Background: Real-time (RT) phase contrast (PC) flow MRI can potentially be used to measure blood flow in arrhythmic patients. Undersampled RT PC has been combined with online compressed sensing (CS) reconstruction (CS RT) enabling clinical use. However, CS RT flow has not been validated in a clinical setting.

Aims: Right ventricular (RV) failure causes high mortality in patients with pulmonary arterial hypertension (PAH). RV stroke work index (RVSWi) poses as a potential predictor of outcome. We evaluated how RVSWi by echocardiography (ECHO) or right heart catheterization (RHC) is altered following PAH treatment and if RVSWi is an indicator of outcome in PAH.
View Article and Find Full Text PDFBackground: Right ventricular (RV) dyssynchrony or post systolic contraction (PSC) causes inefficient pumping and has not been investigated as a prognostic marker in pulmonary arterial hypertension (PAH). The objective was to investigate if RV dyssynchrony and PSC are prognostic markers of transplantation-free survival in PAH and if multiple RV views improve prognostication.
Methods: Patients with PAH undergoing cardiovascular magnetic resonance between 2003 and 2021 were included.
Article Synopsis
- The study aimed to explore sex differences in the prevalence of imaging-detected atherosclerosis in men and women, revealing that men are more likely to experience cardiovascular issues such as myocardial infarction.
- Participants aged 50-65 from the SCAPIS study underwent advanced imaging, finding significantly higher rates of coronary and carotid atherosclerosis in men compared to women (e.g., 56.2% vs. 29.5% for coronary atherosclerosis).
- Even after adjusting for factors like hypertension and diabetes, these sex differences in atherosclerosis prevalence persisted, indicating a greater cardiovascular risk for men, with older women showing comparable rates to younger men.
Short- and long-term prognostic performance of exercise ECG and myocardial perfusion SPECT.

Background: Myocardial perfusion SPECT (MPS) and exercise electrocardiography (Ex-ECG) results are of prognostic importance for short-term follow up duration. However, the value of MPS or Ex-ECG findings for long-term risk assessment is less evident as underlying risk factors for ischemic heart disease (IHD) gain in importance.
Objectives: To assess the short- and long-term prognostic value of MPS and Ex-ECG in relation to known risk factors.
