Objective: To investigate whether exercise would induce myocardial ischemia in patients with coronary artery ectasia without significant coronary stenosis.
Methods: A total of 41 patients (male 29, female 12) with coronary artery ectasia without significant coronary stenosis, confirmed by selective coronary angiography, were enrolled in the study group. Forty-one patients with normal coronary arteries were in the control group. All the patients received a clinical examination and treadmill exercise before selective coronary angiography.
Results: Eighteen patients (43.9%) had typical angina in the study group with respect to two patients in the control group (chi(2)=10.498, P=0.001). In the study group, 32 cases had positive treadmill test with respect to five cases in the control group (chi(2)=35.903, P<0.0001).
Conclusion: Patients with coronary artery ectasia without significant coronary stenosis could get typical angina. Exercise could induce myocardial ischemia which should be paid attention to.

Background: Atrial fibrillation (AF) is the most prevalent arrhythmia encountered in clinical practice. Triglyceride glucose index (Tyg), a convenient evaluation variable for insulin resistance, has shown associations with adverse cardiovascular outcomes. However, studies on the Tyg index's predictive value for adverse prognosis in patients with AF without diabetes are lacking.

We investigated clinical factors and biochemical markers associated with amygdalar metabolic activity evaluated by [F]-fluorodeoxyglucose-positron emission tomography (FDG-PET) in 346 subjects without a history of malignant neoplasms. Univariate regression analysis revealed significant relationships between amygdalar metabolic activity and fasting plasma glucose (FPG), glycated hemoglobin, coronary artery disease (CAD) history, aspirin use, oral hypoglycemic agents (OHAs) use, and asymmetric dimethylarginine (ADMA). In multiple stepwise regression analysis, FPG and CAD history were independently associated with amygdalar metabolic activity.

Background: The Scottish Computed Tomography of the Heart (SCOT-HEART) trial demonstrated that management guided by coronary CT angiography (CCTA) improved the diagnosis, management, and outcome of patients with stable chest pain. We aimed to assess whether CCTA-guided care results in sustained long-term improvements in management and outcomes.
Methods: SCOT-HEART was an open-label, multicentre, parallel group trial for which patients were recruited from 12 outpatient cardiology chest pain clinics across Scotland.

Background: Arterial diseases like coronary artery disease, carotid stenosis, peripheral artery disease, and abdominal aortic aneurysm have high morbidity and mortality, making them key research areas. Their multifactorial nature complicates patient treatment and prevention. Biomarkers offer insights into the biochemical and molecular processes, while social factors also significantly impact patients' health and quality of life.
