Cardiovascular diseases pose a significant health and economic burden worldwide, with coronary artery disease still recognized as a major problem. It is closely associated with hypertension, diabetes, obesity, smoking, lack of exercise, poor diet, and excessive alcohol consumption, which may lead to macro- and microvascular abnormalities in the heart. Coronary artery stenosis reduces the local supply of oxygen and nutrients to the myocardium and results in reduced levels of myocardial perfusion, which can lead to more severe conditions and irreversible damage to myocardial tissues. Therefore, accurate evaluation of myocardial perfusion abnormalities in patients with these risk factors is critical. As technology advances, magnetic resonance myocardial perfusion imaging has become more accurate at evaluating the myocardial microcirculation and has shown a powerful ability to detect myocardial ischemia. The purpose of this review is to summarize the principle, research progress of acquisition and analysis, and clinical implementation of cardiovascular magnetic resonance (CMR) myocardial perfusion imaging.

Background: Cardiac ischemia reperfusion (I/R) injury is a serious consequence of reperfusion therapy for myocardial infarction (MI). Peptidylarginine deiminase 4 (PAD4) is a calcium-dependent enzyme that catalyzes the citrullination of proteins. In previous studies, PAD4 inhibition protected distinct organs from I/R injury by preventing the formation of neutrophil extracellular traps (NETs) and attenuating inflammatory responses.

Intense hepatobiliary uptake of [Tc]Tc-sestamibi in myocardial perfusion scintigraphy (MPS) often degrades image quality by obscuring the inferior myocardial wall, leading to equivocal studies. While nonpharmacological interventions are inconsistent, the choleretic agent ursodeoxycholic acid (UDCA) could potentially accelerate hepatic clearance. The effectiveness of a convenient, single-dose UDCA intervention has not been rigorously evaluated.

Blood perfusion in cardiac tissues involves intricate interactions among vascular networks and tissue mechanics. Perfusion deficit is one of the leading causes of cardiac diseases, and modeling certain cardiac conditions that are clinically infeasible, invasive, or costly can provide valuable supplementary insights to aid clinicians. However, existing homogeneous perfusion models lack the complexity required for patient-specific simulations.

In Tl myocardial perfusion single-photon emission computed tomography (SPECT), gastric wall uptake can impact the inferior wall. This study aimed to evaluate the effectiveness and usefulness of the masking on un-smoothed image (MUS) method for Tl myocardial perfusion SPECT. A hemispherical gastric wall phantom was created to simulate the gastric fundus located closest to the myocardium, and the activity was enclosed to achieve an SPECT count ratio against the myocardium equivalent to that observed in clinical practice.

Rationale And Objectives: The prognostic implications of myocardial perfusion imaging (MPI) are imperative to provide proper management of coronary artery disease (CAD). This study aimed to quantify the long-term prognostic value of MPI under routine clinical conditions.
Materials And Methods: This single-center retrospective cohort study evaluated all-cause mortality and cause-specific survival according to MPI findings in patients with suspected or known CAD who underwent diagnostic evaluation or assessment of myocardial ischemia and viability in a tertiary referral cardiovascular center.
