (DCB-based PCI) and drug-eluting stent-based percutaneous coronary intervention (DES-based PCI) in patients with multivessel coronary artery lesions measuring 2.25 mm to 4.0 mm in diameter through a prospective, multicenter, active-controlled, randomized, investigator-initiated clinical trial.

DAN-RELEASE - Reconsidering Long-Term Aspirin in the Elderly Patients With Stable Ischemic Heart Disease

DAN-RELEASE is a national, randomized, registry-based trial including 7,000 participants in Denmark. The trial aims to determine whether discontinuation of long-term aspirin therapy is non-inferior to continued aspirin therapy in older adults with stable ischemic heart disease. Long-term aspirin therapy is recommended for patients with established ischemic heart disease. However, among clinically stable patients years after percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), or myocardial infarction (MI), the evidence supporting lifelong aspirin therapy is limited. At the same time, the risk of serious bleeding increases with age. DAN-RELEASE will therefore compare aspirin discontinuation with continued aspirin therapy in adults aged 65 years or older with stable ischemic heart disease who have remained free from ischemic events for at least two years. The trial will assess whether discontinuing aspirin is non-inferior to continued treatment with respect to cardiovascular and bleeding outcomes.

Inclisiran Versus Placebo for the Prevention of Major Adverse Cardiovascular and Limb Events in Patients Undergoing Percutaneous Coronary Intervention or Peripheral Endovascular Intervention

V-INTERVENTION will evaluate the effectiveness of inclisiran in preventing major cardiovascular and limb events in patients receiving percutaneous coronary or peripheral arterial revascularization. Inclisiran is a subcutaneous, twice-yearly injection that is FDA-approved as an adjunct with statin therapy and on the market to lower LDL-C in high-risk populations.

Aspirin 50mg vs 100mg Combined With P2Y12 Inhibitor After PCI

This is a randomized, open-label, active-controlled, non-inferiority clinical trial (the ASPIRE-LD trial) conducted in China. It aims to compare the efficacy and safety of low-dose aspirin (50 mg once daily) versus standard-dose aspirin (100 mg once daily), both in combination with a P2Y12 inhibitor, in patients who have successfully undergone percutaneous coronary intervention (PCI) and plan to receive at least 12 months of dual antiplatelet therapy (DAPT). A total of 2640 eligible patients will be randomly assigned in a 1:1 ratio to receive either 50 mg or 100 mg of enteric-coated aspirin daily, plus a P2Y12 inhibitor (ticagrelor 90 mg twice daily or clopidogrel 75 mg once daily, prescribed according to routine clinical practice). All participants will be followed for 12 months after randomization. The primary goal is to verify that 50 mg aspirin is non-inferior to the 100 mg standard dose in preventing major adverse cardiac and cerebrovascular events (MACCE: cardiovascular death, non-fatal myocardial infarction, definite/probable stent thrombosis, and ischemic stroke) at 12 months post-PCI. If non-inferiority is confirmed, the study will further test whether 50 mg aspirin reduces clinically relevant bleeding events (BARC type 2, 3, or 5) better than the standard dose. The study is sponsored by the First Hospital of Jilin University and will be carried out in 10-15 tertiary hospitals across China. Its findings will provide evidence for optimizing aspirin dosing in post-PCI DAPT.

Efficacy and Safety of Colchicine After PCI

Colchicine (0.5 mg/day) was recommended by the U.S. Food and Drug Administration in 2023 for the anti-inflammatory treatment of coronary heart disease (CHD). However, colchicine is still not approved for CHD treatment in China. There is no large-scale clinical evidence that colchicine can be used to treat Chinese patients with CHD. Considering the low body weight of the East Asian population, it is unclear whether the recommended standard dose (0.5 mg/day) is suitable for Chinese patients. Therefore, we need to further explore the effects of different doses of colchicine on the efficacy and safety of clinical endpoints in the Chinese population with CHD. This study is a multicenter, prospective, randomized, controlled, double-blind, event-driven clinical study conducted in China. The primary objective of this study is to determine whether long-term treatment with different doses of colchicine reduces the incidence of cardiovascular events in Chinese patients undergoing PCI. The secondary objective is to determine the safety of long-term treatment with different doses of colchicine in this patient population.

The primary hypothesis is that P-CAB (experimental arm) would non-inferior to PPI (standard arm) with respect to the rate of the primary composite end point of GI events at 12 months after randomization.

Precision PCI Registry

The feasibility and clinical benefit of using a patient's genotype to guide antiplatelet therapy prescribing has been demonstrated. However, a more precise understanding of who to genotype, what to include on a genetic testing panel, and how to change antiplatelet therapy based on genotype results and other patient-specific factors is needed to optimize the impact of genotype-guided antiplatelet therapy on patient outcomes. The Precision PCI registry is a collaboration between the University of Florida, Gainesville and Jacksonville, USA, the University of North Carolina, Chapel Hill, USA, and University of Maryland, Baltimore, USA. This registry will include a diverse population of patients who undergo Percutaneous Coronary Intervention and clinical CYP2C19 genotyping, assess clinical outcomes over 12 months and collect DNA samples for additional genotyping, and conduct pharmacodynamic analysis of platelet function in a subset of patients. Objectives of the study: 1. Define the influence of African ancestry and other patient-specific factors on clinical outcomes with genotype-guided antiplatelet therapy following PCI in a real-world setting 2. Evaluate the safety and effectiveness of genotype-guided de-escalation of antiplatelet therapy (i.e., switching to less potent antiplatelet therapy) after PCI in a real-world setting 3. Elucidate the effect(s) of genotypes beyond CYP2C19 on platelet reactivity and clinical outcomes with clopidogrel after PCI

Improving Cardiac Rehabilitation Exercise Using Target Heart Rate Trial

The goal of this clinical trial is to compare two types of exercise prescriptions in cardiac rehabilitation eligible older adults (60 years or older) with heart disease. The investigators found in a single site pilot trial (insert NCTxxx) that one exercise prescription was better and are now repeating this study in a larger population at two sites (Baystate Medical Center, Springfield MA and Henry Ford Health System, Detroit MI). The main questions the investigators aim to answer are: 1. Compare two different exercise prescriptions in cardiac rehabilitation on exercise outcomes 1. Graded exercise test +Target heart rate range prescription \[GXT-THRR\] 2. Rating of perceived exertion (RPE) 2. What is the role of psychological feedback on fitness outcomes during cardiac rehabilitation and physical activity outside of cardiac rehabilitation. 3. What are the long-term clinical outcomes between the two exercise prescriptions Participants will be asked to: * Complete surveys about physical activity, exercise anxiety, exercise efficacy, and fears about exercising * Perform fitness measures (6-minute walk test, balance tests, stand to sit tests, a 400 meter walk, and handgrip strength) * Attend at least 18 sessions of cardiac rehabilitation after they are randomized to their exercise prescription group * Wear a heart rate monitor and a physical activity monitor per study protocol Participants will be randomized (flip of a coin) to either receive a graded exercise test and psychoeducational feedback or lifestyle education (nutrition for cardiac). The graded exercise test will be used to create a personalized exercise prescription with the target heart rate range calculated from the test and the lifestyle education group will use their ratings of perceived exertion for their exercise prescription.
