Coronary Flow Reserve, Inflammation, and Myocardial Strain

JACC: Basic to Translational Science, 2023
Summary: Inflammation is a key determinant of cardiovascular outcomes, but its role in heart failure is uncertain. In patients with cardiometabolic disease enrolled in the prospective, multicenter ancillary study of CIRT (Cardiovascular Inflammation ...

Non-Invasive Assessment of Coronary Microvascular Dysfunction: From Flow Quantification to Clinical Decision Making [PDF]

Medicina
Coronary microvascular dysfunction (CMD) is a major mechanism of myocardial ischemia and adverse cardiovascular outcomes in patients with angina or dyspnea, both in the absence and in the presence of obstructive coronary artery disease.

Circulating Ectonucleotidases Signal Impaired Myocardial Perfusion at Rest and Stress

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background Ectonucleotidases maintain vascular homeostasis by metabolizing extracellular nucleotides, modulating inflammation and thrombosis, and potentially, myocardial flow through adenosine generation.

Relation of cardiac adipose tissue to coronary calcification and myocardial microvascular function in type 1 and type 2 diabetes

Cardiovascular Diabetology, 2020
Background Cardiac adipose tissue may have local paracrine effects on epicardial arteries and the underlying myocardium, promoting calcification and affecting myocardial microcirculation. We explored whether the total amount of cardiac adipose tissue was
