Pharmacologic Stress Myocardial Perfusion Imaging with SPECT and PET in Liver Transplant Candidates: Physiologic Limitations, Current Evidence, and Future Directions

Current Cardiology Reports · 2026

This review examines how cirrhosis affects SPECT and PET myocardial perfusion imaging in liver transplant candidates. It explains the limitations of relative perfusion imaging and the potential value of quantitative PET, while emphasizing that transplant-specific thresholds and effects on clinical outcomes remain unvalidated.

Association of Rheumatoid Arthritis with Major Adverse Cardiovascular Events Despite Normal Myocardial Perfusion Imaging

American Journal of Preventive Cardiology

A retrospective matched-cohort study found that rheumatoid arthritis was associated with higher rates of major adverse cardiovascular events even when myocardial perfusion imaging showed no ischemia. The findings highlight residual cardiovascular risk that a normal SPECT or PET perfusion study may not capture.

Evaluating the Quality of Cardiovascular Disease Information From AI Chatbots: A Comparative Study

PMID: 40821349

This comparative study evaluated the readability, quality, understandability, and actionability of four AI chatbots answering common questions about heart attacks, heart failure, and arrhythmias. Performance varied across the models and topics tested, underscoring the need to evaluate patient-facing cardiovascular information beyond factual accuracy alone.

Lipoprotein(a): A Review of Risk Factors, Measurements, and Novel Treatment Modalities

PMID: 38415744

This review examines lipoprotein(a), or Lp(a), as a cardiovascular risk factor, including the evidence linking it to atherosclerotic disease, challenges in measurement, and emerging treatment approaches. It brings together observational and genetic evidence to explain why Lp(a) matters in cardiovascular risk assessment.
