Aim: To assess extent and localization of coronary artery lesions in patients with painless myocardial ischemia.
Material And Methods: Tredmill stress-echocardiograghy, Holter ECG monitoring and coronary angiography were carried out in 59 male patients (age 30-72, mean 54.5 years) with either angina pectoris or painless ischemia.
Results: Among patients with painless ischemia 50% had 2-vessel disease, mostly with right coronary artery involvement (87.5%) and there was no case of left main stenosis. Patients with angina were characterized by significantly higher index of obstruction (p<0.005) and often had multivessel coronary artery disease (48.8%).
Conclusion: Patients with effort angina compared with those with painless ischemia had more extensive and severe coronary artery involvement while the latter more often had right coronary artery stenoses.

Patient-reported outcome measures (PROMs) are vital tools in cardiovascular disease (CVD) research and care, providing insights that complement traditional clinical outcomes like mortality and morbidity. PROMs capture patient experiences with CVD, such as quality of life, functional capacity, and emotional well-being, allowing clinicians to assess how interventions impact daily life. PROMs are integral to cardiovascular investigations as well as management, especially in chronic conditions and rehabilitation, where they inform on the impact of personalized care plans by tracking symptom progression and patient adherence.

Although human genetics has substantial potential to illuminate novel disease pathways and facilitate drug development, identifying causal variants and deciphering their mechanisms remain challenging. We believe these challenges can be addressed, in part, by creatively repurposing the results of molecular trait genome-wide association studies (GWASs). In this review, we introduce techniques related to molecular GWASs and unconventionally apply them to understanding , a human coronary artery disease risk locus.

The aim of this study was to describe the features of myocardial lymph flow using a new combined method of visualization of the lymphatic system. The study was performed on pig hearts harvested from a local slaughterhouse. The original dye, consisting of lipid-soluble chlorophyll and lipiodol, was injected stepwise into the lymphatic vessels.

Introduction: Off-pump coronary artery bypass graft surgery (OPCAB) has been suggested as superior to on-pump coronary artery bypass graft surgery (ONCAB) in certain high-risk subgroups, but its benefit in patients with chronic obstructive pulmonary disease (COPD) remains controversial. This meta-analysis aimed to evaluate OPCAB versus ONCAB outcomes in COPD patients.
Methods: We followed PRISMA guidelines and searched PubMed, Embase, and the Cochrane Library in August 2024 for studies comparing OPCAB and ONCAB in COPD patients.
